Legend creation - space character issue in 2.6

Anonymous User

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;

        }
