a84eb3ac 3Imager 1.010 - 13 Feb 2019
5497656d
TC
4============
5
6General changes:
7
8 - added the add_file_magic() class method for adding magic for new
9 file types to Imager's fairly primitive file magic detection.
10
11 - fixed an embarassing documentation typo in Imager::Test.
12
13 - trying to read from a GIF file with no images now sets an error
14 message. Thanks to Peter Sergeant for reporting this.

16
4321405f
TC
17 - use undeprecated encoding symbols for FT2. This should fix the
18 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
19 Rezic for the report.

TC
22Coverity has come back up read-only, a few more changes:
23
24 - add missing va_end() for bmp.c's write_packed(). CID 185320.
25
26 - similarly for read_packed(). CID 185329.
27
28 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
29 complained about a missing return, Coverity complains about the
30 return. CID 185325.
31
32 - avoid a possible sign extension in imsgi.c. CID 185326.
33
34 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
35 deliberately fall through switch cases. CID 185328.
36
37 - add assertions in callers to i_new_hatch_low() since Coverity
38 complained about some possible inconsistent NULL checks. CID
39 185339. I ended up rearranging this function later.
40
41 - remove pointless NULL checks from i_flipxy() and i_img_destroy().

57cc9afe
TC
45============
46
1456b645
TC
47Critical issue:
48
49 - drawing a filled, anti-aliased circle to the left or right of the
50 image (not within the image at all) would cause a buffer overflow.
51 https://rt.cpan.org/Ticket/Display.html?id=128208
52
a3b721bb
TC
53General changes:
54
55 - to_paletted() and make_palette() now fail (with an error in
56 errstr()) if invalid quantization parameters are supplied.
57
35ec3a87
TC
58 - map() would corrupt a channel if there was a gap in the arrayref of
59 channels. Detected by Coverity. CID 185300.
60
5824f4c2
TC
61 - most numeric parameters to the XS implementation now throw an
62 exception if supplied an unoverloaded reference.
63 https://rt.cpan.org/Ticket/Display.html?id=128208
64
e32d3a7c
TC
65Coverity finally finished a build[1], fixed several of the problems
66found. Coverity went down before I could finish working through them.
1791cbdb 67
8445279e
TC
68High severity:
69
1791cbdb 70 - reading a color-mapped TGA file with an id string would cause a
8445279e 71 double-free if the palette was truncated. CID 185317.
1791cbdb 72
6494c395
TC
73 - mixing scaling to sizes where the accumulator row, the working
74 output row or the working input row didn't fit into the address
75 space could result in memory leaks. This can probably only be
8445279e 76 reproduced on very wide floating-point sample images. CID 185318.
6494c395 77
fc24ca5f 78 - convert an array style function parameter pointer to pointer style
3d7b055c 79 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 80 CID 185343.
3d7b055c 81
8445279e 82 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 83
20c297d4 84 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 85 implementation. CID 185303.
20c297d4 86
fc24ca5f 87 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 88 drawing (it should always end up being set.) CID 185341.
fc24ca5f 89
f7675b46 90 - addi style makemap could potentially read one past the end of an
8445279e 91 array. CID 185337.
f7675b46 92
58ec1fde
TC
93 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
94 would result in read beyond the end of the built-in hatch array.
95 Negative values (which Coverity didn't complain about) could also
8445279e 96 cause problems. CID 185331.
58ec1fde 97
b7346865
TC
98 - the Imager::Color set_internal() interal method no longer
99 calls the over-complicated ICL_set_internal() (which is retained
100 only for the old API.) Coverity complained that this leaked, but
101 this could only occur with an invalid (NULL pointer) color object.
8445279e 102 CID 185323.
b7346865 103
785364c1
