No. I'm just as clumsy as you.
But I found the mistake. The mouse is exactly over 1 pixel. Now Sean
defines the region that's going to be enlarged:
xmouse-nRect/nZoom,ymouse-nRect/nZoom,;;+
nRect/nZoom*2,nRect/nZoom*2
that's 10 pixel up and left and then 20 pixels down and right, which
gives you a 20x20 pixel section. But 20x20 pixel can't have a center
pixel. Add one pixel right and down and you're set:
xmouse-nRect/nZoom,ymouse-nRect/nZoom,;;+
nRect/nZoom*2+1,nRect/nZoom*2+1
Also the color picking is 100% precise then with:
nColor=win.getpixel(xmouse,ymouse)++" (#"++;;+
fill("000000",case("upper",win.hex(win.getpixel1(xmouse,ymouse))))
++")"
No xmouse-1 anymore.
I think it might be better to define a pixel-radius and a zoom-
factor for the script to avoid rounding mistakes, like a radius of
10 and a zoom factor of 5, which would give you a section of 21x21
and an enlarged picture of 105x105.
Gee, I definitely have to stop posting now, before it becomes my
full-time job.
