android - WebView autoscales local images -

-

my question similar this one, different enough going post new one.

i writing image viewer downloads png remote server, saves storage, , opens in webview multi-touch zoom free. these images going documents, user want able zoom in far. sending down images of sufficient resolution enable this, webview seems "helping" me scaling image screen size start out with. means image low resolution zoomed in on.

i have searched around this, , have found other people encountering similar problem, possible solution found cut image tiles , reassemble them using html before loading in view. seems kludge, , asking stackoverflow hivemind if has either way turn off scaling, or alternative method need.

the code initializes webview:

viewer = (webview)findviewbyid(r.id.activity_imageviewer_webview); viewer.setbackgroundcolor(0); websettings settings = viewer.getsettings(); settings.setjavascriptenabled(false); settings.setbuiltinzoomcontrols(true); settings.setusewideviewport(true); settings.setloadwithoverviewmode(true);

the code loads image webview:

viewer.loadurl(uri.fromfile(imagefile).tostring());

changing viewport properties might help, take @

<meta name="viewport" ...>

meta tag in html header

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
