PNG3 support in MetaImage

MetaImage

Hi :wave:
What’s the current status of PNG 3 spec support? Is it possible to add EXIF metadata to PNG files? If not, is there a plan to resolve it?

Hello,

Thanks for reaching out!

Currently, MetaImage relies primarily on CoreGraphics (Apple’s framework) and ExifTool for metadata handling. At this time, neither CoreGraphics nor ExifTool supports embedding EXIF metadata into PNG files, as the PNG 3 specification is still very new and not widely adopted in toolchains.

Once support for PNG 3 and its metadata features is integrated into either CoreGraphics or ExifTool, MetaImage will naturally follow and add support as well.

Best regards
