The Structure of Drawings com.sun.star.drawing.CircleKind.SECTION circle slice com.sun.star.drawing.CircleKind.ARC angle (not including circle line) The following example creates a circular slice with a 70 degree angle (produced from difference between start angle of 20 degrees and end angle of 90 degrees) Dim Doc As Object Dim Page As Object Dim EllipseShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) EllipseShape = Doc.createInstance("com.sun.star.drawing.EllipseShape") EllipseShape.Size = Size EllipseShape.Position = Point EllipseShape.CircleStartAngle = 2000 EllipseShape.CircleEndAngle = 9000 EllipseShape.CircleKind = com.sun.star.drawing.CircleKind.SECTION Page.add(EllipseShape) Lines OpenOffice.org provides the com.sun.star.drawing.LineShape service for line objects. Line objects support all of the general formatting services with the exception of areas. The following are all of the properties that are associated with the LineShape service: Line properties com.sun.star.drawing.LineProperties Text properties com.sun.star.drawing.Text (with com.sun.star.style.CharacterProperties and com.sun.star.style.ParagraphProperties) Shadow properties com.sun.star.drawing.ShadowProperties The following example creates and formats a line with the help of the named properties. The origin of the line is specified in the Location property, whereas the coordinates listed in the Size property specify the end point of the line. Dim Doc As Object Dim Page As Object Dim LineShape As Object Dim Point As New com.sun.star.awt.Point Dim Size As New com.sun.star.awt.Size Point.x = 1000 Point.y = 1000 Size.Width = 10000 Size.Height = 10000 Doc = ThisComponent Page = Doc.DrawPages(0) LineShape = Doc.createInstance("com.sun.star.drawing.LineShape") LineShape.Size = Size LineShape.Position = Point 122 OpenOffice.org 3.2 BASIC Guide · March 2010
Page.add(LineShape) Polypolygon Shapes The Structure of Drawings OpenOffice.org also supports complex polygonal shapes through the com.sun.star.drawing.PolyPolygonShape service. Strictly speaking, a PolyPolygon is not a simple polygon but a multiple polygon. Several independent lists containing corner points can therefore be specified and combined to form a complete object. As with rectangle shapes, all the formatting properties of drawing objects are also provided for polypolygons: Fill properties com.sun.star.drawing.FillProperties Line properties com.sun.star.drawing.LineProperties Text properties com.sun.star.drawing.Text (with com.sun.star.style.CharacterProperties and com.sun.star.style.ParagraphProperties) Shadow properties com.sun.star.drawing.ShadowProperties The PolyPolygonShape service also has a property that lets you define the coordinates of a polygon: PolyPolygon (Array) – field containing the coordinates of the polygon (double array with points of the com.sun.star.awt.Point type) The following example shows how you can define a triangle with the PolyPolygonShape service. Dim Doc As Object Dim Page As Object Dim PolyPolygonShape As Object Dim PolyPolygon As Variant Dim Coordinates(2) As New com.sun.star.awt.Point Doc = ThisComponent Page = Doc.DrawPages(0) PolyPolygonShape = Doc.createInstance("com.sun.star.drawing.PolyPolygonShape") Page.add(PolyPolygonShape) ' Page.add must take place before the coordinates are set Coordinates(0).x = 1000 Coordinates(1).x = 7500 Coordinates(2).x = 10000 Coordinates(0).y = 1000 Coordinates(1).y = 7500 Coordinates(2).y = 5000 PolyPolygonShape.PolyPolygon = Array(Coordinates()) Since the points of a polygon are defined as absolute values, you do not need to specify the size or the start position of a polygon. Instead, you need to create an array of the points, package this array in a second array (using the Array(Coordinates()) call), and then assign this array to the polygon. Before the corresponding call can be made, the polygon must be inserted into the document. The double array in the definition allows you to create complex shapes by merging several polygons. For example, you can create a rectangle and then insert another rectangle inside it to create a hole in the original rectangle: Dim Doc As Object Dim Page As Object Dim PolyPolygonShape As Object Dim PolyPolygon As Variant Dim Square1(3) As New com.sun.star.awt.Point Dim Square2(3) As New com.sun.star.awt.Point Dim Square3(3) As New com.sun.star.awt.Point Doc = ThisComponent Page = Doc.DrawPages(0) PolyPolygonShape = Doc.createInstance("com.sun.star.drawing.PolyPolygonShape") Chapter 8 · Drawings and Presentations 123
