Zoom webpage not working in 1.6.1

Asked by Marco Antonio Moraes

Hi all,

I have the following problem: When I insert a webpage with zoom applied, a white screen with the site name appears in the display. The same happens with offset applied. When I use offset to 0 and zoom in 100%, the webpage appears normally.
I tested in IE9 and IE11 on Windows 7 x86 SP1.
The client and server are 1.6.1.
In version 1.5 it did not happen.

Sorry for my english.

Best regards,

Marco

Can you let us know which webpage you are trying? Can you also try with http://xibo.org.uk?

Hi Dan,

I have tested in IE10 too and the result is same. A blank screen.
I have tested the site http://xibo.org.uk, but the result was a blank screen.
Below the image on this link in my server:
http://signage.midianix.com.br/images/errors/blank_screen.jpg
The sites that I need to show is http://www.metro.sp.gov.br and http://www.cetsp.com.br
In registry, the patch to IE10 was applied.
Remembering that when I applied the zoom above or under 100% this happen in 1.6.1 version.
Sorry for my english.

Best regards

Marco

Is there any way I can debug what happens on the client?

Hi Marco,

I've been unable to recreate your issue on our dev environment, which unfortunately means that we need to do a little more digging on your end.

The client will inject an IFRAME into the standard .NET webbrowser which will look something like this:

<html>
 <body style='margin:0; border:0;'>
  <iframe style='border:0;margin-left:-10px; margin-top:-10px;zoom: 1.5;' scrolling="no" width="692.666666666667px" height="394px" src="http://www.cetsp.com.br/">
 </body>
</html>

Depending on the size of your client window and region.

Can you enable right click in the settings and then right click on the empty screen you get, a select view source? Try and get the edge so that you see the source for the container rather then the website.

Does your media item behave correctly when looking at it in the layout designer?

Thanks,
Dan

Hi Dan,

Thanks for your reply.

When I get the source code of the page with problems inside the region, the source code is:

<HTML>www.cetsp.com.br</HTML>

Just that.

The title in notepad appers:

about_www.cetsp.com.br[1]

In layout design on the server, the webpage appears normally, just without the zoom, but the zoom is applied on the timeline.

Maybe some misconfiguration on the server?

My server is Ubuntu 14.04 LTS x64 with apache2.

In client, the Flash version is 14. I dont know if make conflict.

Hi Dan,

I have tested the zoom webpage on my server in version 1.4.2 and the problem persists.

I believe the problem is on the server with the configuration.

Apache2 is 2.2.22 version.

Hi Marco,

The CMS does (did) have some problems with web page zoom, but those are unrelated to the client unfortunately. You can see the link to that issue here (https://bugs.launchpad.net/bugs/1330105).

I am not sure what to suggest with your issue on the client - the client is in charge of making its own HTML/IFRAME when there is scaling / offset to be done.

Can you try leaving the scaling at 100 and just selecting a very small offset, say 1 and 1?

Hi Dan,

When I applied the small offset, the blank screen appears too.

I have clicked right click and select properties in webpage, the URL field is set "about:www.cetsp.com.br". Any site result is same: Google, xibo.org.uk.

And analising the source code by right click, the iframe tag, the zoom option is set zoom: 1,5" not zoom: 1.5.

Sorry for my English.

Regards

Marco

The source code:

<html>
<body style='margin:0; border:0;'>
<iframe style='border:0;margin-left:-1px; margin-top:-1px;zoom: 1,5;' scrolling="no" width="534,333333333333px" height="401px" src="www.google.com.br">
</body>
</html>

<HTML>www.google.com.br</HTML>

Marco... thanks for this diagnosis, very useful. It is almost certainly a regional settings bug (I will create a bug for it).

Can you double check by changing the regional settings separator to a "." instead of a ",".

Dan... I am brazilian, so my client and browser is set to portuguese (brazilian) - pt-BR.

Hi Dan,

I have news: I changing the regional settings separator to ".", the iframe tag works fine!

The zoom is applied correcty.

Another setup I did was add the prefix http:// inserting webpage on the CMS. I did only insert site without prefix http://.

Thanks very very very much Dan.

I'm pleased you have it working!! :-)

I'll follow up on that bug when I can, so that you don't have to use the workaround for future displays.

Thanks,
Dan
