Revision history for Image::Info
2009-07-31 Slaven Rezic <srezic@cpan.org>
Release 1.29
SVG parsing is now done by XML::LibXML::Reader, if available,
otherwise the old XML::Simple-based code is used. Using the
new code is much more memory efficient and faster. The old
module can still be used by setting
@Image::Info::SVG::PREFER_MODULE
Removed deprecation notice.
Bundled Module::Install 0.91.
Ceased a warning in the JPEG parsing code with perl 5.6.x.
Lowered minimum required Perl version to 5.6.0 (There's no
evidence that it does not work with that Perl version).
Ceased warnings when reading PNG files with ztxt (compressed
comment) chunk (RT #28054)
2008-03-30 v1.28 Tels 128 tests
* raise minimum required Perl version to v5.6.2
(it doesn't work on 5.005 anyway, open() with three arguments
is not supported there and I don't have time to rewrite the code
for outdated Perl versions. If you need it to run on 5.005, write
a patch and file a bug report please.)
* fix bug #15167: Incorrect width and height for JPG files
(the fix now keeps the highest value for width/height, instead of
creating an array ref with all the values)
* remove Build.PL (bundle Module::Install 0.71)
2007-12-15 v1.27 Tels 128 tests
* add both main authors to META.yml (does not work yet due to bug
in Module::Install)
* fix bug #30890: [PATCH] Transposed lines in documentation
* fix bug #31165: Add attribute for parsing TIFF images (Thanx Adam Witney!)
2007-09-09 v1.26 Tels 128 tests
* clarify the license by adding "v5.8.8" (otherwise it is quite unclear
which Perl version, release or product the license text refers to)

* fix bug #29243 - Exiftext fields (like UserComment) not parsed correctly
2007-05-25 v1.25 Tels 127 tests

block numbers

files)

* regenerate the stale META.yml file
* fix svg.t failing if no XML::Simple was installed (bug #21166)

* better error message in case SOI is missing in a JPEG
(still no fix for #20183)
* SVG:
+ use the correct MIME type "image/svg+xml"
+ version extraction was broken
+ comments had too much whitespace at front/end (these should be
ignored and not extracted anyway)
* add svg.t
* resize test.jpg and test.png to make dist smaller
* add interlace.png and beef up t/png.t
2006-05-01 v1.21 Tels 96 tests

* fix bug #8193: Adds direct access to the determine_file_format logic
With the following changes:
+ read only 11 bytes to determine file format (tiny.pgm is 11 bytes long)
+ fix provided patch to really work
* fix bug #18147:
+ new TIFF code failed if the system endianness didn't match the TIFF
image endianness - thanx jpo!

+ fix bug #3698 Broken BitsPerSample handling in TIFFs
2006-03-03 v1.18 Tels 61 tests
* fix bug #6558: Image::Info 1.16 -> fails two tests (Thanx jpo!)
+ make string.t use strict, Test::More and simplify it
+ let string.t skip tests if Image::Xpm, Image::Xbm or XML::Simple
are not installed (these would formerly silently fail)
+ Image::Info::XPM and Image::Info::XBM now handle in-memory files better
+ fix also pod_cov.t warnings (was "Image::Info.pm" vs "Image::Info")
* reduce img/test.gif in size, it did eat up 1/3 of the entire dist size
* reducing test.jpg with GIMP reveals a bug in EXIF parsing (not yet fixed)
* MakerNote parsing:
+ add support for Panasonic cameras
+ for the following manufacturers we do not check the camera model, this
gets all cameras, even yet unreleased ones to work:
+ Canon
+ Panasonic
+ Casio
+ Olympus
+ Fujifilm
+ UNDEFINED/ASCII strings from MakeNotes might have wrong length due to
trailing \x00 chars, so we remove them and set the correct length
* update one more URL for EXIF specs
* imgdump uses Data::Dumper (not Data::Dump)
* Install/build:
+ use Module::Install and bundle it, clean Makefile.PL up

e.g. you get now 'width="900" height="800"'
* fix bug #8136: update URL for EXIF standard
* fix bug #8522 - dies at JPEGInterchangeFormatLngth (Thanx srezic@cpan.org)
