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

14
15 - moved most of README to lib/Imager/Install.pod which should make it
16 more accessible to the "web" generation, also significantly updated
17 and re-worked it.

55===========
56
57Bug fixes:
71fbe41a
TC
58
59 - previously a transparency enabled GIF write (the default) would
60 always use a GIF89a header even if none of the images were
61 transparent.

TC
63 - previously the probe step for freetype-config would fail on cygwin

82Enhancements:
83
84 - support for giflib 5.0. (5.0.1 and later)
85 https://rt.cpan.org/Ticket/Display.html?id=79029
86 The giflib API Imager uses doesn't have a mechanism to set the
87 header version in 5.0.0.
88
89 - update the GIF library probe code to check for the new giflib 5.0.1
90 EGifSetGifVersion() function, and to check for the giflib 4.2.0
91 uninitialized gif89 bug.
92 https://rt.cpan.org/Ticket/Display.html?id=79679
93 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
94
95 - avoid static variables when capturing IPTC data from JPEG files
96
97 - match Imager::Font;:T1's error message translations to those from
98 later versions of T1Lib.
99
100 - for libtiff versions that support extended warning handlers (3.8.0
101 or later), use them to avoid some global variables.
102
103 - note Image::ExifTool for better metadata support.

106Imager 0.92 - 14 Aug 2012
107===========

TC
109 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
110 correctly for both probing and runtime.
111 https://rt.cpan.org/Ticket/Display.html?id=77672
112

118===========
119
ef84bb32 120Bug fixes:
38742a13 121
289d65f4
TC
122 - The size of rotated images is no longer rounded up so aggressively.
123 Added rounding to the linear interpolation done for rotate() and
124 matrix_transform() for 1 and 3 channel 8-bit images.
125 Adjusted the two tranlate matrices used to build the final rotation
126 matrix to use the distance between the outlier pixels rather than
127 the pixel dimensions (ie. dimension-1).
128 With all of this the output of rotate(degrees => 270) on an 8-bit
129 image exactly matches the output of rotate(right => 270).
130 https://rt.cpan.org/Ticket/Display.html?id=77063
131
ef84bb32
TC
132Other changes:
133
134 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
135 internals, those names only matter for the XS interface.
136
137 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
138 the API level compiled into a loadable module such as
139 Imager::File::GIF doesn't match that of Imager. Previously it
140 could be difficult to determine exactly which module was failing to
141 load.
142 https://rt.cpan.org/Ticket/Display.html?id=77173
143
144 - added Imager->check_file_limits() as an interface to the
145 i_int_check_image_file_limits() API.
146
147 - Imager->set_file_limits(reset => 1) now resets the limits to the
148 defaults rather than setting them all to unlimited.
149
150 - wrote a brief security note as Imager::Security
151 https://rt.cpan.org/Ticket/Display.html?id=68910
152
6f31dd14 153Imager 0.90 - 30 Apr 2012
7c4464f5
TC
154===========
155
156Bug fixes:
157
158 - Imager::Test::is_imaged() attempted to process an "epsilon"
159 parameter but the prototype didn't allow for the extra parameter.
160 Corrected the prototype.
161
29b38678
TC
162 - when downconverting samples (eg. from floating point to 8 bit)
163 Imager now rounds the sample value rather than attempting to
164 allocate input values over output values equally. The old
165 behaviour had the probably surprising effect of converting a
166 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
167 2.
168 This may result in slightly different 8 or 16-bit output images.
169
e2a86bac
TC
170 - BI_BITFIELD BMP images were handled incorrectly, both in
171 incorrectly calculating the space required for the masks and in
172 processing the image data itself.
173 https://rt.cpan.org/Ticket/Display.html?id=76736
174
175 - some odd width BMP BI_RLE4 images use run lengths that run one off
176 the edge of the image. Imager now allows this, discarding the
177 extra column.
178
179 - odd length RLE4 runs in BMP images were decoded incorrectly.
180
82eb0687
TC
181 - pkg-config could sometimes return a library that was in a directory
182 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
183 If no -L is included in the pkg-config library information check if
184 EU::MM can find the library, and if not, search our configured
185 directories and insert that into the library flags.
186 https://rt.cpan.org/Ticket/Display.html?id=75869
187
de50f459
TC
188 - Imager::Probe can now probe for libraries with dependent libraries,
189 common for static linking, eg. libpng requires libz.
190 https://rt.cpan.org/Ticket/Display.html?id=74043
191
192 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
193
194 - added alternative probe configurations that try to link libz, to
195 handle a statically linked libpng.
196 https://rt.cpan.org/Ticket/Display.html?id=74043
197
198 - if a probe includes testcode, Imager::Probe now checks that code as
199 part of the process of checking each configuration rather than as a
200 post test of the found configuration. This allows alternate
201 configurations to be checked if a matching but non-working
202 configuration is found.
203 https://rt.cpan.org/Ticket/Display.html?id=74043
204
9d5ff8a6
TC
205Other changes:
206
207 - when reading or writing images via callbacks, the default callbacks
208 now push an error message indicating that a required callback was
209 called but not supplied.
210 https://rt.cpan.org/Ticket/Display.html?id=76782
211
212 - clarify which callbacks are required for reading and writing TIFF
213 images.
214
215 - improve logging for creation of callback I/O layers.
216
de50f459
TC
217 - a little more documentation for Imager::Probe.
218
594f5933
TC
219 - the i_get_file_background() and i_get_file_backgroundf() APIs now
220 return int to indicate whether the i_background tag was found.
221
1b46057d
TC
222 - PNG rework
223 - improve error reporting
224 - add png_interlace, png_bits tags
225 - read paletted images as paletted images, including transparency
226 - read 1 bit greyscale images as a type suitable for other file
227 handlers to write as bilevel
228 - read 16 bit/sample PNG as 16-bit/sample Imager images
229 - write "bilevel" paletted images as 1 bit grayscale images
230 - write paletted images as paletted images
231 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
232 images
233 - improved metadata support

