Using saveImage on PDF makes background black about pdf-to-image HOT 10 CLOSED

You loop through the PDF pages to save each page individually.

for ($i = 1; $i <= $pdf->getNumberOfPages(); $i++) {
    $pdf->setPage($i)->setOutputFormat('png')->saveImage('path/to/image.png');
}

You can in turn also decide yourself what page number you want to save.

$i = 1;
$pdf->setPage($i)->setOutputFormat('png')->saveImage('path/to/image.png');

Probably something to do with transparency yes...

I'd accept a PR that fixes this.

Figured this happens when the PDF has multiple pages and you try to save it without looping through the pages.

Thanks for this, that i have already did, but can't save single image with all pages images is there any way for this.

Thanks for your help so far.

i did a short look, and as i can see Imagick is used, try to use
flattenImages(); that should do the trick

from pdf-to-image.

flattenImages() was just removed as i can see, now it's
$image->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN);

from pdf-to-image.

Same issue persists (transparent background) when trying to save as PNG

was able to fix by forcing this:
Pdf.php:

public function getImageData($pathToImage) {
...
$imagick->transparentPaintImage('#FFFFFF',1,1, 'normal'); // added this
$imagick->mergeImageLayers(\Imagick::LAYERMETHOD_FLATTEN);
...
}

fyi: http://phpimagick.com/Imagick/transparentPaintImage

Closing this for now, I accept PR's that make this package more stable.
