This yields:
As you can see there are several optimization problems I am facing:
- The chapter style may not be properly defined.
- The vertical line beside the chapter numbering is not properly aligned with the horizontal bar above it.
- The chapter names like L'Hopitals Rule are not properly vertically centered with the vertical bar. This can be obvious in the third image.
- There is a vertical displacement of where the text starts after the chapter name which is clearly obvious in the third image.
- The geometry of the page is not properly defined. I just want a regular lettersize paper with about the same output as the image shows.
Things I am considering defining for this template are:
- To be able to place the horizontal bar in every page that belongs to the chapter. Possibly a vertical bar to the right on odd pages starting at
current page.north eastand going down possible an inch. - To be able to define different colors for every chapter.
- To be able to place different images and different pages by using a macro possibly in the preamble. Something like:
\pagepic{<pagenum>}{pic}. This needs to be positioned as shown. Note the images will use the space indicated in the demo. One pic per page.
Any suggestions will be highly appreciated. I am doing this just for leisure. Just trying to learn new tricks and optimization techniques.
2.85\marginparsep,-1.125in, etc. Could you add more comments to explain where these come from? (If they're just invented by trial-and-error it's no surprise that the various objects don't quite line up!)-2.85\marginparsepis just a forced dimension that I used to make it seem to be aligned.-1.125inis just a particular height from the top most of the page. It has no special significance.
