This class enables you to rotate the bitmap on arbitrary angle.

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

Syntax

Visual Basic

Public NotInheritable Class Rotate _
	Inherits BitmapTransform

C#

public sealed class Rotate : BitmapTransform

Remarks

Main parameter of this transform is an Angle specifying how much degrees to rotate the image on. You can also select interpolation algorithm with InterpolationMode property. It specifies how to calculate intermediate points. Different algorithms produces different quality, but as usual the higher quality it produces, the slower algorithm works.

If you need to rotate on 90, 180, or 270 degrees, you should consider using RotateAndFlip transform instead of this one as it works noticeable faster.

Examples

Visual Basic

'Rotate at 5 degrees with medium quality
Dim rotate As New Aurigma.GraphicsMill.Transforms.Rotate
rotate.Angle = 5
rotate.BackgroundColor = Aurigma.GraphicsMill.RgbColor.Yellow
rotate.InterpolationMode = Aurigma.GraphicsMill.Transforms.InterpolationMode.MediumQuality
rotate.ApplyTransform(bitmap)

C#

//Rotate at 5 degrees with medium quality
Aurigma.GraphicsMill.Transforms.Rotate rotate =
    new Aurigma.GraphicsMill.Transforms.Rotate();
rotate.Angle = 5;
rotate.BackgroundColor = Aurigma.GraphicsMill.RgbColor.Yellow;
rotate.InterpolationMode = Aurigma.GraphicsMill.Transforms.InterpolationMode.MediumQuality;
rotate.ApplyTransform(bitmap);
