Programmatically converting PNG to TIFF

Hi all,

Usually NSImage should be able to read PNG. I found a hint on the net that WindowMaker (libwrster) should be installed before configuring GNUstep to make it PNG aware. I tried that with no success. NSImage ist still not able to read PNG data.

I am now looking for an alternative approach. I have ImageMagick installed. Does anybody now how one can programmatically convert PNG data to TIFF data with ImageMagick so that I can provide NSImage with a TIFFrepresentation? I have the data in the database so a method reading from a file is not suitable.

Thanks a lot!