236Imager 0.89 - 18 Mar 2012
237===========
238
239Bug fixes:
240
93eab01e
TC
241 - getpixel(..., type => "float") and the API i_gpixf() have been
242 broken on paletted images since they were implemented.

244
2c1ffb77
TC
245Other changes:
246
61be9694
TC
247 - links in the METHOD INDEX now point at the method documentation
248 rather than the heading you can find them under.
249 https://rt.cpan.org/Ticket/Display.html?id=71495
250
a5919365
TC
251 - Imager (and the bundled dynamic modules) no longer fallback to
252 using DynaLoader if loading via XSLoader fails.
253 For the bundled modules this could hide useful error messages.
254 https://rt.cpan.org/Ticket/Display.html?id=75560
255
335078fc
TC
256 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
257 buffer in the array of allocations, but just stores the filename
258 pointer and line number.

261Imager 0.88 - 22 Feb 2012
262===========
263
43bef43b
TC
264 - describe how to build libgif etc on OS X in such a way as to be
265 compatible with a fat binary perl (such as the system perl), in
266 README.
267 https://rt.cpan.org/Ticket/Display.html?id=73371
268
69675eef
TC
269 - update the change notes for 0.77_01 to indicate that libungif
270 support was removed.
271

TC
272 - add some other imaging modules to SEE ALSO
273 https://rt.cpan.org/Ticket/Display.html?id=73906
274
3b7f10da
TC
275 - note that the generator of the apparently non-DFSG-free postscript
276 in MMOne.pfb is a Debian package.
277
02323e69
TC
278 - setsamples() is now a true complement to getsamples() - it can
279 write 8-bit or floating point samples from a scalar or array
280 reference. This adds i_psamp() and i_psampf() to the C level API.
281
282 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
283 changed to make better use of the typemap, but these aren't part of
284 the perl level API anyway. There were no changes to the C level
285 interfaces to these functions.
286
2a27eeff
TC
287 - getpixel() and setpixel() now accept a mix of scalar and array
288 references for the x and y parameters, and unequal array lengths is
289 no longer an error.
290 https://rt.cpan.org/Ticket/Display.html?id=73697

300
5091168a
TC
301 - Win32 text output is now done in normal combine mode, the alpha
302 component of the color is now significant.

305 - remove long unused gif case from read()
306 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
307
7640e3bb
TC
308 - the getsamples() target parameter was being treated as a hashref
309 when it's meant to be an array reference.
310 https://rt.cpan.org/Ticket/Display.html?id=74882
311
2a27eeff
TC
312 - getpixel() and setpixel() now returns an empty list when invalid
313 parameters are supplied.
314 Invalid values for type now result in an error for getpixel().

