I'm sitting here making my own zoom tool when I start thinking
someelse *must*have done this an a lot better than me.
I have an image with this script
and a slider with this script....
where the gWidth and gHeight are the size of the image after import...
Now the original images are over 3000 pixels wide and 300 DPI..
I need to the user to be able to really zoom in and get a good quality
view of small characters
This works, but I would like to keep the relative position but of course
I am losing this by resetting the topleft to 0,0 each time.
years ago I though there was a widget right in the IDE that was a zoom
tool and you could clone this for your own work...
ideally you the user has the normal experience of switching to a zoom
tool dragging and focusing in on he area of choice..
Can you share?
set the resizequality of image "displayPage" to "best"
put (the thumbposition of me) /100 into pPercent
set the rect of image "displayPage" to
scaleImageByPercent(gWidth, gHeight, pPercent)
function scaleImageByPercent pWidth, pHeight, pPercent
