Resized image becomes blurry

[aykutcan]

Hi.

I m working on a project that needs cropping, and resizing many times.

My main image size is 1000 x 400 px. When input is larger; i crop input image to 1000x400.
then resize it into 4 or 5 variations. im encoding input images to jpeg.

Problem is when i crop bigger picture its fine. When i resize cropped picture it becomes blurry.

For example
http://www.gereksiz.org/4189.jpg -> its Perfectly fine (1000x400)
http://www.gereksiz.org/4189-yatay.jpg -> Resized version. Blurry. (450x180)

im using

ImageMagick 6.7.2-7 2015-07-23 Q16 http://www.imagemagick.org
Php 5.5.30
on Centos (Production)

Imagick compiled with ImageMagick version ImageMagick 6.8.9-9 Q16 x86_64 2015-01-06
Imagick using ImageMagick library version ImageMagick 6.8.9-9 Q16 i686 2015-08-06
5.6.11-1ubuntu3 on Ubuntu 15.10 (My Virtual Server)

//JPEG on 100 quality
$tempFile->encode(iext(true), 100);
$return = $tempFile->save($file . iext());

foreach ($config["variations"] as $key => $var) {
    $tempVariationFile = $tempFile;
    $tempVariationFile->resize($var["width"], $var["height"]);
    $return = $tempVariationFile->save($file . '-' . $key . iext());
}

return $return;

iext(true) returns "jpg"
iext() returns ".jpg"

What am i doing wrong ?

Did you try adjusting the quality parameter on the save() call?
