How can I customise jquery loupe to have a circular lens?
To have a circular zoom area instead of rectangular one? There is an option to set a css class for the loupe.
Please note that this is a question about the library linked above. I have already googled for other libraries. I want to keep the js as small as possible.
From the developer of loupe.js:
you may want to look at chris iufer's loupe, which is only a bit bigger than mine and includes a few samples that use css3 to achieve a round loupe:
whereas mine uses an absolutely positioned image within a div, his uses background-image on the div and background-position to move the image, so css3 border-radius works.
