Sets the ChromiumWebBrowser initialization ZoomLevel

[az235]

Hi,ALL:
I want ChromiumWebBrowser ZoomLevel effect during initialization, how am I supposed to do? Because the resolution is 2160*1440 Surface Pro 3, and page was blank when it is initialized, I want to solve this problem.
PS: in the HTML page loads and displays the ZoomLevel after operation is taking effect.

With WPF or WinForms?

If it's WPF then see #738 it sounds related to your description. #738 mention some known unresolved upstream CEF issue and also some local workaround.

I'm using WPF,#738 is not resolved

#738 is not resolved

No exactly, due to the unresolved upstream CEF project issue.

Can you confirm if your issue is the same/related or something different?

[az235]

My problem with 738 issues basically the same, were due to ChromiumWebBrowser currently only supports 1920*1080, and ZoomLevel attributes and problems arising from the need to be modified after the page is displayed again.

Thank you for your patience to answer

If I need to solve this problem, may I ask, at this stage, do you have any good ways?

[jornh]

Well, yes #738 is a pretty long discussion. If you start at #738 (comment) you see a few upstream CEF references. The best is of course if you are able to work on contributing a fix to CEF. If that's not possible maybe the workaround the original poster over there (@mookrs) used also works for you?

You can see amaitland@a83e480 and amaitland@7c4ef7d then change bjarteskogoy@d08df3d, compile CefSharp.Wpf and get its DLL. This is maybe a temporary solution. Although our own project doesn't use it and remains the HiDPI bug.

Setting the ZoomLevel DependencyProperty causes problems, in the short term I'm inclined to just expose SetZoomLevel on the WPF control so users can call it on FrameLoadStart until a clean solution can be derived.

Fixed by this: #842

As of 39.0.0 there is a usable workaround. See #738 (comment)

As there are a number of other issues that represent this topic I'm going to close this one.
