Hi guys

As far as I know, Adobe holds patents for both file formats. Do you have any idea if I can safely use ImageEN in a commercial application to save images as PSD or (LZW compressed?) TIF without patent infringement?

Thanks
Uwe

TIFF offers the option of using LZW compression, a lossless data-compression technique for reducing a file's size. Until 2004, use of this option was limited because the LZW technique was under several patents. However, these patents have expired.

I could not find anything on PDF.
