DirectX: Loading textures from disk

[VengefulPastry]

I've decided to learn C++. Having come from a Visual Basic/DirectX background, I got used to loading textures from the disk using the "CreateTextureFromFileEx" command.... which was very useful for setting parameters like memory usage and stencil/mask colors...

...unfortunately, C++ DirectX seems not to have a similar command. Does anybody know how to load a texture from disk in C++/DirectX that allows you to program in the extra parameters directly?

Thanks!

Hi,

I believe the function you looking for is D3DXCreateTextureFromFileEx. I guess you just have to stick D3DX infront of the function to covert from VB to C++. Also don't forget to include d3dx8.h or d3dx9.h depending on which version of directx you are using.

Cheers

That was it!

I couldn't find documentation for "d3dxcreatetexturefromfileex" in the DX9 SDK, so I just assumed it wasn't included. That will teach me to assume.

I plugged it in, and the compiler automated adding about 10 extra .cpp and .h files that allowed me to use the texture loader utility.

Thanks Ferdi!

The D3DX library is a very good addition to the DirectX SDK. It saves a lot of time doing common stuff!

D3DX is what keeps me from using...the "Other" graphics API. :)

How true! :D

@VengefulPastry: Are you going to use DX9 for your idie games? That SDK would be only installed at hardcore gamers and not all cards support DX9. I suggest DX7 or DX8(.1).

Hmmmm, good point C_Coder.....

Any idea where to get a copy of the 8.0 SDK? And....I'm on dial-up....

You can develop DX8 (or any previous version) apps using the DX9 SDK (I am doing this currently, and it works perfectly fine).

Just #define DIRECT3D_VERSION to 0x0800 before you include any DX headers. Similar defines exist for the other bits & bobs of DirectX (DSound, etc).

Use Direct3DCreate8 to create an IDirect3D8 interface and IDirect3D8::CreateDevice to create an IDirect3DDevice8 interface.

I do not set that #define to use DX8 since there are these interfaces directly.
