Imagick not returning the image resolution

Question

for attached kind of images Imagick not returning resolution(Getting only height and width)

Here is my code.

$image = new Imagick($tempPath);
$resolutions = $image->getImageResolution();
$imageGeometry = $image->getImageGeometry();
if ($ext == 'bmp' || $ext == 'png') {
                        $xresolution = $resolutions['x'] * 2.54;
                        $yresolution = $resolutions['y'] * 2.54;
                    } else {
                        $xresolution = $resolutions['x'];
                        $yresolution = $resolutions['y'];
                    }
$msg = array("status" => "success", "imageHeight" => $imageGeometry['height'], "imageWidth" => $imageGeometry['width'], "HorizontalResolution" => $xresolution, "VerticalResolution" => $yresolution);

Answer 1

I ran this:

#!/usr/local/bin/php -f
<?php
$image = new Imagick("thing.jpg");
$resolutions = $image->getImageResolution();
$imageGeometry = $image->getImageGeometry();
var_dump($resolutions);
var_dump($imageGeometry)
?>

And got this, which looks correct to me:

array(2) {
  ["x"]=>
  float(72)
  ["y"]=>
  float(72)
}
array(2) {
  ["width"]=>
  int(2362)
  ["height"]=>
  int(1476)
}

You don't say what you got, nor what you expected. Maybe check your software is correctly installed and up-to-date.
