I have a program in VIPP that reads a set of TIFF Images from a folder using SCALL,
1390 80 MOVETO (work/tiff_ID_front.tiff) CACHE [1100 425] 0 SCALL
It processes normally for most of the tiff images until it encounters certain TIFFs that case the below error:
VIPP Error: VIPP_corrupted_or_unsupported_image_file
The TIFF images all come from the same source code, and I have compared the file properties and they all use CCITT T.6 Compression. Opening the TIFF in Windows photo viewer also displays the image just fine.
I'm not sure what is causing this issue, but in case displaying the TIFF might not be possible, is there a command in VIPP that can run the SCALL command and check if it fails so that it can display an "Image Not Available" message on the page instead of completely crashing the program?
Things I have tried:
- Using ICALL instead of SCALL gives the same error
- Removing the CACHE keyword also produces the same error
- Opening the TIFF image in Adobe Acrobat and recreating it did solve the issue, however, it increases the size of the TIFF images greatly. (Ex. average size is 9 to 12KB, after Acrobat it becomes around 1,000 to 2,000KB). The process would also have to be done manually to each bad TIFF image the program might encounter
I appreciate the help,
Jo
