GradientAngle: Double;
The GradientAngle property determines legend background gradient angle.
This property is relevant if:
The IMapBackground.Type property uses the MapBackgroundType.Gradient fill type.
Gradient fill color is set using the IMapBackground.GradientColor property.
Executing the example requires that the repository contains a form containing the components:
ReportBox with the ReportBox1 identifier.
UiReport with the UiReport1 identifier that is a data source for ReportBox1.
It is also required to have a regular report containing a map with enabled legend that is a data source for UiReport1.
Add links to the Drawing, Map, Report, Tab system assemblies.
Sub UserProc;
Var
regrep: IPrxReport;
sheet: IPrxSheet;
table: IPrxTable;
objects: ITabObjects;
map: IMap;
legend: IMapLegend;
background: IMapBackground;
Begin
// Get regular report
regrep := UiReport1.Report;
// Get map from regular report
sheet := regrep.Activesheet;
table := sheet As IPrxTable;
objects := table.TabSheet.Objects;
map := objects.Item(0).Extension As IMap;
// Get map legend
legend := map.View.Legend;
// Get legend background on map
background := legend.Background;
// Set legend gradient fill type
background.Type := MapBackgroundType.Gradient;
// Set gradient color
background.GradientColor := New GxColor.CreateRGB(120, 0, 120);
// Set gradient angle
background.GradientAngle := 45;
// Refresh map
map.Refresh;
End Sub UserProc;
After executing the example legend background fill becomes gradient, gradient angle becomes equal to 45°.
