Rendering text

SDL Development
1

Hi
nowadays im studying SDL_ttf api…i seem to know we render the text on a new
screen.
In glut ? just call the glRasterPos to give the position and then print the
text easily.Is it possible in SDL not to use any surface for
displaying text?I mean just TTF_Init(); open the font and then
(TTF_RenderText_Solid etc) print the text directly to the raster pos??–
Just say the words , your wish is my command…

Hi,
If the TTF_Render… functions of the SDL_ttf api asks for a SDL_Surface*
argument…you could pass the actual screen. Anyway, SDL always uses a
SDL_Surface for displaying something on screen (I dont know if it is inited
using SDL_OPENGL, but AFAIK…no).

I think you’ll get the answer here (on how to position the text):
http://lazyfoo.net/SDL_tutorials/lesson07/index.php

That example doesn’t use OpenGL, but why would one use OpenGL to
render ordinary text?

Best regards,

i have a splash screen before the game starts with SDL_NOFRAME flag and some
drawings and some text in it.The problem is that i cant locate the window
(its 300 X 300) how to position it?is there a way?
And for text rendering , may the problem be that text is rendered and i cant
see it because of the color of the text surface?
thanks for your help
