The first step is to create a new font with the UDG. Dilwyn's article Fun with Fonts offers a lot of great info about creating and using fonts: http://www.dilwyn.me.uk/docs/articles/funfonts.zip
But calculating byte values is tedious work. Of course, there are a number of font creation programs out there, and my favourite is FontEd. But creating UDGs, pixel by pixel, takes a long time and it's rather dull.
So I created RAW2FONT - a small program that builds a QL font from an image, making it very simple to import font sheets from ZX Spectrum or other old computers.
- The image must be in raw format, have black background, and must use the QL palette
The image must have X by Y rows of chars (last row may not be complete)
Each QL character is defined on a tile of W x H pixel (w is 8 to 16 ; H is 9 to 18, thus alowing to have some space between characters and between rows in the image)
Each QL character is 8x9 pixels, aligned on the left top corner of the tile.
- the basic program
Photoshop QL palette (4 and 8 colors)
Gimp QL Palette (4 and 8 colors)
3 fonts - Noir, Vazio and Zeus - each having the png image, the raw image to be used with the program and the QL font created
