How to C#: Rotate Image according to Specified angle

Steps to Rotate image

Load an image with RasterImage object.

Create an image processor with ImageProcess object.

Call the method RotateImage of ImageProcess object to complete the task rotating image.

Save the rotated image to an image file on the disk.

In order to acheive the work, please refer to the following steps.

Install XImage.Raster in C# Project

Add necessary references to your C#.NET project. Right-click the project and select "Add Reference..." to locate and add the following DLLs as project references;

  RasterEdge.Imaging.Basic.dll

  RasterEdge.XImage.Raster.Core.dll

  RasterEdge.XImage.Raster.dll

Use corresponding namespaces;

  using RasterEdge.XImage.Raster;

Note: When you get the error "Could not load file or assembly 'RasterEdge.Imaging.Basic' or any other assembly or one of its dependencies. An attempt to load a program with an incorrect format", please check your configure as follows:

       If you are using x64 libraries/dlls, Right click the project -> Properties -> Build -> Platform target: x64.

       If using x86, the platform target should be x86.

How to Rotate Image

By using the XImage.Raster SDK, you can rotate the image according to the specified angle.

Sample Code (rotate image):

RasterImage img = new RasterImage(@"F:\input.tif");
ImageProcess process = new ImageProcess(img);
//Rotate image, the target angle is 30(clockwise), and the negative value will give you a anticlockwise rotate.
process.RotateImage(30);
//If the input image has multiple frames,>
//it will only rotate the second page of the input tif
process.RotateImage(30, 1);
img.Save(@"C:\output.tif">);
