Create a C# Console Application

Open Visual Studio and click "New" from toolbar. Note, Visual Studio 2005 and above versions are available ;

Choose "C# Language" and "Console Application" respectively to create a project.

Sample C# Code for Convert Bmp Format to Png Format and Save

By following steps below, your C# project will convert input bmp image file to png file according to priority, and then create a new png file to a defined output path.

Add necessary XImage.Raster DLL libraries into your created C# application as references.




Use namespace "RasterEdge.Imaging.Basic";

Use namespace "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.

Copy of the following C# sample code to your application.

String inputFilePath = Program.RootPath + "\\"  +  "input.bmp";
String outputFilePath = Program.RootPath + "\\"  +  "output.png";
RasterImage img = new RasterImage(inputFilePath);
//Convert format and save.

Sample C# Code for Create WinFroms Application Fast

By following steps below, your C# WinForms project view image.

Open or create a new WinForms application, add “RasterEdge.XImage.Raster.WinFormsControl.dll”to the project’s reference.

Add a new Form Item to the project, and choose to design mode sign. Make the ToolBox view show.

Right click the ToolBox panel, and select “Choose Items…”, in the .NET Framework Components tab of pop-up dialog, click “Browse…”button to navigate the “RasterEdge.XImage.Raster.WinFormsControl.dll”, and make sure the “ImageView”and “ThumbnailView”is checked.

Now the RasterEdge image view control appears in the ToolBox. Just drag and drop the “ImageView”and “ThumbnailView”items to your new Form control.

To make the ThumbnailView connect to the ImageView, add the following code to the Form Initialize method.

public Form1()
     this.thumbnailView1.ThumbImageIndexChanged += new RasterEdge.XImage.Raster.WinFormsControl.ThumbImageIndexChangedEventHandler(thumbnailView1_ThumbImageIndexChanged);
void  thumbnailView1_ThumbImageIndexChanged(object sender,  RasterEdge.XImage.Raster.WinFormsControl.ThumbImageIndexChangedEventArgs e)
     ThumbnailItem item = e.ThumbItem;
     this.imageView1.ShowImage(item, false);
