4===========
5
0a2956ab
TC
6 - handle the SVf_UTF8 flag correctly on magic strings passed to
7 Imager::IO's write() and raw_write() methods.
8 This may misbehave in perl 5.6.x since the UTF8 flag may not be
9 visible in the main SV after SvGETMAGIC().
10 https://rt.cpan.org/Ticket/Display.html?id=83438
11
12 - document that bounding_box() ignores the transformation matrix
13 supplied to tranform() for fonts.

17==============
18
1540d1d4
TC
19 - enable debug logging for the standard font tests
20
21 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
22 due to a bug in that version of perl.
23
24 - don't test for read() failing on a write-only handle in 5.8.x and
25 earlier, this was fixed in change 862083f7e4 in perl.
26
27 - report the version of Inline found during testing (an attempt to
28 diagnose some intermittent failures.)

31==============
32
14a4ea18 33 - NOTE: possibly backward incompatible:
3dcf7595
TC
34 support reading from/writing to perl filehandes that aren't raw
35 files.
36
37 This allows Imager's I/O to honour handles with layers such as
38 gzip, scalar file handles or tied file handles.
39
14a4ea18 40 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
41 use fileno() to retrieve the fd for the file and call write(2) etc
42 on it directly.

43 https://rt.cpan.org/Ticket/Display.html?id=78843
44
45 - moved most of README to lib/Imager/Install.pod which should make it
46 more accessible to the "web" generation, also significantly updated
47 and re-worked it.

65 - drawing text to a channel with FT2 would draw with random coverage
66 due to an uninitialized alpha channel.
67

TC
113Imager 0.93 - 15 Oct 2012
114===========
115
116Bug fixes:
71fbe41a
TC
117
118 - previously a transparency enabled GIF write (the default) would
119 always use a GIF89a header even if none of the images were
120 transparent.
7a5f7bc6 121
b2f967ef
TC
122 - previously the probe step for freetype-config would fail on cygwin
123
b2f967ef
TC
124 - catch an invalid matrix parameter to convert() instead of crashing
125 https://rt.cpan.org/Ticket/Display.html?id=79922
126
127 - remove the 16-bit/sample limitation from the documentation for
128 setsamples(), it hasn't applied for many releases.
129 https://rt.cpan.org/Ticket/Display.html?id=79989
130
9673d97e
TC
131 - don't copy setsamples() data parameter, it may be a large scalar

136
8c323994
TC
137 - pass the --verbose command-line option through to Imager::Probe in
138 sub-module's Makefile.PLs

140
e9daa5af
TC
141Enhancements:
142
143 - support for giflib 5.0. (5.0.1 and later)
144 https://rt.cpan.org/Ticket/Display.html?id=79029
145 The giflib API Imager uses doesn't have a mechanism to set the
146 header version in 5.0.0.
147
148 - update the GIF library probe code to check for the new giflib 5.0.1
149 EGifSetGifVersion() function, and to check for the giflib 4.2.0
150 uninitialized gif89 bug.
151 https://rt.cpan.org/Ticket/Display.html?id=79679
152 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
153
154 - avoid static variables when capturing IPTC data from JPEG files
155
156 - match Imager::Font;:T1's error message translations to those from
157 later versions of T1Lib.
158
159 - for libtiff versions that support extended warning handlers (3.8.0
160 or later), use them to avoid some global variables.
161
162 - note Image::ExifTool for better metadata support.
163 https://rt.cpan.org/Ticket/Display.html?id=79251

TC
165Imager 0.92 - 14 Aug 2012
166===========
167
b1c75496
TC
168 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
169 correctly for both probing and runtime.
170 https://rt.cpan.org/Ticket/Display.html?id=77672
171
dcc10c4e
TC
172 - allow building JPEG/imexif.c on C89 compilers.
173
272fcca5
TC
174 - allow building GIF/imgif.c on C89 compilers.

