Hello,
I have a Problem, getting nRow, nCol-position on Images with Scrollbars
nRow and nCol are always related to Screen and not to the Image.
For Image-cropping I want to fill 4 Gets with Top, Left, Bottom and Right ( Results from 2 Mouseclicks ).
Top Image
Scrolling to Bottom, the Mouseclicks are returning wrong Values.
Using Images with Size completely visible on Screen, no Problem.
( the Results from 2 Mouseclicks for Top / Teft and Bottom / Right )
The same used, to define the Watermark-position on Mouseclick
( but only works inside the nonscrolled-area )
There are many predefined positions ( all are working fine )
top-left
top-center
top-right
center-left
center
center-right
bottom-left
bottom-center
bottom-right
Best Regards
Uwe
