Texture2D
Texture2D type (as it exists in Shader Model 4) plus resource variables. This texture object supports the following methods in addition to the methods in Shader Model 4.
| Method | Description |
|---|---|
| Gather | Returns the four texel values that would be used in a bi-linear filtering operation. |
| GatherRed | Returns the red components of the four texel values that would be used in a bi-linear filtering operation. |
| GatherGreen | Returns the green components of the four texel values that would be used in a bi-linear filtering operation. |
| GatherBlue | Returns the blue components of the four texel values that would be used in a bi-linear filtering operation. |
| GatherAlpha | Returns the alpha components of the four texel values that would be used in a bi-linear filtering operation. |
| GatherCmp | For four texel values that would be used in a bi-linear filtering operation, returns their comparison against a compare value. |
| GatherCmpRed | For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their red component against a compare value. |
| GatherCmpGreen | For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their green component against a compare value. |
| GatherCmpBlue | For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their blue component against a compare value. |
| GatherCmpAlpha | For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their alpha component against a compare value. |
| GetDimensions | Gets the resource dimensions. |
| Load | Reads texture data. |
| mips.Operator[][] | Gets a read-only resource variable. |
| Operator[] | Gets a read-only resource variable. |
| Sample | Samples a texture. |
| SampleBias | Samples a texture, after applying the bias value to the mipmap level. |
| SampleCmp | Samples a texture, using a comparison value to reject samples. |
| SampleCmpLevelZero | Samples a texture (mipmap level 0 only), using a comparison value to reject samples. |
| SampleGrad | Samples a texture using a gradient to influence the way the sample location is calculated. |
| SampleLevel | Samples a texture on the specified mipmap level. |
