Good afternoon, I've been trying to debug some private byte allocation leaks in my application and finally think I've narrowed it down to the PictureMarkerSymbol.SetSourceAsync() method. My use case consists of updating n number of PictureMarkerSymbol sources/geometries on the map once every ~100ms. Through a combination of Redgate, WinDbg, and ultimately DebugDiag I pinpointed the culprit (I think) to RuntimeCoreNet calling into msvcr120::malloc. I'm setting the source of my PictureMarkerSymbols like this: private async void periodicUpdate() {             BitmapFrame frame = BitmapFrame.Create(this.someBitmapSource);             PngBitmapEncoder encoder = new PngBitmapEncoder();             encoder.Frames.Add(frame);             using (Stream stream = new MemoryStream())             {                 encoder.Save(stream);                 stream.Seek(0, SeekOrigin.Begin);                 await this.pictureSymbol.SetSourceAsync(stream);             } } Has anyone else encountered this issue? Am I setting the source incorrectly or otherwise missing something else? The leak seems to be pretty linear in growth and will generate an OutOfMemoryException fairly reliably. ... View more

Hello, Previously using the ArcGIS WPF Runtime I could create and initialize a map off-screen and render it to a bitmap using RenderTargetBitmap. I'm wondering if there is a preferred method to doing this as I'm currently unable to get a MapView to render unless it's in view, which isn't an option for this use case. // Sample code Grid grid = new Grid(){Width=width, Height=height}; Map map = new Map(){Width=width, Height=height}; map.Layers.Add(someLayer); grid.Children.Add(map); grid.Measure(new Size(width, height)); grid.Arrange(new Rect(new Size(width, height))); grid.UpdateLayout(); map.Extent = someExtent; RenderTargetBitmap rtb = new RenderTargetBitmap(width, height, dpi, dpi, PixelFormats.Default); rtb.Render(grid); // Do something with the image here // End Sample The sample above is a simplified version of what I'm doing, but the fundamentals are the same. In the .NET 10.2.7 runtime this results in blank images. How can I recreate this behavior in the .NET Runtime? It appears that the map is never initialized unless I bring it into view.

Hello, I'm upgrading an application from the 10.1.1 WPF Runtime to the 10.2.6 .NET Runtime and am having some issues with TextSymbol display. I'm using TextSymbols on a GraphicsLayer to label dynamic graphics and am finding that the text looks jagged/not anti-aliased. If I switch the AngleAlignment to 'Map' it removes the jaggedness but the text becomes very blurry. Is there a method to enable anti-aliasing or turn on clear type like I could have done in the WPF Runtime? Below are a couple of examples of what I'm seeing: Normal Text: Italicized Text: The first example generally only occurs when the geometry is moving and sometimes when the movement has stopped it will retain that very fragmented/unreadable look. The second italicized text is all of the time. If anyone has any insight/tips on how to remedy this I'd be much obliged. Thanks, Aaron ... View more

Hi, I have a custom class that implements the Esri.ArcGISRuntime.Layers.TiledLayer class to display some operational raster data on a Runtime for .NET 10.2.6 map. The layer behaves as expected when panning/zooming, however if some portion of the operational data changes I need to be able to "refresh" or redraw the visible data/tile(s). My first thought was to use the exposed TilerLayer::Invalidate()​, however this simply clears the entire internal tile cache. What would be ideal is if I had a way to either: a) Access the internal CoreLayer::SetTile() method and manually reset the tile that has changed with the new data or b) "Poke" the map object and get it to re-request the visible tiles using the TiledLayer::GetTileDataAsync()​ The problem with the invalidation call is that it causes a flickering rather than a smooth animation like normal pan/zoom operations. Is there a way to do what I'm looking for? If not, was this intentionally left out of the public API? The latter question is pointed more towards my inclination to access the CoreLayer with reflection. Thanks, Aaron ... View more

Hi, In ArcObjects it is possible to specify what type of output features are desired on an intersect operation, is the same operation possible in the WPF Runtime? I've experimented with the Intersect task but the return geometry type is always equal to the input type. Specifically, I'd like to be able to calculate a the specific location along a geometry where an intersection occurs. For example, I'd like to know where on a polyline it is intersected by another polyline or polygon as a point location. Is this possible through other means if I can't specify an output geometry type on an intersect task? Thanks, Aaron ... View more
