The L_JP2_FRAMEINFO structure provides information for a single JPEG 2000 frame.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
uWidth	Frame image width.
uHeight	Frame image height.
uBitsPerPixel	Frame image bits per pixel.
uNumOfCodeStream	Number of codestreams that generate this frame.
puCodeStream	Array of L_UINT specifies the indices of the needed codestreams to generate this frame. The array size is uNumOfCodeStream.

Comments

The L_JP2_FRAMEINFO structure provides information for a single JPEG 2000 frame. This structure is used within the L_JP2_FILEINFO structure, and it is filled by the LJp2FileFormat::GetFileInfo function.
