IC0NPRO is a tool that helps users create icons for programs and/or edit existing ones. The inspiration for this program was TIny_Hacker's program Spriter. His program is more thorough and feature-dense but isn't optimized for program icons specifically. You can check out his program here: http://ceme.tech/DL2383
Please see the ReadMe text file for an overview of the program's functions and controls.
Note:
▪This program requires the Celtic CE library to run. If you haven't installed it already, trust me: It's a total game-changer.
▪I have the first version of Spriter on my calculator and have not used any part of its source code in my program. Any similarities between IC0NPRO's source code and Spriter's are purely coincidental.

This looks very impressive. An icon creator is a real game changer.

Thanks! I'm working on an updated version that allows you to import an icon from an existing program directly and replace icons in programs that already have them. I hope to complete it soon.

Nice work on this! It looks well done and I definitely agree that Spriter is lacking a bit in terms of icon creation. I'd recommend linking a download to your program in the topic though, since at first I didn't know it was already available! Have you considered supporting monochrome icons? Not many programs use them on the CE but it could be an interesting thing to consider along with the other planned features you've mentioned.

Also, don't worry about using any stuff from Spriter if you do ever look at the source code later. I will say it's a bit of a mess though so I'm sure what you came up with is probably better

Thanks! I'm glad you don't mind. I wanted to create the topic first because I wanted to include the link in the ReadMe, so I'll add the download link now. I finished adding the new features earlier today and am uploading the updated version now.

When testing version 2, I found 2 small mistakes which I've now fixed. Version 2.1 should be available shortly.

Version 3 is on its way! Thank you EmpireL&N for suggesting the color sidebar thingy (CST).

It appears that many of your screenshots have disappeared.
