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.
Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
