cpdf_setlinejoin

Name

cpdf_setlinejoin — Sets line join type

Synopsis

bool cpdf_setlinejoin(pdfdoc, type); resource pdfdoc: PDF document identifier int type: Line join type

Returns

TRUE on success or FALSE on error

Description

Sets the type of join between two lines. These are normally only seen at large line widths although controlling how a line is joined can be useful for aesthetic reasons.

type can take values of 0, 1 or 2 which are:

`0`	Miter join. The outer edges of the joined lines continue until they meet at a point
`1`	Round join. Corners are rounded of with a diameter equal to the line width
`2`	Bevel join. The line caps are beveled off to form a straight edge acorss the top of the joined lines.

Version

Since versions 3.0.8 and 4.0

Example

$cpdf = cpdf_open(0, "test.pdf");

// create a 600x400 page

// set line widths to show effect
cpdf_setlinewidth($cpdf,5);

// show miter join
cpdf_setlinejoin($cpdf, 0);
cpdf_moveto($cpdf, 125, 650);
