IWritableBitmapDataSetPixel Method

void SetPixel(
	int x,
	int y,
	Color color
)

Sub SetPixel ( 
	x As Integer,
	y As Integer,
	color As Color
)

void SetPixel(
	int x, 
	int y, 
	Color color
)

abstract SetPixel : 
        x : int * 
        y : int * 
        color : Color -> unit 

Parameters

x  Int32

The x-coordinate of the pixel to set.

y  Int32

The y-coordinate of the pixel to set.

color  Color

A Color value that represents the color to assign to the specified pixel.

The color parameter represents a non-premultiplied color with 8 bits per channel in the sRGB color space, regardless of the underlying PixelFormat. The SetColor32 method works with the same range of colors as this one and has a slightly better performance.

Line by line processing is also possible by obtaining the first row by the FirstRow property, setting the pixels by the IWritableBitmapDataRowMovable members and then moving to the next line by the MoveNextRow method.

To access the actual PixelFormat-dependent raw value obtain a row and use the WriteRaw method.

If the color to be set cannot be represented precisely by the owner IWritableBitmapData, then it will be quantized to a supported color value.
