Karo Graph

• The Name textfield contains the name of the symbol.
• The Code textfield contains the sequential drawing commands. See below.
• The ASCII textfield denotes the character this symbol will be replaced with when exporting to TXT.
• When the Invert Black checkbox is checked, the symbol uses white instead of black as foreground color when black is the currently selected color. See below.
• When the Large checkbox is checked, the symbol is only drawn within every second gridpoint.

Drawing Code

The drawing code lets you define how symbols are drawn. The drawing commands each use one code line are executed sequenctially from top to bottom.

The coordinate system is a right handed system with positive x to the right and positive y to the top. One unit is the 18th part of a grid square (as defined in the Canvas Settings).

The possible drawing commands are the following:

Line      startX startY endX endY lineWidth strokeColor
Rect      top right bottom left lineWidth strokeColor fillColor
Circle    centerX centerY radius startAngle endAngle lineWidth strokeColor fillColor
Triangle  pos1X pos1Y pos2X pos2Y pos3X pos3Y lineWidth strokeColor fillColor

• Line: Draws a line from coordinates (startX, startY) to (endX, endY) with the given lineWidth.
• Rect: Draws a rectangle with boundary coordinates (top, right, bottom, left) with the given lineWidth.
• Circle: Draws a circle with center coordinates (centerX, centerY) with the given radius. The startAngle and endAngle are given in degrees and denote the angles within which the circle will be drawn with the given lineWidth.
• Triangle: Draws a triangle with the three coordinates (pos1X, pos1Y), (pos2X, pos2Y) and (pos3X, pos3Y) with the given lineWidth.
