Method Detail

colorNames

public static java.lang.String[] colorNames()

Return a list of basic color names that are understood. Note that colors can also be specified using #rrggbb notation, where rr is the hex representation of the red component, etc. This method can be used to construct a dialog listing available colors symbolically by name.

Returns:

An array of symbolic color names.

createPaintedObject

public static PaintedObject createPaintedObject(java.lang.String type,
                                                java.lang.String attributes,
                                                java.lang.String content)

Create a new painted object. The element is parsed from two strings, the first being a representation of the element type, and the second being an XML-style attribute string. Any attributes that are not recognized will be ignored. Legal types and their attributes are:

Parameters:

type - The element type

attributes - An XML-style attribute string

content - The content

Returns:

a new painted object.

createPaintedObject

public static PaintedObject createPaintedObject(java.lang.String type,
                                                java.util.Map attributes,
                                                java.lang.String content)

Create a new painted object. The first argument is a string representation of the element type, and the second is a hash-table containing attributes of the object. Any attributes that are not recognized will be ignored. See the add(String, String) for a description of legal types and their attributes.

createPaintedObject

public static PaintedObject createPaintedObject(java.lang.String type,
                                                java.util.Map attributes)

Create a new painted object. The first argument is a string representation of the element type, and the second is a hash-table containing attributes of the object. Any attributes that are not recognized will be ignored. See the add(String, String) for a description of legal types and their attributes.

hashAttributes

public static void hashAttributes(java.lang.String s,
                                  java.util.Map map)

Given a XML-style attribute string and a hash-table, add each attribute and its value to the table.

FIXME: this sucks.

lookupColor

private static java.awt.Color lookupColor(java.lang.String color)
                                   throws java.lang.NumberFormatException

Given a string, return a color.

Throws:

java.lang.NumberFormatException

parseCoordString

private static double[] parseCoordString(java.lang.String s)

Parse a string of numbers into an array of double. The doubles can be delimited by commas and spaces.

processPaintedShapeAttributes

private static void processPaintedShapeAttributes(PaintedShape ps,
                                                  java.util.Map attributes)
                                           throws java.lang.NumberFormatException

Set the attributes of a PaintedShape from a hash-table

Throws:

java.lang.NumberFormatException

processPaintedPathAttributes

private static void processPaintedPathAttributes(PaintedPath pp,
                                                 java.util.Map attributes)
                                          throws java.lang.NumberFormatException

Set the attributes of a PaintedPath from a hash-table

Throws:
