3Imager 1.012 - 14 Jun 2020
4============
5
6 - Imager has moved to github.
c443788c
TC
7
8 - T1lib support is deprecated
9
10 - added guassian2 filter which allows separate filter radii for vertical
11 and horizontal. Thanks to Leolo.
12 https://rt.cpan.org/Ticket/Display.html?id=129769
13
14 - freetype2 support can now use pkg-config to configure itself.
15
480d238c
TC
16 - added red, green, blue, alpha methods to color objects.
17
18 - eliminate use vars.

20Imager 1.011 - 7 Mar 2019
21============
22
7e5c22f6
TC
23General changes:
24
25 - correct the type of the data parameter for im_decode_exif().
26
27 - fix the release date listed below for 1.010
28
29 - add missing change entry for RT #128142
30
e2f7e242
TC
31 - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
32 failures on one CPAN smoker.
33
34 - add the mymeta check (AUTHOR testing only) to MANIFEST
35
36More Coverity fixes:
37
38 - translate_errdiff() could leak memory on failure (introduced in
39 1.009) CID 185565.
40
41 - i_img_make_palette() could leak memory on failure (introduced in
42 1.009) CID 185566.
43
44 - DSO_open(), from the original dynamic loading API, could leak
45 dlopen() handles on failure. CID 185309. DSO_close() now releases
46 the memory associated with the internal DSO handle, rather than
47 only releasing the dlopen() handle.

5497656d
TC
50============
51
52General changes:
53
54 - added the add_file_magic() class method for adding magic for new
55 file types to Imager's fairly primitive file magic detection.
56
57 - fixed an embarassing documentation typo in Imager::Test.
58
59 - trying to read from a GIF file with no images now sets an error
60 message. Thanks to Peter Sergeant for reporting this.
61 https://rt.cpan.org/Ticket/Display.html?id=128481
62
4321405f
TC
63 - use undeprecated encoding symbols for FT2. This should fix the
64 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
65 Rezic for the report.
66 https://rt.cpan.org/Ticket/Display.html?id=128142
67
5497656d
TC
68Coverity has come back up read-only, a few more changes:
69
70 - add missing va_end() for bmp.c's write_packed(). CID 185320.
71
72 - similarly for read_packed(). CID 185329.
73
74 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
75 complained about a missing return, Coverity complains about the
76 return. CID 185325.
77
78 - avoid a possible sign extension in imsgi.c. CID 185326.
79
80 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
81 deliberately fall through switch cases. CID 185328.
82
83 - add assertions in callers to i_new_hatch_low() since Coverity
84 complained about some possible inconsistent NULL checks. CID
85 185339. I ended up rearranging this function later.
86
87 - remove pointless NULL checks from i_flipxy() and i_img_destroy().
88

