Method Detail

findTextWidth

public static double findTextWidth(MapApp app,
                                   MapSet mapset,
                                   java.lang.String textStyle,
                                   java.lang.String text)

Calculates the pixel width of the passed String given the passed text style name, Mapset containing text style, and valid MapApp.

Checks for line breaks, returning only the longest width line of text.

Parameters:

app - - valid MapApp.

mapset - - MapSet containing text style.

textStyle - - String name of text style.

text - - String of text to find pixel width of.

Returns:

width of passed text in passed text style.

Throws:

java.lang.NullPointerException - if anything is null.

                                    MapSet mapset,
                                    java.lang.String textStyle,
                                    java.lang.String text)

Calculates the pixel height of the passed String given the passed text style name, Mapset containing text style, and valid MapApp.

Parameters:

app - - valid MapApp.

mapset - - MapSet containing text style.

textStyle - - String name of text style.

text - - String of text to find pixel height of.

Returns:

height of passed text in passed text style.

public static java.awt.geom.Rectangle2D findTextBounds(MapApp app,
                                                       MapSet mapset,
                                                       java.lang.String textStyle,
                                                       java.lang.String text)

Calculates the pixel bounds of the passed String given the passed text style name, Mapset containing text style, and valid MapApp.

Parameters:

app - - valid MapApp.

mapset - - MapSet containing text style.

textStyle - - String name of text style.

text - - String of text to find pixel bounds of.

Returns:

bounds of passed text in passed text style.

Throws:

java.lang.NullPointerException - if anything is null.
