Image problem
Author
I've problems in showing images, I use sprites, and sizes of images changes when showed in screen, what do you suggest? what can I use for this problem, I want to use images for my game menu.
thanks
This is one of the things getting added to the new forum FAQ I believe. See jollyjeffers' Journal, and my reply:
EDIT: You can't quote source code? :/
EDIT2: Ah ha, thanks sirob

Quote:All looks good to me. One thing it might be wortwhile mentioning is that you can use GetLevelDesc() on level 0 to find out the size of the texture D3DX actually created, so you can still use non-power-of-2 textures and just adjust the texture coordinates.
E.g.LPDIRECT3DTEXTURE9 pTexture; // Your texture returned from D3DXD3DXIMAGE_INFO theInfo; // Information about the image D3DX loadedD3DSURFACE_DESC theDesc;if(FAILED(pTexture->GetLevelDesc(0, &theDesc))){ // Error}float tuMax = (float)theInfo.Width / (float)theDesc.Width;float tvMax = (float)theInfo.Height / (float)theDesc.Height;
Then you can render a quad using (tu, tv) as texture coordinates where you'd normally use (1.0f, 1.0f).
Not sure if it fits in here, but I've seen the question on the DX forum 2 or 3 times in the past few weeks.

OK, but what can I do about images? should I use textures and meshes for showing my images for menu and other UI items? currently I'm using D3DXSprite interface and I can't get my images with the desired size, they get bigger or smaller and I can't find a good way to scale them, what's the problem with sprites? Can I use windows API functions in my D3D app?