TC
333 - make the error message from read() or read_multi() when they can't
334 identify the file type match reality.
335 https://rt.cpan.org/Ticket/Display.html?id=72475
336
337 - read() now uses $FORMATGUESS if it can't determine the file type
338 based on the file header, to match read_multi().
339
340 - re-work and add tests for def_guess_type(). def_guess_type() no
341 longer returns any random file extension as the file type.

TC
353 - fix i_render_color() to properly draw in "normal" mode - ie. when
354 writing to a 1 or 3 channel image the second or fourth channel of

402 engine.
403
6e938c74

439
6d5c85a2
TC
440 - io_glue I/O buffering re-work:
441
442 - reorganize io_glue to do it's own buffering by default
443
444 - the unbuffered functions are available as i_io_raw_read() (or
445 raw_read() from perl) etc but are not recommended for typical
446 use.
447
448 - use the new i_io_peekn() when checking for file magic to avoid
449 seek, allowing Imager to detect the file type and read the file
450 from an unseekable stream (for formats that don't use random
451 access)
452
453 - added several new I/O layer API functions.
454
455 - fix the TGA performance problem, most noticably on Win32
456 https://rt.cpan.org/Ticket/Display.html?id=70037
457
458 - TIFF now uses wrapper functions of the correct types to avoid casts
459 https://rt.cpan.org/Ticket/Display.html?id=69912
460
461 - the callback IO object did its own buffering, controlled by the
462 maxbuffer parameter supplied to the read() and write() methods.
463 This buffering has been removed, to avoid redundancy with the
464 common io_glue buffering. This also avoids a bug in that code
465 which could rarely pass a zero length to the read callback and
466 then panic about the result.
467
468 - the callback IO object now tests the result of calling the close
469 callback, which should return true for success.
470
471 - the PNM reader did its own buffering. This buffering has been
472 removed to avoid redundancy with the common io_glue buffering.
473
474 - previously the read handlers for fd and callback I/O layers would
475 call the underlying interface (POSIX read or your supplied callback)
476 until it filled the buffer. It now only makes one call.
477
478 - added public constructors for I/O layer objects (see Imager::IO)
479
480 - all core file handlers now use the i_io_foo() wrappers to gain
481 access to buffered I/O rather than calling the I/O layer
482 callbacks directly.
483
484 - all core file handlers now check for error on close.
485
486 - Backward compatibility: if you hava custom file handlers, you can
487 use i_io_write() etc since they're available as macros in older
488 versions of Imager.
489
490 - eliminate the final remnants of io_glue_commit_types().
491
492 - bump IMAGER_API_VERSION, since the above may break assumptions.
493
494 - removed the long unused i_gen_reader() and i_gen_writer() utility
495 functions.

TC
500The main changes in the release versus 0.84 are:
501
502 - on 64-bit systems, 64-bit types are consistently used for image
503 dimensions and co-ordinated, and for memory block sizes.
504
505 - handle IFD loops in TIFF files correctly. Previously this would
506 lead to an infinite loop.

555Imager 0.84_01 - 8 Aug 2011
556==============
557
558Development release as a sanity check for the types re-work.
8d14daab
TC
559
560Massive types re-work:
561
562 - the type used internally for pixel co-ordinates and image sizes is
563 now 64-bit on 64-bit platforms (at least sane ones).
564
565 - size_t is now used consistently for memory block sizes.
566
567 - since this changes the binary interface, the Imager API version has
568 been incremented. Any module that uses the API will need to be
569 rebuilt. In most cases that will be enough, but calls to any APIs
570 that take a pointer to image sizes may need source changes.
571
572 - you should be able to create very large images on 64-bit systems,
573 if you have enough memory. Successfully created a 32768 x 49192 x
574 3 channel image, filled with a tiled image and scaled it. The
575 unscaled image was also successfully saved to a JPEG.
576
577 - check the image size before attempting to write BMP, GIF, JPEG,
578 PNG, SGI, TGA, TIFF images.
579
580 - correctly handle reading TGA images over 32767 pixels wide or tall.
581
582Incidental changes:
583
584 - the gif_left and gif_top tags are now clamped to non-negative
585 values when writing a GIF image.
586
587 - removed dead callback read/write code
588
589The default maximum memory size when reading files is now 1G.

