JPEG is an algorithm for storing image data in files. It uses compression methods to reduce the size of the files that store the images.

The JPEG algorithm takes a percentage parameter that specifies the compression level that is applied to reduce the resulting file size at the expense of sacrificing the fidelity of the compressed image relatively to the original image.

The package can compare the original versions of an image and another version after being compressed using the JPEG algorithm with a given compression level.

The result is an image that shows the differences between the original image and the compressed version, so you can see the the fidelity level that is lost.

Read this article to learn more details about how this notable PHP package works.


 



The package PHP Image Compression Analysis is one of the few PHP packages that was considered notable recently because it does something that is worth paying attention.

The basic purpose is: Compare an image with itself encoded as JPEG

Here follows in more detail what it does:

This package can compare an image with itself encoded as JPEG.

The main class takes the path of one image file and creates a new image in JPEG format using a given compression level.

The class can scans the original image and the newly JPEG encoded version and creates a third image that highlights the difference between the initial image and the recompressed version.

It also takes a scale parameter that defines the level of amplification of the differences between the two images.

Notable PHP packages can be often considered innovative. If this package is also innovative, it can be nominated to the PHP Innovation Award and the author may win prizes and recognition for sharing innovative packages.

If you also developed your own notable or innovative packages consider sharing them, so you can also earn more visibility for your package.
