Hi,
I'm trying to write a set of routines to access the display buffer. =
In
order to do this I need to know the display type (Eg RGB565, 555, 444 =
etc)
or the device. This will allow me to select the appropriate blit routine =
and
so on. Below is the routine I'm using to do this. I know it will fail on =
any
devices that have palletised displays, I'll cross that bridge later...=20
Passing in the IBitmap obtained from the display should return the =
correct
type. I only have 1 handset to test on, so does this look like the way =
to
go? I've only tested it on a VX7000 and it reported 565 correctly. Any =
show
stoppers that will cause this to screw up? Am I missing some cunning
GETDISPLAYTYPE() call tucked away in the API somewhere instead?
Regards,
Steven Haggerty.
U8 GetColourFormatFromIBitmap(IBitmap *pBMP)
{
RGBVAL rgb;
NativeColor n;
rgb =3D MAKE_RGB(255,0,255);
n =3D IBITMAP_RGBToNative(pBMP,rgb);
switch (n) {=09
case 0xf81f : return mcPixelFormat_RGB565;
case 0x7c1f : return mcPixelFormat_RGB555;
case 0x0f0f : return mcPixelFormat_RGB444;
case 0xff00ff : return mcPixelFormat_RGB888;
default : return mcPixelFormat_None;
}
}
