The application I'm working on needs to be export layouts to PDF and other formats. My team first did this using the ArcGIS Pro .NET SDK Layout class's export methods. In order to eliminate references to Desktop namespaces, we're now exporting via ArcPy by importing a layout from pagx and calling ExportToPDF and other format-specific methods. All of our elements are in place, but all of the colors are slightly different from the .NET SDK to ArcPy. Is this a known issue? Are there certain defaults that are different between platforms? ...

When instantiating an ArcGIS Pro dockpane, the base class's virtual InitializeAsync() method makes it possible to use asynchronous methods in the pane's instantiation. There are several places in our code where we override this method in our dockpane view models (and call asynchronous methods), and they works just as expected. I'm dealing with a case where I need to do the same thing with a Arc Pro button, but the Button class and its parent classes don't include an InitializeAsync() method. Is there a roughly equivalent solution? ... View more

I'm trying to programatically create a few types of charts within a Layout - point charts, line charts, and bar charts. Line charts and bar charts are both going to be sets of polylines, and given that Polyline objects can be combined to make one big Polyline, these chart types require only one call to LayoutElementFactory.Instance.CreateLinegraphicElement (we can just pass the combined Polyline). I'm not seeing a similar method that takes a Multipoint. So, in the case of a point chart, we're having to call CreatePointGraphicElement for every single point on the chart, passing each Coordinate2D at a time. Are there plans to add a method to LayoutElementFactory that takes a MultiPoint, a list of MapPoints, or a list of Coord2D? Either an overload of CreatePointGraphicElement or a new method called something like CreateMultiPointGraphicElement? If not, is there a workaround that would allow for the creation of a multiple point GraphicElement with only one call to a LayoutElementFactory creation method? Element creation incurs a lot of overhead, and thus far we've been able to make big improvements in performance by condensing those calls. ... View more

I am manipulating a Layout brought into memory using the ConvertLayoutFileToLayout() method. Once I have this Layout modified as I wish, is there a way to get it back into PAGX format? This is all happening in a script running outside of the Arc Pro GUI, but I want a user to be able to bring the modified Layout back into Arc Pro for viewing and further, manual modification. ...

I have a Layout that contains various graphic elements. I want to get the symbol from a specific graphic element in order to apply it to the renderer of a layer within a map in a mapFrame in the Layout. In the .NET SDK, this is fairly simple - you can reference graphicElement.Graphic.Symbol (which is a CIMSymbolReference), and then assign that Symbol to the Symbol property of a CIMUniqueValueClass. The corresponding logic in ArcPy would be to assign something to the symbol property of an Item, which is part of an ItemGroup, which exists within the groups property of your UniqueValueRenderer. However, I'm not seeing any way to get the specific symbol that a specific graphic element is using. The documentation for symbol says, "The easiest way to update a symbol is to use the applySymbolFromGallery method." But what if we can't do that? The symbol I'm interested in isn't necessarily a stock, named symbol, but a symbol the user may have customized on their layout before this whole rendering process takes place. Is there some way to access what I need through the CIM (within Python)? If so, how would I take that CIM object and convert it into a Symbol object that can be assigned to an Item? ... View more
