TC
6 - enable debug logging for the standard font tests
7
8 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
9 due to a bug in that version of perl.
10
11 - don't test for read() failing on a write-only handle in 5.8.x and
12 earlier, this was fixed in change 862083f7e4 in perl.
13

14a4ea18 20 - NOTE: possibly backward incompatible:
3dcf7595
TC
21 support reading from/writing to perl filehandes that aren't raw
22 files.
23
24 This allows Imager's I/O to honour handles with layers such as
25 gzip, scalar file handles or tied file handles.
26
14a4ea18 27 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
28 use fileno() to retrieve the fd for the file and call write(2) etc
29 on it directly.

31
32 - moved most of README to lib/Imager/Install.pod which should make it
33 more accessible to the "web" generation, also significantly updated
34 and re-worked it.

98Imager 0.93 - 15 Oct 2012
99===========
100
101Bug fixes:
71fbe41a
TC
102
103 - previously a transparency enabled GIF write (the default) would
104 always use a GIF89a header even if none of the images were
105 transparent.
7a5f7bc6 106
b2f967ef
TC
107 - previously the probe step for freetype-config would fail on cygwin

110 https://rt.cpan.org/Ticket/Display.html?id=79922
111
112 - remove the 16-bit/sample limitation from the documentation for
113 setsamples(), it hasn't applied for many releases.

TC
126Enhancements:
127
128 - support for giflib 5.0. (5.0.1 and later)
129 https://rt.cpan.org/Ticket/Display.html?id=79029
130 The giflib API Imager uses doesn't have a mechanism to set the
131 header version in 5.0.0.
132
133 - update the GIF library probe code to check for the new giflib 5.0.1
134 EGifSetGifVersion() function, and to check for the giflib 4.2.0
135 uninitialized gif89 bug.
136 https://rt.cpan.org/Ticket/Display.html?id=79679
137 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
138
139 - avoid static variables when capturing IPTC data from JPEG files
140
141 - match Imager::Font;:T1's error message translations to those from
142 later versions of T1Lib.
143
144 - for libtiff versions that support extended warning handlers (3.8.0
145 or later), use them to avoid some global variables.
146
147 - note Image::ExifTool for better metadata support.

TC
153 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
154 correctly for both probing and runtime.

