SDL_ttf: how to: Positioning text

SDL Development
1

Hi, total SDL and OpenGL newbie here. I am using the latest of
everything on WinNT, via the Common Lisp CL-SDL project. Nehe tutorials
up to 5 run great. I have added picking from Nehe-32 successfully, now I
want to add text via SDL_ttf and FreeType.

I have it all installed and am able to open a font and get font and
glyph info, but now it is time to draw text. No sign of it yet. The
picking logic (selecting actually) tells me the glyph is there
somewhere, so that’s a start.

Question: How does one position text in SDL_ttf? glRasterPos?
glTranslatef? Other?

Mind you I find myself wondering if it is not a color issue, since the
selection logic says the glyph is there somewhere. ie, maybe I am
messing up the color info so the character is clear. Anyway, any
ideas/info welcome. Meanwhile I’ll be fussing with the NeHe tutorials to
see if i can at least make win32 fonts and imaging work.–

Well, one of the RenderGlyph methods in SDL_ttf is broken. I think its the
TTF_RenderGlyph_Solid(). For me, it either gives me a memory error or draws
nothing. I think that bug is fixed in the current version in the CVS
repository.

You might want to check out the “glfont” demo that comes with the SDL_ttf.
It shows how to position font and display the text in OpenGL.>I have it all installed and am able to open a font and get font and glyph
