Blit part of a graphic to background (for use as font-character)

[deetee]

Hi all!

Fonts are a big topic in bennugd. Most *.fnt-files are DOS-fonts and not suitable for bennugd. Using ttf-fonts requires an extra lib.
So I decided to give a graphic-font a try.

I found a font-tool (FONY) which is capable to import ttf-fonts and save it as (one) png-graphic-file. Using a monospace font shows me every ie 16 x-pixel a new character.

How can I cut this part of the whole graphic and put it on the screen? The only function in bennugd which seem capable to blit a rectangular block of a graphic to another is "map_block_copy". My first try with this function didn't work. Maybe that's why I wanted to blit to background (not another graphic)?

Is there another (more efficient) function or can you give me please some code example for map_block_copy?

TIA deetee

There's a tile spiltter example in bennupack, located in the 2- medium exaples directory.
I've looked at the code, an I think it could a solution for your problem.
The program is written by "Pixel" (found that in the source).

Another thing you could try is to make a small conversion utillity, that loads a ttf font,
and outputs a fnt font.

Maybe this works (I found this example in the source tree of the bennu karaoke game)

Code Select Expand


IMPORT "mod_video";
IMPORT "mod_map";
IMPORT "mod_ttf";
IMPORT "mod_say";

PROCESS main();
PRIVATE
int fontid=0;

BEGIN
   set_mode(640, 480, 16, MODE_WINDOW);
   fontid=ttf_loadaa("DejaVuSans-Bold.ttf",48,16,RGB(255,0,0),RGB(0,255,0));
   save_fnt(fontid, "font.fnt");
   unload_fnt(fontid);
END



Please note that I haven't tested both examples myself, but they seem usefull.

That you sais is very complex and is very similar to a tiles engine, you can search information of it.
The theory is very simple but is better insert the image of the text result in a graph of a process because you can destroy the text only killing the process.

Hello all!

Thanks for the hints.

handsource-dyko: I tried your code to use bennu+mod_ttf to convert ttf-fonts to fnt-fonts - and it works (great).
It seems that this solves all my font problems  :) - thank you very much.

you can use fntedit and fntedit32 to do, too. The adventage of fntedit32 is that you can create fnts with alpha colors and shadows.
