Okay, so I'm currently writing a report (in the article class) which has a section full of chemical spectra. I figured that two spectra per page is a good number, so I write

RequirePackage{calc}

newlength{halfpage}

setlength{halfpage}{textheight/2}

newcommand{twoandabitperpage}{height=halfpage}

newcommandmygraphicspage[2]{centeringexpandafterincludegraphicsexpandafter[#1]{#2}}

This means that I can say mygraphicspage[twoandabitperpage]{spectrum_1.pdg} and mygraphicspage[twoandabitperpage]{spectrum_2.pdg}, and this will give me a nice couple of spectra on one page. (Note that I need the expandafters or else my code will break. I don't fully understand it, but it's there and I guess it works).

''Great!'' I thought to myself. In practice: not great. My spectra section is as follows:

part{Spectras!}

section{Spectrum One}

mygraphicspage[twoandabitperpage]{spectrum_1.pdf}

section{Spectrum Two}

mygraphicspage[twoandabitperpage]{spectrum_2.pdf}

Therefore, taking half of the page and making it my image height does not always work when there are sections and parts at play (for their titles make up more than is ideal of the page).

And so I went to Google: I found this

newlengthremainder

newcommandmeasurepage{dimexprpagegoal-pagetotal-baselineskiprelax}

remainder=measurepagerelaxtheremainder

So to my understanding (and I may be wrong, as I don't understand TeX very well [I couldn't figure out how to make the mygraphicspage command...]), what this does is it measures the rest of the page, probably through some black magic—after, of course, defining that the remaining length of the page shall be called the remainder. Then, it prints it? It that what that last line is for?

Anywho, I want to able to define

newlength{almosthalfpage}

setlength{almosthalfpage}{textheight-remainder/2}

Where remainder is defined by the page in question. This page will be specified when and only when I use the length almosthalfpage.

For example, say that my textheight=40em, and my part title makes up 4em, and I have two section titles making up 2 em each. Then, the remainder of my page is 32em. Therefore, my individual image heights should be 16em. This remainder of 32em is defined by remainder, but only when I specify the image height (which is a function of remainder) for that particular page.

I am really sorry if this makes no sense at all... Any help would be appreciated! And to a lesser degree of importance, I would appreciate anyone commenting on better ways to convey the code I currently have (i.e., should I be using def instead of newcommand, and let? How do I use those commands? etc. etc. ...).

Thank you!
