PNG output compression

[paulofloresjunior]

Hi!
I'm testing this solution and I able to change compression using quality parameter for webp and jpg, but it does not work for PNG.
There is chance to change the png compression output in this image handler?

Thanks!

@paulofloresjunior filters:quality(NUMBER) filter should work for PNG as well, for example, https://MY_CF_ID.cloudfront.net/filters:quality(50)/panda.png
Please refer to the output below for different quality calls

Size Name
1.9M panda.png    <-- no filter
481k panda_10.png <-- filters:quality(10)
561k panda_50.png <-- filters:quality(50)

Hi @fisenkodv thanks for your reply, did you make any adjustment to make it work?
For me it does not work anyway.
Try theses links below, return same file...

@paulofloresjunior I didn't make any adjustment to make it work. Do you use the latest v6.0.0 version?

[paulofloresjunior]

@fisenkodv Sure, I used the automated deployment about 1 month ago. I just check here in Lambda and it says "Serverless Image Handler (v6.0.0): Performs image edits and manipulations"
Are you sure that files you are you receiving after transformation still are png files?

[fisenkodv]

They should be, since I didn't apply an additional filter. Would you mind to raise an issue and attach the PNG file?
