Public Methods

Method Description
Bind ( Microsoft.Xna.Framework.Graphics device, Microsoft.Xna.Framework.Graphics surface, bool update ) : void
Bind ( Microsoft.Xna.Framework.Graphics device, Microsoft.Xna.Framework.Graphics surface, ushort miplevel, bool update ) : void

Call this to associate a Xna Texture2D with this pixel buffer
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.

GenMipmaps ( ) : void

Internal function to update mipmaps on update of level 0
GetRenderTarget ( int slice ) : RenderTexture
XnaHardwarePixelBuffer ( BufferUsage usage ) : System
XnaHardwarePixelBuffer ( int width, int height, int depth, PixelFormat format, BufferUsage usage, bool useSystemMemory, bool useShadowBuffer ) : System

Protected Methods

Method Description
CreateRenderTextures ( bool update ) : void

Create (or update) render textures for slices
DestroyRenderTextures ( ) : void

Destroy render textures for slices
LockImpl ( BasicBox lockBox, BufferLocking options ) : PixelBox

Internal implementation of HardwareBuffer.Lock.
UnlockImpl ( ) : void

Internal implementation of HardwareBuffer.Unlock.
