Note #2:
Requires the Windows Imaging Component (WIC). WIC is included by default on Windows 7 and above. For Windows XP, WIC is included in SP3, and may be downloaded as a stand-alone component for SP2.

Note #3:
Requires the presence of either (1) video codecs for H.265/HEVC, H.264/AVC and AOMedia AV1, or (2) the HEIF and HEVC extensions from Microsoft. Some versions of Chasys Photo are pre-packaged with basic implementations of these codecs and therefore work out of the box, except in some versions of XP where compatibility issues may arise. A third-party WIC extension for the same may also be used, but at the risk of reduced functionality. The File Associations utility will test your system and indicate which codecs are required if any. For producers of HEIF files, we recommend the use of AV1 (AVIF) over HEVC (HEIC) for the very simple reason that it is not patent-encumbered, and is therefore more likely to gain wide-spread adoption.

Note #4:
Loading of videos is dependent on the video codecs that are available on your computer. Chasys Photo will generally load any video format that you have a codec for. When writing .MOV and .MP$ files, Chasys Photo will use the Motion JPEG codec.

Note #5:
JPEG-XL is still under development and has known issues. As a result of one of these issues, large images cannot be saved in the JPEG-XL format. I also strongly recommend against converting important images to JPEG-XL.

Note #6:
JNG and MNG are rarely used (failed) standards that are only supported for the purpose of migration, and that should not be used for new files. Please consider converting all existing copies to other formats.

Note #7:
Some of the more complex and rarely used features of the MNG standard have been intentionally left out of this implementation. Most files should work fine, though.

Adding More Formats
You can add support for more file formats by installing additional file format plug-ins. If you are comfortable with software development, you can also create your own as described in the Software Development Kit.
