Obtain de size of a IDirect3DSurface (x-y)

[acomos]

Hello.

My question is simple. I have an IDirect3DSurface9, and I need to get the size (with & height) in pixels of the surface. I don't see any method that directly get this information...

How I can get this data?

Thanks

Is the surface representing a full screen or view port?

UPS!!!

Sorry!... The object that I need to obtain the size is a IDirect3DTexture, not an IDirect3DSurface!

The fact is that seems that the IDirect3DTEXTURE interface don't have a method to obtain the width & height of the texture... :P

Thanks for your interest and sorry for the mistake!

I haven't tried this, but it seems like it should work...

1. Call D3DXSaveTextureToFileInMemory() to save the texture to memory.
2. Call D3DXGetImageInfoFromFileInMemory() to get the image dimensions.

Thanks Mike! I will do it in this manner...

However, it's strange that this information (width, height) seems not accesible directly from the IDirect3DTexture :P...

Thanks another time!

Adri.

IDirect3DTexture9::GetLevelDesc() fills out a D3DSURFACE_DESC structure that contains all kinds of information about the specified level of a texture, including its dimensions.
