]Bitmap class
Encapsulates a bitmap, which consists of the pixel data for a graphics image and its attributes. A Bitmap is an object used to work with images defined by pixel data.
public class Bitmap : Image

| Clone(Rectangle, PixelFormat) | Creates a copy of the section of this Bitmap defined by Rectangle structure and with a specified PixelFormat enumeration. |
| Clone(RectangleF, PixelFormat) | Creates a copy of the section of this Bitmap defined with a specified PixelFormat enumeration. |
| virtual Dispose() | Releases all resources used by this Image. |
| GetBounds(ref GraphicsUnit) | Gets the bounds of the image in the specified unit. |
| GetFrameCount(FrameDimension) | Returns the number of frames of the specified dimension. |
| GetPixel(int, int) | Gets the color of the specified pixel in this Bitmap. |
| override GetPropertyItem(int) | Gets the specified property item from this Image. |
| GetThumbnailImage(int, int, GetThumbnailImageAbort, IntPtr) | Returns a thumbnail for this Image. |
| LockBits(Rectangle, ImageLockMode, PixelFormat) | Locks a Bitmap into system memory. |
| MakeTransparent() | Makes the specified color transparent for this Bitmap. |
| MakeTransparent(Color) | Makes the specified color transparent for this Bitmap. |
| ReadArgb32Pixels(int[]) | Reads bitmap pixels in ARGB32 format into given array. |
| override RemovePropertyItem(int) | Removes the specified property item from this Image. |
| override RotateFlip(RotateFlipType) | This method rotates, flips, or rotates and flips the Image. |
