This class enables you to crop the image.

Namespace: Aurigma.GraphicsMill.Transforms
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public NotInheritable Class Crop _
	Inherits BitmapTransform

C#

public sealed class Crop : BitmapTransform

Remarks

Crop transform returns pixels which are inside of the cropping rectangle (see Rectangle property). If cropping rectangle "grabs" pixels which are beyond of the image (e.g. rectangle is larger of the image, or its coordinates closer to the edge of the image than width of the rectangle), these pixels are filled with BackgroundColor.

All the coordinates and sizes are measured in units specified with Unit property.

Thread Safety

Static members of this type are safe for multi-threaded operations. Instance members of this type are safe for multi-threaded operations.