57cc9afe
TC
91============
92
1456b645
TC
93Critical issue:
94
95 - drawing a filled, anti-aliased circle to the left or right of the
96 image (not within the image at all) would cause a buffer overflow.
97 https://rt.cpan.org/Ticket/Display.html?id=128208
98
a3b721bb
TC
99General changes:
100
101 - to_paletted() and make_palette() now fail (with an error in
102 errstr()) if invalid quantization parameters are supplied.
103
35ec3a87
TC
104 - map() would corrupt a channel if there was a gap in the arrayref of
105 channels. Detected by Coverity. CID 185300.
106
5824f4c2
TC
107 - most numeric parameters to the XS implementation now throw an
108 exception if supplied an unoverloaded reference.
109 https://rt.cpan.org/Ticket/Display.html?id=128208
110
e32d3a7c
TC
111Coverity finally finished a build[1], fixed several of the problems
112found. Coverity went down before I could finish working through them.
1791cbdb 113
8445279e
TC
114High severity:
115
1791cbdb 116 - reading a color-mapped TGA file with an id string would cause a
8445279e 117 double-free if the palette was truncated. CID 185317.
1791cbdb 118
6494c395
TC
119 - mixing scaling to sizes where the accumulator row, the working
120 output row or the working input row didn't fit into the address
121 space could result in memory leaks. This can probably only be
8445279e 122 reproduced on very wide floating-point sample images. CID 185318.
6494c395 123
fc24ca5f 124 - convert an array style function parameter pointer to pointer style
3d7b055c 125 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 126 CID 185343.
3d7b055c 127
8445279e 128 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 129
20c297d4 130 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 131 implementation. CID 185303.
20c297d4 132
fc24ca5f 133 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 134 drawing (it should always end up being set.) CID 185341.
fc24ca5f 135
f7675b46 136 - addi style makemap could potentially read one past the end of an
8445279e 137 array. CID 185337.
f7675b46 138
58ec1fde
TC
139 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
140 would result in read beyond the end of the built-in hatch array.
141 Negative values (which Coverity didn't complain about) could also
8445279e 142 cause problems. CID 185331.
58ec1fde 143
b7346865
TC
144 - the Imager::Color set_internal() interal method no longer
145 calls the over-complicated ICL_set_internal() (which is retained
146 only for the old API.) Coverity complained that this leaked, but
147 this could only occur with an invalid (NULL pointer) color object.
8445279e 148 CID 185323.
b7346865 149
785364c1
TC
150 - the underlying implementation of the map() method could read before
151 the beginning on an allocated array if supplied with inconsistent
152 parameters, which Coverity complained about. No Imager code calls
153 that function with inconsistent parameters, but a
8445279e 154 belt-and-suspenders check was added. CID 185315.
785364c1 155
eb7e48c9
TC
156 - Coverity complained a call to i_getcolors(), used by the
157 implementation of the is_bilevel() method could leave the fetched
8445279e 158 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 159
c1c8b1e9
TC
160 - a numeric combining mode of 13 (eg. as a parameter to
161 Imager::Fill->new())could cause an invalid array read in
162 i_get_combine() due to a fencepost error in validating the combine
8445279e 163 number. CID 185299.
c1c8b1e9 164
59fd0c6b 165Lower severity (according to Coverity):
c4fd43be
TC
166
167 - avoid an unneeded EXTEND() call when the FT1 has_chars()
168 implementation returns 0. CID 185350.
169
170 - avoid accessing a possibly NULL map from MakeMapObject() in a
171 logging call. (GIF) CID 185296.
172
4615ad8d
TC
173 - gradgen() allocated the wrong amount of space (always too much) for
174 the color array. CID 185291.
175
ea3099db
TC
176 - avoid dead code in i_tt_glyph_names(). CID 185321.
177
8b810590
TC
178 - avoid dead code in i_get_anonymous_color_histo(), which is the
179 implementation of getcolorusage(). CID 185327.
180
4eb9a521
TC
181 - avoid dead code in i_ft2_glyph_name(), which is the implementation
182 of glyph_names() for FT2. CID 185342.
183
c028aa12
TC
184 - avoid dead code in i_t1_glyph_names(), which is the implementation
185 of glyph_names() for T1. CID 185322.
186
e7772cea
TC
187 - avoid an unneeded EXTEND() call when the FT2 has_chars()
188 implementation returns 0. CID 185292.
189
596f3eee
TC
190 - the unpack code for ICO/CUR file handling could extend 32-bit
191 unsigned values to 64-bit signed. I believe this is harmless. CID
192 185319.
193
a2ca2b80
TC
194 - remove an unneeded check when terminating the stream for JPEG
195 writing. CID 185347.
196
56ce7446
TC
197 - skip an unneeded check when freeing the combine temp buffer in the
198 fountain filter. CID 185286.
199
200 - check the combine function pointer consistently rather than the
201 combine code in one place in the fountain filter.
202
a3b721bb
TC
203 - error diffusion now validates a custom error diffusion map and reports
204 an error if it's bad. CID 185288.
205
215d9ead
TC
206 - avoid discarding the value of i_io_getc() when scanning numbers in
207 pnm.c. CID 185293.
208
9ca939d0
TC
209 - handle failure to clone the log filehandle when cloning the Imager
210 context object on thread creation. CID 185294.
211
70501294 212 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
213 glyph index with a NULL character map when calculating the glyph
214 for display for FT1. This should be rare. CID 185297.
215
216 - fix a similar bug when calculating whether a glyph is present for
217 has_chars() for FT1. CID 185302.
70501294 218
6fa51f9c
TC
219 - i_img_info() (C API) no longer tries to handle a NULL image object
220 pointer. CID 185298.
221
a2c2d400
TC
222 - re-work testing for size_t overflow for circle/random
223 super-sampling for fountain fills. CID 185304.
224
8e2e2347
TC
225 - don't check if the unsigned size passed to Imager's malloc wrapper
226 (mymalloc) is negative. Left from when that parameter was signed.
227 CID 185305.
228
0c16f204
TC
229 - make some types larger and add a cast to prevent integer overflows
230 when calculating a palette with median cut for extraordinarily
231 large images. CID 185306.
232
748bfdfc
TC
233 - don't check if the unsigned size supplied to
234 im_set_image_file_limits() is negative. CID 185307.
235
57cc9afe 236[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
237build queue, and seemed to have been cancelled by Coverity. A build
238submitted on NYE went through in minutes.

