IReadableBitmapDataGetPixel Method

Gets the color of the pixel at the specified coordinates as a Color value.

Definition

Namespace: KGySoft.Drawing.Imaging
Assembly: KGySoft.Drawing.Core (in KGySoft.Drawing.Core.dll) Version: 8.0.0
C#
Color GetPixel(
	int x,
	int y
)

Parameters

x  Int32
The x-coordinate of the pixel to retrieve.
y  Int32
The y-coordinate of the pixel to retrieve.

Return Value

Color
A Color instance that represents the color of the specified pixel.

Remarks

The returned value is a non-premultiplied color with 8 bits per channel in the sRGB color space, regardless of the underlying PixelFormat. The result of the GetColor32 method represents the same range of colors as Color and has a slightly better performance than this method.

Line by line processing is also possible by obtaining the first row by the FirstRow property, getting the pixels by the IReadableBitmapDataRowMovable 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 ReadRaw method.