TC
104 - the underlying implementation of the map() method could read before
105 the beginning on an allocated array if supplied with inconsistent
106 parameters, which Coverity complained about. No Imager code calls
107 that function with inconsistent parameters, but a
8445279e 108 belt-and-suspenders check was added. CID 185315.
785364c1 109
eb7e48c9
TC
110 - Coverity complained a call to i_getcolors(), used by the
111 implementation of the is_bilevel() method could leave the fetched
8445279e 112 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 113
c1c8b1e9
TC
114 - a numeric combining mode of 13 (eg. as a parameter to
115 Imager::Fill->new())could cause an invalid array read in
116 i_get_combine() due to a fencepost error in validating the combine
8445279e 117 number. CID 185299.
c1c8b1e9 118
59fd0c6b 119Lower severity (according to Coverity):
c4fd43be
TC
120
121 - avoid an unneeded EXTEND() call when the FT1 has_chars()
122 implementation returns 0. CID 185350.
123
124 - avoid accessing a possibly NULL map from MakeMapObject() in a
125 logging call. (GIF) CID 185296.
126
4615ad8d
TC
127 - gradgen() allocated the wrong amount of space (always too much) for
128 the color array. CID 185291.
129
ea3099db
TC
130 - avoid dead code in i_tt_glyph_names(). CID 185321.
131
8b810590
TC
132 - avoid dead code in i_get_anonymous_color_histo(), which is the
133 implementation of getcolorusage(). CID 185327.
134
4eb9a521
TC
135 - avoid dead code in i_ft2_glyph_name(), which is the implementation
136 of glyph_names() for FT2. CID 185342.
137
c028aa12
TC
138 - avoid dead code in i_t1_glyph_names(), which is the implementation
139 of glyph_names() for T1. CID 185322.
140
e7772cea
TC
141 - avoid an unneeded EXTEND() call when the FT2 has_chars()
142 implementation returns 0. CID 185292.
143
596f3eee
TC
144 - the unpack code for ICO/CUR file handling could extend 32-bit
145 unsigned values to 64-bit signed. I believe this is harmless. CID
146 185319.
147
a2ca2b80
TC
148 - remove an unneeded check when terminating the stream for JPEG
149 writing. CID 185347.
150
56ce7446
TC
151 - skip an unneeded check when freeing the combine temp buffer in the
152 fountain filter. CID 185286.
153
154 - check the combine function pointer consistently rather than the
155 combine code in one place in the fountain filter.
156
a3b721bb
TC
157 - error diffusion now validates a custom error diffusion map and reports
158 an error if it's bad. CID 185288.
159
215d9ead
TC
160 - avoid discarding the value of i_io_getc() when scanning numbers in
161 pnm.c. CID 185293.
162
9ca939d0
TC
163 - handle failure to clone the log filehandle when cloning the Imager
164 context object on thread creation. CID 185294.
165
70501294 166 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
167 glyph index with a NULL character map when calculating the glyph
168 for display for FT1. This should be rare. CID 185297.
169
170 - fix a similar bug when calculating whether a glyph is present for
171 has_chars() for FT1. CID 185302.
70501294 172
6fa51f9c
TC
173 - i_img_info() (C API) no longer tries to handle a NULL image object
174 pointer. CID 185298.
175
a2c2d400
TC
176 - re-work testing for size_t overflow for circle/random
177 super-sampling for fountain fills. CID 185304.
178
8e2e2347
TC
179 - don't check if the unsigned size passed to Imager's malloc wrapper
180 (mymalloc) is negative. Left from when that parameter was signed.
181 CID 185305.
182
0c16f204
TC
183 - make some types larger and add a cast to prevent integer overflows
184 when calculating a palette with median cut for extraordinarily
185 large images. CID 185306.
186
748bfdfc
TC
187 - don't check if the unsigned size supplied to
188 im_set_image_file_limits() is negative. CID 185307.
189
57cc9afe 190[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
191build queue, and seemed to have been cancelled by Coverity. A build
192submitted on NYE went through in minutes.