TC
240Imager 1.008 - 31 Dec 2018
241============
242
75e155e1 243 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
244 This allows file formats that store EXIF data as blobs similarly
245 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 246
b5bbf161 247 - added some more file extensions to image file type mappings
75e155e1
TC
248
249 - added add_type_extensions() class method
250
f38e738a
TC
251 - Imager::Files now links to Imager::Install when discussing
252 appropriate libraries.

TC
256============
257
a9fa5463
TC
258 - add png_compression_level tag for writing PNG files.
259
260 - avoid flooring a second time in matrix transform interpolation.
261 https://rt.cpan.org/Ticket/Display.html?id=124001
262
434c2338
TC
263 - produce v2 metadata.
264 Includes change from the ticket and updates to sub-modules.
265 https://rt.cpan.org/Ticket/Display.html?id=127216
266
d1d8320e
TC
267 - improve error reporting for the polygon() method
268
ac3e79fb
TC
269Imager 1.006 - 26 Aug 2017
270============
271
ba7ddbae
TC
272 - the internal i_errors() function now correctly allocates the stack
273 space needed for its result.
274 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
275
276 - t/100-base/020-color.t now uses Imager::Test's test functions
277 instead of its own.
278 https://rt.cpan.org/Ticket/Display.html?id=111993
279
344dda51
TC
280 - write_multi() now returns an error result (a false value) if called
281 with a non-(Imager image object). Previously it would typically
282 crash.
283 https://rt.cpan.org/Ticket/Display.html?id=117878
284
285 - improve the documentation of the jpegquality parameter when
286 writing JPEG files.
287
288 - add code to mitigate CVE-2016-1238, Imager will no longer search the
289 default current directory entry in @INC when searching for file
290 format support modules.

292Imager 1.005 - 16 Apr 2016
293============
294
295It's now been ten years since I switched to the new Changes file in
296release 0.55.
297
cd0109d8
TC
298 - revert the ivdformat probes, they don't work as is and trying to
299 fix them is too much work for now.
300
6f1cbfed
TC
301Imager 1.004_004 - 15 Apr 2016
302================
303
9c45cc49
TC
304 - test that the ivdformat from Config is correct and look for a valid
305 one if it isn't.
306 For the strange Win32 failures.
307
308 - fix a copy and paste error in pod in samples/samp-form.cgi
309

TC
310Imager 1.004_003 - 23 Mar 2016
311================
312
bd2d657d
TC
313 - add some extra error reporting to the I/O layers tests, this might
314 help catch a failure seen on Win32.

