nn::jpeg::CTR::JpegMpDecoder::GetMpImageUidListOffset Member Function

#include <nn/jpeg.h>
static size_t GetMpImageUidListOffset(
     const MpIndex * pIndex
);

	Name	Description
in	pIndex	Specifies the MP Index IFD. To get this ahead of time, use the GetMpIndex function.

If successful, returns the byte offset to the unique ID list for individual images.
Returns 0 on failure.

Gets the byte offset from the starting image to the unique ID list for individual images. This offset is included in the MP Index IFD.

The unique ID list for individual images is an MP format option tag and cannot necessarily be obtained for all images. Use the GetMpImageUidListSize function to get the size of the list in bytes.

The application must confirm whether the region indicated by this obtained byte offset and the byte size obtained from the GetMpImageSize function is a valid region.
