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.

54Bug fixes:
71fbe41a
TC
55
56 - previously a transparency enabled GIF write (the default) would
57 always use a GIF89a header even if none of the images were
58 transparent.

79Enhancements:
80
81 - support for giflib 5.0. (5.0.1 and later)
82 https://rt.cpan.org/Ticket/Display.html?id=79029
83 The giflib API Imager uses doesn't have a mechanism to set the
84 header version in 5.0.0.
85
86 - update the GIF library probe code to check for the new giflib 5.0.1
87 EGifSetGifVersion() function, and to check for the giflib 4.2.0
88 uninitialized gif89 bug.
89 https://rt.cpan.org/Ticket/Display.html?id=79679
90 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
91
92 - avoid static variables when capturing IPTC data from JPEG files
93
94 - match Imager::Font;:T1's error message translations to those from
95 later versions of T1Lib.
96
97 - for libtiff versions that support extended warning handlers (3.8.0
98 or later), use them to avoid some global variables.
99
100 - note Image::ExifTool for better metadata support.

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

ef84bb32 117Bug fixes:
38742a13 118
289d65f4
TC
119 - The size of rotated images is no longer rounded up so aggressively.
120 Added rounding to the linear interpolation done for rotate() and
121 matrix_transform() for 1 and 3 channel 8-bit images.
122 Adjusted the two tranlate matrices used to build the final rotation
123 matrix to use the distance between the outlier pixels rather than
124 the pixel dimensions (ie. dimension-1).
125 With all of this the output of rotate(degrees => 270) on an 8-bit
126 image exactly matches the output of rotate(right => 270).
127 https://rt.cpan.org/Ticket/Display.html?id=77063
128
ef84bb32
TC
129Other changes:
130
131 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
132 internals, those names only matter for the XS interface.
133
134 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
135 the API level compiled into a loadable module such as
136 Imager::File::GIF doesn't match that of Imager. Previously it
137 could be difficult to determine exactly which module was failing to
138 load.
139 https://rt.cpan.org/Ticket/Display.html?id=77173
140
141 - added Imager->check_file_limits() as an interface to the
142 i_int_check_image_file_limits() API.
143
144 - Imager->set_file_limits(reset => 1) now resets the limits to the
145 defaults rather than setting them all to unlimited.
146
147 - wrote a brief security note as Imager::Security
148 https://rt.cpan.org/Ticket/Display.html?id=68910
149
6f31dd14 150Imager 0.90 - 30 Apr 2012
7c4464f5
TC
151===========
152
153Bug fixes:
154
155 - Imager::Test::is_imaged() attempted to process an "epsilon"
156 parameter but the prototype didn't allow for the extra parameter.
157 Corrected the prototype.
158
29b38678
TC
159 - when downconverting samples (eg. from floating point to 8 bit)
160 Imager now rounds the sample value rather than attempting to
161 allocate input values over output values equally. The old
162 behaviour had the probably surprising effect of converting a
163 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
164 2.
165 This may result in slightly different 8 or 16-bit output images.
166
e2a86bac
TC
167 - BI_BITFIELD BMP images were handled incorrectly, both in
168 incorrectly calculating the space required for the masks and in
169 processing the image data itself.
170 https://rt.cpan.org/Ticket/Display.html?id=76736
171
172 - some odd width BMP BI_RLE4 images use run lengths that run one off
173 the edge of the image. Imager now allows this, discarding the
174 extra column.
175
176 - odd length RLE4 runs in BMP images were decoded incorrectly.
177
82eb0687
TC
178 - pkg-config could sometimes return a library that was in a directory
179 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
180 If no -L is included in the pkg-config library information check if
181 EU::MM can find the library, and if not, search our configured
182 directories and insert that into the library flags.
183 https://rt.cpan.org/Ticket/Display.html?id=75869
184
de50f459
TC
185 - Imager::Probe can now probe for libraries with dependent libraries,
186 common for static linking, eg. libpng requires libz.
187 https://rt.cpan.org/Ticket/Display.html?id=74043
188
189 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
190
191 - added alternative probe configurations that try to link libz, to
192 handle a statically linked libpng.
193 https://rt.cpan.org/Ticket/Display.html?id=74043
194
195 - if a probe includes testcode, Imager::Probe now checks that code as
196 part of the process of checking each configuration rather than as a
197 post test of the found configuration. This allows alternate
198 configurations to be checked if a matching but non-working
199 configuration is found.
200 https://rt.cpan.org/Ticket/Display.html?id=74043
201
9d5ff8a6
TC
202Other changes:
203
204 - when reading or writing images via callbacks, the default callbacks
205 now push an error message indicating that a required callback was
206 called but not supplied.
207 https://rt.cpan.org/Ticket/Display.html?id=76782
208
209 - clarify which callbacks are required for reading and writing TIFF
210 images.
211
212 - improve logging for creation of callback I/O layers.
213
de50f459
TC
214 - a little more documentation for Imager::Probe.
215
594f5933
TC
216 - the i_get_file_background() and i_get_file_backgroundf() APIs now
217 return int to indicate whether the i_background tag was found.
218
1b46057d
TC
219 - PNG rework
220 - improve error reporting
221 - add png_interlace, png_bits tags
222 - read paletted images as paletted images, including transparency
223 - read 1 bit greyscale images as a type suitable for other file
224 handlers to write as bilevel
225 - read 16 bit/sample PNG as 16-bit/sample Imager images
226 - write "bilevel" paletted images as 1 bit grayscale images
227 - write paletted images as paletted images
228 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
229 images
230 - improved metadata support

