Legend creation - space character issue in 2.6

Anonymous User — Tue, 17 Nov 2020 07:15:33 GMT

Hi Guys,

I have code dynamically generate the legend.

Working well with 2.5

In 2.6, the spacing seem to be issue.

What is the changes in 2.6 related to layout tool legend objects?

I am using usual approach like create legend and changing font from the CIMLegend from definition.

Legend resultLegend = LayoutElementFactory.Instance.CreateLegend(activeLayoutView.Layout, leg_env, activedMapFrame);

Below is the screenshot, left is 2.6, right is 2.5

Left legend is 2.6, Right Legend is 2.5

Any Idea? @UmaHarano @Wolf

Hi Guys,

I managed to solve this issue.

The problem is at generating the text symbol.

Have to add the following properties to make spacing work properly in 2.6 and 2.7.

destinationTextSymbol.LetterWidth = 100;
destinationTextSymbol.WordSpacing = 100;
destinationTextSymbol.Kerning = true;
destinationTextSymbol.Ligatures = true;
destinationTextSymbol.FontType = FontType.TTOpenType;
destinationTextSymbol.ExtrapolateBaselines = true;
destinationTextSymbol.HaloSize = 1;

Best Regards,

Than

Hi,

I am also trying to customize my legend. Your solution is to use destinationTextSymbol in controlling the text properties in the legend. Can you please elaborate a bit on this solution?

The following is my code for creating a legend. But after that, I am confused on HOW and WHERE to insert CIMTextSymbol reference such as your destinationTextSymbol. Can you please help me with that? Thanks.

Coordinate2D llLegend = new Coordinate2D(10, 10); Coordinate2D urLegend = new Coordinate2D(100, 50); Envelope leg_env = EnvelopeBuilder.CreateEnvelope(llLegend, urLegend); LayoutElementFactory.Instance.CreateLegend(layout, leg_env, mfElm);

Hi @GyanendraGurung ,

Here is the code snippet, the destinationTextSymbol is the variable actually,

Sorry, I didn't post full set of code earlier.

Let me know when you got issue,

//Separate method public void FormatDefaultArialTextSymbol(CIMTextSymbol sourceTextSymbol, CIMTextSymbol destinationTextSymbol, string FontStyleName, double fontSize, double height) { destinationTextSymbol.CopyFrom(sourceTextSymbol); destinationTextSymbol.FontStyleName = FontStyleName; destinationTextSymbol.FontFamilyName = "Arial"; destinationTextSymbol.Height = height; destinationTextSymbol.SetSize(fontSize); destinationTextSymbol.ExtrapolateBaselines = false; destinationTextSymbol.VerticalAlignment = VerticalAlignment.Center; destinationTextSymbol.BillboardMode3D = BillboardMode.None; destinationTextSymbol.Symbol3DProperties = new CIM3DSymbolProperties() { DominantSizeAxis3D = DominantSizeAxis.Z, ScaleY = 0, ScaleZ = 0, RotationOrder3D = RotationOrder.XYZ }; //from 2.6 - word spacing and letter width are required to set and ,need to be 100 destinationTextSymbol.LetterWidth = 100; destinationTextSymbol.WordSpacing = 100; destinationTextSymbol.Kerning = true; destinationTextSymbol.Ligatures = true; destinationTextSymbol.FontType = FontType.TTOpenType; destinationTextSymbol.ExtrapolateBaselines = true; destinationTextSymbol.HaloSize = 1; } /// actual code //Get layout and map frame first LayoutView activeLayoutView = LayoutView.Active; MapFrame activedMapFrame = activeLayoutView.ActiveMapFrame; ProgressorSource ps = new ProgressorSource("Adding Legend..."); QueuedTask.Run(() => { Console.WriteLine("Create legend area"); //Search for a style project item by name StyleProjectItem arcgis_2dStyle = Project.Current.GetItems<StyleProjectItem>().First(si => si.Name == "ArcGIS 2D"); Envelope mapFrameExtent = (activedMapFrame.GetDefinition() as CIMMapFrame).Frame.Extent; double xmin = mapFrameExtent.XMax - (mapFrameExtent.Width / 4); double bufferX = mapFrameExtent.Width * 0.01; double bufferY = mapFrameExtent.Height * 0.01;//1% double xmax = mapFrameExtent.XMax - bufferX; double ymax = mapFrameExtent.YMax - bufferY; double ymin = mapFrameExtent.YMin + bufferY; Envelope leg_env = EnvelopeBuilder.CreateEnvelope(xmin, ymin, xmax, ymax); Legend resultLegend = LayoutElementFactory.Instance.CreateLegend(activeLayoutView.Layout, leg_env, activedMapFrame); CIMLegend legendDef = resultLegend.GetDefinition() as CIMLegend; legendDef.Title = "Legend"; legendDef.ShowTitle = true; SymbolStyleItem paragraph = arcgis_2dStyle.SearchSymbols(StyleItemType.TextSymbol, "Paragraph").FirstOrDefault(); CIMTextSymbol aParaSymbol = paragraph.Symbol as CIMTextSymbol; FormatDefaultArialTextSymbol(aParaSymbol, (legendDef.TitleSymbol.Symbol as CIMTextSymbol), "Bold",12,8); legendDef.AutoAdd = true; legendDef.AutoFonts = true; legendDef.AutoVisibility = true; legendDef.FittingStrategy = LegendFittingStrategy.AdjustColumnsAndSize; ps.Message = "Adding Legend - Formatting Text"; foreach (CIMLegendItem legItem in legendDef.Items) { FormatDefaultArialTextSymbol(aParaSymbol, (legItem.HeadingSymbol.Symbol as CIMTextSymbol), "Regular",8, 8); FormatDefaultArialTextSymbol(aParaSymbol, (legItem.LabelSymbol.Symbol as CIMTextSymbol), "Regular",8, 8); FormatDefaultArialTextSymbol(aParaSymbol, (legItem.DescriptionSymbol.Symbol as CIMTextSymbol), "Regular",8, 8); FormatDefaultArialTextSymbol(aParaSymbol, (legItem.LayerNameSymbol.Symbol as CIMTextSymbol), "Bold", 9, 8); FormatDefaultArialTextSymbol(aParaSymbol, (legItem.GroupLayerNameSymbol.Symbol as CIMTextSymbol), "Bold", 9, 8); legItem.AutoVisibility = true; } resultLegend.SetName("Legend"); resultLegend.SetDefinition(legendDef); }, ps.Progressor);
