Hi folks,

I'm feeling lazy ...

I don't suppose anyone has code I could "steal" for obtaining "bold" text on the VGA output using one of the standard fonts, e.g. FONT 1, without having to generate an external font file.

I guess the routes are:

1. Overprinting slightly offset with a transparent background ?

2. Generating the new font in-memory with PEEK and POKE.

Best wishes,

Tom

Overprinting with single pixel offsets works nicely, especially with the larger fonts. Your choice of how many overstrikes, and whether you do x only or x and y.

You can also overprint with single pixel offsets, varying the font colors from back to front, to give a shadowed effect.

LOL, I was just literally going to say I had found that ;-)