233Imager 0.89 - 18 Mar 2012
234===========
235
236Bug fixes:
237
93eab01e
TC
238 - getpixel(..., type => "float") and the API i_gpixf() have been
239 broken on paletted images since they were implemented.

TC
242Other changes:
243
61be9694
TC
244 - links in the METHOD INDEX now point at the method documentation
245 rather than the heading you can find them under.
246 https://rt.cpan.org/Ticket/Display.html?id=71495
247
a5919365
TC
248 - Imager (and the bundled dynamic modules) no longer fallback to
249 using DynaLoader if loading via XSLoader fails.
250 For the bundled modules this could hide useful error messages.
251 https://rt.cpan.org/Ticket/Display.html?id=75560
252
335078fc
TC
253 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
254 buffer in the array of allocations, but just stores the filename
255 pointer and line number.

258Imager 0.88 - 22 Feb 2012
259===========
260
43bef43b
TC
261 - describe how to build libgif etc on OS X in such a way as to be
262 compatible with a fat binary perl (such as the system perl), in
263 README.
264 https://rt.cpan.org/Ticket/Display.html?id=73371
265

270 https://rt.cpan.org/Ticket/Display.html?id=73906
271
3b7f10da
TC
272 - note that the generator of the apparently non-DFSG-free postscript
273 in MMOne.pfb is a Debian package.
274
02323e69
TC
275 - setsamples() is now a true complement to getsamples() - it can
276 write 8-bit or floating point samples from a scalar or array
277 reference. This adds i_psamp() and i_psampf() to the C level API.
278
279 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
280 changed to make better use of the typemap, but these aren't part of
281 the perl level API anyway. There were no changes to the C level
282 interfaces to these functions.
283
2a27eeff
TC
284 - getpixel() and setpixel() now accept a mix of scalar and array
285 references for the x and y parameters, and unequal array lengths is
286 no longer an error.

297
5091168a
TC
298 - Win32 text output is now done in normal combine mode, the alpha
299 component of the color is now significant.

302 - remove long unused gif case from read()
303 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
304
7640e3bb
TC
305 - the getsamples() target parameter was being treated as a hashref
306 when it's meant to be an array reference.
307 https://rt.cpan.org/Ticket/Display.html?id=74882
308
2a27eeff
TC
309 - getpixel() and setpixel() now returns an empty list when invalid
310 parameters are supplied.
311 Invalid values for type now result in an error for getpixel().

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

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

399 engine.
400

434
435 - add simple tests for the Imager::Test test_image generators
436
6d5c85a2
TC
437 - io_glue I/O buffering re-work:
438
439 - reorganize io_glue to do it's own buffering by default
440
441 - the unbuffered functions are available as i_io_raw_read() (or
442 raw_read() from perl) etc but are not recommended for typical
443 use.
444
445 - use the new i_io_peekn() when checking for file magic to avoid
446 seek, allowing Imager to detect the file type and read the file
447 from an unseekable stream (for formats that don't use random
448 access)
449
450 - added several new I/O layer API functions.
451
452 - fix the TGA performance problem, most noticably on Win32
453 https://rt.cpan.org/Ticket/Display.html?id=70037