TC
317Imager 1.004_002 - 20 Mar 2016
318================
319
735b3e7b
TC
320 - don't use the seek() method on opened() handles in
321 t/200-file/400-basic.t. In older versions of perl such handles are
322 only IO::Handle objects, not IO::File, and don't have a seek()
323 method.

TC
325Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
326================
327
08914ed1
TC
328 - re-work the t/200-file/400-basic.t to correctly handle failures
329 It's custom ok() function didn't have a prototype and didn't use scalar().
330 This caused ok() to use the note instead of the value being tested when
331 the method called returned an empty list. For an example of the problem
e6226ce5 332 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 333
a2791e47
TC
334 - remove some noise from when Imager tried to work with bugs in old
335 versions of giflib. I can't do much about the new bugs.
08914ed1 336
e6226ce5
TC
337 - the new autolevels filter (Imager 0.99) used an integer for the
338 sample scaling factor which caused the top output level to be too
339 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
340 https://rt.cpan.org/Ticket/Display.html?id=111871
341
e6226ce5 342 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
343 minimum and maximum luminance from the histogram. This slightly
344 reduced the contrast of the output image.
345 https://rt.cpan.org/Ticket/Display.html?id=111871
346
347 - the new autolevels filter now uses a lookup table for 8-bit images
348 to avoid a floating point multiply for each sample.
349 https://rt.cpan.org/Ticket/Display.html?id=111871
350
e6226ce5
TC
351 - fixed several memory leaks detected by valgrind:
352
353 - addcolors() leaked the temporary array of colors supplied to the
354 internal API
355
356 - make_palette() leaked the temporary image array (not the images
357 themselves) passed to the internal API.
358
359 - combine()/i_combine() leaked its working row buffers
360
361 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
362 buffer if there were too many colors
363
364 - getcolorcount()/i_count_colors() leaked the sample buffer if
365 there were too many colors.
366
367 - the nearest_color filter (undocumented until I find a use for it)
368 leaked both temporaries passed to the API and internal buffers
369
a2791e47
TC
370 - the internal process of upgrading a paletted image to a direct
371 color image would leak a context object reference count.
372
373 - a write failure when writing to a GIF file could leak memory.
374
375 - failing to write to a 1-bit/pixel ICO image could leak memory.
376
377 - Imager no longer deliberately leaks the context object from the
378 initial thread. This was done to ensure there was always a context
379 object available, but the code that needed that now handles the
380 lack correctly,
381
e6226ce5
TC
382 - fixed some uninitialized memory usage detected by valgrind:
383
384 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
385 i_matrix_transform_bg() didn't initialize a working color value
386 if there was zero pixel coverage.
387
388 - i_ft2_cp() didn't initialize the complete color when producing an
389 intermediate image. This caused uninitialized value usage when
390 logging the color.

TC
392Imager 1.004 - 8 Nov 2015
393============
394
5ebfb369
TC
395 - Imager::Color::Table is now pre-loaded by the preload() method.
396 https://rt.cpan.org/Ticket/Display.html?id=104896
397
398 - fix an assertion triggered under perl 5.23.4.
399 Thanks to A. Sinan Unur for the report and the patch.
400
7b638aba
TC
401 - Imager->new can now be used to read raw image files.
402 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 403 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
404
405 - deal with output changes from Pod::Spell

0d1baac8
TC
408Imager 1.003 - 12 May 2015
409============
410
0fda3cfd
TC
411 - update 1.002 release notes to include the center change for filled
412 circle drawing.
413
414 - flood_fill() would escape beyond a 4-connected space under some
415 circumstances.
416 Added many more flood_fill() tests.

