In an addin i'm creating there's a button that will add a raster layer to my map based on a selected value in a listbox. The code is simple and works fine: the new layer appears in the TOC and the image appears on the map, but curiously all visibility checkboxes on layers in the TOC become greyed out for a while. After a minute or so, they become enabled again. I'm guessing something is going on in a background thread that is setting the visibility checkboxes to disabled while it is doing whatever it is doing. The question is what is it doing?  The images are around 10mb each and georeferenced. private async void cmd_ButtonAdd_Click(Object sender) { Layer pImgLay; string url = selectedObliqueVal; url = m_imgPath + m_Isle + m_imgFolder + "A" + url.Substring(1, 1) + @"\" + url + ".jpg"; if (!System.IO.File.Exists(url)) { MessageBox.Show("File does not exist:\r\n" + url); return; } pImgLay = await QueuedTask.Run(() => { return LayerFactory.Instance.CreateLayer(new Uri(url), MapView.Active.Map); }); _addedImages.Add(url); //MessageBox.Show("Add"); }   ...

I created some ArcObjects code that creates a geoprocessing tool that creates a featureclass from some input files. The code creates a GP tool that works as it should, except for one problem: the GP parameter for the input files accepts all files when it is supposed to only accept files with the extension .jxl or .xls. There is no documentation on how to do this, but below is the code snippet of what I wrote to create the input file parameter.  I've also converted the tool to a Python tool (which has much better documentation) and it does filter input files to just the allowed ones. I assume the underlying objects are the same for the .Net SDK as for ArcPy, so there should be a way to get the .net authored tool to work as well. I also looked for clues in the Pro SDK, but came up with nothing since Pro doesn't even support creating GP tools with .net.

I want to put some custom maptools into a dockpanel addin. I have found how to do this and run it from an RelayCommand and it works using the little bit of code below, but I was wondering about the parameter that you can pass to the tool. Can this be anything? If so, how do I get at it from within my maptool?   IPlugInWrapper pWrapper = FrameworkApplication.GetPlugInWrapper("PukaWai_GetFeatTool"); if (pWrapper is ICommand toolCmd) { // toolCmd.Execute(null); toolCmd.Execute("parameter"); }   ...

I wrote a bit of code to show me the extent (footprint) of a raster with a Polyline. It should be fairly simple by getting the map coordinates of four corner pixels of the raster. Yes, I'm aware that those should give me the coordinates of the center of those pixels, but that's fine. The code works fine for Rasters with orthogonal georeferencing, but has problems if the georeferencing rotates and stretches the image. See screenshot below for the results I'm getting await QueuedTask.Run(() => { pOutLay = (FeatureLayer)LayerFactory.Instance.CreateLayer(new Uri(url), MapView.Active.Map); pSpatRef = SpatialReferenceBuilder.CreateSpatialReference(32655); //UTM55N EditOperation createFeatEditOp = new EditOperation(); createFeatEditOp.Name = "CreateImageEdges"; createFeatEditOp.SelectModifiedFeatures = false; createFeatEditOp.SelectNewFeatures = false; foreach (Item itm in items) { lstPnt = new List<MapPoint>(); string path = itm.Path.Substring(0, itm.Path.LastIndexOf(@"\")); string strFile = itm.Path.Substring(itm.Path.LastIndexOf(@"\") + 1); FileSystemConnectionPath connectionPath = new FileSystemConnectionPath(new System.Uri(path), FileSystemDatastoreType.Raster); FileSystemDatastore dataStore = new FileSystemDatastore(connectionPath); RasterDataset fileRasterDataset = dataStore.OpenDataset<RasterDataset>(strFile); Raster pRas = fileRasterDataset.CreateDefaultRaster(); pTup = pRas.PixelToMap(0, 0); lstPnt.Add(MapPointBuilder.CreateMapPoint(pTup.Item1, pTup.Item2)); pTup = pRas.PixelToMap(0, pRas.GetWidth()); lstPnt.Add(MapPointBuilder.CreateMapPoint(pTup.Item1, pTup.Item2)); pTup = pRas.PixelToMap(pRas.GetHeight(), pRas.GetWidth()); lstPnt.Add(MapPointBuilder.CreateMapPoint(pTup.Item1, pTup.Item2)); pTup = pRas.PixelToMap(pRas.GetHeight(), 0); lstPnt.Add(MapPointBuilder.CreateMapPoint(pTup.Item1, pTup.Item2)); pTup = pRas.PixelToMap(0, 0); lstPnt.Add(MapPointBuilder.CreateMapPoint(pTup.Item1, pTup.Item2)); pPline = PolylineBuilder.CreatePolyline(lstPnt, pSpatRef); dctAtts = new Dictionary<string, object>(); dctAtts.Add("SHAPE", pPline); dctAtts.Add("Image", strFile); dctAtts.Add("Width", pRas.GetWidth()); dctAtts.Add("Height", pRas.GetHeight()); createFeatEditOp.Create(pOutLay, dctAtts); } createFeatEditOp.Execute(); }); } catch (Exception ex) { MessageBox.Show(ex.Message); } } The size of this image is 8272x6200 and you can see in the table that I'm not getting the correct height from the Raster object either. Any idea what's going on here? ... View more

I am trying to use some custom datum transformations in Pro. These were created to work in conjunction with a standard transformation as a composite transformation. I have noticed that the standard transformations are bi-directional, i.e. the same transformation is used no matter which is the "from" datum and which is the "to" datum.  The custom transformations are also bi-directional, but they only show up for one direction in the transformations list box in Map properties. I've found some workarounds but neither is ideal: If my custom transformation doesn't show up, I can change my map spatial reference to be the same as the layer that needs the transformation, then select the transformation that uses the custom transformation, and then switch the map spatial reference back again. (The selected transformation remains and works as it should) The second workaround involved writing a .net AddIn to set the transformation which works great but is limited to the custom transformations it is written for. The third workaround is to develop a second set of custom transformations that work in the reverse direction. Is there some way to get Pro to consider custom transformations as bi-directional when it decides what transformations to show in the dropdown list?   ... View more
