1998.10.01 13:33 "TIFF Question about Writing out Photoshop Resources.", by Giancarlo D'Ulisse
Hello,
we are using Version 3.4beta037 of the TIFF Library and I have modified it to read Adobe Photoshop resource information:
#define TIFFTAG_PHOTOSHOPRES 34377
When reading this information TIFFGetField() we do the following:
if (TIFFGetField(tif, TIFFTAG_PHOTOSHOPRES, &resourceLength,
&resourceOffset) && resourceLength) {
// allocate some space here for the read.
TIFFSeekFile(tif, (toff_t) resourceOffset, SEEK_SET);
if (!ReadOK(tif, resourcePtr, resourceLength)) {
....
Everything works fine. The problem I am encountering is how to modify the code to write the same information out. I tried to find a similar case in the library but was unable to. Do I get the current position of the file and then write the data and then write the tag? Is order important with respect to other TAG information (ie. should I only do this last or is it ok to wriite this stuff out at any time)?
Thank you very much for your time.
Sincerely
Giancarlo D'Ulisse
