Bitmap Class

Encapsulates a bitmap, which consists of the pixel data for a graphics image and its methods and attributes.

Namespace: Microsoft.SPOT
Assembly: Microsoft.SPOT.Graphics (in microsoft.spot.graphics.dll)

Syntax

public sealed class Bitmap : MarshalByRefObject

Remarks

This class cannot be inherited.

The .NET Micro Framework provides the Microsoft.SPOT.Bitmap class for lower-level access, such as animation. For displaying static bitmaps and hyperlinked bitmaps, use the Microsoft.SPOT.Presentation.Controls.Image control.

The .NET Micro Framework currently provides support for the following bitmap types.

  • 1bpp Indexed
  • 24bpp RGB
  • 32bpp RGB
  • 48bpp RGB
  • 16bpp RGB 555 (five bits for each color, one bit unused)
  • 16bpp RGB 556 (five bits each for red and blue, six bits for green)

If you add a bitmap to a resource file, your project must reference the assemblies Microsoft.SPOT.Graphics.dll and Microsoft.SPOT.TinyCore.dll.

If a bitmap is embedded as a resource, and its BitmapImageType is Bmp, then the Bitmap object is read-only, and attempts to modify it will throw an exception. You must make a copy of it using Bitmap.DrawImage, and modify the copy, as shown in the following code:

        Bitmap bmpMyBitmap = Resources.GetBitmap(Resources.BitmapResources.MyBitmap);
        Bitmap bmpCopy = new Bitmap(bmpMyBitmap.Width, bmpMyBitmap.Height);
        // copy the bitmap
        bmpCopy.DrawImage(0, 0, bmpMyBitmap, 0, 0, bmpMyBitmap.Width, bmpMyBitmap.Height);
        // now you may modify the copy using any Bitmap method
        bmpCopy.MakeTransparent(Microsoft.SPOT.Presentation.Media.Color.White);
      

Version Information

Available in .NET Micro Framework version 2.0, 2.5
