Image Filtering Program in C# .NET
With the precise image filtering methods, developers can apply various effects on images with RasterEdge.Imaging.Processing.dll by using entire C# sample codes. This section is designed to guide users to create C# Windows application to add image filtering functions. If you are VB.NET developers, please go to
image filtering for VB.NET. Want to manage image and document in web service and .NET Windows, please have a look at:
general image managing tutorials in web ASP.NET &
process and edit image and document page in .NET Windows project.
- Open Microsoft Visual Studio (2005 or later versions);
- Begin a new project with programming language - Visual C#;
- Add .NET imaging processing DLLs to your Visual C# project;
- RasterEdge.Imaging.Basic.dll
- RasterEdge.Imaging.Processing.dll
- Add following appropriate .NET imaging using statements to the C# application:
using RasterEdge.Imaging.Basic;
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Basic.Codec;
C# Code to Apply Image Processing Filtering
Following four parts demonstrate the clear and precise image filtering applications methods and sample code in C# platform. If you are interested in other image operations of our C# imaging processor, please go to see:

powerful DLLs for image color mode conversion and
C# libraries for image color correction and adjustment.
C# Methods to Add Noise and Antique Effects to Image
Please apply and use following API solutions to your .NET applications to add noise and antique effect to any target image in short time.
public static int FilterNoiseUniform(REImage img);
public static int ApplyAntiqueEffect(REImage img);
C# Code to Add Noise and Antique Effects to Image
Following C# demo code can help you shorten the time of adding noise and antique effect to image page.
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Basic.Codec;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Basic;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public static void AntiqueEffectImageDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
ImageProcessing.ApplyAntiqueEffect(reImage);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
//public static void AddNoseImageDemo()
{
ImageProcessing.filterNoiseUniform(srcImg);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
}
}
Blur and Sharpen Image Methods in C#
Use methods below to work out your own customized image sharpening and blurring applications.
public static REImage ApplyBlur(REImage img);
public static REImage ApplyBlurGaussian(REImage img);
public static REImage ApplyBlurGaussian(REImage img, double sigma);
public static REImage ApplyBlurUniform(REImage img);
public static REImage ApplySharpen(REImage img);
public static REImage ApplySharpenMore(REImage img);
C# Code to Blur and Sharpen Image
Please take following C# demo code as an important aid to blur and sharpen image.
using RasterEdge.Imaging.Basic.Core;
using RasterEdge.Imaging.Basic.Codec;
using RasterEdge.Imaging.Processing;
using RasterEdge.Imaging.Basic;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public static void SharpenImageDemo()
{
string fileName = "c:/Sample.png";
REImage reImage = REFile.OpenImageFile(fileName);
REImage newImage = ImageProcessing.ApplySharpen(reImage);
REFile.SaveImageFile(newImage, "c:/reimage.png", new PNGEncoder());
}
//public static void BlurImageDemo()
{
REImage savaImage = ImageProcessing.applyBlur(openImage);
REImage savaImage = ImageProcessing.applyBlurUniform(openImage);
REImage savaImage = ImageProcessing.applyBlurGaussian(openImage);
REFile.SaveImageFile(reImage, "c:/reimage.png", new PNGEncoder());
}
}
}
