[Feature Request]: Add "Keep source file Page Size" to Ajust Page Scale

[nachokb]

Feature Description

The adjust page-scale command requires the user to specify a Page Size. There needs to be a way to leave the page as is but scale its content.

Why is this feature valuable?

I happened to need a way to just scale down the content a bit while leaving the page intact without the need to know anything about it previously.

This idea met a good reception in the project's Discord.

Suggested Implementation

Add an option "Keep source file Page Size" to the pageSize attribute;

ScalePagesController needs to be aware of this option, and treat it accordingly;

This will need a first step to read the dimensions and use those as targetSize;

Additional Information

Other implementations:

• pdfScale: supports this use case;
• could not find another one;

(pdftk and others do not support scaling content)

No Duplicate of the Feature

• I have verified that there are no existing features requests similar to my request.