161Imager 0.91 - 4 Jun 2012
162===========
163
ef84bb32 164Bug fixes:
38742a13 165
289d65f4
TC
166 - The size of rotated images is no longer rounded up so aggressively.
167 Added rounding to the linear interpolation done for rotate() and
168 matrix_transform() for 1 and 3 channel 8-bit images.
169 Adjusted the two tranlate matrices used to build the final rotation
170 matrix to use the distance between the outlier pixels rather than
171 the pixel dimensions (ie. dimension-1).
172 With all of this the output of rotate(degrees => 270) on an 8-bit
173 image exactly matches the output of rotate(right => 270).
174 https://rt.cpan.org/Ticket/Display.html?id=77063
175
ef84bb32
TC
176Other changes:
177
178 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
179 internals, those names only matter for the XS interface.
180
181 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
182 the API level compiled into a loadable module such as
183 Imager::File::GIF doesn't match that of Imager. Previously it
184 could be difficult to determine exactly which module was failing to
185 load.
186 https://rt.cpan.org/Ticket/Display.html?id=77173
187
188 - added Imager->check_file_limits() as an interface to the
189 i_int_check_image_file_limits() API.
190
191 - Imager->set_file_limits(reset => 1) now resets the limits to the
192 defaults rather than setting them all to unlimited.
193
194 - wrote a brief security note as Imager::Security
195 https://rt.cpan.org/Ticket/Display.html?id=68910
196
6f31dd14 197Imager 0.90 - 30 Apr 2012
7c4464f5
TC
198===========
199
200Bug fixes:
201
202 - Imager::Test::is_imaged() attempted to process an "epsilon"
203 parameter but the prototype didn't allow for the extra parameter.
204 Corrected the prototype.
205
29b38678
TC
206 - when downconverting samples (eg. from floating point to 8 bit)
207 Imager now rounds the sample value rather than attempting to
208 allocate input values over output values equally. The old
209 behaviour had the probably surprising effect of converting a
210 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
211 2.
212 This may result in slightly different 8 or 16-bit output images.
213
e2a86bac
TC
214 - BI_BITFIELD BMP images were handled incorrectly, both in
215 incorrectly calculating the space required for the masks and in
216 processing the image data itself.
217 https://rt.cpan.org/Ticket/Display.html?id=76736
218
219 - some odd width BMP BI_RLE4 images use run lengths that run one off
220 the edge of the image. Imager now allows this, discarding the
221 extra column.
222
223 - odd length RLE4 runs in BMP images were decoded incorrectly.
224
82eb0687
TC
225 - pkg-config could sometimes return a library that was in a directory
226 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
227 If no -L is included in the pkg-config library information check if
228 EU::MM can find the library, and if not, search our configured
229 directories and insert that into the library flags.
230 https://rt.cpan.org/Ticket/Display.html?id=75869
231
de50f459
TC
232 - Imager::Probe can now probe for libraries with dependent libraries,
233 common for static linking, eg. libpng requires libz.
234 https://rt.cpan.org/Ticket/Display.html?id=74043
235
236 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
237
238 - added alternative probe configurations that try to link libz, to
239 handle a statically linked libpng.
240 https://rt.cpan.org/Ticket/Display.html?id=74043
241
242 - if a probe includes testcode, Imager::Probe now checks that code as
243 part of the process of checking each configuration rather than as a
244 post test of the found configuration. This allows alternate
245 configurations to be checked if a matching but non-working
246 configuration is found.
247 https://rt.cpan.org/Ticket/Display.html?id=74043
248
9d5ff8a6
TC
249Other changes:
250
251 - when reading or writing images via callbacks, the default callbacks
252 now push an error message indicating that a required callback was
253 called but not supplied.
254 https://rt.cpan.org/Ticket/Display.html?id=76782
255
256 - clarify which callbacks are required for reading and writing TIFF
257 images.
258
259 - improve logging for creation of callback I/O layers.
260
de50f459
TC
261 - a little more documentation for Imager::Probe.
262
594f5933
TC
263 - the i_get_file_background() and i_get_file_backgroundf() APIs now
264 return int to indicate whether the i_background tag was found.
265
1b46057d
TC
266 - PNG rework
267 - improve error reporting
268 - add png_interlace, png_bits tags
269 - read paletted images as paletted images, including transparency
270 - read 1 bit greyscale images as a type suitable for other file
271 handlers to write as bilevel
272 - read 16 bit/sample PNG as 16-bit/sample Imager images
273 - write "bilevel" paletted images as 1 bit grayscale images
274 - write paletted images as paletted images
275 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
276 images
277 - improved metadata support

TC
285 - getpixel(..., type => "float") and the API i_gpixf() have been
286 broken on paletted images since they were implemented.

288

TC
289Other changes:

61be9694
TC
291 - links in the METHOD INDEX now point at the method documentation
292 rather than the heading you can find them under.
293 https://rt.cpan.org/Ticket/Display.html?id=71495
294
a5919365
TC
295 - Imager (and the bundled dynamic modules) no longer fallback to
296 using DynaLoader if loading via XSLoader fails.
297 For the bundled modules this could hide useful error messages.
298 https://rt.cpan.org/Ticket/Display.html?id=75560
299
335078fc
TC
300 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
301 buffer in the array of allocations, but just stores the filename
302 pointer and line number.

306===========
307
43bef43b
TC
308 - describe how to build libgif etc on OS X in such a way as to be
309 compatible with a fat binary perl (such as the system perl), in
310 README.
311 https://rt.cpan.org/Ticket/Display.html?id=73371
312

317 https://rt.cpan.org/Ticket/Display.html?id=73906
318
3b7f10da
TC
319 - note that the generator of the apparently non-DFSG-free postscript
320 in MMOne.pfb is a Debian package.
321
02323e69
TC
322 - setsamples() is now a true complement to getsamples() - it can
323 write 8-bit or floating point samples from a scalar or array
324 reference. This adds i_psamp() and i_psampf() to the C level API.
325
326 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
327 changed to make better use of the typemap, but these aren't part of
328 the perl level API anyway. There were no changes to the C level
329 interfaces to these functions.
330
2a27eeff
TC
331 - getpixel() and setpixel() now accept a mix of scalar and array
332 references for the x and y parameters, and unequal array lengths is
333 no longer an error.

