texture displays improperly
Ok, I decided to get a little into directx again, and I decided to use direct3d for 2d graphics (rather than use direcdraw).
I managed to get things to display just fine with transparency until I went to make a small cursor (17x17 pixels). It looks fine, except there's a square around it! I thought maybe photoshop was playing tricks on me and somehow I had changed the red by 1 or something around the edge. Nope, its the right color (magenta).
So I try to make the image larger and draw something around the outside. Run the program again, cursor looks the same! Hmm, maybe I saved under the wrong name. But I try to draw inside the square and when I run the program again, the inside of the square has changed, but nothing outside has changed!
Here's how I load the texture:
Code:
bool object::LoadTexture(char *fileName, LPDIRECT3DDEVICE9 d3dDevice)
{
//Use a magenta colourkey
D3DCOLOR colorkey = 0xFFFF00FF;
// Load image from file
if (FAILED(D3DXCreateTextureFromFileEx (d3dDevice, fileName, 0, 0, 1, 0,
D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, D3DX_FILTER_NONE, D3DX_DEFAULT,
colorkey, NULL, NULL, &texture)))
{
return false;
}
D3DSURFACE_DESC surfaceDesc;
texture->GetLevelDesc(0, &surfaceDesc);
width = surfaceDesc.Width;
height = surfaceDesc.Height;
return true;
}
And I use a D3DXSprite to display it:
Code:
Sprite->Draw(texture,NULL,NULL,&D3DXVECTOR2(width/2,height/2),rot,&D3DXVECTOR2(x,y),0xFFFFFFFF);
I'll also attach images of what my cursor looks like in photoshop then in the program.