455 - TIFF now uses wrapper functions of the correct types to avoid casts
456 https://rt.cpan.org/Ticket/Display.html?id=69912
457
458 - the callback IO object did its own buffering, controlled by the
459 maxbuffer parameter supplied to the read() and write() methods.
460 This buffering has been removed, to avoid redundancy with the
461 common io_glue buffering. This also avoids a bug in that code
462 which could rarely pass a zero length to the read callback and
463 then panic about the result.
464
465 - the callback IO object now tests the result of calling the close
466 callback, which should return true for success.
467
468 - the PNM reader did its own buffering. This buffering has been
469 removed to avoid redundancy with the common io_glue buffering.
470
471 - previously the read handlers for fd and callback I/O layers would
472 call the underlying interface (POSIX read or your supplied callback)
473 until it filled the buffer. It now only makes one call.
474
475 - added public constructors for I/O layer objects (see Imager::IO)
476
477 - all core file handlers now use the i_io_foo() wrappers to gain
478 access to buffered I/O rather than calling the I/O layer
479 callbacks directly.
480
481 - all core file handlers now check for error on close.
482
483 - Backward compatibility: if you hava custom file handlers, you can
484 use i_io_write() etc since they're available as macros in older
485 versions of Imager.
486
487 - eliminate the final remnants of io_glue_commit_types().
488
489 - bump IMAGER_API_VERSION, since the above may break assumptions.
490
491 - removed the long unused i_gen_reader() and i_gen_writer() utility
492 functions.

497The main changes in the release versus 0.84 are:
498
499 - on 64-bit systems, 64-bit types are consistently used for image
500 dimensions and co-ordinated, and for memory block sizes.
501
502 - handle IFD loops in TIFF files correctly. Previously this would
503 lead to an infinite loop.

552Imager 0.84_01 - 8 Aug 2011
553==============
554
555Development release as a sanity check for the types re-work.
8d14daab
TC
556
557Massive types re-work:
558
559 - the type used internally for pixel co-ordinates and image sizes is
560 now 64-bit on 64-bit platforms (at least sane ones).
561
562 - size_t is now used consistently for memory block sizes.
563
564 - since this changes the binary interface, the Imager API version has
565 been incremented. Any module that uses the API will need to be
566 rebuilt. In most cases that will be enough, but calls to any APIs
567 that take a pointer to image sizes may need source changes.
568
569 - you should be able to create very large images on 64-bit systems,
570 if you have enough memory. Successfully created a 32768 x 49192 x
571 3 channel image, filled with a tiled image and scaled it. The
572 unscaled image was also successfully saved to a JPEG.
573
574 - check the image size before attempting to write BMP, GIF, JPEG,
575 PNG, SGI, TGA, TIFF images.
576
577 - correctly handle reading TGA images over 32767 pixels wide or tall.
578
579Incidental changes:
580
581 - the gif_left and gif_top tags are now clamped to non-negative
582 values when writing a GIF image.
583
584 - removed dead callback read/write code
585
586The default maximum memory size when reading files is now 1G.

912 - added the ability to read multiple-image PNM files.
913 Note that unlike the pbm/pgm/ppm specification this accepts mixed

1233 - moved the imtoc.perl code into Imager::Preprocess

1238 noalpha channels or back.

1241 - rubthrough() now falls back to pasting when the source doesn't have
1242 an alpha channel. This effectively treats the source as having a
1243 max alpha channel, the right thing to do.
1244 http://rt.cpan.org/Ticket/Display.html?id=29944

1249 Rewrote most of the combine modes to match the way the SVG draft
1250 defines them with respect to a translucent source and destination.

1295 problem with loading such an image. I haven't been able to find any
1296 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1297 I'll match it's behaviour. See issue 114913 in the GIMP's

1343 - added a C level image interface for accessing samples from 1-32
1344 bits, exposed this at the perl level in getsamples()
1345
1346 - the conv filter now works at floating point precision for high bit
1347 images

