Data Fields | |
md_frame_header * | header |
void * | extMdData |
uns16 | extMdDataSize |
rgn_type | impliedRoi |
md_frame_roi * | roiArray |
uns16 | roiCapacity |
uns16 | roiCount |
This is a helper structure that is used to decode the md_frame_header. Since the header cannot contain any pointers, we need to calculate all information using only offsets.
Please note the structure keeps only pointers to data residing in the image buffer. Once the buffer is deleted, the contents of the structure become invalid.
void* md_frame::extMdData |
Points directly to ext. metadata within the buffer.
uns16 md_frame::extMdDataSize |
Size of the ext. metadata buffer in bytes.
md_frame_header* md_frame::header |
Points directly to the header within the buffer.
rgn_type md_frame::impliedRoi |
Implied ROI calculated during decoding.
md_frame_roi* md_frame::roiArray |
An array of ROI descriptors.
uns16 md_frame::roiCapacity |
Number of ROIs the structure can hold.
uns16 md_frame::roiCount |
Number of ROIs found during decoding.
