I'm too lazy to look into the docs, but maybe the colorvalue is not a

Here follows the link docs link:
http://www.palmos.com/dev/support/docs/palmos/PalmOSReference/Bitmap.html#999107
the documents says:
Transparent color: This should either be a palette index or a direct
color value (an RGB565 value), depending on the bitmap's depth.
I understand that if I am working with a 16-bit image, a need to pass a
rgb565 image.
..and what is a rgb565 image? is a RGB that need to feet the following
rules:
red: from 0 up to 31
green: from 0 up to 63
blue: from 0 up to 31
but the only values that the function is accepting (that do not lead to
the "invalid transparent color" error message) are:
red: 0
green: 0
blue: 0
if you change any value to 1 I get:
"invalid transparent color"
Maybe I am using the wrong struct to pass the values?

Any idea?