915 - added the ability to read multiple-image PNM files.
916 Note that unlike the pbm/pgm/ppm specification this accepts mixed
917 format files and allows white space padding between files.

1036 - the conv filter now enforces that the sum of the coefficients is
1037 non-zero. Also, rather than skipping pixels off the edge off the
1038 edge of the image, the closest edge pixel is used. Previously
1039 dividing by the zero sum of coefficients could cause invalid

1227This release primarily contains changes to improve ease of use -
1228rather than you having to convert images to the appropriate number of

TC
1236 - moved the imtoc.perl code into Imager::Preprocess

1238 - paste() and rubthrough() now adapt the source image data to the
1239 destination, so you can now safely paste/rubthrough from greyscale

1241 noalpha channels or back.
1242 https://rt.cpan.org/Ticket/Display.html?id=30908
1243
1244 - rubthrough() now falls back to pasting when the source doesn't have
1245 an alpha channel. This effectively treats the source as having a
1246 max alpha channel, the right thing to do.
1247 http://rt.cpan.org/Ticket/Display.html?id=29944
1248
1249 - re-worked most of the area filling code to use a common set of
1250 functions when filling.
1251 Corrected normal combine mode.
1252 Rewrote most of the combine modes to match the way the SVG draft
1253 defines them with respect to a translucent source and destination.
1254 Added tests for translucent source and destination.
1255 Added tests to check 8-bit/sample and double/sample combines work
1256 similarly.

1297 being set was treated as an opaque pixel, but one user reported a
1298 problem with loading such an image. I haven't been able to find any
1299 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1300 I'll match it's behaviour. See issue 114913 in the GIMP's

1343 - major TIFF support re-work
1344 http://rt.cpan.org/Ticket/Display.html?id=20329
1345
1346 - added a C level image interface for accessing samples from 1-32
1347 bits, exposed this at the perl level in getsamples()
1348
1349 - the conv filter now works at floating point precision for high bit
1350 images
1351
1352 - added is_bilevel method to test whether an image should be written as
1353 a bilevel image if the image format supports it.
1354

1361Bug fixes:
1362
1363 - Imager::Fountain couldn't read GIMP gradient files with 10 or more

1413 - the SGI RLE compression code could overflow its compression buffer
1414 http://rt.cpan.org/Ticket/Display.html?id=30334
1415
1416 - the 32-bit output function used by the SGI code only handled values
1417 under 0x10000. This was most noticable when writing large RLE images.

TC
1458 - the mask for ICO/CUR images is now applied as an alpha channel to
1459 the returned image. For the old behaviour, supply ico_masked => 0
1460 to read() or read_multi(). This should be less confusing when
1461 using Imager as a general image processor.

1464Bug fixes:
1465
1466 - in some cases it's possible for giflib/libungif to return color
1467 indexes outside the range of colors defined by the image's palette.
1468 We now expand the palette to match the indexes used.
1469 Thanks to Gabriel Vasseur for reporting this.

TC
1471 - fixed various memory leaks that could occur when failing to read png,
1472 jpeg, bmp or tga files.
1473
b3aa972f
TC
1474 - to avoid confusion, channels not present in the image are returned as
1475 zero by getscanline(). This has no effect on the C level i_glin()
1476 and i_glinf() API functions which continue to not set the unused
1477 channels.
1478
d5477d3d
TC
1479 - the convert() method now returns an image of the same sample size as
1480 the source image.

1548 function for a library. Disabled the default (non-freetype-config)
1549 library probe and added an extra probe function that searches for
1550 both ft2build.h and whatever it includes, and adds -I as needed.

