Creates a CachedBitmap::CachedBitmap object based on a Bitmap object and a Graphics object. The cached bitmap takes the pixel data from the Bitmap object and stores it in a format that is optimized for the display device associated with the Graphics object.
Type: [in] Bitmap*
Pointer to a Bitmap object that contains the pixel data to be optimized.
Type: [in] Graphics*
Pointer to a Graphics object that is associated with a display device for which the image will be optimized.
You can display a cached bitmap by passing the address of a CachedBitmap::CachedBitmap object to the DrawCachedBitmap method of a Graphics object. Use the Graphics object that was passed to the CachedBitmap::CachedBitmap constructor or another Graphics object that represents the same device.
The following example creates a CachedBitmap::CachedBitmap object based on a Bitmap object and a Graphics object. The code calls the DrawCachedBitmap method of that Graphics object to display the cached bitmap.
VOID Example_CachedBitmap(HDC hdc)
{
Graphics graphics(hdc);
Bitmap bitmap(L"Grapes.jpg");
CachedBitmap cachedBitmap(&bitmap, &graphics);
graphics.DrawCachedBitmap(&cachedBitmap, 10, 10);
}
