cpdf_curveto — Draws a curve


bool cpdf_curveto(pdf, x1, y1, x2, y2, x3, y3[, mode]);
int pdf: PDF object identifier
double x1: First x coordinate
double y1: First y coordinate
double x2: Second x coordinate
double y2: Second y coordinate
double x3: Third x coordinatee
double y3: Third y coordinate
int mode (optional): Units mode


TRUE on success or FALSE on error


Draws a bezier curve to x3 , y3 from from the current drawing point. Points x1 , y1 and x2 , y2 are the control points and define the shape of the curve. Don't forget to stroke your shape using pdf_stroke() .

If mode is specified, coordinates are calculated in PostScript points. There are usually 72 PostScript points to an inch. If not specified or set to 0, then the pages default units are used.


Since versions 3.0.6 and 4.0


Example 126. Draw two filled curves

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

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

// move pointer
cpdf_moveto($cpdf, 300, 100, 1);

// draw first curve and stroke
cpdf_lineto($cpdf, 350, 100, 1);
cpdf_curveto($cpdf, 350, 100, 325, 300, 300, 100, 1);

// move pointer again  
cpdf_moveto($cpdf, 200, 50, 1);

// draw second shape and stoke/fill
cpdf_lineto($cpdf, 250, 50, 1);
cpdf_curveto($cpdf, 250, 50, 225, 200, 200, 50, 1);
