3Imager 0.94_01 - 2 Mar 2013
4==============
5
14a4ea18 6 - NOTE: possibly backward incompatible:
3dcf7595
TC
7 support reading from/writing to perl filehandes that aren't raw
8 files.
9
10 This allows Imager's I/O to honour handles with layers such as
11 gzip, scalar file handles or tied file handles.
12
14a4ea18 13 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
14 use fileno() to retrieve the fd for the file and call write(2) etc
15 on it directly.

17
18 - moved most of README to lib/Imager/Install.pod which should make it

84Imager 0.93 - 15 Oct 2012
85===========
86
87Bug fixes:
71fbe41a
TC
88
89 - previously a transparency enabled GIF write (the default) would
90 always use a GIF89a header even if none of the images were
91 transparent.
7a5f7bc6 92
b2f967ef
TC
93 - previously the probe step for freetype-config would fail on cygwin
94
b2f967ef
TC
95 - catch an invalid matrix parameter to convert() instead of crashing
96 https://rt.cpan.org/Ticket/Display.html?id=79922
97
98 - remove the 16-bit/sample limitation from the documentation for
99 setsamples(), it hasn't applied for many releases.
100 https://rt.cpan.org/Ticket/Display.html?id=79989
101
9673d97e
TC
102 - don't copy setsamples() data parameter, it may be a large scalar

TC
112Enhancements:
113
114 - support for giflib 5.0. (5.0.1 and later)
115 https://rt.cpan.org/Ticket/Display.html?id=79029
116 The giflib API Imager uses doesn't have a mechanism to set the
117 header version in 5.0.0.
118
119 - update the GIF library probe code to check for the new giflib 5.0.1
120 EGifSetGifVersion() function, and to check for the giflib 4.2.0
121 uninitialized gif89 bug.
122 https://rt.cpan.org/Ticket/Display.html?id=79679
123 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
124
125 - avoid static variables when capturing IPTC data from JPEG files
126
127 - match Imager::Font;:T1's error message translations to those from
128 later versions of T1Lib.
129
130 - for libtiff versions that support extended warning handlers (3.8.0
131 or later), use them to avoid some global variables.
132
133 - note Image::ExifTool for better metadata support.

136Imager 0.92 - 14 Aug 2012
137===========
138
b1c75496
TC
139 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
140 correctly for both probing and runtime.
141 https://rt.cpan.org/Ticket/Display.html?id=77672
142

