Firstly, apologies if it appears I'm spamming the boards; that's not my intention, I'm just struggling to find a workable solution to the problem I've got.
I need to encrypt a url using Base 64 / SHA1 encryption. I'm sure that's not available natively within Qlikview so I'm wondering where I can write this functionality where it would be accessible to the dynamic image source of a chart.
you could create an extension object where you can use the JavaScript function b64_sha1() to encrypt the URL and render the image. Place the object under the chart.
