Xreader: horizontal scroll lock

[fugata]

Feature request:
An option to left the horizontal scrolling of a pdf.

Explanation:
To maximize screen real estate, in Xreader I zoom in to the document so that there is almost no left/right margin on the screen. That works well until I need to jump to a different page using either the < > button on the top, or entering the explicit page number under "Select Page" (also on the top). When I do either one of these actions, the new page now appears with the original full left margin and I have to manualy h-scroll it back. It would be great to the have an option to lock the h-scrolling so the output stays the same regardless of how we scroll up/down.

Note:
(1) I work mostly with pdf generated by latex, and this issue of h-scrolling jumping around does not arise when I click on a in-text reference --- e.g. a numbered equation; the jumping around occurs only when I use < > or entering a page number.

(2) Some pdf reader has the extra feature of "cropping" the margin; that becomes handy e.g. for manuscripts where the left/right margin changes depending on whether the page number is odd or even. My request here is a lot simpler: Just lock the h-position for all pages.

Many thanks for your consideration!

Question, do you get PDF files from others or do you create PDF files yourself?

Since PDF pages are jpg images, you could batch process:

1. extract all pages (as jpg)
2. cut the superfluous margin of extracted pages
3. re-assemble all pages to a PDF
4. Ocr pages

Other solutions:

• Maybe there's some app able to crop margins directly, but I don't know such an app.
• Even simpler, you could extract PDF content as txt file and use some markdown editor to study your PDF.

Of course if you never print PDF files and you only read them, it would be a better solution to hide PDF margins as you describe in point 2, usually such features are found in mobile phones apps.

Anyway, you've my vote
