Hi all
I have a big problem with SDL_Image library, when i want to load a "png"
image into surface. In my game that surface need to by transparen
(additionally with transparent that image from e.g. Photoshop).You know what
wham i think about.
I speek in eglish a little ,but i hope you understand me. I’m from Poland
and in my counrty SDL is
a tabu. If anyone can help me ,please respond.
To get an image to become transparent you have to set the colorkey in SDL
for wich color in the image you want to be transparent. (If I’m not
misstaken… was a while ago I used SDL).

I’m going to assume you mean per-pixel alpha and not colourkeyed
transparency.
If you can use the SDL_Image library
(http://www.libsdl.org/projects/SDL_image/) it has native support for
loading PNG files with per-pixel transparency.
Also, I understand the SDL from the cvs repository has a patch applied
that allows it to load 32bpp BMP files so you can get your per-pixel alpha
that way as well, which is helpful if you don’t have the ability to get
SDL_Image on the platform of your choice.
Not exactly. My image is on the screen a and transparent is only color from
PNG(alpha channel). Additionaly whole image (not only one color) must be
half-opaque. I read in archives but i don’t know did problem was resolved.

OMG, I’m also from Poland, and though I have noticed that SDL isn’t as popular as it is in other countries (at least, from my personal experiences), but I wouldn’t say that it’s “tabu”… LOL 
that was a little, uhm, exagarrated

Hmmm, I don’t know it either, but I’ll try to find out, by making poll on one forum… I’ll send here results after a few days.

Ok, so here they are, results of anonymous poll on one polish programming forum:
DirectX: 17 votes, 39%
SDL: 10 votes, 23%
WinAPI: 9 votes, 20%
Allegro: 2 votes, 4%
Other: 2 votes, 4%
I won’t tell you: 2 votes, 4%
GLUT: 1 vote, 2%
GLFW: 0 votes, 0%
There were 43 votes altogether. Results show that SDL definitely isn’t taboo in Poland though there are more popular libraries.

Results of voting are really impressive. I was unaware probably.
Now,in my project everything is more complicated.
After installation of newer version DevCpp whole application (game) works
slowly.
I tried to change from: screen = SDL_SetVideoMode(RESX, RESY, DEPTH,
SDL_FULLSCREEN | SDL_SWSURFACE );
to: screen = SDL_SetVideoMode(RESX, RESY, DEPTH, SDL_FULLSCREEN |
SDL_HWSURFACE );
resx 1024
resy 768
depth 16
I tred also with difrent combinations of: SDL_HWPALETTE , SDL_DOUBLEBUF ,
SDL_ASYNCBLIT and also it does not work correctly. Simply everything is too
slow.
shokran
