This is what I do.... There is a lot going on here. This function will allow
for the keyboard area. I set the pixelscale to 1 for all devices at startup.
I don't know if other scale factors will affect this function but all one
would need is some constructive multiplies.
function getCardRect
--If ignorekeyboard is true then the rect is the entire card is returned
--If ignorekeyboard is false then....
-- If ShrinkKeyboard is true then the rect of the available real-estate is
returned
-- If ShrinkKeyboard is false then the top of the rect is off screen but the
canvas size is the same if the keyboard was not there.
-- also in this mode the canvas can be shifted by KeyboardOffet pixels.
local r1 , r2 , r3 , r4 , tR2 , tR4 , tRectTemp
--return the rect of this card
if the environment is not "mobile" then
put item 1 of the rect of this card into R1
put item 2 of the rect of this card into R2
put item 3 of the rect of this card into R3
put item 4 of the rect of this card into R4
else -- Mobile
put the screenrect into tRectTemp
if the ignorekeyboard of this stack then
put item 1 of the rect of this stack into R1
put item 2 of the rect of this stack into R2
put item 3 of the rect of this stack into R3
put item 4 of the rect of this stack into R4
else -- Don't Ignore Keyboard
put 0 into R1
put item 3 of the effective working screenrect - item 1 of the
effective working screenrect into R3
if the ShrinkKeyboard of this stack then
put 0 into R2
put item 4 of the effective working screenrect - item 2 of the
effective working screenrect into R4
else -- Shrink Keyboard
put (item 4 of the effective working screenrect - item 2 of the
effective working screenrect) - item 4 of the rect of this stack into R2
put item 4 of the effective working screenrect - item 2 of the
effective working screenrect into R4
if the KeyboardOffet of this stack is not empty and the
KeyboardOffet of this stack is a number then
put (item 2 of the rect of this stack - the KeyboardOffet of
this stack) into tR2
put (item 4 of the rect of this stack - the KeyboardOffet of
this stack) into tR4
if tR2 >= R2 then
put tR2 into R2
put tR4 into R4
end if -- Offset out of range
end if -- Keyboard Offset
end if -- Shrink Keyboard
end if --Ignore Keyboard
end if -- Mobile
return (R1,R2,R3,R4)
end getCardRect

Subject: rect w/ scaleFactor?
When the scaleFactor is set to any value other than 1, there appears to be
no relationship between the stack's rect property and its apparent rect on
screen.
"the effective rect..." doesn't help.
How can I obtain the actual on-screen rect of a stack whose scaleFactor is
set to any value other than 1?