TC
194Imager 1.008 - 31 Dec 2018
195============
196
75e155e1 197 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
198 This allows file formats that store EXIF data as blobs similarly
199 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 200
b5bbf161 201 - added some more file extensions to image file type mappings
75e155e1
TC
202
203 - added add_type_extensions() class method
204
f38e738a
TC
205 - Imager::Files now links to Imager::Install when discussing
206 appropriate libraries.

TC
210============
211
a9fa5463
TC
212 - add png_compression_level tag for writing PNG files.
213
214 - avoid flooring a second time in matrix transform interpolation.
215 https://rt.cpan.org/Ticket/Display.html?id=124001
216
434c2338
TC

220
d1d8320e
TC
221 - improve error reporting for the polygon() method
222
ac3e79fb
TC
223Imager 1.006 - 26 Aug 2017
224============
225
ba7ddbae
TC
226 - the internal i_errors() function now correctly allocates the stack
227 space needed for its result.
228 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
229
230 - t/100-base/020-color.t now uses Imager::Test's test functions
231 instead of its own.
232 https://rt.cpan.org/Ticket/Display.html?id=111993
233
344dda51
TC
234 - write_multi() now returns an error result (a false value) if called
235 with a non-(Imager image object). Previously it would typically
236 crash.
237 https://rt.cpan.org/Ticket/Display.html?id=117878
238
239 - improve the documentation of the jpegquality parameter when
240 writing JPEG files.
241
242 - add code to mitigate CVE-2016-1238, Imager will no longer search the
243 default current directory entry in @INC when searching for file
244 format support modules.

TC
246Imager 1.005 - 16 Apr 2016
247============
248
249It's now been ten years since I switched to the new Changes file in
250release 0.55.
251
cd0109d8
TC
252 - revert the ivdformat probes, they don't work as is and trying to
253 fix them is too much work for now.
254
6f1cbfed
TC
255Imager 1.004_004 - 15 Apr 2016
256================
257
9c45cc49
TC
258 - test that the ivdformat from Config is correct and look for a valid
259 one if it isn't.
260 For the strange Win32 failures.
261
262 - fix a copy and paste error in pod in samples/samp-form.cgi
263
5cea6ea1
TC
264Imager 1.004_003 - 23 Mar 2016
265================
266
bd2d657d
TC
267 - add some extra error reporting to the I/O layers tests, this might
268 help catch a failure seen on Win32.

2f4c4539
TC
271Imager 1.004_002 - 20 Mar 2016
272================
273
735b3e7b
TC
274 - don't use the seek() method on opened() handles in
275 t/200-file/400-basic.t. In older versions of perl such handles are
276 only IO::Handle objects, not IO::File, and don't have a seek()
277 method.

TC
279Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
280================
281
08914ed1
TC
282 - re-work the t/200-file/400-basic.t to correctly handle failures
283 It's custom ok() function didn't have a prototype and didn't use scalar().
284 This caused ok() to use the note instead of the value being tested when
285 the method called returned an empty list. For an example of the problem
e6226ce5 286 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 287
a2791e47
TC
288 - remove some noise from when Imager tried to work with bugs in old
289 versions of giflib. I can't do much about the new bugs.
08914ed1 290
e6226ce5
TC
291 - the new autolevels filter (Imager 0.99) used an integer for the
292 sample scaling factor which caused the top output level to be too
293 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
294 https://rt.cpan.org/Ticket/Display.html?id=111871
295
e6226ce5 296 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
297 minimum and maximum luminance from the histogram. This slightly
298 reduced the contrast of the output image.
299 https://rt.cpan.org/Ticket/Display.html?id=111871
300
301 - the new autolevels filter now uses a lookup table for 8-bit images
302 to avoid a floating point multiply for each sample.
303 https://rt.cpan.org/Ticket/Display.html?id=111871
304
e6226ce5
TC
305 - fixed several memory leaks detected by valgrind:
306
307 - addcolors() leaked the temporary array of colors supplied to the
308 internal API
309
310 - make_palette() leaked the temporary image array (not the images
311 themselves) passed to the internal API.
312
313 - combine()/i_combine() leaked its working row buffers
314
315 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
316 buffer if there were too many colors
317
318 - getcolorcount()/i_count_colors() leaked the sample buffer if
319 there were too many colors.
320
321 - the nearest_color filter (undocumented until I find a use for it)
322 leaked both temporaries passed to the API and internal buffers
323
a2791e47
TC
324 - the internal process of upgrading a paletted image to a direct
325 color image would leak a context object reference count.
326
327 - a write failure when writing to a GIF file could leak memory.
328
329 - failing to write to a 1-bit/pixel ICO image could leak memory.
330
331 - Imager no longer deliberately leaks the context object from the
332 initial thread. This was done to ensure there was always a context
333 object available, but the code that needed that now handles the
334 lack correctly,
335
e6226ce5
TC
336 - fixed some uninitialized memory usage detected by valgrind:
337
338 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
339 i_matrix_transform_bg() didn't initialize a working color value
340 if there was zero pixel coverage.
341
342 - i_ft2_cp() didn't initialize the complete color when producing an
343 intermediate image. This caused uninitialized value usage when
344 logging the color.

