Namespace:

Assembly:

System.Drawing.Common.dll

Source:

CachedBitmap.cs

Represents a device-dependent copy of a Bitmap matching a specified Graphics object's current device (display) settings. Avoids reformatting step when rendering, which can significantly improve performance.

Remarks

CachedBitmap matches the current bit depth of the Graphics's device. If the device bit depth changes, the CachedBitmap will no longer be usable and a new instance will need to be created that matches. If the CachedBitmap was created against Format32bppRgb it will always work.

CachedBitmap will not work with any transformations other than translation.

CachedBitmap cannot be used to draw to a printer or metafile.
