Hi,

I have two TIF files that come from Photoshop. I get the following error with ImageMagick 6.5.3 when converting to PNG:

Invalid Parameter - MB

What is wrong with the file? Is there a way to send you these files?

We have never seen that exception message. Post a URL to your images and the command you used. We will download them and hopefully reproduce the problem.

Works for us (using ImageMagick 6.5.3-8):

I have figured out my mistake. Yes, it is working. Although it does have warnings.

Thanks for your help.

You can get it to be quiet about such warnings using the -quiet operational flag
