One Line

This is an art project drawing canvas tool that enables drawing low resolution pixel images. The project includes a file specification for the drawings and a canvas app for making the files.

Dev

I compile and run the .tal file with ../my_projects/run_ui.sh one_line_canvas.tal

The run_ui.sh looks like this:

#!/bin/sh

filename="${1%.*}"
rom_filename="${filename}.rom"

../uxn/bin/uxnasm $1 $rom_filename && ../uxn/bin/uxnemu $rom_filename

Inspect drawing file

To check the data of the drawing manually you can hexdump it. Here you can see the header is correct 58 0a 1f 0a ff 0a.

$ hexdump -C drawing.1line
