Hi. the 16bpp mode that pi does .. is it 555, or 565, and if 565, can we get it to 555? also does the R<->B swap work on it too?

(RISCOS 16 bit is: top bit opaque, 5bits B, 5 bits G, least significant 5 bits R. it would be useful to be able to get that mode)

Thanks
John

If you use the framebuffer mailbox interface to request 16bpp, you get 565 with Blue as low order bits.

The newer properties mailbox interface has a tag for Set Pixel Order (BGR or RGB).

Hi
Yes.. I know of the pixel order swap. I wasn't clear whether this did
work in 16bit, and also would like to request 555 operation as an
option, as that is the only 16bit variant I can use.

Thanks for the response

John
