The RawImageData type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | ChangeFormat | Changes the value of the Format property. This does not change the data. |
| CheckTransparency | CheckTransparency method checks the data of the image for transparent pixels and returns true in case any transparent pixel is find. It also sets the HasTransparency property. |
| CheckTransparencyAndConvertToPremultipliedAlpha | CheckTransparencyAndConvertToPremultipliedAlpha method converts the colors by multiplying the red, green and blue values by alpha value. This produces the pre-multiplied colors. The method also checks the data of the image for transparent pixels and returns true in case any transparent pixel is find. It also sets the HasTransparency property. |
 | CheckTransparentPixels | CheckTransparentPixels returns true when the image data contains transparent pixels (where alpha is less the 1); for fully opaque image false is returned. |
| Clone | Returns a cloned RawImageData with copied data array. |
| ConvertToPremultipliedAlpha | ConvertToPremultipliedAlpha method converts the colors by multiplying the red, green and blue values by alpha value. This produces the pre-multiplied colors. |
| GetBytesPerPixel | Returns number of bytes that is required to store the specified format. The method can get results only for the following formats: R8G8B8A8Unorm, B8G8R8A8Unorm, R8G8B8Unorm, B8G8R8Unorm, R8Unorm. Other formats will throw an exception. |
| GetColor | Returns the color as uint value at the specified position. |
| GetColor4 | Returns the color as Color4 value at the specified position. |
| GetColor4Relative | Returns the color as Color4 value at the specified relative position (x and y should be in range from 0 to 1). |
| GetColorRelative | Returns the color as uint value at the specified relative position (x and y should be in range from 0 to 1). |
| GetFormatProperties | GetFormatProperties sets the hasAlpha, pixelSize and alphaOffset properties from the image format. The method returns false when the format is not known. |
| RemovePremultipliedAlpha | RemovePremultipliedAlpha method converts pre-multiplied alpha colors to non-pre-multiplied colors. This is done when IsPreMultipliedAlpha is not false and when format is B8G8R8A8Unorm or R8G8B8A8Unorm. After that the IsPreMultipliedAlpha is set to false. |
| Resize | Creates a new Data array with new dataLength and updates the Width, Height and Stride properties (Format value is preserved). |
| SetColor | Set the color at the specified position |
| SetColor4 | Set the color at the specified position |
| SetColor4Relative | Set the color at the specified relative position (x and y should be in range from 0 to 1). |
| SetColorRelative | Set the color at the specified relative position (x and y should be in range from 0 to 1). |
| SwapRedAndBlueColors | SwapRedAndBlueColors converts RGBA to BGRA and vice versa. |
