IReadableBitmapDataGetColor64 Method

Gets the color of the pixel at the specified coordinates as a Color64 value.

Definition

Namespace: KGySoft.Drawing.Imaging
Assembly: KGySoft.Drawing.Core (in KGySoft.Drawing.Core.dll) Version: 10.0.0-rc.1

C#

Color64 GetColor64(
	int x,
	int y
)

VB

Function GetColor64 ( 
	x As Integer,
	y As Integer
) As Color64

C++

Color64 GetColor64(
	int x, 
	int y
)

F#

abstract GetColor64 : 
        x : int * 
        y : int -> Color64

Parameters

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

Return Value

Color64
A Color64 instance that represents the color of the specified pixel.

Remarks

The returned value is a non-premultiplied color with 16 bits per channel in the sRGB color space, regardless of the underlying PixelFormat.

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 you can use the ReadRaw method.

Note

See the Examples section of the GetReadWriteBitmapData method for examples.

Exceptions