TC
419Imager 1.002 - 3 Apr 2015
420============
421
334b8922
TC
422 - drawing anti-aliased filled circles is now 10 to 50 times faster
423 depending on the size of the circle.
0fda3cfd
TC
424 This also changed the center from being the center of the pixel to
425 being the top left of the pixel to match the filled arcs drawn by
426 arc().
334b8922
TC
427 https://rt.cpan.org/Ticket/Display.html?id=101682
428
429 - enhancements to polygon filling:
430
431 - added a mode parameter to control how overlapping regions behave
432
433 - added a polypolygon() method to fill more than one polygon at a
434 time
435
436 - polygon filling is now exposed through the API.
437
45c8e262
TC
438 - added colormodel(), alphachannel() and colorchannels() methods.
439 These were added for two reasons:
440
441 - a future version of Imager may allow the number of channels in
442 an image to not directly represent the color model of an image.
443 eg. a greyscale TIFF image with multiple alpha channels.
444
445 - a future version of Imager may allow an image to be read without

d96c4de8 448 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
449 the value back.
450
451 An untranslated image would be unusable as image data, so
452 colormodel() would return "unknown" in this case.
453
454 Similarly a CMYK image might be returned as an "unknown" color
455 model image, if the caller chooses to disable translation to
456 RGB.

562 - Imager::File::PNG now supports libpng 1.6.10.
563 1.6.10 changed CRC errors from benign errors to normal errors,
564 which broke the test which used CRC errors to check for benign
565 error support. Switched to using a 1-bit grey-scale image with a
566 palette to test for benign errors.

570===========
571
f84f86a2
TC
572Incompatible changes:
573
574 - the return value of setpixel() has changed.
575
576 Previously the return values for undrawable pixels vs caller errors
577 changed depending on whether you used the multiple pixel calling
578 mechanism, or the single pixel mechanism.
579
580 Now:
581
582 - for an invalid parameter, such as an unknown colour, or missing
583 parameter, an empty list (or undef in scalar context) is
584 returned, and errstr() is set,
585
586 - otherwise the number of pixels drawn is returned. If none of
587 the pixels could be drawn (they were all outside the image), "0
588 but true" is returned.
589
590 https://rt.cpan.org/Ticket/Display.html?id=87650
591
592Other changes:
593
6ba09ab9
TC
594 - when drawing on an image with an alpha channel where the source
595 minimum is greater than zero, Imager would read from beyond the end
596 of a malloc() allocated buffer. In rare circumstances this could
597 lead to some of the source image not being written to the target
598 image, or possibly to a segmentation fault.
599 I don't believe this has any security concerns beyond that.
600
0d052fd9
TC
601 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
602 text drawn would be nonsense. This would also read beyond the end
603 of a malloced buffer.
604
13671b17
TC
605 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
606 truncated early.

651
652 SampleFormat is ignored for paletted images.
653
237d9e03
TC
654 Mixed SampleFormat are handled incorrectly, since libtiff returns
655 only the first SampleFormat value, and an image with both an alpha
656 channel and SampleFormat = 2 for color channels probably has a
657 different SampleFormat for the alpha channel.

906 - The size of rotated images is no longer rounded up so aggressively.
907 Added rounding to the linear interpolation done for rotate() and
908 matrix_transform() for 1 and 3 channel 8-bit images.
909 Adjusted the two tranlate matrices used to build the final rotation
910 matrix to use the distance between the outlier pixels rather than
911 the pixel dimensions (ie. dimension-1).
912 With all of this the output of rotate(degrees => 270) on an 8-bit
913 image exactly matches the output of rotate(right => 270).

921 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
922 the API level compiled into a loadable module such as
923 Imager::File::GIF doesn't match that of Imager. Previously it
924 could be difficult to determine exactly which module was failing to

946 - when downconverting samples (eg. from floating point to 8 bit)
947 Imager now rounds the sample value rather than attempting to
948 allocate input values over output values equally. The old
949 behaviour had the probably surprising effect of converting a
950 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
951 2.
952 This may result in slightly different 8 or 16-bit output images.

