<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!

*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)
