Function Documentation

TIFFCleanup()

void TIFFCleanup

(

TIFF *

tif

)

Auxiliary function to free the TIFF structure. Given structure will be completely freed, so you should save opened file handle and pointer to the close procedure in external variables before calling _TIFFCleanup(), if you will need these ones to close the file.

void TIFFClose

(
