C# Raster - Convert Image to Bitmap in C#.NET


Online C# Guide for Converting Image to Bitmap in .NET Application




Overview



RasterEdge XImage.Raster provide convert RasterImage object to Bitmap. Because pixel format can not be supported fully by Bitmap, if the source image is 1bpp, the output bitmap will convert to index8bpp.




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.




Convert Image to Bitmap



By following steps below, your can convert RasterImage to bitmap.


Sample Code (convert single frame image to bitmap):




RasterImage img = new RasterImage("input.jpeg");
Bitmap outputBitmap = img.ToBitmap();




Sample Code (convert multi-frame image to bitmap):




RasterImage img = new RasterImage("input.tiff");
Bitmap[] outputBitmaps = new Bitmap[img.PageCount];
for (int n = 0; n < img.PageCount; n++)
{
   outputBitmaps[n] = img.ToBitmap(n);
}
