<b>Use this code to convert HEX colors to RGB that you can use with pdf_setrgbcolor:</b>

<?

$color = "#FF00FF";

$string = str_replace("#","",$color);

$red = hexdec(substr($string,0,2)) / 255;

$green = hexdec(substr($string,2,2)) / 255;

$blue = hexdec(substr($string,4,2)) / 255;

pdf_rect($pdf, 110, 600, 20, 30);

pdf_setrgbcolor_fill($pdf, $red, $green, $blue);

pdf_fill($pdf);

?>



This gives you a pink rectangle!

Here is a snippet of code to create a blue rectangle:



<?php



/*

*pdf_setrgbcolor(pdf_file, float red, float green, float blue);

*red/green/blue are values between 0 and 1.

*It appears that the value is supposed to be a percentage intensity.

*0.0 means a 0% intensity for that color (0 in RGB-scale)

*0.5 means a 50% intensity of that color (127 in RGB-scale)

*1.0 means a 100% intensity of that color (255 in RGB-scale)

*/



//Create blue rectangle

pdf_rect($pdf, 110, 600, 20, 30);

pdf_setrgbcolor_fill($pdf, 0, 0, 1.0);

pdf_fill($pdf);



?>