TC
346Imager 1.004 - 8 Nov 2015
347============
348
5ebfb369
TC
349 - Imager::Color::Table is now pre-loaded by the preload() method.
350 https://rt.cpan.org/Ticket/Display.html?id=104896
351
352 - fix an assertion triggered under perl 5.23.4.
353 Thanks to A. Sinan Unur for the report and the patch.
354
7b638aba
TC
355 - Imager->new can now be used to read raw image files.

f7160b21 357 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
358
359 - deal with output changes from Pod::Spell

TC
362Imager 1.003 - 12 May 2015
363============
364
0fda3cfd
TC
365 - update 1.002 release notes to include the center change for filled
366 circle drawing.
367
368 - flood_fill() would escape beyond a 4-connected space under some
369 circumstances.
370 Added many more flood_fill() tests.

TC
373Imager 1.002 - 3 Apr 2015
374============
375
334b8922
TC
376 - drawing anti-aliased filled circles is now 10 to 50 times faster
377 depending on the size of the circle.
0fda3cfd
TC
378 This also changed the center from being the center of the pixel to
379 being the top left of the pixel to match the filled arcs drawn by
380 arc().
334b8922
TC
381 https://rt.cpan.org/Ticket/Display.html?id=101682
382
383 - enhancements to polygon filling:
384
385 - added a mode parameter to control how overlapping regions behave
386
387 - added a polypolygon() method to fill more than one polygon at a
388 time
389
390 - polygon filling is now exposed through the API.
391
45c8e262
TC
392 - added colormodel(), alphachannel() and colorchannels() methods.
393 These were added for two reasons:
394
395 - a future version of Imager may allow the number of channels in
396 an image to not directly represent the color model of an image.
397 eg. a greyscale TIFF image with multiple alpha channels.
398
399 - a future version of Imager may allow an image to be read without
400 translation, for example a TIFF file that contains measurements
0fda3cfd 401 from an instrument. Currently Imager transforms the samples into
d96c4de8 402 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
403 the value back.
404
405 An untranslated image would be unusable as image data, so
406 colormodel() would return "unknown" in this case.
407
408 Similarly a CMYK image might be returned as an "unknown" color
409 model image, if the caller chooses to disable translation to
410 RGB.

453 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
454 the blue channel in the generated palette, and allow each color
455 component to be in the range 100..255 instead of just 100..254.
456 Thanks to Ralf Neubauer.

458
459 - revert "improved the XS for i_io_read() and i_io_raw_read()"
460 This caused problems with older perls and didn't provide much of a
461 performance improvement.
462

490 - Imager::IO->new_buffer() (and hence Imager->read()'s data
491 parameter) now accepts a reference to a scalar as well as just a
492 plain scalar.

