Typedef Documentation

◆ JxlBasicInfo

typedef struct JxlBasicInfo JxlBasicInfo

Basic image information. This information is available from the file signature and first part of the codestream header.

Enumeration Type Documentation

◆ JxlExtraChannelType

Given type of an extra channel.

◆ JxlOrientation

Image orientation metadata. Values 1..8 match the EXIF definitions. The name indicates the operation to perform to transform from the encoded image to the display image.
