Default Allegro Font
Felix-The-Ghost

Hey guys, I searched on the forums first but there were a lot of results about fonts in Allegro.

I'm looking for the font Allegro uses when there's no other font specified -- the pixel-ly one? Where would I find it? I wanted to be able to use it in Photoshop for graphics testing.

Or would that be weird with the set height?

Matthew Leverton

It's in src/font.c.

Is there a font file I can install to use in Photoshop?

Matthew Leverton

It's a hardcoded, fixed bitmap font. It wouldn't even scale.

Just search the Googlewebs for any old school fixed width font if you want an equivalent.

From what I remember it's actually just the 8x8 CGA ROM/BIOS font. Shawn simply ripped it from his computer. Google images seems to confirm:

BIOS font: {"name":"olicga.png","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/a\/9a4fda9c9f943aac7dc080c252b33a42.png","w":256,"h":128,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/a\/9a4fda9c9f943aac7dc080c252b33a42"}olicga.png

A4 font: {"name":"a4_font.png","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/2\/b\/2b18edf383ebca99589c900f3968c605.png","w":257,"h":321,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/2\/b\/2b18edf383ebca99589c900f3968c605"}a4_font.png

I don't care if it scales, I just wanted to be able to type something and get a picture of that. I guess maybe I could just write a program for that. Or continue just taking screenshots :/ I just thought it'd be cool to be able to type it directly where I was editing it (Photoshop)

Or you could do as Matthew suggested and get results like this in a couple of minutes.

I'd bet money you could grab your own computer BIOS font in a few minutes with a DOS compiler, DOSBOX and Ralf Brown's info on memory locations.

[EDIT]

I'm gonna do that right now, time me for the revision time.

Aw, heck, I decided to use tcc and it wouldn't allow inline asm, and bc4 refused to run tlink so I gave up, anyway this should print it to the console, a redirect would work to save it to a file.

#SelectExpand

I don't think you are allowed to call interrupts on most modern systems.

edit: Nevermind, just tried in debug. On windows it seems to work.

Arthur Kalliokoski

That's why I specified using DOSBOX.

amber

Does DJGPP work in DOSBOX? You could always try that.

Arthur Kalliokoski

I didn't want to re-educate myself with mydosptr (?) and all that crap for a show off demo. I should have kept my mouth shut.

Maybe if I copy the bc4 stuff to a proper temporary directory and set the environment correctly it'd work. But I'm too lazy.

[EDIT]

Well I tried it anyway, and the exe prints some stuff and hangs, then crashes DOSBOX.
I tried redirecting to a file, but it's just 0 bytes long. I gotta go visit somebody now.
