There are already a bunch of existing bitmap tools, but I couldn’t find one that would accept a byte array as input. So, I threw one together using jsfiddle.
This is useful to get a quick preview or make a quick tweak to one of the bitmap assets in a game.
To use it:
- Paste a byte array in the large text box
- Modify the number of columns
- Click on the ‘Go’ button
- As you click on the pixels, the byte array in the large text box changes accordingly
It seems to work fine (for me) using Chrome or Firefox (haven’t tried other browsers).
