cpdf_rotate — Rotates of an object


bool cpdf_rotate(pdfdoc, angle);
resource pdfdoc: PDF document identifier
double angle: Angle of rotation


TRUE on success or FALSE on error


Rotates an object through angle degrees. The initial point of rotation is about the last drawing point which is either 0,0 or defined by cpdf_translate() or cpdf_moveto() . If performing mutiple rotations as per the example below, the next angle of rotation is taken from the current drawing position which is the previously drawn shape.


Since versions 3.0.8 and 4.0


Example 146. Draw a pattern of rectangles

// 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 point of rotation
cpdf_translate($cpdf, 200, 300);

// draw a 10 squares and rotate each time square is drawn
for ($i1; $i<18; $i++) {
    cpdf_rect($cpdf, 30, 30, 30, 30);
    cpdf_rotate($cpdf, 20);

// close and write document
