This release restores compatibility with HHVM 3.21 and HHVM 3.27.

This change introduces some minor fixes:

GIF decoding:

• Fixes the rejection of valid GIF images with block ordering which was not understood.

Indexed-color images:

• Fixes the incorrect treatment of color '0' as transparent when no transparent color is set.

File loading:

• Will now throw an exception rather than raising a warning.

This release incorporates some minor bug fixes:

• BMP output was not correct. #30
• PHP Warnings being raised while reading some valid and invalid PNG images before the image was correctly loaded or rejected. #32

• Documentation changes only

This change is a maintenance release.

The major version has incremented because PHP 8.2+ is now required.

The changes correct issues with deprecated PHP features, and update test tools to more supportable/compatible versions. Testing of pull requests against supported PHP versions is now performed via GitHub actions.

• Adds support for reading BMP file format. Various versions, color depths and compression modes are supported, see docs/ for details.

• Adds support for reading and writing WBMP (Wireless Application Protocol Bitmap) image files.
• Adds support for reading GIF files that use a 'deferred clear code'. On previous versions, the Exception "LZW code table overflow" was thrown when this type of file was read.

This release adds support for using GIF files as input to gfx-php.

If the input file is an animation, then only the first image will be used. #17

This release contains two main changes:

• Adds the ability to read PNG images.
  • The PNG reader is triggered when .png is used as the file extension for input.
  • Transparency is be mixed to a white background.
  • See #16 for known limitations.
• Removes the documentation generator, which was generic enough to be spun off as its own project. See doxyphp2sphinx and this related blog post for usage.

This update adds API documentation to the project, and the new gfx-php name.
