public class Bitmap1 : Bitmap, IDisposable, IUnknownInitializes a new instance of the Bitmap1 class.
public Bitmap1(IntPtr nativePtr)nativePtr System.IntPtrThe native pointer.
Creates an Bitmap whose data is shared with another resource.
public static Bitmap1 Create(DeviceContext deviceContext, Surface surface, BitmapProperties1 bitmapProperties)deviceContext DeviceContextan instance of RenderTarget
surface SurfaceAn Surface that contains the data to share with the new ID2D1Bitmap. For more information, see the Remarks section.
bitmapProperties BitmapProperties1The pixel format and DPI of the bitmap to create . The Format portion of the pixel format must match the Format of data or the method will fail, but the alpha modes don't have to match. To prevent a mismatch, you can pass NULL or the value obtained from the {{D2D1::PixelFormat}} helper function. The DPI settings do not have to match those of data. If both dpiX and dpiY are 0.0f, the default DPI, 96, is used.
Creates an Bitmap whose data is shared with another resource.

surface SurfaceAn Surface that contains the data to share with the new ID2D1Bitmap. For more information, see the Remarks section.
Creates a Direct2D bitmap from a pointer to in-memory source data.
public static Bitmap1 Create(DeviceContext deviceContext, Size2L size, DataStream dataStream, int pitch, BitmapProperties1 bitmapProperties)deviceContext DeviceContextan instance of RenderTarget
size Size2LThe dimension of the bitmap to create in pixels.
dataStream DataStreamA pointer to the memory location of the image data, or NULL to create an uninitialized bitmap.
pitch intThe byte count of each scanline, which is equal to (the image width in pixels * the number of bytes per pixel) + memory padding. If srcData is NULL, this value is ignored. (Note that pitch is also sometimes called stride.)
bitmapProperties BitmapProperties1The pixel format and dots per inch (DPI) of the bitmap to create.

The bitmap must have been created with the Read flag specified. The caller should try to unmap the memory as quickly as is feasable to release occupied DMA aperture memory.