176Imager 0.91 - 4 Jun 2012
177===========
178
ef84bb32 179Bug fixes:
38742a13 180
289d65f4
TC
181 - The size of rotated images is no longer rounded up so aggressively.
182 Added rounding to the linear interpolation done for rotate() and
183 matrix_transform() for 1 and 3 channel 8-bit images.
184 Adjusted the two tranlate matrices used to build the final rotation
185 matrix to use the distance between the outlier pixels rather than
186 the pixel dimensions (ie. dimension-1).
187 With all of this the output of rotate(degrees => 270) on an 8-bit
188 image exactly matches the output of rotate(right => 270).
189 https://rt.cpan.org/Ticket/Display.html?id=77063
190
ef84bb32
TC
191Other changes:
192
193 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
194 internals, those names only matter for the XS interface.
195
196 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
197 the API level compiled into a loadable module such as
198 Imager::File::GIF doesn't match that of Imager. Previously it
199 could be difficult to determine exactly which module was failing to
200 load.
201 https://rt.cpan.org/Ticket/Display.html?id=77173
202
203 - added Imager->check_file_limits() as an interface to the
204 i_int_check_image_file_limits() API.
205
206 - Imager->set_file_limits(reset => 1) now resets the limits to the
207 defaults rather than setting them all to unlimited.
208
209 - wrote a brief security note as Imager::Security
210 https://rt.cpan.org/Ticket/Display.html?id=68910
211
6f31dd14 212Imager 0.90 - 30 Apr 2012
7c4464f5
TC
213===========
214
215Bug fixes:
216
217 - Imager::Test::is_imaged() attempted to process an "epsilon"
218 parameter but the prototype didn't allow for the extra parameter.
219 Corrected the prototype.
220
29b38678
TC
221 - when downconverting samples (eg. from floating point to 8 bit)
222 Imager now rounds the sample value rather than attempting to
223 allocate input values over output values equally. The old
224 behaviour had the probably surprising effect of converting a
225 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
226 2.
227 This may result in slightly different 8 or 16-bit output images.
228
e2a86bac
TC
229 - BI_BITFIELD BMP images were handled incorrectly, both in
230 incorrectly calculating the space required for the masks and in
231 processing the image data itself.
232 https://rt.cpan.org/Ticket/Display.html?id=76736
233
234 - some odd width BMP BI_RLE4 images use run lengths that run one off
235 the edge of the image. Imager now allows this, discarding the
236 extra column.
237
238 - odd length RLE4 runs in BMP images were decoded incorrectly.
239
82eb0687
TC
240 - pkg-config could sometimes return a library that was in a directory
241 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
242 If no -L is included in the pkg-config library information check if
243 EU::MM can find the library, and if not, search our configured
244 directories and insert that into the library flags.
245 https://rt.cpan.org/Ticket/Display.html?id=75869
246
de50f459
TC
247 - Imager::Probe can now probe for libraries with dependent libraries,
248 common for static linking, eg. libpng requires libz.
249 https://rt.cpan.org/Ticket/Display.html?id=74043
250
251 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
252
253 - added alternative probe configurations that try to link libz, to
254 handle a statically linked libpng.
255 https://rt.cpan.org/Ticket/Display.html?id=74043
256
257 - if a probe includes testcode, Imager::Probe now checks that code as
258 part of the process of checking each configuration rather than as a
259 post test of the found configuration. This allows alternate
260 configurations to be checked if a matching but non-working
261 configuration is found.
262 https://rt.cpan.org/Ticket/Display.html?id=74043
263
9d5ff8a6
TC
264Other changes:
265
266 - when reading or writing images via callbacks, the default callbacks
267 now push an error message indicating that a required callback was
268 called but not supplied.
269 https://rt.cpan.org/Ticket/Display.html?id=76782
270
271 - clarify which callbacks are required for reading and writing TIFF
272 images.
273
274 - improve logging for creation of callback I/O layers.
275
de50f459
TC
276 - a little more documentation for Imager::Probe.
277
594f5933
TC
278 - the i_get_file_background() and i_get_file_backgroundf() APIs now
279 return int to indicate whether the i_background tag was found.
280
1b46057d
TC
281 - PNG rework
282 - improve error reporting
283 - add png_interlace, png_bits tags
284 - read paletted images as paletted images, including transparency
285 - read 1 bit greyscale images as a type suitable for other file
286 handlers to write as bilevel
287 - read 16 bit/sample PNG as 16-bit/sample Imager images
288 - write "bilevel" paletted images as 1 bit grayscale images
289 - write paletted images as paletted images
290 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
291 images
292 - improved metadata support

295Imager 0.89 - 18 Mar 2012
296===========
297
298Bug fixes:
299
93eab01e
TC
300 - getpixel(..., type => "float") and the API i_gpixf() have been
301 broken on paletted images since they were implemented.

303
2c1ffb77
TC
304Other changes:

TC
306 - links in the METHOD INDEX now point at the method documentation
307 rather than the heading you can find them under.
308 https://rt.cpan.org/Ticket/Display.html?id=71495
309
a5919365
TC
310 - Imager (and the bundled dynamic modules) no longer fallback to
311 using DynaLoader if loading via XSLoader fails.
312 For the bundled modules this could hide useful error messages.
313 https://rt.cpan.org/Ticket/Display.html?id=75560
314
335078fc
TC
315 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
316 buffer in the array of allocations, but just stores the filename
317 pointer and line number.

