Class TextPath

java.lang.Object

org.gvsig.symbology.fmap.mapcontext.rendering.legend.styling.TextPath

public class TextPath
extends java.lang.Object

Class that represents baseline of a string and allows the baseline to be composed as contiguous segments with distinct slope each.

Once a TextPath is created for a string it is possible to know where the character at a determined position in the string is placed and rotated.

Constructor Detail

TextPath

public TextPath(java.awt.Graphics2D g,
                Geometry path,
                char[] text,
                java.awt.Font font,
                float characterSpacing,
                float characterWidth,
                boolean kerning,
                float leading,
                int alignment,
                float wordSpacing,
                float margin,
                boolean rightToLeft)

Creates a new instance of TextPath with the current graphics context.

Given a Graphics2D, TextPath can know which Font and FontRenderContext is in use. So, it can calculate the position and rotation of each character in char[] text based in the path defined by the FShape path argument.

Parameters:

g, - Graphics2D

path, - FShape

text, - char[]

Method Detail

softenShape

protected Geometry softenShape(Geometry shape,
                               java.awt.font.GlyphVector gv)
                        throws CreateGeometryException

Throws:

CreateGeometryException

nextPosForGlyph

public double[] nextPosForGlyph(int glyphIndex)

Returns the placement of the next character to draw and the corresponding rotation in a double array of three elements with this order:

double[0] Position in X in the screen

double[1] Position in Y in the screen

double[2] Angle of the character.

Returns:

getGlyphCount

public int getGlyphCount()

isWordSeparator

protected static boolean isWordSeparator(char c,
                                         char[] wordSeparators)
