Description

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

uDataSize

The size of the transformed data.

Comments

The Binary filter box allows a portion of the file to be further compressed or encoded (i.e. encrypted). This box is defined in JPX and above file formats. A JPEG 2000 file may contain zero or more Binary Filter boxes.

The L_JP2_BINARYFILTER_BOX structure is used in the following functions:

LJp2FileFormat::ReadBox

LJp2FileFormat::AppendBoxes

LJp2FileFormat::ReadBoxMemory

LJp2FileFormat::AppendBoxesMemory

LJp2FileFormat::FreeBoxes

LJp2FileFormat::GetBoxes

LJp2FileFormat::SetBoxes
