The L_JP2_JPXCOMPOSITE structure provides information for compositing layers contained in a JPEG 2000 file.
typedef struct _tagL_JP2_JPXCOMPOSITE
{
L_UINT32 uStructSize;
pL_JP2_JPXBITMAPS pBitmaps;
L_UINT32 uNumOfBitmaps;
} L_JP2_JPXCOMPOSITE, *pL_JP2_JPXCOMPOSITE;
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
Array of compositing layers information.
Number of compositing layers. This field specifies the array size.
A JPEG 2000 file may have multiple compositing layers, each with its own color, opacity, and pre-multiplied opacity channels. If any of a layer's bitmaps is not allocated, the layer has no channel of this type.
