问题 UPDATE: We replaced the Image generation with an alternative that solves the issue (PDF to image) but I am going to leave this question open as I would like to understand if this is possible. On our website at http://www.cloudformatter.com, we were attempting to implement some code for processing our generated XPS files to image.

If anyone is interested, find it below: VisualBrush VisualBrush1 = new VisualBrush(); VisualBrush1.TileMode =

问题 I need to take snapshots of Control in time and store them in one FixedDocument. Problem is that VisualBrush is somehow "lazy" and do not evaluate itself by adding it to document. When I finaly create the document, all pages contains the same (last) state of Control. While VisualBrush cannot be Freezed, is there any other chance to do it? I would like to have more snapshots on one page so generate document page by page isn't solution for me. Aswel as converting VisualBrush to Bitmap (I want

问题 i have a problem with the WPF VisualBrush . Here you find two images from my application. The bigger on is a image which shows a control with text.

Visual brush using control which isn't rendered?

为君一笑 提交于 2019-12-04 05:01:55
问题 I'm playing around with an idea at the moment and I've hit a brick wall. I'm using a console app to create a visual control (DevExpress chartcontrol to be precise) in memory, I'm then trying to save that control to an image using a VisualBrush but it won't work because (I assume) the control isn't drawn to the screen. I've put my code in below so you know where I am at the moment. Does anyone know how I could possibly save this control to an image (ideally jpg, but anything will do...) using

Get System.Drawing.Bitmap of a WPF Area using VisualBrush

强颜欢笑 提交于 2019-12-02 02:37:58
问题 The point is, that I need to convert to a System.Drawing.Bitmap (.Net Framework 2.0) to get a single frame of an WPF Grid with its content. I read about VisualBrush and DrawingBrush but I cannot imagine how it should work. I can convert any WPF BitmapSource into my System.Drawing.Bitmap successfully. But how to receive the BitmapSource from my Grid? Thanks 回答1: To convert a Visual to BitmapSource you can use RenderTargetBitmap, VisualBrush and DrawingVisual: public BitmapSource
