hi,
sort of difficult to understand "along the lines" not sure what that means
but you can create your transparent layer and then do a selection of the area you want... and just paint that area
or you can create a filled area and add a mask and paint mask for what area you want to show thru ..
it would probably help if we could see the image your working and specifics on what your trying to do... keep in mind there a lot of different ways to reach the end results and it depends on the image which is the best route.
