| currentpoint |
() |
typedict.Path |
| |
Returns a
Point
that represents this path's current point, which for all practical
purposes can be thought of as the last point added to this path, or
NULL
if this path is empty.
Transformations that modify the
CTM
have no affect on the current point itself, but they do affect the
coordinates of the point returned by
currentpoint.
Applications often check the value returned by
currentpoint
when the need to know if a path is empty or not.

| Example: |
The program,
import yoix.stdio.*;
Path p;
Point pt;
p.moveto(50, 50);
p.lineto(50, 100);
printf("Output before CTM change:\n");
pt = p.currentpoint();
printf(" currentpoint=(%.1f, %.1f)\n", pt.x, pt.y);
p.CTM.scale(.5, .5);
printf("\nOutput after CTM change:\n");
pt = p.currentpoint();
printf(" currentpoint=(%.1f, %.1f)\n", pt.x, pt.y);
prints something like
Output before CTM change:
currentpoint=(50.0, 100.0)
Output after CTM change:
currentpoint=(100.0, 200.0)
on standard output.
Notice how the coordinates changed after we scaled the
CTM
associated with the path.
