Class IltLineStyle

java.lang.Object
  ilog.tgo.grprim.IltLineStyle

All Implemented Interfaces:

IlLineStyle, Serializable

Direct Known Subclasses:

IltLineStyle.LineStyleWrapper, IltLineStyle.Solid

public abstract class IltLineStyle
extends Object
implements IlLineStyle

This class describes a pattern with which a 1D line can be filled.

When a line is drawn, the pattern is drawn in the foreground color, and the remainder of the line is drawn in the background color. If the background color is null, it means that the line is transparent.

Nested Class Summary

static class	IltLineStyle.LineStyleWrapper A line style which: for thin lines makes an indirection to another IlLineStyle, for thick lines fills all pixels in the foreground color.
static class	IltLineStyle.Solid Describes a line style which fills all pixels in the foreground color.

Field Summary

drawThickLine

public abstract double drawThickLine(Graphics g,
                                     ilog.tgo.grprim.internal.IltStrip s,
                                     ilog.tgo.grprim.internal.IltLine halfplane1,
                                     ilog.tgo.grprim.internal.IltLine halfplane2,
                                     ilog.tgo.grprim.internal.IltLine halfplaneB1,

                                     Color foreground,
                                     Color background,
                                     double offset)

Draws a thick line. More precisely, this fills a trapezoid bounded by s, halfplane1, halfplane2, halfplaneB1 and halfplaneB2.

Parameters:

s - the strip which is to be filled

halfplane1 - starting line

halfplane2 - end line

halfplaneB1 - bevel delimiter 1

halfplaneB2 - bevel delimiter 2

foreground - foreground color

background - background color, or null

offset - the starting pixel within the pattern (>=0, < getPeriod())

Returns:

the next pixel within the pattern

NewAlternatingLineStyle

public static IltLineStyle NewAlternatingLineStyle(double[] dashes)

Deprecated. Please use the method that takes a float array argument instead.

Returns a new alternating line style. This sets a number of pixels in the foreground color, then a number of pixels in the background color, and so on. When the given array is exhausted, restart from the beginning.

Parameters:

dashes - A non-empty array of positive numbers. The first number is the number of pixels in the foreground color, the second is the number of pixels in the background color, the third number is the number of pixels in the foreground color, and so on.

Deprecated Since:

JTGO 4.0

NewAlternatingLineStyle

public static IltLineStyle NewAlternatingLineStyle(float[] dashes)

Returns a new alternating line style. This sets a number of pixels in the foreground color, then a number of pixels in the background color, and so on. When the given array is exhausted, restart from the beginning.

Parameters:

dashes - A non-empty array of positive numbers. The first number is the number of pixels in the foreground color, the second is the number of pixels in the background color, the third number is the number of pixels in the foreground color, and so on.

Since:

JTGO 4.0

GetAlternatingLineStyle

public static float[] GetAlternatingLineStyle(IlLineStyle lstyle)

Internal method or field: do not use!

GetAlternatingLineStyle

public static IltLineStyle GetAlternatingLineStyle(float[] dashes)

Returns a line style with the given configuration if it exists. If a line style does not exist, one is created and returned.

Since:

JTGO 4.0
