Public Methods

Method Description
Bind ( SlimDX.Direct3D9 device, SlimDX.Direct3D9 surface, bool update ) : void

Call this to associate a D3D surface with this pixel buffer
Blit ( Axiom.Graphics.HardwarePixelBuffer src, BasicBox srcBox, BasicBox dstBox ) : void

Copies a box from another PixelBuffer to a region of the this PixelBuffer.

The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions. Only call this function when both buffers are unlocked.

BlitFromMemory ( PixelBox src, BasicBox dstBox ) : void

Copies a region from normal memory to a region of this pixelbuffer. The source image can be in any pixel format supported by Axiom, and in any size.

The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions. Only call this function when both buffers are unlocked.

BlitToMemory ( BasicBox srcBox, PixelBox dst ) : void

Copies a region of this pixelbuffer to normal memory.

The source and destination regions don't have to match, in which case scaling is done. Only call this function when the buffer is unlocked.

ClearSliceRTT ( int zoffset ) : void

Notify TextureBuffer of destruction of render target
D3DHardwarePixelBuffer ( BufferUsage usage ) : System
GenMipmaps ( ) : void

Internal function to update mipmaps on update of level 0
GetRenderTarget ( int zoffset ) : RenderTexture

Get rendertarget for z slice
GetSurface ( Device d3D9Device ) : Surface
LockDeviceAccess ( ) : void
SetMipmapping ( bool doMipmapGen, bool HWMipmaps, SlimDX.Direct3D9 mipTex ) : void

Function to set mipmap generation
UnlockDeviceAccess ( ) : void
