nn::jpeg::CTR::JpegMpDecoder::GetLastDateTimePointer Member Function#include <nn/jpeg.h> const char * GetLastDateTimePointer() const;
None.
NULL on failure. Gets a string pointer to the timestamp (time of capture) of the image that was either decoded or had Exif information extracted immediately prior to this call.
If that processing fails, this function also fails. This function needs image data to get the information. Do not destroy the image data. This information is the information registered in the IFD0 DateTime tag.
This function fails if the string is not 0-terminated. The size of the data is DATE_TIME_SIZE (20) bytes.
The date and time are obtained as a string with the format "YYYY:MM:DD HH:MM:DD" terminated with 0x00 (20 characters in total).
If the obtained pointer is used to change the timestamp of the image data, then the timestamp obtained from GetLastDateTime is the modified value.
