Image is always at top in converted html from pdf

I am using following code and all contents of the specific pdf page are converting in a correct manner. But if there is any image in the middle of pdf page, that image in the HTML shows at the top.

PHP CODE:

umask(0);
$output = shell_exec('pdftohtml create.pdf create.html');

Edit:

Please check the pdf what I used for this: https://www.dropbox.com/s/6uy9wq27ff00n0x/create.pdf?dl=0

In this PDF, image is after 2 lines.

// Load the converted html page. shell_exec adds 's' to html file, creates.html

$html = file_get_contents('creates.html');
print_r($html);

// output

<!DOCTYPE html><html>

Now see

<img src="/var/www/html/pdf-sign/public/converted_path/create-1_1.png"/>

is just after at BODY tag. That means that image is gone to the top in replace of the third line.

Solution

  • I also faced this kind of problem. I got a solution. At first you need to convert pdf document to XML

    $output = shell_exec('pdftohtml -xml create.pdf create.xml');

    The XML output is like below 

    <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE pdf2xml SYSTEM "pdf2xml.dtd">
<pdf2xml producer="poppler" version="0.33.0">
<page number="1" position="absolute" top="0" left="0" height="1262" width="892">
<fontspec id="0" size="16" family="Times" color="#000000"/>
<image top="117" left="51" width="424" height="96" src="converted_path/create1.jpg"/>
<text top="57" left="99" width="144" height="16" font="0">Test document PDF</text>
</page>
</pdf2xml>

    Then you conver this string of XML into an object 

    $xml = simplexml_load_string($xmlContent);

    After that you need to measure the exact image place with the xml attributes top value like below 

    $pg = 0;
foreach($xml->page as $page) {
        foreach ($page as $e) {
            $all_attribute[$pg][(int)$e['top']] = $e;
        }
        $pg++;
    }

    After finding out all attributes top value sort the values based on array[key]

    foreach($all_attribute as $page) {
        ksort($page);
}

    When all the attributes are sorted based on xml top value, simply process the html like below

    foreach($xml->page as $page) {
  foreach($page as $p){
      if($p->getName() == 'image'){
         <img width="'.$p['width'].'" height="'.$p['height'].'" src="'.$p['src'].'" >
      }
  }
}

    I think it help you
    You can Also manage your text font
    xml stored all font in fontspec attribute and give an id

    <fontspec id="0" size="16" family="Times" color="#000000"/>

    and this id is call in text attribute font value

    <text top="57" left="99" width="144" height="16" font="0">

    now with the help of those values you need to process the font like below

    $font = [];
    foreach($xml->page as $page) {
        foreach ($page as $e) {
            if($e->getName() == 'fontspec'){
                $font[(int)$e['id']]['family'] = (string)$e['family'];
                $font[(int)$e['id']]['size'] = (string)$e['size'];
                $font[(int)$e['id']]['color'] = (string)$e['color'];
            }
        }
    }

    After that you need to process this font into html

    foreach($page as $p){
            if($p->getName() == 'text'){
                $ind = (int)$p['font'];
                $font_size = $font[$ind]['size'];
                $font_color = $font[$ind]['color'];
                $font_family = $font[$ind]['family'];
                '<span style="font-size:'.$font_size.'px;color:'.$font_color.';font-family:'.$font_family.'; font-weight: 900;">'.(string)$p.'</span>=';
          }
}
