nn::jpeg::CTR::JpegMpDecoder::GetLastTwlUserMakerNoteSize Member Function

#include <nn/jpeg.h>
size_t GetLastTwlUserMakerNoteSize() const;

None.

If successful, returns the size of the MakerNote in bytes. Returns 0 on failure.

Gets the size in bytes of the Nintendo DSi application MakerNote of the image that was either decoded or whose EXIF information was extracted immediately previous to this call.

If that processing fails, this function also fails. This function needs the image data to get the information, so do not destroy the image data.

Use the GetLastTwlUserMakerNotePointer function to get a pointer to the MakerNote data.

Success of this function does not guarantee that the image was taken with a Nintendo DSi application.

Use the GetLastUserMakerNotePointer and GetLastUserMakerNoteSize functions to get the CTR application MakerNote.
