[PC4P-users] Bug in setting the compression factor? And a possible fix

[Jason W. <pc...@gr...>]

I've been trying to use pc4p_set_compression() without success. Looking at 
the source code for pc4p_main.inc I found that pc4p_set_compression contains 
a bug:

------------------------------------------------------------------------
 function pc4p_set_compression( $compress )
 {
   if( $compress < 0 ) {
     $compress = 0;
   }
   elseif( $compress > 9 ) {
     $compress = 9;
   }
   else {
     die("Error: ".get_class( $this )." - ".$compress." is not a valid 
compression-factor");
   }
   pdf_set_value( $this->pdfp, "compress", $compress );
 }
------------------------------------------------------------------------

As it stands pdf_set_value() never gets called!

I have rewritten it as:


  function pc4p_set_compression($compress) {
    if (is_integer($compress)) {
      if ($compress < 0) {
        $compress = 0; }
      else {
        if ($compress > 9) {
          $compress = 9;
        }}
      pdf_set_value($this->pdfp, "compress", $compress); }
    else {
      die("Error: ".get_class($this)." - ".$compress." is not a valid 
compression-factor");
    }
  }


Incidentally what is the purpose of the compression factor? And what is the 
default? I have set it to 9, but the size of the PDF that I'm getting is the 
same as if I hadn't set the compression. However If I view the file in Adobe 
Acrobat then do a "Save As..." it results in a file that is 1/10th of the 
original size (from 4MB to 400KB).