320Imager 0.88 - 22 Feb 2012
321===========
322
43bef43b
TC
323 - describe how to build libgif etc on OS X in such a way as to be
324 compatible with a fat binary perl (such as the system perl), in
325 README.
326 https://rt.cpan.org/Ticket/Display.html?id=73371
327

331 - add some other imaging modules to SEE ALSO
332 https://rt.cpan.org/Ticket/Display.html?id=73906
333
3b7f10da
TC
334 - note that the generator of the apparently non-DFSG-free postscript
335 in MMOne.pfb is a Debian package.
336
02323e69
TC
337 - setsamples() is now a true complement to getsamples() - it can
338 write 8-bit or floating point samples from a scalar or array
339 reference. This adds i_psamp() and i_psampf() to the C level API.
340
341 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
342 changed to make better use of the typemap, but these aren't part of
343 the perl level API anyway. There were no changes to the C level
344 interfaces to these functions.
345
2a27eeff
TC
346 - getpixel() and setpixel() now accept a mix of scalar and array
347 references for the x and y parameters, and unequal array lengths is
348 no longer an error.

360 - Win32 text output is now done in normal combine mode, the alpha
361 component of the color is now significant.

TC
496
497 - add simple tests for the Imager::Test test_image generators
498
6d5c85a2
TC
499 - io_glue I/O buffering re-work:
500
501 - reorganize io_glue to do it's own buffering by default
502
503 - the unbuffered functions are available as i_io_raw_read() (or
504 raw_read() from perl) etc but are not recommended for typical
505 use.
506
507 - use the new i_io_peekn() when checking for file magic to avoid
508 seek, allowing Imager to detect the file type and read the file
509 from an unseekable stream (for formats that don't use random
510 access)
511
512 - added several new I/O layer API functions.
513
514 - fix the TGA performance problem, most noticably on Win32
515 https://rt.cpan.org/Ticket/Display.html?id=70037
516
517 - TIFF now uses wrapper functions of the correct types to avoid casts
518 https://rt.cpan.org/Ticket/Display.html?id=69912
519
520 - the callback IO object did its own buffering, controlled by the
521 maxbuffer parameter supplied to the read() and write() methods.
522 This buffering has been removed, to avoid redundancy with the
523 common io_glue buffering. This also avoids a bug in that code
524 which could rarely pass a zero length to the read callback and
525 then panic about the result.
526
527 - the callback IO object now tests the result of calling the close
528 callback, which should return true for success.
529
530 - the PNM reader did its own buffering. This buffering has been
531 removed to avoid redundancy with the common io_glue buffering.
532
533 - previously the read handlers for fd and callback I/O layers would
534 call the underlying interface (POSIX read or your supplied callback)
535 until it filled the buffer. It now only makes one call.
536
537 - added public constructors for I/O layer objects (see Imager::IO)
538
539 - all core file handlers now use the i_io_foo() wrappers to gain
540 access to buffered I/O rather than calling the I/O layer
541 callbacks directly.
542
543 - all core file handlers now check for error on close.
544
545 - Backward compatibility: if you hava custom file handlers, you can
546 use i_io_write() etc since they're available as macros in older
547 versions of Imager.
548
549 - eliminate the final remnants of io_glue_commit_types().
550
551 - bump IMAGER_API_VERSION, since the above may break assumptions.
552
553 - removed the long unused i_gen_reader() and i_gen_writer() utility
554 functions.

562 dimensions and co-ordinated, and for memory block sizes.
563

565 lead to an infinite loop.

615==============
616
617Development release as a sanity check for the types re-work.
8d14daab
TC
618
619Massive types re-work:
620
621 - the type used internally for pixel co-ordinates and image sizes is
622 now 64-bit on 64-bit platforms (at least sane ones).
623
624 - size_t is now used consistently for memory block sizes.
625
626 - since this changes the binary interface, the Imager API version has
627 been incremented. Any module that uses the API will need to be
628 rebuilt. In most cases that will be enough, but calls to any APIs
629 that take a pointer to image sizes may need source changes.
630
631 - you should be able to create very large images on 64-bit systems,
632 if you have enough memory. Successfully created a 32768 x 49192 x
633 3 channel image, filled with a tiled image and scaled it. The
634 unscaled image was also successfully saved to a JPEG.
635
636 - check the image size before attempting to write BMP, GIF, JPEG,
637 PNG, SGI, TGA, TIFF images.
638
639 - correctly handle reading TGA images over 32767 pixels wide or tall.
640
641Incidental changes:
642
643 - the gif_left and gif_top tags are now clamped to non-negative
644 values when writing a GIF image.
645
646 - removed dead callback read/write code
647
648The default maximum memory size when reading files is now 1G.

1302
1303 - rubthrough() now falls back to pasting when the source doesn't have
1304 an alpha channel. This effectively treats the source as having a
1305 max alpha channel, the right thing to do.

