void * | data |
uns32 | dataSize |
void * | extMdData |
uns16 | extMdDataSize |
This is a helper structure that is used to decode the md_frame_roi_header. Since the header cannot contain any pointers, PVCAM will calculate all information using offsets from frame & ROI headers.
The structure must be created using the pl_md_create_frame_struct function. 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_roi::data |
Points to the ROI image data.
uns32 md_frame_roi::dataSize |
Size of the ROI image data in bytes.
void* md_frame_roi::extMdData |
Points directly to ext. metadata data within the buffer.
uns16 md_frame_roi::extMdDataSize |
Size of the ext. metadata buffer.
md_frame_roi_header* md_frame_roi::header |
Points directly to the header within the buffer.
