IReadableBitmapDataGetColorF Method

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

Definition

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

C#

ColorF GetColorF(
	int x,
	int y
)

VB

Function GetColorF ( 
	x As Integer,
	y As Integer
) As ColorF

C++

ColorF GetColorF(
	int x, 
	int y
)

F#

abstract GetColorF : 
        x : int * 
        y : int -> ColorF

Parameters

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

Return Value

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

Remarks

The returned value is a non-premultiplied color with 32 bits per channel in the linear 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

ObjectDisposedException	This IReadableBitmapData has already been disposed.
ArgumentOutOfRangeException	x is less than zero or is greater than or equal to Width. -or- y is less than zero or is greater than or equal to Height.
