 Description   

Setting of quality property is not working for PNG files. It is working correctly with JPG files, but not with PNG.

PNG files are lossless by design - there is no 'quality' which could be adjusted. It is possible to decrease file size by reducing the number of colors in the image (the color depth) from PNG-24 to PNG-8, for example, but the whole point of PNG is it produces lossless images, so there is simply no quality value as in JPEG.

Hello,

This ticket is now marked as closed due to one of the following reasons:

  • A long period of inactivity
  • Uses an old or Beta version of an application, module, or framework that we no longer support
  • The issue is no longer reproducible or has been fixed in later versions

If you are still facing a problem or consider this issue still relevant, please feel free to re-open the ticket and we will reach out to you.

 

Thank you,

The Magnolia Team
