cpdf_save — Saves current enviroment


bool cpdf_save(pdfdoc);
resource pdfdoc: PDF document identifier


TRUE on success or FALSE on error


Saves the current graphical state of the PDF document. This includes graphics parameters such as clipping path, coordinate system, current point, dash pattern, flatness, line cap style, line join style, line width, miter limit and color parameters like fill and stroke colors. In addition, some PDF parameters are saved including character spacing, word spacing, horizontal scaling, leading, font, fontsize, text rendering and text rise.

In the example below, try commenting out the lines calling cpdf_save() and cpdf_restore() to measure the effect of saving and restoring the environment.


Since versions 3.0.8 and 4.0


Example 148. Save and restore text state

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

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

// display text in document
cpdf_set_font($cpdf, "Helvetica", 15, "WinAnsiEncoding");
cpdf_set_text_pos($cpdf, 50, 300);
cpdf_show($cpdf, "This is horizontal text");

// save the current document state

// move and rotate the coordinate system
cpdf_translate($cpdf, 20, 20); 
cpdf_rotate($cpdf, 90); 

// move drawing position
cpdf_set_text_pos($cpdf, 10, 10);

// display text
cpdf_show($cpdf, "vertical text");

// restore the documents previous state

// draw more horizontal text
// note use of cpdf_continue_text() for effect
cpdf_set_leading($cpdf, 15);
cpdf_continue_text($cpdf, "horizontal text continues");


// close and write document
