I can't understand why this doesn't work, or what I need to get it to work. To repro, create a simple WPF application and replace the main window's constructor thusly: public MainWindow() { InitializeComponent(); // simple visual definition var grid = new Grid { Width = 300, Height = 300 }; var ...
I'm wanting to export a 3D scene from a Viewport3D to a bitmap. The obvious way to do this would be to use RenderTargetBitmap -- however when I this the quality of the exported bitmap is significantly lower than the on-screen image. Looking around on the internet, it seems that RenderTargetBitmap doesn't take advantage of hardware rende...
Im trying to create some chart images without ever displaying those charts on the screen. I'v been at this for quite a while and tried a lot of different things but nothing seems to work. The code works perfectly if I display the chart in a window first, but if I don't display it in a window, the bitmap is just white with a black border ...
I've found a new twist on the "Visual to RenderTargetBitmap" question! I'm rendering previews of WPF stuff for a designer. That means I need to take a WPF visual and render it to a bitmap without that visual ever being displayed. Got a nice little method to do it like to see it here it goes private static BitmapSource CreateBitmapSou...
Hi I use Viewport3d and display my 3D Elements with inherited UIElement3D classes... Now I want to make different images of my viewport (different views). That means I have to make a new viewport3d at runtime and apply my specific view for the image on it.. see the following code: ' Start creating Image Dim bitmap As New RenderTargetB...

Does anyone have an idea why? Here's the code. public static byte[] Draw(int width, int height) { MemoryStream memoryStream ...
Hi all, The WPF application I have build has a Viewport3D containg all kinds of UIElement3D objects. Now I would like to save a high resolution snapshot of a certain view to a file. I have tried RenderTargetBitmap in the past, but I do not like this approach because of the following downsides: Memory leakage (at least with .NET 3.5 S...
Hi, I've found a perfect storm of conditions that create a situation where my panel is no longer updating properly. Here is the concept: I have a grid with a viewbox displaying a canvas with lines in radiating patterns. When I attempt to render the entire grid to bitmap, the bitmap looks fine. However, at this point forward, if I ch...
Hello - I wrote a very simple WPF application to test the ability to render a control that has an associated pixel shader to a RenderTargetBitmap. I then write the bitmap to file (jpeg). The control is rendered onto the bitmap, however the pixel shader effect is not applied to the control. The code and the XAML is below: namespace...
