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.

101Enhancements:
102
103 - support for giflib 5.0. (5.0.1 and later)
104 https://rt.cpan.org/Ticket/Display.html?id=79029
105 The giflib API Imager uses doesn't have a mechanism to set the
106 header version in 5.0.0.
107
108 - update the GIF library probe code to check for the new giflib 5.0.1
109 EGifSetGifVersion() function, and to check for the giflib 4.2.0
110 uninitialized gif89 bug.
111 https://rt.cpan.org/Ticket/Display.html?id=79679
112 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
113
114 - avoid static variables when capturing IPTC data from JPEG files
115
116 - match Imager::Font;:T1's error message translations to those from
117 later versions of T1Lib.
118
119 - for libtiff versions that support extended warning handlers (3.8.0
120 or later), use them to avoid some global variables.
121
122 - note Image::ExifTool for better metadata support.

289d65f4
TC
141 - The size of rotated images is no longer rounded up so aggressively.
142 Added rounding to the linear interpolation done for rotate() and
143 matrix_transform() for 1 and 3 channel 8-bit images.
144 Adjusted the two tranlate matrices used to build the final rotation
145 matrix to use the distance between the outlier pixels rather than
146 the pixel dimensions (ie. dimension-1).
147 With all of this the output of rotate(degrees => 270) on an 8-bit
148 image exactly matches the output of rotate(right => 270).
149 https://rt.cpan.org/Ticket/Display.html?id=77063
150
ef84bb32
TC
151Other changes:
152
153 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
154 internals, those names only matter for the XS interface.
155
156 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
157 the API level compiled into a loadable module such as
158 Imager::File::GIF doesn't match that of Imager. Previously it
159 could be difficult to determine exactly which module was failing to
160 load.
161 https://rt.cpan.org/Ticket/Display.html?id=77173
162
163 - added Imager->check_file_limits() as an interface to the
164 i_int_check_image_file_limits() API.
165
166 - Imager->set_file_limits(reset => 1) now resets the limits to the
167 defaults rather than setting them all to unlimited.
168
169 - wrote a brief security note as Imager::Security
170 https://rt.cpan.org/Ticket/Display.html?id=68910

6f31dd14 172Imager 0.90 - 30 Apr 2012
7c4464f5
TC
173===========
174
175Bug fixes:
176
177 - Imager::Test::is_imaged() attempted to process an "epsilon"
178 parameter but the prototype didn't allow for the extra parameter.
179 Corrected the prototype.
180
29b38678
TC
181 - when downconverting samples (eg. from floating point to 8 bit)
182 Imager now rounds the sample value rather than attempting to
183 allocate input values over output values equally. The old
184 behaviour had the probably surprising effect of converting a
185 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
186 2.
187 This may result in slightly different 8 or 16-bit output images.
188
e2a86bac
TC
189 - BI_BITFIELD BMP images were handled incorrectly, both in
190 incorrectly calculating the space required for the masks and in
191 processing the image data itself.
192 https://rt.cpan.org/Ticket/Display.html?id=76736
193
194 - some odd width BMP BI_RLE4 images use run lengths that run one off
195 the edge of the image. Imager now allows this, discarding the
196 extra column.
197
198 - odd length RLE4 runs in BMP images were decoded incorrectly.
199
82eb0687
TC
200 - pkg-config could sometimes return a library that was in a directory
201 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
202 If no -L is included in the pkg-config library information check if
203 EU::MM can find the library, and if not, search our configured
204 directories and insert that into the library flags.
205 https://rt.cpan.org/Ticket/Display.html?id=75869
206
de50f459
TC
207 - Imager::Probe can now probe for libraries with dependent libraries,
208 common for static linking, eg. libpng requires libz.
209 https://rt.cpan.org/Ticket/Display.html?id=74043
210
211 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
212
213 - added alternative probe configurations that try to link libz, to
214 handle a statically linked libpng.
215 https://rt.cpan.org/Ticket/Display.html?id=74043
216
217 - if a probe includes testcode, Imager::Probe now checks that code as
218 part of the process of checking each configuration rather than as a
219 post test of the found configuration. This allows alternate
220 configurations to be checked if a matching but non-working
221 configuration is found.
222 https://rt.cpan.org/Ticket/Display.html?id=74043
223

TC
224Other changes:
225
226 - when reading or writing images via callbacks, the default callbacks
227 now push an error message indicating that a required callback was
228 called but not supplied.
229 https://rt.cpan.org/Ticket/Display.html?id=76782
230
231 - clarify which callbacks are required for reading and writing TIFF
232 images.
233
234 - improve logging for creation of callback I/O layers.
235
de50f459
TC
236 - a little more documentation for Imager::Probe.
237
594f5933

238 - the i_get_file_background() and i_get_file_backgroundf() APIs now
239 return int to indicate whether the i_background tag was found.

