REXPaint: Powerful, User-Friendly ASCII Art Editor
Anything that would preclude one from making a similarly-robust HTML5 (Canvas2D) ASCII editor?Font rendering wouldn't even be required. Static bitmap sprite data in a predefined grid cell layout would suffice. With fore and background color altered via fast pixel manipulation using pre-allocated array buffers. Memory usage, on large canvas areas, might be the only prohibitive issue ;)I use the wonderful Piskel 2D sprite drawing tool. And it can handle sizable frame counts at 1024x1024 resolution.https://www.piskelapp.com/
