Properties

	Name	Description
	Bounds	Gets the size of this resource.
	Format	Gets the format of the texture data. (Inherited from Texture.)
	Height	Gets the height of this texture resource, in pixels.
	IsDisposed	Gets a value that indicates whether the object is disposed. (Inherited from GraphicsResource.)
	LevelCount	Gets the number of texture levels in a multilevel texture. (Inherited from Texture.)
	Width	Gets the width of this texture resource, in pixels.

Methods

	Name	Description
	Dispose()	Immediately releases the unmanaged resources used by this object. (Inherited from GraphicsResource.)
	Dispose(Boolean)	Immediately releases the unmanaged resources used by this object. (Inherited from GraphicsResource.)
	Finalize	Allows this object to attempt to free resources and perform other cleanup operations before garbage collection reclaims the object. (Inherited from GraphicsResource.)
	SetData<T>(array<T[])	Sets 2D texture data.
	SetData<T>(array<T[], Int32, Int32)	Sets 2D texture data, specifying a start index, and number of elements.
	SetData<T>(Int32, Nullable<Rectangle>, array<T[], Int32, Int32)	Sets 2D texture data, specifying a mipmap level, source rectangle, start index, and number of elements.

Remarks

A texel represents the smallest unit of a texture that can be read from or written to by the GPU. A texel is composed of 1 to 4 components. Specifically, a texel may be any one of the available texture formats represented in the SurfaceFormat enumeration.

A Texture2D resource contains a 2D grid of texels. Each texel is addressable by a u, v vector. Since it is a texture resource, it may contain mipmap levels.
