That's what I wanted! But, I didn't know the question because I didn't know the answer. On 30/05/2018 23:09, Karsten Hilbert wrote: On Wed, May 30, 2018 at 11:01:17PM +0200, Peter J. Holzer wrote: On 2018-05-30 22:08:45 +0200, Paul St George wrote: Ha! No, my question was clumsy. If I

Ha! No, my question was clumsy. If I know the name of the viewer that I want to use (say for example: ‘ImageMagick’), where do I find the argument that should be used in a line of code such as this: ImageShow.register(MyViewer("gwenview"), -1) I want to replace ‘gwenview’ with the name of

Is there, somewhere, a list of viewers and their names (for the purposes of this script)? I am assuming that if I want to ImageMagick (for example), there would be some shorter name - such as 'magick' - and it would be lower case . On 29/05/2018 08:58, Peter Otten wrote: Paul St George

Thank you. You are very right. The show() method is intended for debugging purposes and is useful for that, but what method should I be using and is PIL the best imaging library for my purposes? I do not want to manipulate images, I only want to show images (full screen) on an external
