Hi all,
recently I've been showed an Ios app where the user could select a rectangular area on a PDF page and have that area tagged for later use.
How could we do the same in B4A?
My first thought went to an overlayed semi-transparend panel that the user should use to determine the area of interest (so this panel should be movable and resizable).
Once ready, a double tap (or other action) would both capture the image beneath the panel and record its coordinates relative to the page (along with page number or whatever) somewhere.
Any suggestions, hints or useful code?
TIA,
Umberto
