How to zoom on in a image on click of it
hi Team,
We have a requirement where in we need to allow user to upload a image and or select a image from a dropdown. and on select, display the image on screen and on click of the image, it should be popped out or get maximized and there should be an option to make it again as it was. like zoom in zoom out option. i tried pyMenu_Zoom navigation rule on the click of image and menu rule gets fired, but on click of the options , zoom in zoom out doesnt happen. Also, the scripts which are configured to run on the zoom in ,zoom out option is not visible in the pega. I also explored the option of pzdisplayImage control but i am attaching the image via attachment control and with it, the file gets stored in pyAttachmentPage of Data-WorkAttach-File class. I took the pzinskey of file from this page and file type and passed it to the pzdisplay control but the image doesnt get displayed at all. - can you kindly suggest how we can achieve this.

One approach to achieve the image zoom in/out functionality could be to use a JavaScript library like Lightbox or Magnific Popup. These libraries allow you to display images in a modal window with the ability to zoom in/out and navigate through the images.
Here are the steps you can follow:
Add the JavaScript library files to your application. You can either include the files in the HTML rule or use the Static Content rule to upload the files to your Pega application.
Modify the section that displays the image to include an HTML link with the image URL as the href attribute. For example:
<a href="/prweb/PRServlet/custom/fileattachment?fileID=pyAttachmentPage.pyAttachStream&InsKey=<pzinskey>" data-lightbox="image-1" data-title="<Image Title>"> <img src="/prweb/PRServlet/custom/fileattachment?fileID=pyAttachmentPage.pyAttachStream&InsKey=<pzinskey>"> </a> Note: Replace <pzinskey> and <Image Title> with the appropriate values.
Add the necessary JavaScript code to initialize the library and enable zoom in/out and navigation. This code can be added to the HTML rule or a separate JavaScript file. Here is an example code for Lightbox:
$(document).ready(function() {
// Initialize Lightbox

$(document).ready(function() {
// Initialize Lightbox
$('a[data-lightbox]').lightbox({
// Enable zoom in/out
zoomable: true,
// Enable navigation between images
alwaysShowNavOnTouchDevices: true,
wrapAround: true
});
});
Note: Make sure to replace the selector a[data-lightbox] with the appropriate selector for your HTML link.
With these steps, when the user clicks on the image, it will be displayed in a modal window with the ability to zoom in/out and navigate through the images.
