CAIRO_TEXT_PATH(3) 1 CAIRO_TEXT_PATH(3)CairoContext::textPath - The textPath purpose
Object oriented style
SYNOPSIS
public void CairoContext::textPath (string $string)
DESCRIPTION
Procedural style
void cairo_text_path (CairoContext $context, string $text)
Adds closed paths for text to the current path. The generated path, if filled, achieves an effect similar to that of CairoContext::show-
Text.
Text conversion and positioning is done similar to CairoContext::showText.
Like CairoContext::showText, after this call the current point is moved to the origin of where the next glyph would be placed in this same
progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for chaining
multiple calls to CairoContext::showText without having to set current point in between.
Note: The CairoContext::textPath function call is part of what the cairo designers call the "toy" text API. It is convenient for short
demos and simple programs, but it is not expected to be adequate for serious text-using applications. See CairoContext::glyphPath for the
"real" text path API in cairo.

CAIRO_GET_CURRENT_POINT(3) 1 CAIRO_GET_CURRENT_POINT(3)CairoContext::getCurrentPoint - The getCurrentPoint purpose
Object oriented style
SYNOPSIS
public array CairoContext::getCurrentPoint (void )
DESCRIPTION
Procedural style
array cairo_get_current_point (CairoContext $context)
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: CairoCon-
text::newPath, CairoContext::newSubPath, CairoContext::appendPath, CairoContext::closePath, CairoContext::moveTo, CairoContext::lineTo,
CairoContext::curveTo, CairoContext::relMoveTo, CairoContext::relLineTo, CairoContext::relCurveTo, CairoContext::arc, CairoContext::arcNeg-
ative, 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.
PARAMETERS
o $context
- A valid CairoContext object.
RETURN VALUES
An array containing the x (index 0) and y (index 1) coordinates of the current point.
EXAMPLES
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)
}
