Get index range of image files matched by path.
- Parameters
-
pfirst_index pointer to index updated with the first number in the range plast_index pointer to index updated with the last number in the range path path which has to be matched by the image files in the range start_index minimum accepted value for the first index in the range
- Returns
- -1 if no image file could be found
