How can I test images for validity?

Post by grgoffe »

Hi,

I have a rather large number of images but some are broken. Is there a way for me to test these and identify the ones that are broken?

Thanks,

George...

You might try to convert each one. If the return code ("errorlevel" in Windows) is non-zero, or you don't get a resulting image, the input was broken.
