Public Interface

CONSTRUCTOR Init;
Initializes a drawing style.

CONSTRUCTOR InitCopy(src: GPDrawingStyle);
Initializes a new drawing style, copying the style elements of src.

DESTRUCTOR Destroy;
Destroys a GPDrawingStyle.

FUNCTION Copy: GPDrawingStyleAsn;
Returns a new drawing style, copying the style elements of this drawing style.

PROCEDURE SetDrawingForeground (foreground: GPColor);
Sets the foreground color of objects to be drawn with this drawing style.

PROCEDURE GetDrawingForeground (VAR foreground: GPColor);
Returns the current drawing foreground color.

PROCEDURE SetDrawingMode (mode: GPDrawingMode);
Sets the mode of object to be drawn with this drawing style. There are two predefined values of GPDrawingMode. When GPxor is sent as the parameter to mode, it means that drawing will be done using pixel-XOR. That is, when a new shape (call it shape 1) is drawn and it overlaps an existing shape (shape 2), the overlap is drawn in a color that is a combination of shape 1's and shape 2's colors. In GPcopy mode, when shape 1 is drawn, all of shape 1's area, including the overlap with any other shape, is drawn in shape 1's color.

FUNCTION GetDrawingMode: GPDrawingMode;
Returns the current drawing mode (GPxor or GPcopy).

PROCEDURE SetLineStyle (style: GPLineStyle);
Sets the line style of objects to be drawn with this drawing style. There are five predefined values of GPLineStyle: PS_SOLID, PS_DASH, PS_DOT, PS_DASHDOT, and PS_DASHDOTDOT.

FUNCTION GetLineStyle: GPLineStyle;
Returns the current line style.

PROCEDURE SetLineWidth (width: integer);
Sets the line width of objects to be drawn with this drawing style.

FUNCTION GetLineWidth: integer;
Returns the current line width.
