So DF doesn't use a graphics library to display the character-set?
« on: May 24, 2012, 07:35:21 pm »
Hey guys, I'm just curious... does anyone that knows how these things work, does DF use a graphics library? Or since there is no graphics but just characters then there is no need for one? Then in that case, how does the program get those characters to display on the screen?

Yeah, that's what I don't really understand... did Toady have to code it himself, how the program displays these images? Or is there a library that provides most of this functionality?

It does use a graphics library from what I understand. (At the least, I'd hope so, it be a bit of a bother to start coding your own libraries when there's perfectly fine ones already existing and everone and their dog using it)

It's a tile-based program, with in this case the tiles displaying pictures of letters. So it's still as graphical as other tile-based programs. Thing is though, recently the actual text-text display was turned into truetype display.

Well all but the Legacy version do. I think the legacy version uses a custom blitter.

EDIT: And "printmode: text" (IIRC?) on linux just writes characters to the console.

It's not an embark so much as seven dwarves having a simultaneous strange mood and going off to build an artifact fortress that menaces with spikes of awesome and hanging rings of death.

Graphics part is open-sourced, you can check it at Baughn's github.
