Method Detail

createSVGDoc

public static org.w3c.dom.svg.SVGDocument createSVGDoc()

Create an SVG Document using a default DOM implementation.

Returns:

An SVG Document with default settings

getSVGFontMetrics

public static FontMetrics getSVGFontMetrics(Font font)

TransferGraphicsToDocument

public static void TransferGraphicsToDocument(org.w3c.dom.svg.SVGDocument doc,
                                              Dimension canvasdimension,
                                              org.apache.batik.svggen.SVGGraphics2D g)

Transfer data that was writen to an SVGGraphics2D context to a document using a specified canvasdimension.

Parameters:

doc - - the SVGDocument to write to.

canvasdimension - - the target canvas dimension (can be null, in which instance default sizes are used (400/290)

g - - The SVGGraphics2D Context to write in.

scaleSVGFont

public static Font scaleSVGFont(Dimension dim,
                                Font font,
                                String label)

Scale a Font so that a given label fits into a specific dimension in an SVG context.

Parameters:

dim - - the dimension the label should fit in.

font - - the font to scale.

label - - the String that should fit into the dimension.

Returns:

the font scaled to the provided Dimension using a default svg graphics context

scaleFont

public static Font scaleFont(Dimension dim,
                             Font font,
                             Graphics g,
                             String label)

Scale a Font so that a given label fits into a specific dimension.

Parameters:

dim - - the dimension the label should fit in.

font - - the font to scale.

g - - the graphics context to use

label - - the String that should fit into the dimension.

Returns:

the font scaled to the provided Dimension

getLabelsForData

public static HashMap<Comparable,String> getLabelsForData(Vector<Comparable> entries)

Get alphanumeric unique labels for a set of entries (i.e. for labeling items or similar things) This function provides the same labels when called with the same entries

Parameters:

entries - - Comparable objects (not necessarily of the same type)

Returns:

a Mapping of the provided objects to alphanumeric labels.
