Legacy ImageMagick Discussions Archive

When using ImageMagick from the terminal, I see that there is no window created for the processing on the image. On the other hand, if I try to do some image processing via openGL, I need to create a context, which is a window. Is there someway possible to render stuff in openGL without a window, something like what ImageMagick does?

Not sure this is what you want. But if on unix, try

display rose:

Now list click on the image and a GUI menu should open that allows some simple commands.
