This section of the manual is really sparse, and there don't seem to be any tutorials out there that go beyond adding a single line of text, so I found this piece of information out by trial and error. The function only specifies that you want a rectangle at those co-ordinates, and must be followed by a stroke command: pdf_rect($pdf, 100, 100, 50, 50); pdf_stroke($pdf); This completes the process of placing the rectangle on the page.
Be sure of adding a pdf_stroke(resource_pdf) after the pdf_rect function or will take an error in the PDFlib.
Round rectangles My function to create rectangles width round corners: <?php function pdf_roundrect($pdfobj, $xpos, $ypos, $xsize, $ysize, $radius) { $ypos = $ypos+$ysize; pdf_moveto($pdfobj, $xpos, $ypos-$radius); pdf_lineto($pdfobj, $xpos, $ypos-$ysize+$radius); pdf_arc($pdfobj, $xpos+$radius, $ypos-$ysize+$radius, $radius, 180, 270); pdf_lineto($pdfobj, $xpos+$xsize-$radius, $ypos-$ysize); pdf_arc($pdfobj, $xpos+$xsize-$radius, $ypos-$ysize+$radius, $radius, 270, 360); pdf_lineto($pdfobj, $xpos+$xsize, $ypos-$radius); pdf_arc($pdfobj, $xpos+$xsize-$radius, $ypos-$radius, $radius,0,90); pdf_lineto($pdfobj, $xpos+$radius, $ypos); pdf_arc($pdfobj, $xpos+$radius, $ypos-$radius, $radius,90,180); } ?>
In php5 a rectangle with some text in is made like this. <?php $p->rect(55,520,400,20); $p->stroke(); $font = $p->load_font("Helvetica", "winansi", ""); $p->setfont($font, 14.0); $p->set_text_pos(200, 525); $p->show("Some text"); ?>