1619Imager 0.55 - 16 Dec 2006
1620===========
1621
1622This is primarily a bug fix release.
1623
1624Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1625
1626There is one new feature:
1627
1628 - the Win32 font driver now supports UTF8 (RT 22166)
1629 http://www.cpanforum.com/threads/3276
1630 http://rt.cpan.org/Ticket/Display.html?id=22166
1631
1632Several bugs were fixed:
1633
1634 - the string() method would not output the string "0"
1635 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1636
1637 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1638 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1639
1640 - the gif_disposal and gif_user_input tags weren't being read from
1641 the file correctly
1642 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1643
1644 - gif.c was failing to build under MSVC
1645 http://rt.cpan.org/Ticket/Display.html?id=23922
1646
1647 - in some cases strings passed to the string() method were treated as
1648 terminated by NUL (chr 0)
1649 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1650
1651 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1652 that's the default build name for zlib on Win32.
1653 http://rt.cpan.org/Ticket/Display.html?id=23064
1654
1655 - search $Config{incpath} for headers too, which we should have been
1656 doing all along.
1657
1658Win32 font driver fixes:
1659
1660 - the global descent value from bounding box was the wrong sign
1661 http://www.cpanforum.com/threads/3276
1662
1663 - if the first or last glyph overflowed the left or right side of the
1664 advance width they would be clipped
1665
1666
1667Imager 0.54 - 14 Sep 2006
1668===========
1669
1670This is primarily a feature release:
1671
1672 - a new qtype value 'mixing' has been added to the scale()
1673 method. This is faster than 'normal', slower than 'preview'. This
1674 is based on the method used by pnmscale, and seems to produce less
1675 blurry results than normal.
1676 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1677
1678 - the rubthrough() method can now render onto images with an alpha
1679 channel.
1680 http://rt.cpan.org/Ticket/Display.html?id=20678
1681
1682 - the read_multi() method now falls back to calling doing a single
1683 image read via the read() method and write_multi() will now fall
1684 back to calling write() if a single image is supplied. This means
1685 you can simply call the read_multi() or write_multi() functions
1686 without having to check if the type is formatted by that method.
1687 http://rt.cpan.org/Ticket/Display.html?id=19457
1688 http://rt.cpan.org/Ticket/Display.html?id=19458
1689
1690 - the GIF loop extension can now be written. If you don't have
1691 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1692 should upgrade.
1693 http://rt.cpan.org/Ticket/Display.html?id=21185
1694
1695 - getscanline() and setscanline() can now read/write palette index
1696 based data from/to the image for paletted images, by setting type to
1697 'index'.
1698 http://rt.cpan.org/Ticket/Display.html?id=20338
1699
1700 - we no longer hassle you to disable GIF support
1701 http://rt.cpan.org/Ticket/Display.html?id=20687
1702
1703 - minor documentation fixes
1704
1705
1706Imager 0.53 - 26 Jul 2006
1707===========
1708
1709This is a bugfix release.
1710
1711Some test code was left in a code path not covered by the test
1712suite. A test was added to cover this code path and the test code was
1713removed.
1714http://rt.cpan.org/Public/Bug/Display.html?id=20705
1715
1716
1717Imager 0.52 - 25 Jul 2006
1718===========
1719
1720This is primarily a feature release, but contains a fair few bug
1721fixes, new features:
1722
1723 - ability to read and write MS Windows ICO and CUR files
1724
1725 - you can now add file format plugins to support new file formats
1726
1727 - add POD coverage tests
1728
1729 - setcolors() and addcolors() now accept color names and so on
1730 instead of requiring Imager::Color objects.
1731 http://rt.cpan.org/Ticket/Display.html?id=20056
1732
1733 - flood_fill() can now fill to a specified border color instead of
1734 just to the area the same color as the seed.
1735 http://rt.cpan.org/Ticket/Display.html?id=19618
1736
1737
1738Bug fixes:
1739
1740 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1741 calculating the advance width.
1742 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1743
1744 - bounding_box for the T1 driver wasn't including leading and
1745 trailing spaces in the bounding box as the other drivers did, it also
1746 produced strange results for empty strings or strings containing only
1747 spaces
1748
1749 - when reading CMYK jpeg images they were being transferred to the
1750 image object as is, producing a four channel image. It only looked ok
1751 due to an old still unfixed Photoshop bug. We now convert from the
1752 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1753 http://rt.cpan.org/Ticket/Display.html?id=20416
1754
1755 - reading a CYMK TIFF would result in a 4 channel image, reading any
1756 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1757 result in an error.
1758 http://rt.cpan.org/Ticket/Display.html?id=20415
1759
1760 - added /usr/local/include to the default include search path, since
1761 we were already searching /usr/local/lib for libraries.
1762
1763And various minor fixes and documentation updates.
1764
1765
1766Imager 0.51 - 23 Apr 2006
1767===========
1768
1769 - fix a validation bug when processing JPEG EXIF data that can cause
1770 a crash
1771 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1772
1773 - fix mis-processing of the src_maxx and src_maxy parameters of the
1774 paste() method
1775 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1777 - fix a problem in Imager's "smart" handling of the color parameter
1778 to various methods.