510

TC
516 - Imager::File::PNG now supports libpng 1.6.10.
517 1.6.10 changed CRC errors from benign errors to normal errors,
518 which broke the test which used CRC errors to check for benign
519 error support. Switched to using a 1-bit grey-scale image with a
520 palette to test for benign errors.

524===========
525
f84f86a2
TC
526Incompatible changes:
527
528 - the return value of setpixel() has changed.
529
530 Previously the return values for undrawable pixels vs caller errors
531 changed depending on whether you used the multiple pixel calling
532 mechanism, or the single pixel mechanism.
533
534 Now:
535
536 - for an invalid parameter, such as an unknown colour, or missing
537 parameter, an empty list (or undef in scalar context) is
538 returned, and errstr() is set,
539
540 - otherwise the number of pixels drawn is returned. If none of
541 the pixels could be drawn (they were all outside the image), "0
542 but true" is returned.
543
544 https://rt.cpan.org/Ticket/Display.html?id=87650
545
546Other changes:
547
6ba09ab9
TC
548 - when drawing on an image with an alpha channel where the source
549 minimum is greater than zero, Imager would read from beyond the end
550 of a malloc() allocated buffer. In rare circumstances this could
551 lead to some of the source image not being written to the target
552 image, or possibly to a segmentation fault.
553 I don't believe this has any security concerns beyond that.
554
0d052fd9
TC
555 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
556 text drawn would be nonsense. This would also read beyond the end
557 of a malloced buffer.
558
13671b17
TC
559 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
560 truncated early.

606 SampleFormat is ignored for paletted images.
607
237d9e03
TC
608 Mixed SampleFormat are handled incorrectly, since libtiff returns
609 only the first SampleFormat value, and an image with both an alpha
610 channel and SampleFormat = 2 for color channels probably has a
611 different SampleFormat for the alpha channel.

864 matrix to use the distance between the outlier pixels rather than
865 the pixel dimensions (ie. dimension-1).
866 With all of this the output of rotate(degrees => 270) on an 8-bit

900 - when downconverting samples (eg. from floating point to 8 bit)
901 Imager now rounds the sample value rather than attempting to
902 allocate input values over output values equally. The old
903 behaviour had the probably surprising effect of converting a
904 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
905 2.
906 This may result in slightly different 8 or 16-bit output images.

908 - BI_BITFIELD BMP images were handled incorrectly, both in
909 incorrectly calculating the space required for the masks and in
910 processing the image data itself.
911 https://rt.cpan.org/Ticket/Display.html?id=76736
912
913 - some odd width BMP BI_RLE4 images use run lengths that run one off
914 the edge of the image. Imager now allows this, discarding the
915 extra column.

926 - Imager::Probe can now probe for libraries with dependent libraries,
927 common for static linking, eg. libpng requires libz.
928 https://rt.cpan.org/Ticket/Display.html?id=74043
929
930 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

933 handle a statically linked libpng.
934 https://rt.cpan.org/Ticket/Display.html?id=74043
935
936 - if a probe includes testcode, Imager::Probe now checks that code as
937 part of the process of checking each configuration rather than as a
938 post test of the found configuration. This allows alternate
939 configurations to be checked if a matching but non-working
940 configuration is found.

1178 - io_glue I/O buffering re-work:
1179
1180 - reorganize io_glue to do it's own buffering by default
1181
1182 - the unbuffered functions are available as i_io_raw_read() (or
1183 raw_read() from perl) etc but are not recommended for typical
1184 use.
1185
1186 - use the new i_io_peekn() when checking for file magic to avoid
1187 seek, allowing Imager to detect the file type and read the file
1188 from an unseekable stream (for formats that don't use random
1189 access)
1190
1191 - added several new I/O layer API functions.

