Here’s what the AppleScript for zoom in could look like:
property theZoom : 2 ^ 0.125
tell application "Skim"
tell front document
set theScale to scale factor of (get view settings)
set theScale to theZoom * theScale
if theScale > 20 then set theScale to 20
set view settings to {scale factor:theScale, auto scales:false}
end tell
end tell
And for zoom out:
property theZoom : 2 ^ -0.125
tell application "Skim"
tell front document
set theScale to scale factor of (get view settings)
set theScale to theZoom * theScale
if theScale < 0.1 then set theScale to 0.1
set view settings to {scale factor:theScale, auto scales:false}
end tell
end tell
I chose 2^0.125 because then calling it twice does the same as normal zoom in
(which effectively uses 2^0.25).