1455 - the mask for ICO/CUR images is now applied as an alpha channel to

1616Imager 0.55 - 16 Dec 2006
1617===========
1618
1619This is primarily a bug fix release.
1620
1621Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1622
1623There is one new feature:
1624
1625 - the Win32 font driver now supports UTF8 (RT 22166)
1626 http://www.cpanforum.com/threads/3276
1627 http://rt.cpan.org/Ticket/Display.html?id=22166
1628
1629Several bugs were fixed:
1630
1631 - the string() method would not output the string "0"
1632 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1633
1634 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1635 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1636
1637 - the gif_disposal and gif_user_input tags weren't being read from
1638 the file correctly
1639 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1640
1641 - gif.c was failing to build under MSVC
1642 http://rt.cpan.org/Ticket/Display.html?id=23922
1643
1644 - in some cases strings passed to the string() method were treated as
1645 terminated by NUL (chr 0)
1646 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1647
1648 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1649 that's the default build name for zlib on Win32.
1650 http://rt.cpan.org/Ticket/Display.html?id=23064
1651
1652 - search $Config{incpath} for headers too, which we should have been
1653 doing all along.
1654
1655Win32 font driver fixes:
1656
1657 - the global descent value from bounding box was the wrong sign
1658 http://www.cpanforum.com/threads/3276
1659
1660 - if the first or last glyph overflowed the left or right side of the
1661 advance width they would be clipped
1662
1663
1664Imager 0.54 - 14 Sep 2006
1665===========
1666
1667This is primarily a feature release:
1668
1669 - a new qtype value 'mixing' has been added to the scale()
1670 method. This is faster than 'normal', slower than 'preview'. This
1671 is based on the method used by pnmscale, and seems to produce less
1672 blurry results than normal.
1673 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1674
1675 - the rubthrough() method can now render onto images with an alpha
1676 channel.
1677 http://rt.cpan.org/Ticket/Display.html?id=20678
1678
1679 - the read_multi() method now falls back to calling doing a single
1680 image read via the read() method and write_multi() will now fall
1681 back to calling write() if a single image is supplied. This means
1682 you can simply call the read_multi() or write_multi() functions
1683 without having to check if the type is formatted by that method.
1684 http://rt.cpan.org/Ticket/Display.html?id=19457
1685 http://rt.cpan.org/Ticket/Display.html?id=19458
1686
1687 - the GIF loop extension can now be written. If you don't have
1688 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1689 should upgrade.
1690 http://rt.cpan.org/Ticket/Display.html?id=21185
1691
1692 - getscanline() and setscanline() can now read/write palette index
1693 based data from/to the image for paletted images, by setting type to
1694 'index'.
1695 http://rt.cpan.org/Ticket/Display.html?id=20338
1696
1697 - we no longer hassle you to disable GIF support
1698 http://rt.cpan.org/Ticket/Display.html?id=20687
1699
1700 - minor documentation fixes
1701
1702
1703Imager 0.53 - 26 Jul 2006
1704===========
1705
1706This is a bugfix release.
1707
1708Some test code was left in a code path not covered by the test
1709suite. A test was added to cover this code path and the test code was
1710removed.

1713
1714Imager 0.52 - 25 Jul 2006
1715===========
1716
1717This is primarily a feature release, but contains a fair few bug
1718fixes, new features:
1719
1720 - ability to read and write MS Windows ICO and CUR files
1721
1722 - you can now add file format plugins to support new file formats
1723
1724 - add POD coverage tests
1725
1726 - setcolors() and addcolors() now accept color names and so on
1727 instead of requiring Imager::Color objects.
1728 http://rt.cpan.org/Ticket/Display.html?id=20056
1729
1730 - flood_fill() can now fill to a specified border color instead of
1731 just to the area the same color as the seed.
1732 http://rt.cpan.org/Ticket/Display.html?id=19618
1733
1734
1735Bug fixes:
1736
1737 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1738 calculating the advance width.
1739 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1740
1741 - bounding_box for the T1 driver wasn't including leading and
1742 trailing spaces in the bounding box as the other drivers did, it also
1743 produced strange results for empty strings or strings containing only
1744 spaces
1745
1746 - when reading CMYK jpeg images they were being transferred to the
1747 image object as is, producing a four channel image. It only looked ok
1748 due to an old still unfixed Photoshop bug. We now convert from the
1749 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1750 http://rt.cpan.org/Ticket/Display.html?id=20416
1751
1752 - reading a CYMK TIFF would result in a 4 channel image, reading any
1753 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1754 result in an error.
1755 http://rt.cpan.org/Ticket/Display.html?id=20415
1756
1757 - added /usr/local/include to the default include search path, since
1758 we were already searching /usr/local/lib for libraries.
1759
1760And various minor fixes and documentation updates.
1761
1762
1763Imager 0.51 - 23 Apr 2006
1764===========
1765
1766 - fix a validation bug when processing JPEG EXIF data that can cause
1767 a crash
1768 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1769
1770 - fix mis-processing of the src_maxx and src_maxy parameters of the
1771 paste() method
1772 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1774 - fix a problem in Imager's "smart" handling of the color parameter
1775 to various methods.
1776 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1777
1778
1779Imager 0.50 - 29 Mar 2006
1780===========
1781
1782 - CRITICAL: fixes a segmentation fault from attempting to write a 2