1196 - TIFF now uses wrapper functions of the correct types to avoid casts
1197 https://rt.cpan.org/Ticket/Display.html?id=69912
1198
1199 - the callback IO object did its own buffering, controlled by the
1200 maxbuffer parameter supplied to the read() and write() methods.
1201 This buffering has been removed, to avoid redundancy with the
1202 common io_glue buffering. This also avoids a bug in that code
1203 which could rarely pass a zero length to the read callback and
1204 then panic about the result.
1205
1206 - the callback IO object now tests the result of calling the close
1207 callback, which should return true for success.
1208
1209 - the PNM reader did its own buffering. This buffering has been
1210 removed to avoid redundancy with the common io_glue buffering.
1211
1212 - previously the read handlers for fd and callback I/O layers would
1213 call the underlying interface (POSIX read or your supplied callback)
1214 until it filled the buffer. It now only makes one call.
1215
1216 - added public constructors for I/O layer objects (see Imager::IO)
1217
1218 - all core file handlers now use the i_io_foo() wrappers to gain
1219 access to buffered I/O rather than calling the I/O layer
1220 callbacks directly.
1221
1222 - all core file handlers now check for error on close.
1223
1224 - Backward compatibility: if you hava custom file handlers, you can
1225 use i_io_write() etc since they're available as macros in older
1226 versions of Imager.
1227
1228 - eliminate the final remnants of io_glue_commit_types().
1229
1230 - bump IMAGER_API_VERSION, since the above may break assumptions.
1231
1232 - removed the long unused i_gen_reader() and i_gen_writer() utility
1233 functions.

1295
1296Development release as a sanity check for the types re-work.
8d14daab
TC
1297
1298Massive types re-work:
1299
1300 - the type used internally for pixel co-ordinates and image sizes is
1301 now 64-bit on 64-bit platforms (at least sane ones).
1302
1303 - size_t is now used consistently for memory block sizes.
1304
1305 - since this changes the binary interface, the Imager API version has
1306 been incremented. Any module that uses the API will need to be
1307 rebuilt. In most cases that will be enough, but calls to any APIs
1308 that take a pointer to image sizes may need source changes.
1309
1310 - you should be able to create very large images on 64-bit systems,
1311 if you have enough memory. Successfully created a 32768 x 49192 x
1312 3 channel image, filled with a tiled image and scaled it. The
1313 unscaled image was also successfully saved to a JPEG.
1314
1315 - check the image size before attempting to write BMP, GIF, JPEG,
1316 PNG, SGI, TGA, TIFF images.
1317
1318 - correctly handle reading TGA images over 32767 pixels wide or tall.
1319
1320Incidental changes:
1321
1322 - the gif_left and gif_top tags are now clamped to non-negative

1979 noalpha channels or back.
1980 https://rt.cpan.org/Ticket/Display.html?id=30908
1981
1982 - rubthrough() now falls back to pasting when the source doesn't have
1983 an alpha channel. This effectively treats the source as having a
1984 max alpha channel, the right thing to do.
1985 http://rt.cpan.org/Ticket/Display.html?id=29944

2036 problem with loading such an image. I haven't been able to find any
2037 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
2038 I'll match it's behaviour. See issue 114913 in the GIMP's

2196 - the mask for ICO/CUR images is now applied as an alpha channel to
2197 the returned image. For the old behaviour, supply ico_masked => 0
2198 to read() or read_multi(). This should be less confusing when
2199 using Imager as a general image processor.

