Does SDL_SoftStretch support Alpha surfaces for blits…
I use IMG_Load to load a png and want to blit that(alpha) to another
surface(alpha) …
SDL_BlitSurface works just fine but SoftStretch does not
Does SDL_SoftStretch support Alpha surfaces for blits…
no. it’s not officially part of the SDL API

And color-keying would also be fine

doh…
can you please enhance the softstretch function to support alpha surfaces
?!?
Best wishes

i will ask the married man if you are not willing…cause i kind of need
this function coop with alpha…
You do realise that as a programmer you have the ability to “create your
own functions”? You can even take the SDL_SoftStretch function, modify
it and include it in your own code.
Its the code of tomorrow, today!On Thu, May 17, 2001 at 06:01:17AM -0700, Tim ‘PeZ’ Theede wrote:

i certainly do realise it…
but im not in any way enough “trained” with asm that i can do a fast enough
function …(and i dont have the time either)

Here is my zotozoomer code (rotate and zoom with bilinear scaling) for
SDL surfaces that handles alpha channels as well:

OK. I’ll check it and add a test program!
(when I have time)

Tim (and all),

I’ve updated the package - it includes build scripts and a demo program
now (spinning SDL logo). Doesn’t crash here!?

I will try it… at first sight … the problem perhaps could be that im
using pngs…

For me, testrotozoom.c doesn’t crash. As read in README ;-), I suggest you
to add the stuff from src/video/SDL_stretch.c (only stretching of surfaces),
this could be a speedup.