147Imager 0.91 - 4 Jun 2012
148===========
149
ef84bb32 150Bug fixes:
38742a13 151
289d65f4
TC
152 - The size of rotated images is no longer rounded up so aggressively.
153 Added rounding to the linear interpolation done for rotate() and
154 matrix_transform() for 1 and 3 channel 8-bit images.
155 Adjusted the two tranlate matrices used to build the final rotation
156 matrix to use the distance between the outlier pixels rather than
157 the pixel dimensions (ie. dimension-1).
158 With all of this the output of rotate(degrees => 270) on an 8-bit
159 image exactly matches the output of rotate(right => 270).
160 https://rt.cpan.org/Ticket/Display.html?id=77063
161
ef84bb32
TC
162Other changes:
163
164 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
165 internals, those names only matter for the XS interface.
166
167 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
168 the API level compiled into a loadable module such as
169 Imager::File::GIF doesn't match that of Imager. Previously it
170 could be difficult to determine exactly which module was failing to
171 load.
172 https://rt.cpan.org/Ticket/Display.html?id=77173
173
174 - added Imager->check_file_limits() as an interface to the
175 i_int_check_image_file_limits() API.
176
177 - Imager->set_file_limits(reset => 1) now resets the limits to the
178 defaults rather than setting them all to unlimited.
179
180 - wrote a brief security note as Imager::Security
181 https://rt.cpan.org/Ticket/Display.html?id=68910
182
6f31dd14 183Imager 0.90 - 30 Apr 2012
7c4464f5
TC
184===========
185
186Bug fixes:
187
188 - Imager::Test::is_imaged() attempted to process an "epsilon"
189 parameter but the prototype didn't allow for the extra parameter.
190 Corrected the prototype.
191
29b38678
TC
192 - when downconverting samples (eg. from floating point to 8 bit)
193 Imager now rounds the sample value rather than attempting to
194 allocate input values over output values equally. The old
195 behaviour had the probably surprising effect of converting a
196 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
197 2.
198 This may result in slightly different 8 or 16-bit output images.
199
e2a86bac
TC
200 - BI_BITFIELD BMP images were handled incorrectly, both in
201 incorrectly calculating the space required for the masks and in
202 processing the image data itself.
203 https://rt.cpan.org/Ticket/Display.html?id=76736
204
205 - some odd width BMP BI_RLE4 images use run lengths that run one off
206 the edge of the image. Imager now allows this, discarding the
207 extra column.
208
209 - odd length RLE4 runs in BMP images were decoded incorrectly.
210
82eb0687
TC
211 - pkg-config could sometimes return a library that was in a directory
212 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
213 If no -L is included in the pkg-config library information check if
214 EU::MM can find the library, and if not, search our configured
215 directories and insert that into the library flags.
216 https://rt.cpan.org/Ticket/Display.html?id=75869
217
de50f459
TC
218 - Imager::Probe can now probe for libraries with dependent libraries,
219 common for static linking, eg. libpng requires libz.
220 https://rt.cpan.org/Ticket/Display.html?id=74043
221
222 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
223
224 - added alternative probe configurations that try to link libz, to
225 handle a statically linked libpng.
226 https://rt.cpan.org/Ticket/Display.html?id=74043
227
228 - if a probe includes testcode, Imager::Probe now checks that code as
229 part of the process of checking each configuration rather than as a
230 post test of the found configuration. This allows alternate
231 configurations to be checked if a matching but non-working
232 configuration is found.
233 https://rt.cpan.org/Ticket/Display.html?id=74043
234
9d5ff8a6
TC
235Other changes:
236
237 - when reading or writing images via callbacks, the default callbacks
238 now push an error message indicating that a required callback was
239 called but not supplied.
240 https://rt.cpan.org/Ticket/Display.html?id=76782
241
242 - clarify which callbacks are required for reading and writing TIFF
243 images.
244
245 - improve logging for creation of callback I/O layers.
246
de50f459
TC
247 - a little more documentation for Imager::Probe.
248
594f5933
TC
249 - the i_get_file_background() and i_get_file_backgroundf() APIs now
250 return int to indicate whether the i_background tag was found.
251
1b46057d
TC
252 - PNG rework
253 - improve error reporting
254 - add png_interlace, png_bits tags
255 - read paletted images as paletted images, including transparency
256 - read 1 bit greyscale images as a type suitable for other file
257 handlers to write as bilevel
258 - read 16 bit/sample PNG as 16-bit/sample Imager images
259 - write "bilevel" paletted images as 1 bit grayscale images
260 - write paletted images as paletted images
261 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
262 images
263 - improved metadata support

266Imager 0.89 - 18 Mar 2012
267===========
268
269Bug fixes:
270
93eab01e
TC
271 - getpixel(..., type => "float") and the API i_gpixf() have been
272 broken on paletted images since they were implemented.
273 https://rt.cpan.org/Ticket/Display.html?id=75258
274
2c1ffb77
TC
275Other changes:
276
61be9694
TC
277 - links in the METHOD INDEX now point at the method documentation
278 rather than the heading you can find them under.
279 https://rt.cpan.org/Ticket/Display.html?id=71495
280
a5919365
TC
281 - Imager (and the bundled dynamic modules) no longer fallback to
282 using DynaLoader if loading via XSLoader fails.
283 For the bundled modules this could hide useful error messages.
284 https://rt.cpan.org/Ticket/Display.html?id=75560
285
335078fc
TC
286 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
287 buffer in the array of allocations, but just stores the filename
288 pointer and line number.
289 https://rt.cpan.org/Ticket/Display.html?id=70388

TC
291Imager 0.88 - 22 Feb 2012
292===========
293
43bef43b
TC
294 - describe how to build libgif etc on OS X in such a way as to be
295 compatible with a fat binary perl (such as the system perl), in
296 README.
297 https://rt.cpan.org/Ticket/Display.html?id=73371
298
69675eef
TC
299 - update the change notes for 0.77_01 to indicate that libungif
300 support was removed.

