C# .NET Application for Image Basic Transformation
We intend to show the brief guide on creating and running a C# Windows project to apply image cropping, rotating, resizing & flipping functions using Visual C# sample class within the mature image processing dll component of our .NET Imaging SDK. If you are VB.NET class developers and end users, please go to
basic image edition and processing applications in VB.NET programming language.
- Open Microsoft Visual Studio 2005, 2008 or 2010 version;
- Begin a new Windows project with programming language - C#.NET;
- Integrate following .NET Imaging DLLs within your Visual C# application;
- RasterEdge .Imaging.Basic.dll
- RasterEdge .Imaging.Processing.dll
- Add and run following appropriate namespace for image basic transformation in the C# project:
using RasterEdge.Imaging.Basic;
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Basic.Codec;

Methods for Image Basic Transformation in C#
Following methods on image basic transformation functions enable users to resize, crop, flip and rotate any image and document page. Within this image editing APIs, users have the abilities to adjust image to designed width & height, get a well cropped canvas, flip image vertical and horizontal direction and rotate image in any degree.
public static int ApplyResize(REImage img, int width, int height);
public static int ApplyCrop(REImage img, int x, int y, int width, int height);
public static int ApplyRotate(REImage img, int deg);
public static int ApplyFlip(REImage img);
public static int ApplyFlipV(REImage img);
C# Code on Image Resizing, Cropping, Flipping & Rotating
C# code below shows how to finish the above mentioned basic image processing operation with the complaint methods.

using RasterEdge.Imaging.Basic.Codec;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Basic;

{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyResize(reImage, 500, 500);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
}
}
//public static void CropImageDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyCrop(reImage, 80, 80, 500, 500);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
//public static void RotateImageDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyRotate(reImage, 50);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
//public static void FilpImageHorizontallyDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyFlip(reImage);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
//public static void FilpImageVerticallyDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyFlipV(reImage);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
RasterEdge .NET Imaging SDK provides dozens of image processing functions in several categories including document processing & cleanup, medical image enhancement, color conversion and correction, noise reduction, image information detection, and more. Developers and end users can build variable .NET applications (including C#.NET, VB.NET, web ASP.NET and .NET Windows Forms) to handle these imaging editing functions. As for the overall image processing operations in C# project, please have a look at:
benefits and features on image processing and manipulation in C# class.
