I suspect this is either something very basic or unsupported. I want to be able to “tap” a sprite or image and detect the hit based on the visible pixels not the bounding rectangle. Can someone point me in the right direction?
I have searched the forums and the docs in vain for a simple answer.

This is a feature request, not a bug, and would be a good addition to the feature request forum.
At the moment you can implement hit testing by combining several objects, or in your object’s touch listener. The touch listener can explicitly filter the touch events it receives and only respond to some of them depending on their coordinates.
llocal shape = display.newCircle(display.contentCenterX, display.contentCenterY - 100, 100)
shape:setFillColor(200, 100, 50)
shape.name = "circle"
local square = display.newRect(display.contentCenterX, display.contentCenterY - 100, 80, 80)
square:setFillColor(0, 100, 200)
square.name = "square"
local square2 = display.newRect(square.contentBounds.xMin, square.contentBounds.yMin, square.width/2, square.width/2)
square2:setFillColor(200, 100, 50)
square2.name = "mask"
local function listener(event)
-- behave as if there is a hole in part of the square
print (event.target.name)
if event.target.name == "square" and event.x \> square2.contentBounds.xMin and event.x \< square2.contentBounds.xMax
and event.y \> square2.contentBounds.yMin and event.y \< square2.contentBounds.yMax
then
return false
else
print(event.name.. "hit at (" .. event.x .. ", " ..event.y.. ")")
event.target:setFillColor(255,255,255)
return true
end
end
