Defined in CFbsColor256BitmapUtil:
CopyBitmap(), EFloydSteinberg, ENoDither, NewL(), TDither
Inherited from CBase:
operator new()
static CFbsColor256BitmapUtil* NewL(const CPalette* aPalette);
Description
Allocates and constructs a new 256 colour bitmap utility
object, optionally specifying a palette.
Parameters
const
CPalette* aPalette |
The palette of colours to use for the destination 256 colour
bitmap. If there are more than 256 colours in the palette, only the first 256
are used. May be NULL, in which case the system default 256 colour palette is
used. |
|
Return value
CFbsColor256BitmapUtil* |
The newly constructed object. |
|
TInt CopyBitmap(CFbsBitmap* aColor256Destination,CFbsBitmap* aSource,TDither aDither=ENoDither);
Description
Copies the contents of a source bitmap to a destination 256
colour bitmap. Both bitmaps must be the same size and the destination bitmap's
display mode must be EColor256.
Parameters
CFbsBitmap* aColor256Destination |
The destination to copy the bitmap to. Its display mode must be
EColor256. |
CFbsBitmap* aSource |
The source bitmap to copy from. Its display mode can be
EColor16M, EColor64K, EColor4K or
EColor256. |
TDither aDither=ENoDither |
Specify EFloydSteinberg for Floyd-Steinberg
dithering. By default, no dithering. |
|
Return value
TInt |
KErrNone, if successful; otherwise, another of
the system-wide error codes. KErrNotSupported is returned if
aSource's display mode is not one of the values listed. |
|
Panic codes
EFbsColor256UtilError |
Either aColor256Destination's display mode is not
EColor256, or the two bitmaps are not the same size. |
|
TDither
Description
Indicates whether or not to use dithering.