2357Imager 0.55 - 16 Dec 2006
2358===========
2359
2360This is primarily a bug fix release.
2361
2362Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2363
2364There is one new feature:
2365
2366 - the Win32 font driver now supports UTF8 (RT 22166)
2367 http://www.cpanforum.com/threads/3276
2368 http://rt.cpan.org/Ticket/Display.html?id=22166
2369
2370Several bugs were fixed:
2371
2372 - the string() method would not output the string "0"
2373 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2374
2375 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2376 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2377
2378 - the gif_disposal and gif_user_input tags weren't being read from
2379 the file correctly
2380 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2381
2382 - gif.c was failing to build under MSVC
2383 http://rt.cpan.org/Ticket/Display.html?id=23922
2384
2385 - in some cases strings passed to the string() method were treated as
2386 terminated by NUL (chr 0)
2387 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2388
2389 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2390 that's the default build name for zlib on Win32.
2391 http://rt.cpan.org/Ticket/Display.html?id=23064
2392
2393 - search $Config{incpath} for headers too, which we should have been
2394 doing all along.
2395
2396Win32 font driver fixes:
2397
2398 - the global descent value from bounding box was the wrong sign
2399 http://www.cpanforum.com/threads/3276
2400
2401 - if the first or last glyph overflowed the left or right side of the
2402 advance width they would be clipped
2403
2404
2405Imager 0.54 - 14 Sep 2006
2406===========
2407
2408This is primarily a feature release:
2409
2410 - a new qtype value 'mixing' has been added to the scale()
2411 method. This is faster than 'normal', slower than 'preview'. This
2412 is based on the method used by pnmscale, and seems to produce less
2413 blurry results than normal.
2414 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2415
2416 - the rubthrough() method can now render onto images with an alpha
2417 channel.
2418 http://rt.cpan.org/Ticket/Display.html?id=20678
2419
2420 - the read_multi() method now falls back to calling doing a single
2421 image read via the read() method and write_multi() will now fall
2422 back to calling write() if a single image is supplied. This means
2423 you can simply call the read_multi() or write_multi() functions
2424 without having to check if the type is formatted by that method.
2425 http://rt.cpan.org/Ticket/Display.html?id=19457
2426 http://rt.cpan.org/Ticket/Display.html?id=19458
2427
2428 - the GIF loop extension can now be written. If you don't have
2429 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2430 should upgrade.
2431 http://rt.cpan.org/Ticket/Display.html?id=21185
2432
2433 - getscanline() and setscanline() can now read/write palette index
2434 based data from/to the image for paletted images, by setting type to
2435 'index'.
2436 http://rt.cpan.org/Ticket/Display.html?id=20338
2437
2438 - we no longer hassle you to disable GIF support
2439 http://rt.cpan.org/Ticket/Display.html?id=20687
2440
2441 - minor documentation fixes
2442
2443
2444Imager 0.53 - 26 Jul 2006
2445===========
2446
2447This is a bugfix release.
2448
2449Some test code was left in a code path not covered by the test
2450suite. A test was added to cover this code path and the test code was
2451removed.

2454
2455Imager 0.52 - 25 Jul 2006
2456===========
2457
2458This is primarily a feature release, but contains a fair few bug
2459fixes, new features:
2460
2461 - ability to read and write MS Windows ICO and CUR files
2462
2463 - you can now add file format plugins to support new file formats
2464
2465 - add POD coverage tests
2466
2467 - setcolors() and addcolors() now accept color names and so on
2468 instead of requiring Imager::Color objects.
2469 http://rt.cpan.org/Ticket/Display.html?id=20056
2470
2471 - flood_fill() can now fill to a specified border color instead of
2472 just to the area the same color as the seed.
2473 http://rt.cpan.org/Ticket/Display.html?id=19618
2474
2475
2476Bug fixes:
2477
2478 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2479 calculating the advance width.
2480 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2481
2482 - bounding_box for the T1 driver wasn't including leading and
2483 trailing spaces in the bounding box as the other drivers did, it also
2484 produced strange results for empty strings or strings containing only
2485 spaces
2486
2487 - when reading CMYK jpeg images they were being transferred to the
2488 image object as is, producing a four channel image. It only looked ok
2489 due to an old still unfixed Photoshop bug. We now convert from the
2490 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2491 http://rt.cpan.org/Ticket/Display.html?id=20416
2492
2493 - reading a CYMK TIFF would result in a 4 channel image, reading any
2494 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2495 result in an error.
2496 http://rt.cpan.org/Ticket/Display.html?id=20415
2497
2498 - added /usr/local/include to the default include search path, since
2499 we were already searching /usr/local/lib for libraries.
2500
2501And various minor fixes and documentation updates.
2502
2503
2504Imager 0.51 - 23 Apr 2006
