Wrong colors used in output.jpg

[OskarStark]

Hi Guys!
I'm using PHP 5.5 and tried Gmagick, Imagick and GD

Start with this image `ìnput.jpg`` (800x1200px) - color is CORRECT:

$imagine = new Imagine();

/* set height to 800px (current 1200px) */
$file = $imagine->open($inputFile);
$size = $file->getSize();
$targetSize = new Box($size->getWidth(), $size->getHeight());
$file->resize($targetSize->heighten(800))->save($tempOutputFile);

/* get the resized image 533x800px*/
$createdFile = $imagine->open($tempOutputFile);

Temp image temp_outpur.jpgis no 533x800px - color is STILL CORRECT:

/* we need 667x800px so i want to apply white pixels to right and the left

/* drawing a new image with the needed pixels */
$newBox = new Box(667, 800);
$emptyImage = $imagine->create($newBox);

$size = $emptyImage->getSize();
$wSize = $createdFile->getSize();

/* calculate the center x-point */
$x = ($size->getWidth() / 2) - ($wSize->getWidth() / 2);
$center = new Point($x, 0);

/* paste the temp_output.jpg onto the created file */
$emptyImage->paste($createdFile, $center);
$emptyImage->save($outputFile);

The result output.jpg 667x800px - color is INCORRECT:

Here is a Side-by-Side diff (output.jpg is a little bit gray....):

anybody?

I tried with imagick and gd.
I also skipped the temporary save within this to lines to save image quality:

$file->resize($targetSize->heighten(800))->save($tempOutputFile);
$createdFile = $imagine->open($tempOutputFile);

But neither things worked for me. Please help!

Got the same problem. Image is grayed out a little.

we have also this behavior when image are downsized (landscape highres pictures)
@romainneutron any idea ? merci !

I had the similar problem when after image resizing colors become a little bit "zombie". And I've used this code for resizing:

use Imagine\Imagick\Imagine;
use Imagine\Image\Box;

$imagine = new Imagine();

// $file contains path to the file
$image = $imagine->open($file)
    ->thumbnail(new Box(1500, 980))
    ->save($outputFileName, ['jpeg_quality' => 90]);

Solution for me was comment the line with image stripping:

...
$thumbnail->usePalette($this->palette());
//$thumbnail->strip(); <-- comment this line
...

in method \Imagine\Image\AbstractImage::thumbnail.

Image weight become more but the quality is good.

I've encountered the same problem.
Cause of this problem is, that color profile is removed in strip().

This modification of \Imagine\Image\AbstractImage::thumbnail() copies color profile from original image to thumbnail:

...
$thumbnail->strip();
$thumbnail->profile($this->palette()->profile());
...
