The color resolution can be different for the various
areas of the OSD. See the call to SetAreas() in the
skin. For instance
tArea Areas[] = { { x0, y0, x7 - 1, y7 - 1, 4 } };
if (osd->CanHandleAreas(Areas, sizeof(Areas) / sizeof(tArea)) == oeOk)
osd->SetAreas(Areas, sizeof(Areas) / sizeof(tArea));
else {
tArea Areas[] = { { x0, y0, x7 - 1, y3 - 1, 2 },
{ x0, y3, x3 - 1, y4 - 1, 1 },
{ x3, y3, x4 - 1, y4 - 1, 2 },
{ x4, y3, x7 - 1, y4 - 1, 2 },
{ x0, y4, x7 - 1, y7 - 1, 4 }
};
osd->SetAreas(Areas, sizeof(Areas) / sizeof(tArea));
}
tries to set one single area with 4bpp, and if that fails
it splits the whole OSD into 5 separate areas with smaller
bpp values.