302 - add some other imaging modules to SEE ALSO
303 https://rt.cpan.org/Ticket/Display.html?id=73906
304
3b7f10da
TC
305 - note that the generator of the apparently non-DFSG-free postscript
306 in MMOne.pfb is a Debian package.
307
02323e69
TC
308 - setsamples() is now a true complement to getsamples() - it can
309 write 8-bit or floating point samples from a scalar or array
310 reference. This adds i_psamp() and i_psampf() to the C level API.
311
312 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
313 changed to make better use of the typemap, but these aren't part of
314 the perl level API anyway. There were no changes to the C level
315 interfaces to these functions.
316
2a27eeff
TC
317 - getpixel() and setpixel() now accept a mix of scalar and array
318 references for the x and y parameters, and unequal array lengths is
319 no longer an error.

341

342 - getpixel() and setpixel() now returns an empty list when invalid

467
468 - add simple tests for the Imager::Test test_image generators

TC
470 - io_glue I/O buffering re-work:
471
472 - reorganize io_glue to do it's own buffering by default
473
474 - the unbuffered functions are available as i_io_raw_read() (or
475 raw_read() from perl) etc but are not recommended for typical
476 use.
477
478 - use the new i_io_peekn() when checking for file magic to avoid
479 seek, allowing Imager to detect the file type and read the file
480 from an unseekable stream (for formats that don't use random
481 access)
482
483 - added several new I/O layer API functions.
484
485 - fix the TGA performance problem, most noticably on Win32
486 https://rt.cpan.org/Ticket/Display.html?id=70037
487
488 - TIFF now uses wrapper functions of the correct types to avoid casts
489 https://rt.cpan.org/Ticket/Display.html?id=69912
490
491 - the callback IO object did its own buffering, controlled by the
492 maxbuffer parameter supplied to the read() and write() methods.
493 This buffering has been removed, to avoid redundancy with the
494 common io_glue buffering. This also avoids a bug in that code
495 which could rarely pass a zero length to the read callback and
496 then panic about the result.
497
498 - the callback IO object now tests the result of calling the close
499 callback, which should return true for success.
500
501 - the PNM reader did its own buffering. This buffering has been
502 removed to avoid redundancy with the common io_glue buffering.
503
504 - previously the read handlers for fd and callback I/O layers would
505 call the underlying interface (POSIX read or your supplied callback)
506 until it filled the buffer. It now only makes one call.
507
508 - added public constructors for I/O layer objects (see Imager::IO)
509
510 - all core file handlers now use the i_io_foo() wrappers to gain
511 access to buffered I/O rather than calling the I/O layer
512 callbacks directly.
513
514 - all core file handlers now check for error on close.
515
516 - Backward compatibility: if you hava custom file handlers, you can
517 use i_io_write() etc since they're available as macros in older
518 versions of Imager.
519
520 - eliminate the final remnants of io_glue_commit_types().
521
522 - bump IMAGER_API_VERSION, since the above may break assumptions.
523
524 - removed the long unused i_gen_reader() and i_gen_writer() utility
525 functions.

588Development release as a sanity check for the types re-work.
8d14daab
TC
589
590Massive types re-work:
591
592 - the type used internally for pixel co-ordinates and image sizes is
593 now 64-bit on 64-bit platforms (at least sane ones).
594
595 - size_t is now used consistently for memory block sizes.
596
597 - since this changes the binary interface, the Imager API version has
598 been incremented. Any module that uses the API will need to be
599 rebuilt. In most cases that will be enough, but calls to any APIs
600 that take a pointer to image sizes may need source changes.
601
602 - you should be able to create very large images on 64-bit systems,
603 if you have enough memory. Successfully created a 32768 x 49192 x
604 3 channel image, filled with a tiled image and scaled it. The
605 unscaled image was also successfully saved to a JPEG.
606
607 - check the image size before attempting to write BMP, GIF, JPEG,
608 PNG, SGI, TGA, TIFF images.
609
610 - correctly handle reading TGA images over 32767 pixels wide or tall.
611
612Incidental changes:
613
614 - the gif_left and gif_top tags are now clamped to non-negative
615 values when writing a GIF image.
616
617 - removed dead callback read/write code
618
619The default maximum memory size when reading files is now 1G.

1273
1274 - rubthrough() now falls back to pasting when the source doesn't have
1275 an alpha channel. This effectively treats the source as having a
1276 max alpha channel, the right thing to do.

1283 defines them with respect to a translucent source and destination.