1351 - some TGA images weren't being detected correctly as TGA images
1352 https://rt.cpan.org/Ticket/Display.html?id=32925
1353
1354 - handling of the left-over bit for 16-bit/pixel TGA images has been
1355 changed to match the behaviour of the GIMP. Previously the bit
1356 being set was treated as an opaque pixel, but one user reported a
1357 problem with loading such an image. I haven't been able to find any
1358 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1359 I'll match it's behaviour. See issue 114913 in the GIMP's
1360 bugzilla.

1370 - the old dynaload code used Mach API functions to load dynamic
1371 libraries on Mac OS X. These APIs have been deprecated in OS X
1372 10.5 and were causing some build problems.
1373 So henceforth Imager uses the dlopen() family of functions, and you
1374 will need version 10.3 or later of OS X.

1683Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1684
1685There is one new feature:

1689 http://rt.cpan.org/Ticket/Display.html?id=22166

1692
1693 - the string() method would not output the string "0"
1694 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1695
1696 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1697 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1698
1699 - the gif_disposal and gif_user_input tags weren't being read from
1700 the file correctly
1701 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1702
1703 - gif.c was failing to build under MSVC
1704 http://rt.cpan.org/Ticket/Display.html?id=23922
1705
1706 - in some cases strings passed to the string() method were treated as
1707 terminated by NUL (chr 0)
1708 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1709
1710 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1711 that's the default build name for zlib on Win32.
1712 http://rt.cpan.org/Ticket/Display.html?id=23064
1713
1714 - search $Config{incpath} for headers too, which we should have been
1715 doing all along.
1716
1717Win32 font driver fixes:
1718
1719 - the global descent value from bounding box was the wrong sign
1720 http://www.cpanforum.com/threads/3276
1721
1722 - if the first or last glyph overflowed the left or right side of the
1723 advance width they would be clipped
1724
1725
1726Imager 0.54 - 14 Sep 2006
1727===========
1728
1729This is primarily a feature release:
1730
1731 - a new qtype value 'mixing' has been added to the scale()
1732 method. This is faster than 'normal', slower than 'preview'. This
1733 is based on the method used by pnmscale, and seems to produce less
1734 blurry results than normal.
1735 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1736
1737 - the rubthrough() method can now render onto images with an alpha
1738 channel.
1739 http://rt.cpan.org/Ticket/Display.html?id=20678
1740
1741 - the read_multi() method now falls back to calling doing a single
1742 image read via the read() method and write_multi() will now fall
1743 back to calling write() if a single image is supplied. This means
1744 you can simply call the read_multi() or write_multi() functions
1745 without having to check if the type is formatted by that method.
1746 http://rt.cpan.org/Ticket/Display.html?id=19457
1747 http://rt.cpan.org/Ticket/Display.html?id=19458
1748
1749 - the GIF loop extension can now be written. If you don't have
1750 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1751 should upgrade.
1752 http://rt.cpan.org/Ticket/Display.html?id=21185
1753
1754 - getscanline() and setscanline() can now read/write palette index
1755 based data from/to the image for paletted images, by setting type to
1756 'index'.
1757 http://rt.cpan.org/Ticket/Display.html?id=20338
1758
1759 - we no longer hassle you to disable GIF support
1760 http://rt.cpan.org/Ticket/Display.html?id=20687
1761
1762 - minor documentation fixes

1776Imager 0.52 - 25 Jul 2006
1777===========
1778
1779This is primarily a feature release, but contains a fair few bug
1780fixes, new features:
1781
1782 - ability to read and write MS Windows ICO and CUR files
1783
1784 - you can now add file format plugins to support new file formats
1785
1786 - add POD coverage tests
1787
1788 - setcolors() and addcolors() now accept color names and so on
1789 instead of requiring Imager::Color objects.
1790 http://rt.cpan.org/Ticket/Display.html?id=20056
1791
1792 - flood_fill() can now fill to a specified border color instead of
1793 just to the area the same color as the seed.
1794 http://rt.cpan.org/Ticket/Display.html?id=19618
1795
1796
1797Bug fixes:
1798
1799 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1800 calculating the advance width.
1801 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1802
1803 - bounding_box for the T1 driver wasn't including leading and
1804 trailing spaces in the bounding box as the other drivers did, it also
1805 produced strange results for empty strings or strings containing only
1806 spaces
1807
1808 - when reading CMYK jpeg images they were being transferred to the
1809 image object as is, producing a four channel image. It only looked ok
1810 due to an old still unfixed Photoshop bug. We now convert from the
1811 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1812 http://rt.cpan.org/Ticket/Display.html?id=20416
1813
1814 - reading a CYMK TIFF would result in a 4 channel image, reading any
1815 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1816 result in an error.
1817 http://rt.cpan.org/Ticket/Display.html?id=20415
1818
1819 - added /usr/local/include to the default include search path, since
1820 we were already searching /usr/local/lib for libraries.
1821
1822And various minor fixes and documentation updates.
