Preserve alpha channel

[skifreak]

I'm very happy to have found this script - It's making my negative scanning life much easier..

This is not an 'issue' but more of a feature request - would there be some way to preserve the alpha channel? I'm scanning with Vuescan and doing all of my dust & scratch removal beforehand, but it would be nice to be removing scratches from the inverted/negfix'd files.

A bit late to the party :-)
Here is a script which seems to preserve the alpa channel and applies dust removal:

聚会晚了一点：-)
这是一个似乎保留了alpa通道并进行除尘的脚本：https :

Thank you very much, but are there instructions for using this script?
