Unfortunately there is no user mailinglist. According to the wiki, questions can be asked here....

Here is my question

I need to reduce the byte size of a color scan.

Up to now I think the following steps should be made:

- sharpen to reduce noise
- scale to ~120dpi
- reduce colors

Doing these steps one after the other wouldn't be the best result. To get the best result, I need a tool which can make these steps in one optimized algorithm.

Up to now we use convert (imagemagick) and net-ppm tools. But I want to switch to a library. I think VIPS would be a good choice.

The scans are invoices, not photos.

Any hints appreciated.
