1Imager release history. Older releases can be found in Changes.old
2
14a4ea18 3 - NOTE: possibly backward incompatible:
3dcf7595
TC
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
14a4ea18 10 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
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

81Imager 0.93 - 15 Oct 2012
82===========
83
84Bug fixes:
71fbe41a
TC
85
86 - previously a transparency enabled GIF write (the default) would
87 always use a GIF89a header even if none of the images were
88 transparent.
7a5f7bc6 89
b2f967ef
TC
90 - previously the probe step for freetype-config would fail on cygwin

93 https://rt.cpan.org/Ticket/Display.html?id=79922
94
95 - remove the 16-bit/sample limitation from the documentation for
96 setsamples(), it hasn't applied for many releases.
97 https://rt.cpan.org/Ticket/Display.html?id=79989
98
9673d97e
TC
99 - don't copy setsamples() data parameter, it may be a large scalar

TC
109Enhancements:
110
111 - support for giflib 5.0. (5.0.1 and later)
112 https://rt.cpan.org/Ticket/Display.html?id=79029
113 The giflib API Imager uses doesn't have a mechanism to set the
114 header version in 5.0.0.
115
116 - update the GIF library probe code to check for the new giflib 5.0.1
117 EGifSetGifVersion() function, and to check for the giflib 4.2.0
118 uninitialized gif89 bug.
119 https://rt.cpan.org/Ticket/Display.html?id=79679
120 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
121
122 - avoid static variables when capturing IPTC data from JPEG files
123
124 - match Imager::Font;:T1's error message translations to those from
125 later versions of T1Lib.
126
127 - for libtiff versions that support extended warning handlers (3.8.0
128 or later), use them to avoid some global variables.
129
130 - note Image::ExifTool for better metadata support.

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

145===========
146
ef84bb32 147Bug fixes:
38742a13 148
289d65f4
TC
149 - The size of rotated images is no longer rounded up so aggressively.
150 Added rounding to the linear interpolation done for rotate() and
151 matrix_transform() for 1 and 3 channel 8-bit images.
152 Adjusted the two tranlate matrices used to build the final rotation
153 matrix to use the distance between the outlier pixels rather than
154 the pixel dimensions (ie. dimension-1).
155 With all of this the output of rotate(degrees => 270) on an 8-bit
156 image exactly matches the output of rotate(right => 270).
157 https://rt.cpan.org/Ticket/Display.html?id=77063
158
ef84bb32
TC
159Other changes:
160
161 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
162 internals, those names only matter for the XS interface.
163
164 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
165 the API level compiled into a loadable module such as
166 Imager::File::GIF doesn't match that of Imager. Previously it
167 could be difficult to determine exactly which module was failing to
168 load.
169 https://rt.cpan.org/Ticket/Display.html?id=77173
170
171 - added Imager->check_file_limits() as an interface to the
172 i_int_check_image_file_limits() API.
173
174 - Imager->set_file_limits(reset => 1) now resets the limits to the
175 defaults rather than setting them all to unlimited.
176
177 - wrote a brief security note as Imager::Security
178 https://rt.cpan.org/Ticket/Display.html?id=68910
179
6f31dd14 180Imager 0.90 - 30 Apr 2012
7c4464f5
TC
181===========
182
183Bug fixes:
184
185 - Imager::Test::is_imaged() attempted to process an "epsilon"
186 parameter but the prototype didn't allow for the extra parameter.
187 Corrected the prototype.
188
29b38678
TC
189 - when downconverting samples (eg. from floating point to 8 bit)
190 Imager now rounds the sample value rather than attempting to
191 allocate input values over output values equally. The old
192 behaviour had the probably surprising effect of converting a
193 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
194 2.
195 This may result in slightly different 8 or 16-bit output images.
196
e2a86bac
TC
197 - BI_BITFIELD BMP images were handled incorrectly, both in
198 incorrectly calculating the space required for the masks and in
199 processing the image data itself.
200 https://rt.cpan.org/Ticket/Display.html?id=76736
201
202 - some odd width BMP BI_RLE4 images use run lengths that run one off
203 the edge of the image. Imager now allows this, discarding the
204 extra column.
205
206 - odd length RLE4 runs in BMP images were decoded incorrectly.
207
82eb0687
TC
208 - pkg-config could sometimes return a library that was in a directory
209 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
210 If no -L is included in the pkg-config library information check if
211 EU::MM can find the library, and if not, search our configured
212 directories and insert that into the library flags.
213 https://rt.cpan.org/Ticket/Display.html?id=75869
214
de50f459
TC
215 - Imager::Probe can now probe for libraries with dependent libraries,
216 common for static linking, eg. libpng requires libz.
217 https://rt.cpan.org/Ticket/Display.html?id=74043
218
219 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
220
221 - added alternative probe configurations that try to link libz, to
222 handle a statically linked libpng.
223 https://rt.cpan.org/Ticket/Display.html?id=74043
224
225 - if a probe includes testcode, Imager::Probe now checks that code as
226 part of the process of checking each configuration rather than as a
227 post test of the found configuration. This allows alternate
228 configurations to be checked if a matching but non-working
229 configuration is found.
230 https://rt.cpan.org/Ticket/Display.html?id=74043
231
9d5ff8a6
TC
232Other changes:
233
234 - when reading or writing images via callbacks, the default callbacks
235 now push an error message indicating that a required callback was
236 called but not supplied.
237 https://rt.cpan.org/Ticket/Display.html?id=76782
238
239 - clarify which callbacks are required for reading and writing TIFF
240 images.
241
242 - improve logging for creation of callback I/O layers.
243
de50f459
TC
244 - a little more documentation for Imager::Probe.
245
594f5933
TC
246 - the i_get_file_background() and i_get_file_backgroundf() APIs now
247 return int to indicate whether the i_background tag was found.
248
1b46057d
TC
249 - PNG rework
250 - improve error reporting
251 - add png_interlace, png_bits tags
252 - read paletted images as paletted images, including transparency
253 - read 1 bit greyscale images as a type suitable for other file
254 handlers to write as bilevel
255 - read 16 bit/sample PNG as 16-bit/sample Imager images
256 - write "bilevel" paletted images as 1 bit grayscale images
257 - write paletted images as paletted images
258 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
259 images
260 - improved metadata support

