Does the colour pippette in the Edit colour dialogue work correctly in
the BGR modes found on Titanium or IGEPv5 systems? After a bit of
confusion due to some colour coincidences, it looks to me as if it's
selecting the colours with R and B swapped.
Hello Steve
Could you attach a sample document and the RGB value you expect so I can
check on my side on - RPi 1B - RPi 3B - BeagleBoard-xM.
all running RiscOS 5.24
It shouldn't need a sample document: create a new document, open the new
colour dialogue, and try picking colours off the screen using the
pipette/dropper tool.
On older hardware (including those that you mention above), this works as
expected. On machines whose graphics systems swap Red and Blue, the tool
doesn't seem to take this into account.
For a clear example, if you have the colour bar open (Utilities->Show colour
bar), try using the dropper to pick the red colour (100% red in the default
document) and see it appear as 100% blue. Then try the 100% blue colour, and
see it appear as 100% red. Finally, the 100% green colour gets picked
correctly, which is as expected.
But, it will work fine on your hardware. This effect is almost certainly
specific to the Titanium and IGEPv5 boards for now.
