Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Pixes (pix_ objects) Group: any operating system Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: pix_film prints an error msg if frame <0 but not if = 0

Initial Comment: This is a very minor issue, however...

The right inlet of [pix_film] accepts a frame number which ranges from 1 to N if the video has N frames.

If it receives a negative frame number, it prints an error message: error: [pix_film]: selection number must be > 0

To be consistent, it should print the same error message when it receives 0 as the frame number, but it doesn't.

Indeed I thing the condition is actually that the frame be >=1 (consider floats!)

Also I would suggest to specify in the help patch that the frame numbers start from 1 (unless I am the only one who would expect it to start from 0)

Message: i agree that it should be consistent. i also agree that the frames should range from 0..(N-1) rather than 1..N? i even think that for (most?) backends the frame number ranges from 0..(N-1).

does the problem still exist with Gem-0.93?

(minor sidenote: the error message says indeed that the frame number must be ">0" but the check is done whether it is "!<0", so this should be ok)
