问题 I found that WriteableBitmap.Render() is not supported in WinRT. Is there any other API for drawing bitmap images in Metro? I need to render some xaml-primitives (Rectangles, Circles, Paths, etc.) to png-image. 回答1: It is indeed not supported yet. Your best bets are to either use WriteableBitmapEx or Direct2D. 来源： https://stackoverflow.com/questions/11840835/rendering-an-image-at-runtime-in-winrt

问题 I succeed installing Box2D into my project. But how can I render a body? Assume I'm using something that supports drawing polygons. I just want to find out the current positions of the vertices of the body-polygon, to draw it with the engine.

问题 I try to make newsletter compatible with Outlook 2007, but Outlook rendering engine isn't very logical. Following code is not making borders as width of 1 pixel like in Firefox and other rendering engines, but it adds some extra space between some of these td-elements. Is there a workaround for this issue ? <table> <tr> <td width="0" style="border-left: 1px solid #cdcdcd; border-bottom: 0px none; border-top: 0px none; margin: 0;" ></td> <td width="0" style="border-left: 1px solid #c1c1c1;

问题 I'm building a Java application that is some sort of Android applications (APK files) analyzer. One of the main features that the app will offer is a "preview" of an Android layout, hence I need an API that receives an Android layout XML and a few configuration arguments such as screen resolution and theme, and returns the rendered layout as it would appear on a device running the application (graphical consistency with the real Android platform is important) along with position data of the

问题 I need to store the content of a Window into an image, save it and close the window. If I close the window on the Loaded event the image contains the Window with some items are drawn ok, some others are only half drawn or distorted while others are not on the image. If I put a timer and close the window after a certain amount of time (something between 250ms and 1sec depending on the complexity of the window) the images are all ok. Looks like the window needs some time to completely render

问题 We are trying to load a pdf file in web browser using pdfobject javascript api. Currently the size of the pdf's that we are trying to display is close to 10MBs. This creates a long delay in displaying a PDF on web page; while the complete PDF gets downloaded. We need to remove this lag by achieving either of the alternatives: Show a progress bar until the PDF is actually displayed. We couldn't find an event which is triggered and can be used to find out if pdf is visible now. This lacking

问题 I am having an issue only with Chrome (so far that I can tell). On this website: www.elliott-web.com the homepage displays a random image on load. After several reloads I get no image showing up, but when checking the http requests I see the image is there. Similarly, on the portfolio page if you click forward and backward through the images, eventually an image will no longer show up. Again, looks like the image is there but it's not being displayed. Thought maybe it has to do w/ Chrome's

问题 I was reading a post by Brad Wilson (http://bradwilson.typepad.com/blog/2008/08/partial-renderi.html) on the new ViewEngine changes to MVC Preview 5 and thought that it would be great to be able to render a view to string for use in tests. I get the impression from the article that it may be possible to achieve this but cannot figure out how. I believe this would enable us to do away with some of our WatIn tests (which are slow and unreliable) as it would allow us to check that the View has