241 - PNG rework
242 - improve error reporting
243 - add png_interlace, png_bits tags
244 - read paletted images as paletted images, including transparency
245 - read 1 bit greyscale images as a type suitable for other file
246 handlers to write as bilevel
247 - read 16 bit/sample PNG as 16-bit/sample Imager images
248 - write "bilevel" paletted images as 1 bit grayscale images
249 - write paletted images as paletted images
250 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
251 images
252 - improved metadata support

269
a5919365
TC
270 - Imager (and the bundled dynamic modules) no longer fallback to
271 using DynaLoader if loading via XSLoader fails.
272 For the bundled modules this could hide useful error messages.
273 https://rt.cpan.org/Ticket/Display.html?id=75560
274
335078fc
TC
275 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a

294 - note that the generator of the apparently non-DFSG-free postscript
295 in MMOne.pfb is a Debian package.
296
02323e69
TC
297 - setsamples() is now a true complement to getsamples() - it can
298 write 8-bit or floating point samples from a scalar or array
299 reference. This adds i_psamp() and i_psampf() to the C level API.
300
301 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
302 changed to make better use of the typemap, but these aren't part of
303 the perl level API anyway. There were no changes to the C level
304 interfaces to these functions.
305
2a27eeff
TC
306 - getpixel() and setpixel() now accept a mix of scalar and array
307 references for the x and y parameters, and unequal array lengths is
308 no longer an error.

6d5c85a2 455==============
a7e32beb
TC
456
457 - add simple tests for the Imager::Test test_image generators
458
6d5c85a2
TC
459 - io_glue I/O buffering re-work:
460
461 - reorganize io_glue to do it's own buffering by default
462
463 - the unbuffered functions are available as i_io_raw_read() (or
464 raw_read() from perl) etc but are not recommended for typical
465 use.
466
467 - use the new i_io_peekn() when checking for file magic to avoid
468 seek, allowing Imager to detect the file type and read the file
469 from an unseekable stream (for formats that don't use random
470 access)
471
472 - added several new I/O layer API functions.
473
474 - fix the TGA performance problem, most noticably on Win32
475 https://rt.cpan.org/Ticket/Display.html?id=70037
476
477 - TIFF now uses wrapper functions of the correct types to avoid casts
478 https://rt.cpan.org/Ticket/Display.html?id=69912
479
480 - the callback IO object did its own buffering, controlled by the
481 maxbuffer parameter supplied to the read() and write() methods.
482 This buffering has been removed, to avoid redundancy with the
483 common io_glue buffering. This also avoids a bug in that code
484 which could rarely pass a zero length to the read callback and
485 then panic about the result.
486
487 - the callback IO object now tests the result of calling the close
488 callback, which should return true for success.
489
490 - the PNM reader did its own buffering. This buffering has been
491 removed to avoid redundancy with the common io_glue buffering.
492
493 - previously the read handlers for fd and callback I/O layers would
494 call the underlying interface (POSIX read or your supplied callback)
495 until it filled the buffer. It now only makes one call.
496
497 - added public constructors for I/O layer objects (see Imager::IO)
498
499 - all core file handlers now use the i_io_foo() wrappers to gain
500 access to buffered I/O rather than calling the I/O layer
501 callbacks directly.
502
503 - all core file handlers now check for error on close.
504
505 - Backward compatibility: if you hava custom file handlers, you can
506 use i_io_write() etc since they're available as macros in older
507 versions of Imager.
508
509 - eliminate the final remnants of io_glue_commit_types().
510
511 - bump IMAGER_API_VERSION, since the above may break assumptions.
512
513 - removed the long unused i_gen_reader() and i_gen_writer() utility
514 functions.

TC
517===========
518
0c647c9a
TC
519The main changes in the release versus 0.84 are:
520
521 - on 64-bit systems, 64-bit types are consistently used for image
522 dimensions and co-ordinated, and for memory block sizes.
523
524 - handle IFD loops in TIFF files correctly. Previously this would
525 lead to an infinite loop.

547 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate

574Imager 0.84_01 - 8 Aug 2011
575==============
576
577Development release as a sanity check for the types re-work.
8d14daab
TC
578
579Massive types re-work:
580
581 - the type used internally for pixel co-ordinates and image sizes is
582 now 64-bit on 64-bit platforms (at least sane ones).
583
584 - size_t is now used consistently for memory block sizes.
585
586 - since this changes the binary interface, the Imager API version has
587 been incremented. Any module that uses the API will need to be
588 rebuilt. In most cases that will be enough, but calls to any APIs
589 that take a pointer to image sizes may need source changes.
590
591 - you should be able to create very large images on 64-bit systems,
592 if you have enough memory. Successfully created a 32768 x 49192 x
593 3 channel image, filled with a tiled image and scaled it. The
594 unscaled image was also successfully saved to a JPEG.
595
596 - check the image size before attempting to write BMP, GIF, JPEG,
597 PNG, SGI, TGA, TIFF images.
598
599 - correctly handle reading TGA images over 32767 pixels wide or tall.
600
601Incidental changes:
602
603 - the gif_left and gif_top tags are now clamped to non-negative
604 values when writing a GIF image.
605
606 - removed dead callback read/write code
607
608The default maximum memory size when reading files is now 1G.

