Hello, I have questions about display images in Ignition Perspective. I am setting the source for an image component to: "https://server_name/main/screens/NewImage.png". NewImage is constantly updated on remote server. But in Perspective session image component continues to show original PNG and update new only when I refresh webpage. Is it possible to update the image displayed in perspective without refreshing the page?
Add a variable to url with a changing value like milliseconds. https://server_name/main/screens/NewImage.png?v=1984355000
Yep I do the same thing on PDFs with an expression
concat( 'http://testsite/003430.pdf?t=', now(0) )
I add a variable to url with changing value, but this doesn't solve me issue. Still the image does not refresh on the perspective screen. But I noticed that when i right click on the image and select open in new tab, the most recent image opens.
I don't really like this method, but you could try setting the source to
'' then back to the correct source string and see if that forces a reload. However, I think the url with a time parameter should work. How did you set it up?
