Imager release history. Older releases can be found in Changes.old
+ - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
+ internals, those names only matter for the XS interface.
+
+ - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
+ the API level compiled into a loadable module such as
+ Imager::File::GIF doesn't match that of Imager. Previously it
+ could be difficult to determine exactly which module was failing to
+ load.
+ https://rt.cpan.org/Ticket/Display.html?id=77173
+
+ - The size of rotated images is no longer rounded up so aggressively.
+ Added rounding to the linear interpolation done for rotate() and
+ matrix_transform() for 1 and 3 channel 8-bit images.
+ Adjusted the two tranlate matrices used to build the final rotation
+ matrix to use the distance between the outlier pixels rather than
+ the pixel dimensions (ie. dimension-1).
+ With all of this the output of rotate(degrees => 270) on an 8-bit
+ image exactly matches the output of rotate(right => 270).

+
+Imager 0.90 - 30 Apr 2012
+===========
+
+Bug fixes:
+
+ - Imager::Test::is_imaged() attempted to process an "epsilon"
+ parameter but the prototype didn't allow for the extra parameter.
+ Corrected the prototype.
+
+ - when downconverting samples (eg. from floating point to 8 bit)
+ Imager now rounds the sample value rather than attempting to
+ allocate input values over output values equally. The old
+ behaviour had the probably surprising effect of converting a
+ floating point 2.1/255.0 into an 8-bit 3 rather than the expected
+ 2.
+ This may result in slightly different 8 or 16-bit output images.
+
+ - BI_BITFIELD BMP images were handled incorrectly, both in
+ incorrectly calculating the space required for the masks and in
+ processing the image data itself.
+ https://rt.cpan.org/Ticket/Display.html?id=76736
+
+ - some odd width BMP BI_RLE4 images use run lengths that run one off
+ the edge of the image. Imager now allows this, discarding the
+ extra column.
+
+ - odd length RLE4 runs in BMP images were decoded incorrectly.
+
+ - pkg-config could sometimes return a library that was in a directory
+ EU::MM / $Config{libpth} doesn't know about, but the compiler did.
+ If no -L is included in the pkg-config library information check if
+ EU::MM can find the library, and if not, search our configured
+ directories and insert that into the library flags.
+ https://rt.cpan.org/Ticket/Display.html?id=75869
+
+ - Imager::Probe can now probe for libraries with dependent libraries,
+ common for static linking, eg. libpng requires libz.
+ https://rt.cpan.org/Ticket/Display.html?id=74043
+
+ - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
+
+ - added alternative probe configurations that try to link libz, to
+ handle a statically linked libpng.
+ https://rt.cpan.org/Ticket/Display.html?id=74043
+
+ - if a probe includes testcode, Imager::Probe now checks that code as
+ part of the process of checking each configuration rather than as a
+ post test of the found configuration. This allows alternate
+ configurations to be checked if a matching but non-working
+ configuration is found.
+ https://rt.cpan.org/Ticket/Display.html?id=74043
+
+Other changes:
+
+ - when reading or writing images via callbacks, the default callbacks
+ now push an error message indicating that a required callback was
+ called but not supplied.
+ https://rt.cpan.org/Ticket/Display.html?id=76782
+
+ - clarify which callbacks are required for reading and writing TIFF
+ images.
+
+ - improve logging for creation of callback I/O layers.
+
+ - a little more documentation for Imager::Probe.
+
+ - the i_get_file_background() and i_get_file_backgroundf() APIs now
+ return int to indicate whether the i_background tag was found.
+
+ - PNG rework
+ - improve error reporting
+ - add png_interlace, png_bits tags
+ - read paletted images as paletted images, including transparency
+ - read 1 bit greyscale images as a type suitable for other file
+ handlers to write as bilevel
+ - read 16 bit/sample PNG as 16-bit/sample Imager images
+ - write "bilevel" paletted images as 1 bit grayscale images
+ - write paletted images as paletted images
+ - write 16-bit (or higher)/sample images as 16-bit/sample PNG
+ images
+ - improved metadata support

+
+Imager 0.89 - 18 Mar 2012
+===========
+
+Bug fixes:
+
- getpixel(..., type => "float") and the API i_gpixf() have been
broken on paletted images since they were implemented.
https://rt.cpan.org/Ticket/Display.html?id=75258
+Other changes:
+
- links in the METHOD INDEX now point at the method documentation
rather than the heading you can find them under.
