By playing around with this you'll get a better understanding of what pdf_save and pdf_restore do.





<?php





//Create & Open PDF-Object


$pdf = pdf_new();


pdf_open_file($pdf);


pdf_set_info($pdf, "Author","Bob Nijman");


pdf_set_info($pdf, "Title","Sponsored by www.nijman.de");


pdf_set_info($pdf, "Creator", "See Author");


pdf_set_info($pdf, "Subject", "pdf_restore");


pdf_begin_page($pdf, 300, 300);








/*


By encapsulating the changes we make to the coordinate system


(pdf_translate() and pdf_rotate()) between pdf_save() and pdf_restore


we give these changes only local scope.


*/





/*


SMALL RECTANGLE


*/





pdf_save($pdf);


//move the origin of the coordinate system to (100,100)


pdf_translate($pdf, 100, 100);


//Rotate the coordinate system by 45 degrees.


pdf_rotate($pdf, 45);


//Draw a samll rectangle


pdf_rect($pdf, 0, 0, 20, 20);


pdf_stroke($pdf);


//Restore the graphics state to the way it was


//before we started to translate and rotate


pdf_restore($pdf);








/*


LARGER RECTANGLE


*/





pdf_save($pdf);


//move the origin of the coordinate system to (10,20)


pdf_translate($pdf, 10, 20);


//Rotate the coordinate system by 15 degrees.


pdf_rotate($pdf, 15);


//Draw a larger rectangle


pdf_rect($pdf, 0, 0, 40, 40);


pdf_stroke($pdf);


//Restore the graphics state to the way it was


//before we started to translate and rotate


pdf_restore($pdf);











//close it up


pdf_end_page($pdf);


pdf_close($pdf);


$data = pdf_get_buffer($pdf);


header('Content-type: application/pdf');


header('Content-disposition: inline; filename=nijman.pdf');


header('Content-length: ' . strlen($data));


echo $data;
