Libraries.Data.Formats.ScalableVectorGraphics.Polyline Documentation

The Polyline class is an implementation of the polyline shape in the SVG standard. The polyline is used to make open shapes using a set of points. Note that when using a set of points the points are pairs of absolute coordinates. Like other ScalableVectorGraphicsObjects the polyline class inherits global attributes but it also has its own attributes.

Example Code

Libraries.Data.Formats.ScalableVectorGraphics.all

Polyline polyline
polyline:AddPoint(100,100)
polyline:AddPoint(50,25)
polyline:AddPoint(50,75)
polyline:AddPoint(100,0)
polyline:SetFill("none")
polyline:SetStroke("black")

Inherits from: Libraries.Language.Object, Libraries.Data.Formats.ScalableVectorGraphics.ScalableVectorGraphicsObject

Actions Documentation

AddPoint(integer x, integer y)

This action adds a point with a given x and y to the list of points that construct the polyline. Note that these points must be absolute coordinates.

Parameters

  • integer x: The x position of the point.
  • integer y: The y position of the point.

Example

Libraries.Data.Formats.ScalableVectorGraphics.all

Polyline myLine
myLine:AddPoint(50,50)

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

Object o
Object t
integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

ConvertReservedCharacters(text value)

This action returns a new string that automatically converts any characters that are reserved in the HTML specification before placing them into the vector graphic. This prevents the graphic from not compiling in circumstances where a DataFrame created a graphic that used a reserved character.

Parameters

  • text value: the text to be converted

Return

text: A new text value with converted reserved characters.

Empty()

This action empties the list of points that construct the polyline.

Example

Libraries.Data.Formats.ScalableVectorGraphics.all

Polyline myLine
myLine:Empty()

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)
