Very useful, especially the command line version, and source code, thank you :-)
YOUR GUI "Browse files" dialog should DEFINITELY be updated FROM ".png" ONLY, TO: ".apng" AND ".png", for the following reasons: (1) With your GUI, I cannot browse for any files that have the APNG file extension - therefore I CANNOT USE YOUR PROGRAM - because I can't load any of my animated PNG files, which ALL have the APNG file extension. (2) Why not just rename my animated APNG files to PNG? For a VERY GOOD REASON - File Associations... * I have all NON-ANIMATED "PNG" files associated by file extension to open in Irfanview image editor. * I have all ANIMATED "APNG" files associated by file extension to open in Firefox web browser. (3) I know that editing your GUI to include both file extensions is trivial from a technical standpoint, and SHOULD BE DONE FOR ALL USERS' BENEFIT. Thanks in advance for giving this serious consideration. I can't yet give a Rating for your project, because I do NOT want to rename test files simply due to an author omitting very default behavior from his/her GUI. If it's not fixed, I'll use a program that has more complete functionality. Since "0" (Unrated) is not an option, I gave it "1". If you update your GUI, and it becomes more useable, I will evaluate it, and give it a revised Rating - AND my thanks for your responsive handling of my suggestion. Thanks again.
