CreateAliasedBitmap(Rectangle)

Helper function. Same as calling CreateAliasedBounds(bounds, true).

public Bitmap CreateAliasedBitmap(Rectangle bounds)

Parameters

bounds Rectangle

Returns

Bitmap

A GDI+ Bitmap that aliases the entire Surface.

CreateAliasedBitmap(RectInt32)

public Bitmap CreateAliasedBitmap(RectInt32 bounds)

Parameters

bounds RectInt32

Returns

Bitmap

CreateAliasedBitmap(bool)

public Bitmap CreateAliasedBitmap(bool alpha)

Parameters

alpha bool

Returns

Bitmap

CreateAliasedBitmap(Rectangle, bool)

Creates a GDI+ Bitmap object that aliases the same memory that this Surface does. Then you can use GDI+ to draw on to this surface. Note: Since the Bitmap does not hold a reference to this Surface object, nor to the MemoryBlock that it contains, you must hold a reference to the Surface object for as long as you wish to use the aliased Bitmap. Otherwise the memory may be freed and the Bitmap will look corrupt or cause other errors. You may use the RenderArgs class to help manage this lifetime instead.

public Bitmap CreateAliasedBitmap(Rectangle bounds, bool alpha)

Parameters

bounds Rectangle

The rectangle of interest within this Surface that you wish to alias.

alpha bool

If true, the returned bitmap will use PixelFormat.Format32bppArgb. If false, the returned bitmap will use PixelFormat.Format32bppRgb.

Returns

Bitmap

A GDI+ Bitmap that aliases the requested portion of the Surface.

Exceptions

ArgumentOutOfRangeException

bounds was not entirely within the boundaries of the Surface

ObjectDisposedException

This Surface instance is already disposed.
