D3DXLoadSurfaceFromFile problem

logo.pmb? -> logo.bmp?

You have to create a surface in advance. You are passing a pointer to nothing at the moment.

MySrf isn't created yet. D3DXLoadSurfaceFromFile() requires that the first parameter points to a created surface, which is then filled with the image (And there's no D3DXCreateSurfaceFromFile() which is odd).

Why do you want a surface rather than a texture anyway? Give D3DXCreateTextureFromFile() a look, that might be what you want.

hi

thanks for all of you.

actually i have a very big text that i scroll in the Screen,so load this
big text in textur make DirectX crash,so i can load it in Surface and
ofcourse mske it resident in system memory.

again thank you very much for helping.

I was trying to use D3DXLoadSurfaceFromFile today as well, but it seems like creation of surface prior to loading require knowing the image dimentions, format and probably other info (I gave up after former two). So I use D3DXCreateTextureFromFile() and after obtaining image data simply release that object. Not neat but it work...

I guess that D3DXLoadSurfaceFromFile is useful if you don't want to keep re-creating the surface, e.g. if you're loading different images, but the same size over and over. But I still think the function is a bit stupid.

you can know the size of your image that you want to load by

D3DXIMAGE_INFO SrcInfo;
D3DXGetImageInfoFromFile(yourFilename,&SrcInfo);

then create the surface as

D3D_Device->CreateOffscreenPlainSurface(SrcInfo.Width,SrcInfo.Height,D3DFMT_X8R8G8B8,D3DPOOL_MANAGED ,&MySrf,NULL);

and finally

D3DXLoadSurfaceFromFile(MySrf,NULL,NULL,yourFilename,NULL,D3DX_FILTER_NONE,NULL,NULL);

this work with me.

thanks
