C# Class Sparrow.Textures.SubTexture

A SubTexture represents a section of another texture. This is achieved solely by manipulation of texture coordinates, making the class very efficient. Note that it is OK to create subtextures of subtextures.

Public Methods

Method	Description
AdjustPositions ( VertexData vertexData, uint startIndex, uint count ) : void
AdjustTexCoords ( VertexData vertexData, uint startIndex, uint count ) : void
AdjustVertexData ( VertexData vertexData, uint startIndex, uint count ) : void
SubTexture ( Texture texture, Rectangle region = null, Rectangle frame = null, bool rotated = false ) : System	Initializes a subtexture with a region (in points) of another texture, using a frame rectangle to place the texture within an image. If 'rotated' is 'true', the subtexture will show the base region rotated by 90 degrees (CCW). If frame is null, it will use the whole texture.
