public class IsometricPanel
extends GraphPanel

This generator creates three types of isometrically-scaled paper: lined-grid isometric, diamond grid and isometric dots. Line-grid isometric divides the surface of the paper into equilateral triangles: the horizontal distance between vertices equals each diagonal distance between vertices. Diamond-grid paper is the same is lined isometric but without the horizontals. (To create diamond-grid uncheck the '[]Show horizontals' Checkbox!). Isometric dots don't show the triangles, merely the vertices. A point is placed at each one.

If desired, a border can be drawn around the grid area. The border pen is selectable and will be used if the '[]Border pen' Checkbox is enabled. The line pen is used for horizontals and diagonals. Iso-dots paper uses CircleTag's 'point' method.

By default for lined paper the first (upper-leftmost) stroke will be diagonal down and the first iso-dot is in the upper left corner. Checking the '[]Offset first row' Checkbox changes this. The first diagonal stroke will be upward and the first iso-dot is offset horizontally by half a length.

Method Detail

drawGraph

public void drawGraph(int pTop,
                      int pBot,
                      int pLeft,
                      int pRight,
                      SVGTag pPaper)
Draw the paper.

Overrides:
drawGraph in class GraphPanel
Parameters:
pTop - The top margin of the drawable area.
pBot - The bottom margin of the drawable area.
pLeft - The left margin.
pRight - The right margin.
pPaper - The SVGTag on which the drawing is to occur.

reset

public void reset()
Restore factory values.

Overrides:
reset in class GraphPanel

setType

public void setType(boolean pIsLines)
Set the type of graph: lines or dots.

Parameters:
pIsLines - 'true' for a lined grid, 'false' for dots only.

setSize

public void setSize(double pSize)
Set the side length/dot spacing. Any value zero or less becomes 25.


setLines

public void setLines(int pPen,
                     boolean pHorizontals)
Set the pen used to draw the lines and enable/disable horizontal lines.

Parameters:
pPen - The line pen used to draw the grid.
pHorizontals - 'true' to enable horizontal lines, 'false' to leave them off.

setOffsetFirst

public void setOffsetFirst(boolean pOffset)
Enable/disable first-row offset. If 'true' the lines start with an upward diagonal and the dots start offset laterally.


setBorders

public void setBorders(boolean pEnable,
                       int pPen)
Enable/disable borders and set the border pen.


toPizza

public java.lang.String toPizza(java.lang.String pPrefix)
Description copied from class: GraphPanel

This method extracts the configuration and state information from a generator and produces java.util.Properties-style output. A String prefix can be prepended to each key. If 'pPrefix' is not null or blank it will be attached to the front of the key String, separated by a single dot. If the prefix does not end with a dot one will be supplied automatically.

Use of the prefix allows multiple configurations to be stored in a single file. Also, since each generator has its own unique prefix (separate from the one supplied) multiple generator configs can be stored in a single file.

This is primarily a scripting method. It was developed in order to allow the perfect settings to be saved in a (scripting-) language-agnostic way that was also human-readable. The individual property names are typically Java-fied versions of their GUI labels. If MathTools is run from its JAR and the standard GUI is present the instances exposed to scripts are the ones in the GUI, so setting values in the GUI will affect script output and settings made by the script are reflected in the GUI.

Specified by:
toPizza in class GraphPanel
Parameters:
pPrefix - The prefix to prepend to each key. Ignored if null or blank.

eatPizza

public void eatPizza(java.util.Properties pPizza,
                     java.lang.String pPrefix)
Description copied from class: GraphPanel

This method accepts a Properties object and an optional String prefix and attempts to extract configuration data from it. It complements toPizza(). If 'pPizza' is null or empty nothing happens: the method returns silently. If 'pPrefix' is not null or blank it is used as a prefix to each key. If the String sent in does not end with a dot one will be supplied automatically. All of the keys requested have default valus that match the ones on the GUI.

Under normal cirucmstances the generator instances exposed to scripts are the ones in the GUI so changes using one are reflected in the other.

Specified by:
eatPizza in class GraphPanel
Parameters:
pPizza - A java.util.Properties object containing configuration data.
pPrefix - An optional prefix to include with each key. Ignored if null or blank.