TC
481
482 - add simple tests for the Imager::Test test_image generators
483
6d5c85a2
TC
484 - io_glue I/O buffering re-work:
485
486 - reorganize io_glue to do it's own buffering by default
487
488 - the unbuffered functions are available as i_io_raw_read() (or
489 raw_read() from perl) etc but are not recommended for typical
490 use.
491
492 - use the new i_io_peekn() when checking for file magic to avoid
493 seek, allowing Imager to detect the file type and read the file
494 from an unseekable stream (for formats that don't use random
495 access)
496
497 - added several new I/O layer API functions.
498
499 - fix the TGA performance problem, most noticably on Win32
500 https://rt.cpan.org/Ticket/Display.html?id=70037
501
502 - TIFF now uses wrapper functions of the correct types to avoid casts
503 https://rt.cpan.org/Ticket/Display.html?id=69912
504
505 - the callback IO object did its own buffering, controlled by the
506 maxbuffer parameter supplied to the read() and write() methods.
507 This buffering has been removed, to avoid redundancy with the
508 common io_glue buffering. This also avoids a bug in that code
509 which could rarely pass a zero length to the read callback and
510 then panic about the result.
511
512 - the callback IO object now tests the result of calling the close
513 callback, which should return true for success.
514
515 - the PNM reader did its own buffering. This buffering has been
516 removed to avoid redundancy with the common io_glue buffering.
517
518 - previously the read handlers for fd and callback I/O layers would
519 call the underlying interface (POSIX read or your supplied callback)
520 until it filled the buffer. It now only makes one call.
521
522 - added public constructors for I/O layer objects (see Imager::IO)
523
524 - all core file handlers now use the i_io_foo() wrappers to gain
525 access to buffered I/O rather than calling the I/O layer
526 callbacks directly.
527
528 - all core file handlers now check for error on close.
529
530 - Backward compatibility: if you hava custom file handlers, you can
531 use i_io_write() etc since they're available as macros in older
532 versions of Imager.
533
534 - eliminate the final remnants of io_glue_commit_types().
535
536 - bump IMAGER_API_VERSION, since the above may break assumptions.
537
538 - removed the long unused i_gen_reader() and i_gen_writer() utility
539 functions.

547 dimensions and co-ordinated, and for memory block sizes.
548
549 - handle IFD loops in TIFF files correctly. Previously this would
550 lead to an infinite loop.

600==============
601
602Development release as a sanity check for the types re-work.
8d14daab
TC
603
604Massive types re-work:
605
606 - the type used internally for pixel co-ordinates and image sizes is
607 now 64-bit on 64-bit platforms (at least sane ones).
608
609 - size_t is now used consistently for memory block sizes.
610
611 - since this changes the binary interface, the Imager API version has
612 been incremented. Any module that uses the API will need to be
613 rebuilt. In most cases that will be enough, but calls to any APIs
614 that take a pointer to image sizes may need source changes.
615
616 - you should be able to create very large images on 64-bit systems,
617 if you have enough memory. Successfully created a 32768 x 49192 x
618 3 channel image, filled with a tiled image and scaled it. The
619 unscaled image was also successfully saved to a JPEG.
620
621 - check the image size before attempting to write BMP, GIF, JPEG,
622 PNG, SGI, TGA, TIFF images.
623
624 - correctly handle reading TGA images over 32767 pixels wide or tall.
625
626Incidental changes:
627
628 - the gif_left and gif_top tags are now clamped to non-negative
629 values when writing a GIF image.
630
631 - removed dead callback read/write code
632
633The default maximum memory size when reading files is now 1G.

