Print PDF: link, or no link?

[sean-fitzpatrick]

A design question for @APEXCalculus .

When producing the PDF version (via LaTeX), there are a couple of options in the publisher file to be aware of:

latex @print can have values yes or no. print="yes" indicates that the PDF is intended to be printed, while print="no" indicates that we want an electronic PDF. The main difference is that in the electronic version, cross references are hyperlinked, and the text is usually a different colour to indicate the presence of a link.

There is also asymptote @links. When set to yes, Asymptote images are clickable, with the link taking us to an interactive HTML version of the figure.

But <latex print="yes"/> overrides <asymptote links="yes"/>

The sea of PDF outputs is as follows. First, there are 4 versions of the book that we currently produce. (We could add a 5th if you want to resurrect the "calculus with quarters" version.)

• Original APEX
• APEX, but with videos
• APEX for the U of L standard calculus sequence (4 semesters)
• APEX for the U of L accelerated calculus sequence (3 semesters)

Of these, you probably only care about the first.

But each of these versions has 3 different types of PDF:

• Electronic PDF: in colour, single-sided, links active.
• Print PDF: black and white, two-sided, no links.
• Colour print PDF: in colour, double-sided, no links

The TL;DR question is about this last version: I've set the print option to "yes", and this overrides the fact that I also set the asymptote images to link to the web versions.
Do we want to keep this as a print-only (but in colour), or would you rather it be a 2-sided version of the electronic PDF?

In PR #431, you linked a color version of the text, 2-sided, links active. (At least, I think the links are active; hyperlinks across the text work, but the asymptote links don't seem to.) How does that fit into the 3-version paradigm you gave above?

If I'm understanding things right, my initial thought is I'd like the electronic version to exactly mimic the print version, except have color and hyperlinks (both within text and to interactive asymptote graphics). Is there an advantage to having the Electronic PDF be single-sided (I'm assuming that means that even/odd pages all look the same, vs. odds having a large margin at left, etc.).

[sean-fitzpatrick]

Interesting. I didn't expect hyperlinks to work. Or perhaps they are just styled to be the same font/colour in the print version.

I'll dig in a bit. One other difference that's supposed to happen is that the print version has page references (since there's no hyperlink, you get something like "Example 4.2.11 (page 183)").

But I've overridden that feature because the added text changes where pages break.

Right now I think the only difference between "print" and "color-print" is that the former is black and white.

I think the idea with single-sided layout is that if you're scrolling on your laptop, you'd rather have not have the text jumping back and forth.

I'll make the 2-sided colour version have links, I think.

I've set it so that all hyperlinks are active.
