In OpenGL I used to be able to set glColour and it would modulate any
textures I drew to the screen. For a monochrome texture (regardless of
texture format) it essentially meant I could change the colour of the image
on the fly.
Is a feature like this supported in SDL 1.3?
It’s a really helpful feature for things like bit-mapped fonts etc
Yep, see SDL_SetTextureColorMod()On Sun, Sep 6, 2009 at 3:52 PM, GMScribe <ali_lowe at sky.com> wrote:

=( Sadly it seems that Colour Mod isn’t supported by the SDL GDI
implementation.

Well, you can always use the software renderer and if you really want
GDI underneath, you can choose that as the backend renderer.On Mon, Sep 7, 2009 at 5:34 AM, GMScribe<ali_lowe at sky.com> wrote:

I’m afraid that the software render doesn’t work for me, in fact only the
GDI and OGL renderers seem to handle the most basic tasks (d3d will draw a
background but no textures, software renderer is black screen). The OGL
renderer is also successfully handling blending with my code. The two video
drivers im offered are Win32 and Dummy, of course I’m using Win32.
For now I guess I’ll have to look at using a hidden OGL window and blitting
to a GDI one.
Many thanks.

OK… I see the function to read pixels from the renderer was never actually
implemented. Is there a special way to setup the software renderer? How do I
ask it to use GDI or an SDL_Surface as a backend?
Many thanks.
