Just an idea I want to get of my rather ample chest.
Graph Pad to Pixelart Program IdeaPurpose/benefits: pixel during blackouts, pixel in antitechno social environments, hard copy backup, pixel over hand sketched guides without needing a tablet or pre-scan, etc.
Requirements: gridded paper, pens/pencils
Input: a scan of a pixelart piece drawn into the grid of a graphpad/grid-paper
Output: a pixel clean, colour clean image file
Desirable characteristics- Be insensitive to guide lines
- Only fill pixels when most of the pixel is covered
Manual Mode- Allow user to place overlaid sampling grid ontop of scan (rotate, translate, scale)
- Select and tweak sampled colours for final palette
- Adjust sampling filter size
- Adjust colour tolerance
- Preview results
Automatic Mode- Automatically determine grid allignment and scale using image processing techniques, from grid lines or from pixel boundaries
- Perhaps locallised grid reallignment to compensate for any paper or print stretching
- Automatically centre sampling points in grid squares
- Automatic difference threshold based colour selection
Manual mode would be a piece of piss to implement.
Automatic mode would be more fiddly but still quite practical.
Does anything like this already exist?
