Method Detail

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:

• line coords=vertex-list fill=color width=integer
• rectangle coords=x y width height fill=color outline=color width=integer
• ellipse coords=x y width height fill=color outline=color width=integer
• polygon coords=vertex-list fill=color outline=color width=integer
• text coords=x y fill=color font=font-name size=int style=bold|italic|plain

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)

Given a string, return a color.

parseCoordString

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

Parse a string of numbers into an array of double

processPaintedShapeAttributes

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

Set the attributes of a PaintedShape from a hash-table

processPaintedPathAttributes

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

Set the attributes of a PaintedPath from a hash-table

processPaintedStringAttributes

private static void processPaintedStringAttributes(PaintedString pp,
                                                   java.util.Map attributes)

Set the attributes of a PaintedString from a hash-table