266Bug fixes:
267
93eab01e
TC
268 - getpixel(..., type => "float") and the API i_gpixf() have been
269 broken on paletted images since they were implemented.

TC
272Other changes:

TC
274 - links in the METHOD INDEX now point at the method documentation
275 rather than the heading you can find them under.
276 https://rt.cpan.org/Ticket/Display.html?id=71495
277
a5919365
TC
278 - Imager (and the bundled dynamic modules) no longer fallback to
279 using DynaLoader if loading via XSLoader fails.
280 For the bundled modules this could hide useful error messages.
281 https://rt.cpan.org/Ticket/Display.html?id=75560
282
335078fc
TC
283 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
284 buffer in the array of allocations, but just stores the filename
285 pointer and line number.

289===========
290
43bef43b
TC
291 - describe how to build libgif etc on OS X in such a way as to be
292 compatible with a fat binary perl (such as the system perl), in
293 README.

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

467 - io_glue I/O buffering re-work:
468
469 - reorganize io_glue to do it's own buffering by default
470
471 - the unbuffered functions are available as i_io_raw_read() (or
472 raw_read() from perl) etc but are not recommended for typical
473 use.
474
475 - use the new i_io_peekn() when checking for file magic to avoid
476 seek, allowing Imager to detect the file type and read the file
477 from an unseekable stream (for formats that don't use random
478 access)
479
480 - added several new I/O layer API functions.
481
482 - fix the TGA performance problem, most noticably on Win32
483 https://rt.cpan.org/Ticket/Display.html?id=70037
484
485 - TIFF now uses wrapper functions of the correct types to avoid casts
486 https://rt.cpan.org/Ticket/Display.html?id=69912
487
488 - the callback IO object did its own buffering, controlled by the
489 maxbuffer parameter supplied to the read() and write() methods.
490 This buffering has been removed, to avoid redundancy with the
491 common io_glue buffering. This also avoids a bug in that code
492 which could rarely pass a zero length to the read callback and
493 then panic about the result.
494
495 - the callback IO object now tests the result of calling the close
496 callback, which should return true for success.
497
498 - the PNM reader did its own buffering. This buffering has been
499 removed to avoid redundancy with the common io_glue buffering.
500
501 - previously the read handlers for fd and callback I/O layers would
502 call the underlying interface (POSIX read or your supplied callback)
503 until it filled the buffer. It now only makes one call.
504
505 - added public constructors for I/O layer objects (see Imager::IO)
506
507 - all core file handlers now use the i_io_foo() wrappers to gain
508 access to buffered I/O rather than calling the I/O layer
509 callbacks directly.
510
511 - all core file handlers now check for error on close.
512
513 - Backward compatibility: if you hava custom file handlers, you can
514 use i_io_write() etc since they're available as macros in older
515 versions of Imager.
516
517 - eliminate the final remnants of io_glue_commit_types().
518
519 - bump IMAGER_API_VERSION, since the above may break assumptions.
520
521 - removed the long unused i_gen_reader() and i_gen_writer() utility
522 functions.