1224 - io_glue I/O buffering re-work:
1225
1226 - reorganize io_glue to do it's own buffering by default
1227
1228 - the unbuffered functions are available as i_io_raw_read() (or

1230 use.
1231
1232 - use the new i_io_peekn() when checking for file magic to avoid
1233 seek, allowing Imager to detect the file type and read the file
1234 from an unseekable stream (for formats that don't use random
1235 access)

1245 - the callback IO object did its own buffering, controlled by the
1246 maxbuffer parameter supplied to the read() and write() methods.
1247 This buffering has been removed, to avoid redundancy with the
1248 common io_glue buffering. This also avoids a bug in that code
1249 which could rarely pass a zero length to the read callback and
1250 then panic about the result.
1251
1252 - the callback IO object now tests the result of calling the close
1253 callback, which should return true for success.
1254
1255 - the PNM reader did its own buffering. This buffering has been
1256 removed to avoid redundancy with the common io_glue buffering.
1257
1258 - previously the read handlers for fd and callback I/O layers would
1259 call the underlying interface (POSIX read or your supplied callback)
1260 until it filled the buffer. It now only makes one call.
1261
1262 - added public constructors for I/O layer objects (see Imager::IO)
1263
1264 - all core file handlers now use the i_io_foo() wrappers to gain
1265 access to buffered I/O rather than calling the I/O layer
1266 callbacks directly.
1267
1268 - all core file handlers now check for error on close.
1269
1270 - Backward compatibility: if you hava custom file handlers, you can
1271 use i_io_write() etc since they're available as macros in older
1272 versions of Imager.
1273
1274 - eliminate the final remnants of io_glue_commit_types().
1275
1276 - bump IMAGER_API_VERSION, since the above may break assumptions.

1339Imager 0.84_01 - 8 Aug 2011
1340==============
1341
1342Development release as a sanity check for the types re-work.
8d14daab
TC
1343
1344Massive types re-work:
1345
1346 - the type used internally for pixel co-ordinates and image sizes is
1347 now 64-bit on 64-bit platforms (at least sane ones).
1348
1349 - size_t is now used consistently for memory block sizes.
1350
1351 - since this changes the binary interface, the Imager API version has
1352 been incremented. Any module that uses the API will need to be
1353 rebuilt. In most cases that will be enough, but calls to any APIs
1354 that take a pointer to image sizes may need source changes.
1355
1356 - you should be able to create very large images on 64-bit systems,
1357 if you have enough memory. Successfully created a 32768 x 49192 x
1358 3 channel image, filled with a tiled image and scaled it. The
1359 unscaled image was also successfully saved to a JPEG.
1360
1361 - check the image size before attempting to write BMP, GIF, JPEG,
1362 PNG, SGI, TGA, TIFF images.
1363
1364 - correctly handle reading TGA images over 32767 pixels wide or tall.
1365
1366Incidental changes:
1367
1368 - the gif_left and gif_top tags are now clamped to non-negative
1369 values when writing a GIF image.
1370
1371 - removed dead callback read/write code
1372
1373The default maximum memory size when reading files is now 1G.

