<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); ?>
