Summary0003318: png scaling: resize used instead of resample
Descriptionmanufacturer logos are often of a very delicate structure, with fine lines and strong contrasts.

when such a logo is resized, the result is often very ugly.

php's gd lib has also methods to resample images, which brings much better results.
Additional Informationattached see the different results of resizing and resampling

resize is only used when GD lib version 1 is installed. As of now this should only rarely still be the case
This has been the case since the first public release in github 9 years ago...
