cpdf_setlinecap

Name

cpdf_setlinecap — Sets linecap type

Synopsis

bool cpdf_setlinecap(pdfdoc, type); resource pdfdoc: PDF document identifier int type: Line cap type

Returns

TRUE on success or FALSE on error

Description

Sets the type of cap a line should have. These are normally only seen at large line widths although controlling how a line is squared off may be useful when drawing complex shapes or tables.

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

`0`	Butt end caps. The stroke is squared off exactly at the end of the line
`1`	Round caps. The lines are rounded off with a half circle which has a diamter equal to the line width
`2`	Projecting caps. The ends of the line are square but the ends of the line move beyond the end of the stroke by a distance of half the line width

Version

Since versions 3.0.8 and 4.0

Example

Example 171. Show different line caps

// start a PDF document
$cpdf = cpdf_open(0, "test.pdf");

// create a 600x400 page
cpdf_page_init($cpdf, 1, 0, 600, 400, 1);

// set the linewidth to show effect of cap
cpdf_setlinewidth($cpdf,5);

// butt end caps
cpdf_setlinecap($cpdf, 0);
cpdf_moveto($cpdf, 10, 550);
cpdf_lineto($cpdf, 350, 550);
cpdf_stroke($cpdf);

// round caps
cpdf_setlinecap($cpdf, 1);
cpdf_moveto($cpdf, 10, 530);
cpdf_lineto($cpdf, 350, 530);
cpdf_stroke($cpdf);

// projecting caps
cpdf_setlinecap($cpdf, 2);
cpdf_moveto($cpdf, 10, 510);
cpdf_lineto($cpdf, 350, 510);
cpdf_stroke($cpdf);

// close and write document
