What do u mean by "clarity"? Color depth or screen resolution? There is an
example in each case:
(1) Color depth, e.g. setting 16-bit color depth:
Bitmap bmp;
UInt32 iDepth = 16;
WinScreenMode( winScreenModeSet,
NULL,
NULL,
&iDepth,
NULL );
WinPaintBitmap( bmp, x, y );
BmpDelete( bmp );
(2) Resolution, e.g. Enable display of high-density bitmap
-> encapsulate the Bitmap with BitmapV3
Bitmap bmp;
BitmapTypeV3 *bmpV3;
// Get bitmap to "bmp"
...
bmpV3 = BmpCreateBitmapV3( bmp, kDensityDouble,
BmpGetBits( bmp ),
NULL );
WinPaintBitmap( (BitmapPtr) bmpV3, x, y );
BmpDelete( bmpV3 );
Of course, you can mix the two cases to give high color-depth and
high-density display.
For high-density display, the device need to support high density.
