![]() All by using simple brushstrokes to retouch just the areas you want. Magically remove unwanted objects, clone parts of your photos, lighten or darken precise areas, and do much more. Many of the most important adjustments can be applied automatically, using a machine learning algorithm trained on 20 million photos. In Pixelmator Pro, you’ll find everything from essential color adjustments like brightness, contrast, and exposure to advanced tools like multi-channel curves and wheel-based color balance. Edit the colors in your photos in any way you want.And with full support for RAW photos, a collection of stunning adjustment presets, and incredible retouching tools, it couldn’t be easier to turn good-looking photos spectacular. The collection of powerful, nondestructive color adjustments in Pixelmator Pro lets you edit the colors in your photos, or even videos, in any way you want. However, all the scenarios with bad performance are using the same version of ImageMagick: 6.9.10-23.Powerful tools for perfecting your photos. Similarly, the Imagick version does not seem to affect it. The PHP version does not seem to affect the issue, since versions 7.1 and 7.2 do or do not have the performance problem in different scenarios. I did some more research, and created the following table (data from php -i): Source So now I have no clue where the cause of the problem is, since we’re seeing the same problem but with different versions here… Interestingly, the problem is not present here in PHP 7.0 and 7.2, but it starts appearing from PHP 7.3 (and in PHP 7.4). This yielded the following results: Ubuntu 16.04 / PHP 7.0: ~2s RUN apt-get update & DEBIAN_FRONTEND=noninteractive apt-get install -y php php-imagick I tried several PHP versions in Ubuntu/Debian using the following Dockerfile (using ubuntu:16.04, ubuntu:18.04, ubuntu:20.04, and debian:10 as ): ![]() Or with using Debian/Ubuntu packages over the compiled php that the image uses? No - on the same EC2 instance, various PHP versions perform great outside of Docker: Unless something radical changed between those PHP versions, which magnifies the Docker issue…ĭo you get the same experience outside of Docker? It would be weird if that was the case here, since there’s such a huge difference between PHP 7.0 and later versions with this issue (while they share the same Docker host). #493 is similar, or the If I understand correctly, it’s not exactly the same: #493 is about a performance problem with PHP 7.0 in Docker, while this problem does not occur with PHP 7.0, but only with later versions.Īlso, that other issue seems to be caused by some Docker image/volume characteristics. All versions showed similar (good) performance, indicating that the problem is not related to the PHP version itself, but rather something in the Docker image.Īlso, I tried a Dockerfile without using install-php-extensions from mlocati/php-extension-installer, by installing ImageMagick manually in the Dockerfile: I also ran the test script on the same instance without Docker (using PHP from sudo yum -y install php70-cli php70-common php70-pecl-imagick) for PHP 7.0, 7.1, and 7.2. It is clear that starting from PHP 7.1, something is wrong with the performance of the \Imagick::resizeImage() operation, since it’s approximately 10 times slower than in PHP 7.0. I obtained the following output/results: PHP 7.0: ~2s with substituted by some valid version):ĬOPY -from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/įinally, I ran the test script from above using docker run -it imgbench php imgbench.php.Īll the files used for this test, can be found here: imgbench.zip. ![]() ![]() Then, I built the following Dockerfile (using docker build -t imgbench. ![]() I created a new AWS EC2 t3.medium instance with the Amazon Linux AMI and installed Docker using sudo yum install docker. $image_blob = $image-> getImageBlob() bench(" blob") $image-> setInterlaceScheme( Imagick:: INTERLACE_JPEG) bench(" interlace") $image-> setImageCompressionQuality( $image_quality) bench(" compress") $image-> resizeImage( $image_size, $image_size, Imagick:: FILTER_LANCZOS, 1, true) bench(" resize") ![]()
