Class IltLineStyle.LineStyleWrapper

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

All Implemented Interfaces:

IlLineStyle, Serializable

Enclosing class:

IltLineStyle

public static class IltLineStyle.LineStyleWrapper
extends IltLineStyle

A line style which:

• for thin lines makes an indirection to another IlLineStyle,
• for thick lines fills all pixels in the foreground color.

Method Detail

getPeriod

public double getPeriod()

Description copied from interface: IlLineStyle

Returns the periodicity of the pattern.

pixelColor

public int pixelColor(double offset)

Description copied from interface: IlLineStyle

Returns the color for a given offset.

Returns:

0 for background, 1 for foreground.

                       Color background,
                       double offset)

Description copied from interface: IlLineStyle

Draws a line of thickness 1.

Parameters:

g - The Graphics where the line will be drawn.

x1 - Starting point of the line.

y1 - Starting point of the line.

x2 - End point of the line.

y2 - End point of the line.

foreground - Foreground color.

background - Background color or null.

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

Returns:

The next pixel within the pattern.

                            Color background,
                            double offset)

Description copied from class: IltLineStyle

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

Specified by:

drawThickLine in class IltLineStyle

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

hashCode

public int hashCode()

Overrides:

hashCode in class Object
