Hello,

 

I am using QuarkXPress on Macintosh to generate EPS Files with Tiff Preview
embedded in it.

I have written some C code to extract Tiff Preview from EPS files generated
which works pretty well.

 

I want do some image manipulation on the extracted tiff images, for which I
intend to use LibTiff on Macintosh. 

The problem right now I am facing is that LibTiff api TIFFOpen returns a
NULL pointer when used with tiff images extracted from 

EPS files, whereas it returns a valid pointer for normal Tiff images.

 

Sample code snippet :

 

TIFF* ptrTiff = TIFFOpen("TiffPreview.tif", "rb");

...

...

 

If(ptrTiff)

            TIFFClose(ptrTiff);

 

Is there any difference between a normal Tiff Image and Tiff Preview Image
Extracted from EPS. 

 

Thanks in Advance !!

 

Regards,
