Drawing icons with pixels

SDL Development
1

Hello,

I am wondering if I could draw some glyphs,sprites,icons etc. with pixels only (using SDL_gfx pixelRGBA

function)? For example I have some color icon 32x32 pixels which is made in GIMP.So the question is: how

exactly this icon can be drawn in color using only pixels in SDL?

Hi,

if you want to draw icons pixel by pixel, it’s going to be awfully
slow. You’d better create a SDL_Surface from your icon using
SDL_CreateRGBSurfaceFrom function and then use SDL_Blit function to
draw it on screen. I bet you can google many examples of this.

regards,

I’m having a problem under Vista with SDL_SetVideoMode().
It just works fine until I change the DPI under Vista to e.g. 150% (144DPI).
The returned screen in FullScreenmode is centered and it seems to be 150%
of the original size.
Is this behaviour supposed to be so ?
