G'Day Folks,
I have written a program to draw on a number of layers; the program allows the user to show / hide layers and all that works okay.
What doesn't work is clearing the layer(s).
The layering is implemented by having multiple Timages with the transparent colour set; this works fine - first time around - but doesn't work when "erasing" the existing graphics...
I've attached the project and 2 images to show what I mean; in one image you see a number of coloured polygons; in the other the previous polygons are now black (the "transparent" colour).
Any help / suggestions would be very welcome!
cheers
S.