585Development release as a sanity check for the types re-work.
8d14daab
TC
586
587Massive types re-work:
588
589 - the type used internally for pixel co-ordinates and image sizes is
590 now 64-bit on 64-bit platforms (at least sane ones).
591
592 - size_t is now used consistently for memory block sizes.
593
594 - since this changes the binary interface, the Imager API version has
595 been incremented. Any module that uses the API will need to be
596 rebuilt. In most cases that will be enough, but calls to any APIs
597 that take a pointer to image sizes may need source changes.
598
599 - you should be able to create very large images on 64-bit systems,
600 if you have enough memory. Successfully created a 32768 x 49192 x
601 3 channel image, filled with a tiled image and scaled it. The
602 unscaled image was also successfully saved to a JPEG.
603
604 - check the image size before attempting to write BMP, GIF, JPEG,
605 PNG, SGI, TGA, TIFF images.
606
607 - correctly handle reading TGA images over 32767 pixels wide or tall.
608
609Incidental changes:
610
611 - the gif_left and gif_top tags are now clamped to non-negative
612 values when writing a GIF image.
613
614 - removed dead callback read/write code
615
616The default maximum memory size when reading files is now 1G.

1280 defines them with respect to a translucent source and destination.

1340 10.5 and were causing some build problems.
1341 So henceforth Imager uses the dlopen() family of functions, and you
1342 will need version 10.3 or later of OS X.

1647===========

1649This is primarily a bug fix release.
1650
1651Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1652
1653There is one new feature:
1654
1655 - the Win32 font driver now supports UTF8 (RT 22166)
1656 http://www.cpanforum.com/threads/3276
1657 http://rt.cpan.org/Ticket/Display.html?id=22166
1658
1659Several bugs were fixed:
1660
1661 - the string() method would not output the string "0"
1662 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1663
1664 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1665 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1666
1667 - the gif_disposal and gif_user_input tags weren't being read from
1668 the file correctly
1669 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1670
1671 - gif.c was failing to build under MSVC
1672 http://rt.cpan.org/Ticket/Display.html?id=23922
1673
1674 - in some cases strings passed to the string() method were treated as
1675 terminated by NUL (chr 0)
1676 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1677
1678 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1679 that's the default build name for zlib on Win32.
1680 http://rt.cpan.org/Ticket/Display.html?id=23064
1681
1682 - search $Config{incpath} for headers too, which we should have been
1683 doing all along.
1684
1685Win32 font driver fixes:
1686
1687 - the global descent value from bounding box was the wrong sign
1688 http://www.cpanforum.com/threads/3276
1689
1690 - if the first or last glyph overflowed the left or right side of the
1691 advance width they would be clipped
1692
1693
1694Imager 0.54 - 14 Sep 2006
1695===========
1696
1697This is primarily a feature release:
1698
1699 - a new qtype value 'mixing' has been added to the scale()
1700 method. This is faster than 'normal', slower than 'preview'. This
1701 is based on the method used by pnmscale, and seems to produce less
1702 blurry results than normal.
1703 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1704
1705 - the rubthrough() method can now render onto images with an alpha
1706 channel.
1707 http://rt.cpan.org/Ticket/Display.html?id=20678
1708
1709 - the read_multi() method now falls back to calling doing a single
1710 image read via the read() method and write_multi() will now fall
1711 back to calling write() if a single image is supplied. This means
1712 you can simply call the read_multi() or write_multi() functions
1713 without having to check if the type is formatted by that method.
1714 http://rt.cpan.org/Ticket/Display.html?id=19457
1715 http://rt.cpan.org/Ticket/Display.html?id=19458
1716
1717 - the GIF loop extension can now be written. If you don't have
1718 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1719 should upgrade.
1720 http://rt.cpan.org/Ticket/Display.html?id=21185
1721
1722 - getscanline() and setscanline() can now read/write palette index
1723 based data from/to the image for paletted images, by setting type to
1724 'index'.
1725 http://rt.cpan.org/Ticket/Display.html?id=20338
1726
1727 - we no longer hassle you to disable GIF support
1728 http://rt.cpan.org/Ticket/Display.html?id=20687
1729
1730 - minor documentation fixes
1731
1732
1733Imager 0.53 - 26 Jul 2006
1734===========
1735
1736This is a bugfix release.
1737
1738Some test code was left in a code path not covered by the test
1739suite. A test was added to cover this code path and the test code was
1740removed.

1751
1752 - you can now add file format plugins to support new file formats
1753
1754 - add POD coverage tests
1755
1756 - setcolors() and addcolors() now accept color names and so on
1757 instead of requiring Imager::Color objects.
1758 http://rt.cpan.org/Ticket/Display.html?id=20056
1759
1760 - flood_fill() can now fill to a specified border color instead of
1761 just to the area the same color as the seed.
1762 http://rt.cpan.org/Ticket/Display.html?id=19618
1763
1764
1765Bug fixes:
1766
1767 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1768 calculating the advance width.
1769 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1770
1771 - bounding_box for the T1 driver wasn't including leading and
1772 trailing spaces in the bounding box as the other drivers did, it also
1773 produced strange results for empty strings or strings containing only
1774 spaces

1776 - when reading CMYK jpeg images they were being transferred to the
1777 image object as is, producing a four channel image. It only looked ok
