Hello All,

There is a RadImageEditor in my page and after applying Alpha filter the image is vanishing somewhere and the html tag is only displayed with the exact dimension of the image. This issue is occuring in IE9 only (don't know about previous IE Versions) and working fine in MF,Chrome. Is this a browser comatibility issue?

Thanks,
Ben.

Hello Ben,

There is a known issue in RadImageEditor with IE9 Compatibility modes. It applies in the following case:

  • IE9 with "Browser Mode" different than IE9 or Document Mode different than IE9

  • Windows 7 adjusted for best appearance

RadImageEditor uses the MS Filters for some of its operations performed on the client for the older Internet Explorer browsers (IE6, IE7 and IE8). These are the filters used:

  • Matrix Filter
  • Alpha Filter
  • FlipH Filter
  • FlipV Filter

If this filters are applied to an image ( <img/> element) and the page is viewed in IE9 with "Browser Mode" different than IE9 or Document Mode different than IE9, under Windows 7 adjusted for best appearance, the actual image is not shown - the <img/> element is shown and has the exact dimensions of the image but the image is invisible.

No known fix is available for the moment, and our recommendation is setting a <meta/> tag in the <head/> section of the document, that will explicitly tell the browser to use Browser Mode: IE9 and Document Mode: IE9.

ASPX:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

Thanks,
Princy.