1341 - the old dynaload code used Mach API functions to load dynamic
1342 libraries on Mac OS X. These APIs have been deprecated in OS X
1343 10.5 and were causing some build problems.
1344 So henceforth Imager uses the dlopen() family of functions, and you
1345 will need version 10.3 or later of OS X.

1650===========

1652This is primarily a bug fix release.
1653
1654Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1655
1656There is one new feature:
1657
1658 - the Win32 font driver now supports UTF8 (RT 22166)
1659 http://www.cpanforum.com/threads/3276
1660 http://rt.cpan.org/Ticket/Display.html?id=22166

1662Several bugs were fixed:
1663
1664 - the string() method would not output the string "0"
1665 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1666
1667 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1668 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1669
1670 - the gif_disposal and gif_user_input tags weren't being read from
1671 the file correctly
1672 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1673
1674 - gif.c was failing to build under MSVC
1675 http://rt.cpan.org/Ticket/Display.html?id=23922
1676
1677 - in some cases strings passed to the string() method were treated as
1678 terminated by NUL (chr 0)
1679 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1680
1681 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1682 that's the default build name for zlib on Win32.
1683 http://rt.cpan.org/Ticket/Display.html?id=23064
1684
1685 - search $Config{incpath} for headers too, which we should have been
1686 doing all along.
1687
1688Win32 font driver fixes:
1689
1690 - the global descent value from bounding box was the wrong sign
1691 http://www.cpanforum.com/threads/3276
1692
1693 - if the first or last glyph overflowed the left or right side of the
1694 advance width they would be clipped

1696
1697Imager 0.54 - 14 Sep 2006
1698===========
1699
1700This is primarily a feature release:
1701
1702 - a new qtype value 'mixing' has been added to the scale()
1703 method. This is faster than 'normal', slower than 'preview'. This
1704 is based on the method used by pnmscale, and seems to produce less
1705 blurry results than normal.
1706 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1707
1708 - the rubthrough() method can now render onto images with an alpha
1709 channel.
1710 http://rt.cpan.org/Ticket/Display.html?id=20678
1711
1712 - the read_multi() method now falls back to calling doing a single
1713 image read via the read() method and write_multi() will now fall
1714 back to calling write() if a single image is supplied. This means
1715 you can simply call the read_multi() or write_multi() functions
1716 without having to check if the type is formatted by that method.
1717 http://rt.cpan.org/Ticket/Display.html?id=19457
1718 http://rt.cpan.org/Ticket/Display.html?id=19458
1719
1720 - the GIF loop extension can now be written. If you don't have
1721 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1722 should upgrade.
1723 http://rt.cpan.org/Ticket/Display.html?id=21185
1724
1725 - getscanline() and setscanline() can now read/write palette index
1726 based data from/to the image for paletted images, by setting type to
1727 'index'.
1728 http://rt.cpan.org/Ticket/Display.html?id=20338
1729
1730 - we no longer hassle you to disable GIF support
1731 http://rt.cpan.org/Ticket/Display.html?id=20687
1732
1733 - minor documentation fixes
1734
1735
1736Imager 0.53 - 26 Jul 2006
1737===========
1738
1739This is a bugfix release.
1740
1741Some test code was left in a code path not covered by the test
1742suite. A test was added to cover this code path and the test code was
1743removed.

1754
1755 - you can now add file format plugins to support new file formats
1756
1757 - add POD coverage tests
1758
1759 - setcolors() and addcolors() now accept color names and so on
1760 instead of requiring Imager::Color objects.
1761 http://rt.cpan.org/Ticket/Display.html?id=20056
1762
1763 - flood_fill() can now fill to a specified border color instead of
1764 just to the area the same color as the seed.
1765 http://rt.cpan.org/Ticket/Display.html?id=19618
1766
1767
1768Bug fixes:
1769
1770 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1771 calculating the advance width.

1774 - bounding_box for the T1 driver wasn't including leading and
1775 trailing spaces in the bounding box as the other drivers did, it also
1776 produced strange results for empty strings or strings containing only

1778

1780 image object as is, producing a four channel image. It only looked ok
1781 due to an old still unfixed Photoshop bug. We now convert from the
1782 inverted CMYK that photoshop (and Corel for example) produce into RGB.

1785 - reading a CYMK TIFF would result in a 4 channel image, reading any
1786 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1787 result in an error.
