Hi,

Using replaceVariableByHTML(), I'm trying to insert a simple 3 columns table, with a scaled image inside each cell. No matter what (HTML tags or CSS styles), the images doesn't scale in the resulting DOCX. How can I achieve this:

     $docx = new CreateDocxFromTemplate('htmltest.docx');
        $pdm = <<<EOT
                <table width="100%">
                        <tr>
                                <td width="33%" ><img width="75%" src="image1.png"></td>
                                <td width="33%" ><img width="75%" src="image2.png"></td>
                                <td width="33%" ><img width="75%" src="image3.png"></td>
                        </tr>
                </table>
EOT;

        $docx->replaceVariableByHTML('PDM', 'block', $pdm, array('isFile' => false, 'parseFloats' => true, 'parseDivsAsPs' => false, 'downloadImages' => true));
        $docx->createDocx('htmltest_out');         

Thank you very much,

PdR

Hello,

You need to set width value without px or %. For example:

<td width="33%" ><img width="50" src="image.png"></td>

Since HTML5, width and height values in this tag must be in pixels and without adding 'px' (http://www.w3schools.com/tags/att_img_width.asp).

We also recommend you to check that Tidy is installed and running on your server.

Regards.

Hello,

Thanks for your answer.

My goal is to scale the image relative to the width of the column; problem is, using CSS doesn't work either:

     $docx = new CreateDocxFromTemplate('htmltest.docx');
        $pdm = <<<EOT
<table width="100%">
        <tr>
                <td width="33%" ><img style="width:75%" src="image1.jpg"></td>
                <td width="33%" ><img style="width:75%" src="image2.jpg"></td>
                <td width="33%" ><img style="width:75%" src="image3.png"></td>
        </tr>
</table>
EOT;

        $docx->replaceVariableByHTML('PDM', 'block', $pdm, array('isFile' => false, 'parseFloats' => true, 'parseDivsAsPs' => true, 'downloadImages' => true));
        $docx->createDocx('htmltest_out');

Hello,

phpdocx doesn't support % sizing in images, only fixed sizes (or auto) for both width and height values.

Regards.

So... is there a way I can get the width, in pixels, of the paragraph where the table would occur? With that in hands, I could easily calculate the fit for the images.

Thanks

Hello,

Due to how Word works is not advisable setting image sizes as percent. We recommend you to use px for all sizes, because if you use % you don't know the final sizing until the document is opened.

Anyway, if you want to test a beta patch, please edit the HTML2WordML.inc file and in line 1022 add these lines:

if (isset($nodo['attributes']['width'])) {
  $widthUnit = preg_replace('/\d+/', '', $nodo['attributes']['width']);
    if ($widthUnit == '%') {
      $widthValue = preg_replace('/[^\d]+/', '', $nodo['attributes']['width']);
      $cx = $cx * $widthValue / 100;
    }
  }

  if (isset($nodo['attributes']['height'])) {
    $heightUnit = preg_replace('/\d+/', '', $nodo['attributes']['height']);
    if ($widthUnit == '%') {
      $heightUnit = preg_replace('/[^\d]+/', '', $nodo['attributes']['height']);
      $cy = $cy * $widthValue / 100;
  }
}

Instead of:

$c = $this->getImageDimensions($size, $imageSize);
$cx = $c[0];
$cy = $c[1];

self::$WordML .= $this->generateImageRPr($properties, $cy);

self::$openTags[$depth] = $nodo['nodeName'];

the code must be:

$c = $this->getImageDimensions($size, $imageSize);
$cx = $c[0];
$cy = $c[1];

if (isset($nodo['attributes']['width'])) {
    $widthUnit = preg_replace('/\d+/', '', $nodo['attributes']['width']);
    if ($widthUnit == '%') {
        $widthValue = preg_replace('/[^\d]+/', '', $nodo['attributes']['width']);
        $cx = $cx * $widthValue / 100;
    }
}

if (isset($nodo['attributes']['height'])) {
    $heightUnit = preg_replace('/\d+/', '', $nodo['attributes']['height']);
    if ($widthUnit == '%') {
        $heightUnit = preg_replace('/[^\d]+/', '', $nodo['attributes']['height']);
        $cy = $cy * $widthValue / 100;
    }
}

self::$WordML .= $this->generateImageRPr($properties, $cy);

self::$openTags[$depth] = $nodo['nodeName'];

It's a beta patch but works for HTML such as:

<table width="100%">
    <tr>
        <td width="33%"><img width="33%" src="image1.png"></td>
        <td width="33%"><img width="33%" src="image2.png"></td>
        <td width="33%"><img width="33%" src="image3.png"></td>
    </tr>
</table>

But we highly recommend using fixed sizes or use the addTable method instead of HTML for this kind of tasks.

Regards.
