The L_JP2_FILEINFO structure provides information about JPEG 2000 file contents.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
eFormat	JPEG 2000 file format.
Header	Header Boxes Information. It provides information about the existing header boxes in a JPEG 2000 file.
DataRef	Data Reference box information. It provides information about the existing Data Reference box in a JPEG 2000 file.
XML	XML boxes information. It provides information about the existing XML boxes in a JPEG 2000 file.
Free	Free boxes information. It provides information about the existing Free boxes in a JPEG 2000 file.
MPEG7	MPEG-7 boxes information. It provides information about the existing MPEG-7 boxes in a JPEG 2000 file.
MediaData	Media Data boxes information. It provides information about the existing Media Data boxes in a JPEG 2000 file.
DigitalSignature	Digital Signature boxes information. It provides information about the existing Digital Signature boxes in a JPEG 2000 file.
BinaryFilter	Binary Filter boxes information. It provides information about the existing Binary Filter boxes in a JPEG 2000 file.
UUID	UUID boxes information. It provides information about the existing UUID boxes in a JPEG 2000 file.
IPR	Intellectual Property Rights (IPR) box information. It provides information about the existing IPR box in a JPEG 2000 file.
UUIDInfo	UUID Info boxes information. It provides information about the existing UUID Info boxes in a JPEG 2000 file.
Association	Association boxes information. It provides information about the existing Association boxes in a JPEG 2000 file.
DesiredReproduction	Desired Reproduction box information. It provides information about the existing Desired Reproduction box in a JPEG 2000 file.
Composition	Composition box information. It provides information about the existing Association box in a JPEG 2000 file.
CodeStream	Codestream boxes information (contiguous and Fragment table). It provides information about the existing codestream boxes in a JPEG 2000 file. If the codestream box is a Fragment Table box it will be reported again in FragmentTable.
FragmentTable	Fragment Table boxes information. It provides information about the existing Fragment Table boxes in a JPEG 2000 file. Fragment Table box is a codestream that is not represented by a Contiguous codestream box.
uNumOfFrames	The number of frames that exist in the JPEG 2000 file.
pFrames	Frames information. An array provides information about all frames exist within the JPEG 2000 file. The size of this array is uNumOfFrames.

Comments

The L_JP2_FILEINFO structure provides information about JPEG 2000 file contents. It is filled by the LJp2FileFormat::GetFileInfo function.
