Leadtools.Workflow.ImageProcessing Namespace : HighQualityRotateActivity Class



Perform high quality rotation on a black and white image.

Object Model

HighQualityRotateActivity Class

Syntax

Visual Basic (Declaration) 
Public Class HighQualityRotateActivity 
   Inherits ImageProcessingBaseActivity
   Implements IComponent, IDisposable 
Visual Basic (Usage)Copy Code
Dim instance As HighQualityRotateActivity
C# 
public class HighQualityRotateActivity : ImageProcessingBaseActivity, IComponent, IDisposable 
C++/CLI 
public ref class HighQualityRotateActivity : public ImageProcessingBaseActivity, IComponent, IDisposable 

Remarks

The HighQualityRotateActivity can be used to perform high quality rotation on a black and white (1 bits/pixel) images in any angle.

Normal rotation activities such as RotateActivity will rotate the image data as is, which may result in less than desired quality due to the limited number of bits/pixel of the image (1 bit). This activity will temporarily convert the image to 8 bits/pixel internally, perform the rotation and then convert the image back to 1 bits/pixel.

This activity only works with a 1 bits/pixel images (a Leadtools.Workflow.Raster.WorkflowImage with WorkflowImage.BitsPerPixel equals to 1), using this activity on any other image type will result in an exception.

This activity does not support signed data images.

For more information, refer to Cleaning Up 1-Bit Images.
