If you encounter errors of the form function 'PDF_setcolor' must not be called in 'path' scope this generally means that you've called the PDFLib functions in the wrong order. For example, the following would be *incorrect* because PDF_rect marks the beginning of the "path scope", and set_color must not be called in path scope:

<?php

// THIS CODE WILL PRODUCE AN ERROR
PDF_rect($pdf,0,0,$width,$height);
PDF_setcolor($pdf,$red,$green,$blue);
PDF_fill($pdf);
<
p>The correct order of function calls is as follows:
<
p>// Correct order of function calls
PDF_setcolor($pdf,$red,$green,$blue);
PDF_rect($pdf,0,0,$width,$height);
PDF_fill($pdf);

?>

If you want to change the font color you need to set type to  "fill", not "stroke" ("both" also works, of course).

Bonjour,

Cette fonction est utilisable pour d?finir une couleur de police.

Hello,

I search for the way of setting colors for the font in pdf and I find this.
Hope it could help.

<?php
/**
*    set font color
*    maurice.anglebert@free.fr
*/

// path for the pdf file and string to show
$pdfFilePath $_SERVER[DOCUMENT_ROOT]."/the_dir_of_the_file/test.pdf";
$string "The new color of my font";

$pdf pdf_new();
pdf_open_file($pdf$pdfFilePath);
pdf_set_info($pdf"Title""Test pdf");
// A4 page
pdf_begin_page($pdf595842);

// set up of the font
$font pdf_findfont($pdf"Courier""host"FALSE); 
    if (isset(
$font)) { 
       
pdf_setfont($pdf$font10) or die ("unknown font"); 
    } 

pdf_setColor($pdf"fill""rgb",001); 
// this for blue color 
// pdf_setColor($pdf, "fill", "rgb",1, 0, 0) for red

pdf_set_value($pdf"textrendering"0);
// show at the top of the page center
pdf_show_boxed($pdf$string083259510"center""");

// resets graphic state
pdf_initGraphics($pdf);
// end of page and pdf_object 
pdf_end_page($pdf); 
pdf_close($pdf);
pdf_delete($pdf);

// use header to get the file
header("Content-type: application/pdf");
header("Content-length: ".filesize($pdfFilePath));
header("Content-disposition: inline; filename=test.pdf");
readfile($pdfFilePath);   
?>

Here's a function for converting HTML hexadecimal colors to RGB decimals suitable for this function:

$color_hex = "FF0000";       ## whatever hex color you want
$color = convert_hexcolor_rgbdec($color_hex);
pdf_setcolor($pdf, 'fill', 'rgb', $color['r'], $color['g'], $color['b']);

function convert_hexcolor_rgbdec($color_hex)
{
   $color['r'] = hexdec(substr($color_hex, 0, 2))/255; 
   $color['g'] = hexdec(substr($color_hex, 2, 2))/255; 
   $color['b'] = hexdec(substr($color_hex, 4, 2))/255;
   return $color;
}

Here's a better implementation for setting HTML hexadecimal colors:

function pdf_setcolor_hex($hexcolor, $type = '')
{
    global $pdf;     ## match this to your pdf resource handle
       $color['r'] = hexdec(substr($hexcolor, 0, 2))/255; 
       $color['g'] = hexdec(substr($hexcolor, 2, 2))/255; 
       $color['b'] = hexdec(substr($hexcolor, 4, 2))/255;
       if ($type != 'fill' && $type != 'stroke')  $type = 'both';
       pdf_setcolor($pdf, $type, 'rgb', $color['r'], $color['g'], $color['b']);
}

Sample usage:
pdf_setcolor_hex('FFFFFF', 'fill');

This seems a little less complicated:

this is the color you want to use : 'FF11AA'

<?php
pdf_setcolor 
($pdf'both'0xFF 2550x11 2550xAA 255);
?>

Damn, this took me some real long time! Maybe it's helpfull for those who even have no idea of color-Schemes like me ;)

If u want to generate PDF's for Print Offices u need to set all the colors in CMYK.

Here is a Function that will convert RGB to CMYK

<?
function hex2rgb($hex) {
 
$color str_replace('#','',$hex);
 
$rgb = array('r' => hexdec(substr($color,0,2)),
               
'g' => hexdec(substr($color,2,2)),
               
'b' => hexdec(substr($color,4,2)));
  return 
$rgb;
}

function 
rgb2cmyk($var1,$g=0,$b=0) {
   if(
is_array($var1)) {
     
$r $var1['r'];
     
$g $var1['g'];
     
$b $var1['b'];
   }
   else 
$r=$var1;
   
$cyan    255 $r;
   
$magenta 255 $g;
   
$yellow  255 $b;
   
$black   min($cyan$magenta$yellow);
   
$cyan    = @(($cyan    $black) / (255 $black)) * 255;
   
$magenta = @(($magenta $black) / (255 $black)) * 255;
   
$yellow  = @(($yellow  $black) / (255 $black)) * 255;
   return array(
'c' => $cyan 255,
               
'm' => $magenta 255,
               
'y' => $yellow 255,
               
'k' => $black 255);
}

$color=rgb2cmyk(hex2rgb('#FF0000')); 
pdf_setcolor($pdf"both""cmyk"$color['c'], $color['m'], $color['y'], $color['k']);
?>

U can call it with parameters (r,g,b) or just an array(r,g,b) that contains these values.

Hope it works correct. All testing was fine.

Here is a quick snippet to convert CMYK to RGB. It has better precision than a lot of other solutions that also don't factor in colour profiles.

<?php

$cmyk 
'10,20,100,31';
list(
$c$m$y$k) = explode(','$cmyk);

# Gets the rgb as floats (cast via (int) if you want int )
$r = (min(($c 100) * ($k /= 100) + $k1)) * 255;
$g = (min(($m 100) * ($k) + $k1)) * 255;
$b = (min(($y 100) * ($k) + $k1)) * 255;

echo 
"$r $g $b\r\n";

# Converts the rgb to hex with leading 0's
$r str_pad(dechex($r), 2'0'STR_PAD_LEFT);
$g str_pad(dechex($g), 2'0'STR_PAD_LEFT);
$b str_pad(dechex($b), 2'0'STR_PAD_LEFT);

echo 
"hex: $r$g$b\r\n";

/* an example to see the colour via html
echo '<div style="width: 80px; height: 80px; background-color: #', "$r$g$b", '"></div>';
*/
?>
