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);
}
?>

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.
