You should add a function for a bitmap image to be converted, and then a "selection window" like a sort of cropping tool for the size of the pic on a calc, then it makes that into a picture based on the user decided area.That's something that I actually overlooked. Good call on that, that should definitely be in there.
And just for the heck of it, take that pic and turn it into hex, I have thoughts of doing that for FFME, but a Pic is huge, and it would take forever.Given what I already have implemented, that's easy enough to do, so I'll go ahead and throw that in there. I'll also add a feature to insert a hex sprite, so that you can click on the screen, it'll prompt you for some hex, and then it'll put it in there.
I've worked on it some more, here's what I've got. These are just some of the shapes that you'll be able to add. There will also be the ability to toggle a grid and set the size (so the grid can be every 8x8 pixels, etc.):
There is also undo/redo.
