Summary	0003318: png scaling: resize used instead of resample
Description	manufacturer 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.

Sven Brunk 2022-01-28 10:36 administrator ~0013531	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...
