Class PlotText

java.lang.Object
  visad.PlotText

public class PlotText
extends Object

PlotText calculates an array of points to be plotted to the screen as vector pairs, given a String and location, orientation and size in space.

The font is a simple one, and includes characters from the ASCII collating sequence from 0x20 thru 0x7E. Most of this was taken from the original visad.PlotText.

Convert a string of characters (ASCII collating sequence) into a series of triangles for drawing.

Parameters:

str - String to use

font - non-null font

start -

base -

up -

justification - is one of:

• TextControl.Justification.LEFT - Left justified text (ie: normal text)
• TextControl.Justification.CENTER - Centered text
• TextControl.Justification.RIGHT - Right justified text

verticalJustification - is one of:

• TextControl.Justification.TOP - Top justified text
• TextControl.Justification.CENTER - Centered text
• TextControl.Justification.BOTTOM - Bottom justified text (normal)

characRotation - is the angle (in degrees) at which each character in str is rotated with respect to the base line of the text. A positive value rotates the characters clockwise; a negative value rotates them counterclockwise.

scale - is the scaling factor.

offsets - is a 1x3 array defining the offsets in X, Y, Z, respectively.

Returns:

VisADTriangleArray of all the triangles needed to draw the characters in this string
