I made an editor for setbitmap.

Click on a color on the right to paint with it.
Use Get to copy an array from the clipboard.
Use Put to copy an array to the clipboard.
Single Color means a Get only checks for fore and background color and Put exports 'x' for black in stead of 'b' for use with setbitmap in single color mode. Check / Uncheck it, then do Get / Put.
Ctrl + click or painting with Silver removes a color, makes it transparent.
Shift click will replace all pixels with that color with the current color.
In the lower right you can adjust columns/rows.
When you Get an array and Lock is checked, these dimensions will stay the same, else they will be adjusted to that array.
The latest 'put' will be saved to a file mem.txt.
When importing Single color mode gets set.
An array will look something like this:
"r l",
" ",
" n n ",
" n n ",
" n n ",
" n n ",
" ",
" llll ",
" llll llll ",
" r r ",
" r r ",
" r r ",
" r rr ",
" ffffffff ",
" ",
"a u";
