Line
Line Draw a line a specified distance
#include <Quickdraw.h> Quickdraw
void Line(distHoriz, distVert );
short distHoriz ; distance, in pixels to draw horizontally
short distVert ; distance, in pixels to draw vertically
Line moves the pen a specified distance from its current location, drawing a
line as it is moved.
distHoriz is the distance, in pixels, to move the pen horizontally. Positive
values move to the right; negative to the left.
distVert is the distance, in pixels, to move the pen vertically. Positive
values move down; negative move up.
Returns: none
Notes: This is a quick way to draw a line with an endpoint a specified distance
from the current pen position. It is functionally identical to:
LineTo( thePort->pnLoc.h+distHoriz, thePort->pnLoc.v +distVert );
If the pen is visible (see ShowPen), the line is drawn in the current pen
size, pattern, foreground color, and transfer mode. Note that since the pen
pattern actually hangs below and to the right of the pen position, this and all
drawing operations may affect an area beyond horiz and vert .
While recording a polygon or region (see OpenPoly and OpenRgn), the
line created is infinitely thin and is not affected by the pen size, pattern, or
mode.
Use Move or MoveTo move the pen without drawing.
