CairoContext::moveTo -- cairo_move_to — The moveTo purpose
Object oriented style (method):
$x
, string $y
)Procedural style:
Begin a new sub-path. After this call the current point will be (x, y).
contextA valid CairoContext object.
xThe x coordinate of the new position.
yThe y coordinate of the new position
No value is returned.
Example #1 Object oriented style
<?php
$s = new CairoImageSurface(CairoFormat::ARGB32, 100, 100);
$c = new CairoContext($s);
$c->setSourceRgb(0, 0, 0);
$c->paint();
// Move 10 pixels across, and 10 pixels down
$c->moveTo(10, 10);
$c->lineTo(90, 90);
$c->setLineWidth(2);
$c->setSourceRgb(1, 1, 1);
$c->stroke();
// Move 90 pixels across, and 10 pixels down
$c->moveTo(90, 10);
$c->lineTo(10, 90);
$c->setLineWidth(2);
$c->setSourceRgb(1, 1, 1);
$c->stroke();
$s->writeToPng(dirname(__FILE__) . '/CairoContext_moveTo.png');

Example #2 Procedural style