1342 problem with loading such an image. I haven't been able to find any
1343 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1344 I'll match it's behaviour. See issue 114913 in the GIMP's
1345 bugzilla.

1355 - the old dynaload code used Mach API functions to load dynamic
1356 libraries on Mac OS X. These APIs have been deprecated in OS X
1357 10.5 and were causing some build problems.
1358 So henceforth Imager uses the dlopen() family of functions, and you
1359 will need version 10.3 or later of OS X.

1667
1668Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1669
1670There is one new feature:

1674 http://rt.cpan.org/Ticket/Display.html?id=22166

1680
1681 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1682 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1683
1684 - the gif_disposal and gif_user_input tags weren't being read from
1685 the file correctly
1686 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1687
1688 - gif.c was failing to build under MSVC
1689 http://rt.cpan.org/Ticket/Display.html?id=23922
1690
1691 - in some cases strings passed to the string() method were treated as
1692 terminated by NUL (chr 0)
1693 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1694
1695 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1696 that's the default build name for zlib on Win32.
1697 http://rt.cpan.org/Ticket/Display.html?id=23064
1698
1699 - search $Config{incpath} for headers too, which we should have been
1700 doing all along.

1703
1704 - the global descent value from bounding box was the wrong sign
1705 http://www.cpanforum.com/threads/3276

1711Imager 0.54 - 14 Sep 2006
1712===========
1713
1714This is primarily a feature release:
1715
1716 - a new qtype value 'mixing' has been added to the scale()
1717 method. This is faster than 'normal', slower than 'preview'. This
1718 is based on the method used by pnmscale, and seems to produce less
1719 blurry results than normal.
1720 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1721
1722 - the rubthrough() method can now render onto images with an alpha
1723 channel.
1724 http://rt.cpan.org/Ticket/Display.html?id=20678
1725
1726 - the read_multi() method now falls back to calling doing a single
1727 image read via the read() method and write_multi() will now fall
1728 back to calling write() if a single image is supplied. This means
1729 you can simply call the read_multi() or write_multi() functions
1730 without having to check if the type is formatted by that method.
1731 http://rt.cpan.org/Ticket/Display.html?id=19457
1732 http://rt.cpan.org/Ticket/Display.html?id=19458
1733
1734 - the GIF loop extension can now be written. If you don't have
1735 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1736 should upgrade.
1737 http://rt.cpan.org/Ticket/Display.html?id=21185
1738
1739 - getscanline() and setscanline() can now read/write palette index
1740 based data from/to the image for paletted images, by setting type to
1741 'index'.
1742 http://rt.cpan.org/Ticket/Display.html?id=20338
1743
1744 - we no longer hassle you to disable GIF support
1745 http://rt.cpan.org/Ticket/Display.html?id=20687
1746
1747 - minor documentation fixes
1748

1750Imager 0.53 - 26 Jul 2006
1751===========
1752
1753This is a bugfix release.

1774 instead of requiring Imager::Color objects.
1775 http://rt.cpan.org/Ticket/Display.html?id=20056
1776
1777 - flood_fill() can now fill to a specified border color instead of
1778 just to the area the same color as the seed.

1782Bug fixes:
1783
1784 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1785 calculating the advance width.
1786 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1787
1788 - bounding_box for the T1 driver wasn't including leading and
1789 trailing spaces in the bounding box as the other drivers did, it also
1790 produced strange results for empty strings or strings containing only
1791 spaces
1792
1793 - when reading CMYK jpeg images they were being transferred to the
1794 image object as is, producing a four channel image. It only looked ok
1795 due to an old still unfixed Photoshop bug. We now convert from the
1796 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1797 http://rt.cpan.org/Ticket/Display.html?id=20416
1798
1799 - reading a CYMK TIFF would result in a 4 channel image, reading any
1800 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1801 result in an error.
1802 http://rt.cpan.org/Ticket/Display.html?id=20415
1803
1804 - added /usr/local/include to the default include search path, since
1805 we were already searching /usr/local/lib for libraries.
1806
1807And various minor fixes and documentation updates.