640 - writing a paletted image to GIF wouldn't always use the colors

1639===========
1640
1641This is primarily a bug fix release.
1642
1643Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1644
1645There is one new feature:
1646
1647 - the Win32 font driver now supports UTF8 (RT 22166)
1648 http://www.cpanforum.com/threads/3276
1649 http://rt.cpan.org/Ticket/Display.html?id=22166
1650
1651Several bugs were fixed:
1652
1653 - the string() method would not output the string "0"
1654 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1655
1656 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1657 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1658
1659 - the gif_disposal and gif_user_input tags weren't being read from
1660 the file correctly
1661 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1662
1663 - gif.c was failing to build under MSVC
1664 http://rt.cpan.org/Ticket/Display.html?id=23922
1665
1666 - in some cases strings passed to the string() method were treated as
1667 terminated by NUL (chr 0)
1668 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1669
1670 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1671 that's the default build name for zlib on Win32.
1672 http://rt.cpan.org/Ticket/Display.html?id=23064
1673
1674 - search $Config{incpath} for headers too, which we should have been
1675 doing all along.
1676
1677Win32 font driver fixes:
1678
1679 - the global descent value from bounding box was the wrong sign
1680 http://www.cpanforum.com/threads/3276
1681
1682 - if the first or last glyph overflowed the left or right side of the
1683 advance width they would be clipped
1684
1685
1686Imager 0.54 - 14 Sep 2006
1687===========
1688
1689This is primarily a feature release:
1690
1691 - a new qtype value 'mixing' has been added to the scale()
1692 method. This is faster than 'normal', slower than 'preview'. This
1693 is based on the method used by pnmscale, and seems to produce less
1694 blurry results than normal.
1695 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1696
1697 - the rubthrough() method can now render onto images with an alpha
1698 channel.
1699 http://rt.cpan.org/Ticket/Display.html?id=20678
1700
1701 - the read_multi() method now falls back to calling doing a single
1702 image read via the read() method and write_multi() will now fall
1703 back to calling write() if a single image is supplied. This means
1704 you can simply call the read_multi() or write_multi() functions
1705 without having to check if the type is formatted by that method.
1706 http://rt.cpan.org/Ticket/Display.html?id=19457
1707 http://rt.cpan.org/Ticket/Display.html?id=19458
1708
1709 - the GIF loop extension can now be written. If you don't have
1710 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1711 should upgrade.
1712 http://rt.cpan.org/Ticket/Display.html?id=21185
1713
1714 - getscanline() and setscanline() can now read/write palette index
1715 based data from/to the image for paletted images, by setting type to
1716 'index'.
1717 http://rt.cpan.org/Ticket/Display.html?id=20338
1718
1719 - we no longer hassle you to disable GIF support
1720 http://rt.cpan.org/Ticket/Display.html?id=20687
1721
1722 - minor documentation fixes
1723
1724
1725Imager 0.53 - 26 Jul 2006
1726===========
1727
1728This is a bugfix release.
1729
1730Some test code was left in a code path not covered by the test
1731suite. A test was added to cover this code path and the test code was
1732removed.

1737===========
1738
1739This is primarily a feature release, but contains a fair few bug
1740fixes, new features:
1741
1742 - ability to read and write MS Windows ICO and CUR files
1743
1744 - you can now add file format plugins to support new file formats
1745
1746 - add POD coverage tests
1747
1748 - setcolors() and addcolors() now accept color names and so on
1749 instead of requiring Imager::Color objects.
1750 http://rt.cpan.org/Ticket/Display.html?id=20056
1751
1752 - flood_fill() can now fill to a specified border color instead of
1753 just to the area the same color as the seed.
1754 http://rt.cpan.org/Ticket/Display.html?id=19618
1755
1756
1757Bug fixes:
1758
1759 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1760 calculating the advance width.
1761 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1762
1763 - bounding_box for the T1 driver wasn't including leading and
1764 trailing spaces in the bounding box as the other drivers did, it also
1765 produced strange results for empty strings or strings containing only
1766 spaces
1767
1768 - when reading CMYK jpeg images they were being transferred to the
1769 image object as is, producing a four channel image. It only looked ok
1770 due to an old still unfixed Photoshop bug. We now convert from the
1771 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1772 http://rt.cpan.org/Ticket/Display.html?id=20416
1773
1774 - reading a CYMK TIFF would result in a 4 channel image, reading any
1775 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1776 result in an error.
1777 http://rt.cpan.org/Ticket/Display.html?id=20415
