CairoContext::getCurrentPoint -- cairo_get_current_point — The getCurrentPoint purpose
Object oriented style
Procedural style
Gets the current point of the current path, which is conceptually the final point reached by the path so far.
The current point is returned in the user-space coordinate system. If there is no defined current point or if cr is in an error status, x and y will both be set to 0.0. It is possible to check this in advance with CairoContext::hasCurrentPoint().
Most path construction functions alter the current point. See the following for details on how they affect the current point: CairoContext::newPath(), CairoContext::newSubPath(), CairoContext::appendPath(), CairoContext::closePath(), CairoContext::moveTo(), CairoContext::lineTo(), CairoContext::curveTo(), CairoContext::relMoveTo(), CairoContext::relLineTo(), CairoContext::relCurveTo(), CairoContext::arc(), CairoContext::arcNegative(), CairoContext::rectangle(), CairoContext::textPath(), CairoContext::glyphPath().
Some functions use and alter the current point but do not otherwise change current path: CairoContext::showText().
Some functions unset the current path and as a result, current point: CairoContext::fill(), CairoContext::stroke().
An array containing the x (index 0) and y (index 1) coordinates of the current point.
Example #1 Object oriented style
<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->moveTo(10, 10);
var_dump($c->getCurrentPoint());
?>
The above example will output something similar to:
array(2) {
[0]=>
float(10)
[1]=>
float(10)
}
Example #2 Procedural style
<?php
$s = cairo_image_surface_create(CAIRO_SURFACE_TYPE_IMAGE, 100, 100);
$c = cairo_create($s);
cairo_move_to($c, 10, 10);
var_dump(cairo_get_current_point($c));
?>
The above example will output something similar to:
array(2) {
[0]=>
float(10)
[1]=>
float(10)
}
