'image converted from pdf file with Imagick got grey background

I'm trying to convert a pdf file to image with imagick in php. The script works fine but the image created has a grey background like if the background of the pdf file is removed

$srcimg = $_SERVER['DOCUMENT_ROOT'] . '/files/pdf_canevas/doc1.pdf'; 

$targetimg = $_SERVER['DOCUMENT_ROOT'] . '/files/pdf_canevas/doc1.jpeg'; 

$im = new imagick();
$im->setResolution(150, 150);
$im->readImage($srcimg);
$im->setImageFormat('jpeg');
$im->setImageCompression(imagick::COMPRESSION_JPEG); 
$im->setImageCompressionQuality(100);
$im->writeImage($targetimg);

$im->clear();
$im->destroy();

this is an exemple of background i got on the conversion image enter image description here
