CairoContext::getCurrentPoint -- cairo_get_current_point — The getCurrentPoint purpose
Object oriented style (method):
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)
}
