Hi everyone.
I would like some help on this script I currently have if anyone is able to.
What the script does - Exports multiple layers into single PNG images. Script is made with combination of scripts I've found over the net, and Actions I've composed.
What my problem is - PNG images are exported in low quality.
Basically, every image exported via this script is working fine, however the quality that it is exported into is much lower than that as you would export it manually via "File Export."
Can you help me with -the scripting code needed to implement so that the export quality is the same as you would do it manually?
Thank you for taking the time on this, I really appreciate any help and feed back.

Resource - An extract of the code used to export is just below. This is the last part of my script and as I've said, I don't own this particular part it is something I found over the web.