2403Imager 0.55 - 16 Dec 2006
2404===========
2405
2406This is primarily a bug fix release.
2407
2408Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2409
2410There is one new feature:
2411
2412 - the Win32 font driver now supports UTF8 (RT 22166)
2413 http://www.cpanforum.com/threads/3276
2414 http://rt.cpan.org/Ticket/Display.html?id=22166
2415
2416Several bugs were fixed:
2417
2418 - the string() method would not output the string "0"
2419 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2420
2421 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2422 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2423
2424 - the gif_disposal and gif_user_input tags weren't being read from
2425 the file correctly
2426 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2427
2428 - gif.c was failing to build under MSVC
2429 http://rt.cpan.org/Ticket/Display.html?id=23922
2430
2431 - in some cases strings passed to the string() method were treated as
2432 terminated by NUL (chr 0)
2433 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2434
2435 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2436 that's the default build name for zlib on Win32.
2437 http://rt.cpan.org/Ticket/Display.html?id=23064
2438
2439 - search $Config{incpath} for headers too, which we should have been
2440 doing all along.
2441
2442Win32 font driver fixes:
2443
2444 - the global descent value from bounding box was the wrong sign
2445 http://www.cpanforum.com/threads/3276
2446
2447 - if the first or last glyph overflowed the left or right side of the
2448 advance width they would be clipped
2449
2450
2451Imager 0.54 - 14 Sep 2006
2452===========
2453
2454This is primarily a feature release:
2455
2456 - a new qtype value 'mixing' has been added to the scale()
2457 method. This is faster than 'normal', slower than 'preview'. This
2458 is based on the method used by pnmscale, and seems to produce less
2459 blurry results than normal.
2460 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2461
2462 - the rubthrough() method can now render onto images with an alpha
2463 channel.
2464 http://rt.cpan.org/Ticket/Display.html?id=20678
2465
2466 - the read_multi() method now falls back to calling doing a single
2467 image read via the read() method and write_multi() will now fall
2468 back to calling write() if a single image is supplied. This means
2469 you can simply call the read_multi() or write_multi() functions
2470 without having to check if the type is formatted by that method.
2471 http://rt.cpan.org/Ticket/Display.html?id=19457
2472 http://rt.cpan.org/Ticket/Display.html?id=19458
2473
2474 - the GIF loop extension can now be written. If you don't have
2475 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2476 should upgrade.
2477 http://rt.cpan.org/Ticket/Display.html?id=21185
2478
2479 - getscanline() and setscanline() can now read/write palette index
2480 based data from/to the image for paletted images, by setting type to
2481 'index'.
2482 http://rt.cpan.org/Ticket/Display.html?id=20338
2483
2484 - we no longer hassle you to disable GIF support
2485 http://rt.cpan.org/Ticket/Display.html?id=20687
2486
2487 - minor documentation fixes
2488
2489
2490Imager 0.53 - 26 Jul 2006
2491===========
2492
2493This is a bugfix release.
2494
2495Some test code was left in a code path not covered by the test
2496suite. A test was added to cover this code path and the test code was
2497removed.

2501Imager 0.52 - 25 Jul 2006
2502===========
2503
2504This is primarily a feature release, but contains a fair few bug
2505fixes, new features:
2506
2507 - ability to read and write MS Windows ICO and CUR files
2508
2509 - you can now add file format plugins to support new file formats
2510
2511 - add POD coverage tests
2512
2513 - setcolors() and addcolors() now accept color names and so on
2514 instead of requiring Imager::Color objects.
2515 http://rt.cpan.org/Ticket/Display.html?id=20056
2516
2517 - flood_fill() can now fill to a specified border color instead of
2518 just to the area the same color as the seed.
2519 http://rt.cpan.org/Ticket/Display.html?id=19618
2520
2521
2522Bug fixes:
2523
2524 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2525 calculating the advance width.
2526 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2527
2528 - bounding_box for the T1 driver wasn't including leading and
2529 trailing spaces in the bounding box as the other drivers did, it also
2530 produced strange results for empty strings or strings containing only
2531 spaces
2532
2533 - when reading CMYK jpeg images they were being transferred to the
2534 image object as is, producing a four channel image. It only looked ok
2535 due to an old still unfixed Photoshop bug. We now convert from the
2536 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2537 http://rt.cpan.org/Ticket/Display.html?id=20416
2538
2539 - reading a CYMK TIFF would result in a 4 channel image, reading any
2540 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2541 result in an error.
2542 http://rt.cpan.org/Ticket/Display.html?id=20415
2543
2544 - added /usr/local/include to the default include search path, since
2545 we were already searching /usr/local/lib for libraries.
2546
2547And various minor fixes and documentation updates.
2548
2549
2550Imager 0.51 - 23 Apr 2006
