## siImageDataType

### Introduced

v6.0

### Description

Specifies the different pre-defined data types available for Framebuffers and writable image sources. These image datatypes are not an exhaustive list but only a list of currently known shorthands. Each rendering engine may provide its own set of image data types in addition to the ones listed here.

### C# Syntax

    StringModule.siImageDataTypeRGBA                                            // RGBA
    StringModule.siImageDataTypeRGB                                             // RGB
    StringModule.siImageDataTypeRGBE                                            // RGBE
    StringModule.siImageDataTypeAlpha                                           // Alpha
    StringModule.siImageDataTypeIntensity                                       // Intensity
    StringModule.siImageDataTypeDepth                                           // Depth
    StringModule.siImageDataTypeNormal                                          // Normal
    StringModule.siImageDataTypeMotion                                          // Motion
    StringModule.siImageDataTypeVector                                          // Vector
    StringModule.siImageDataTypePoint                                           // Vector
    StringModule.siImageDataTypeLabel                                           // Label
    StringModule.siImageDataTypeBitMask                                         // BitMask

Constant | Value | Description
--- | --- | ---
siImageDataTypeRGBA | RGBA | Represents a four channel RGB color image, where the fourth channel is the alpha matte.
siImageDataTypeRGB | RGB | Represents a three channel, RGBA color image.
siImageDataTypeRGBE | RGBE | Represents a four channel, RGB color image, where the fourth channel is an exponent. Used for HDR images.
siImageDataTypeAlpha | Alpha | Represents a single channel, alpha matte image.
siImageDataTypeIntensity | Intensity | Represents a single channel, grayscale intensity image.
siImageDataTypeDepth | Depth | Represents a single channel, depth value image.
siImageDataTypeNormal | Normal | Represents a three channel, vector image composed of normalized vectors.
siImageDataTypeMotion | Motion | Represents a three channel, motion vector image.
siImageDataTypeVector | Vector | Represents a three channel image composed of arbitrary vectors.
siImageDataTypePoint | Point | Represents a three channel image composed of arbitrary points in space.
siImageDataTypeLabel | Labels | Represents a single channel, object label image.
siImageDataTypeBitMask | BitMask | Represents a single channel, single bit-mask image.
