Class ImageBufferExtensionsSystemDrawing

Contains extension methods for ImageBuffer for interop with the System.Drawing library.

Inheritance
object
ImageBufferExtensionsSystemDrawing
Inherited Members
Namespace: ic4
Assembly: ic4dotnet.System.Drawing.dll
Syntax
public static class ImageBufferExtensionsSystemDrawing
Examples

Since the members are extension methods, they can be called both explicitly and on image buffers directly, as if they were member functions.

To call it as a member function, a using directive has to exist for the ic4 namespace: 

using ic4;

// (...)
// Get image buffer from somewhere
ImageBuffer imageBuffer = GetImageBuffer();
// Create copy in a System.Drawing.Bitmap object
System.Drawing.Bitmap bmp = imageBuffer.CreateBitmapCopy();

Although not preferred, the function can also be called explicitly: 

// Get image buffer from somewhere
ImageBuffer imageBuffer = GetImageBuffer();
// Create copy in a System.Drawing.Bitmap object
System.Drawing.Bitmap bmp = imageBuffer.CreateBitmapCopy(imageBuffer);
