pdf

A short post to describe my last LaTeX creation: a template file that allows to merge odd and even pages together, considering also the case of the reversed even pages. As usual there is a little edit area that make the process very fast, without requiring any knowledge of LaTeX and if you have a subscription in an online editor like Overleaf you can execute it in your internet browser.

It happens that you have to print for job or personal pleasure, one or more posters in a big format and like me you don't use famous commercial software and you aren't a professional illustrator. But how can the color palette of your document fit the request of the typography? This post tries to show a simple conversion of a PDF from RGB to CMYK, using ghostscript library and imagemagick in a handy bash script.

Every time I have to break iteratively a series of pages in a PDF document or just to crop the white pieces, I need to use different software and to find manually the coordinates of the sections to cut and then adjust my old LaTeX template. It is an extenuating procedure that requires the use of external software and some compilations to fix the cuts. So I have written a new template to overcome these issues, thanks to TikZ and Overleaf or a local TeX editor with live update.

I publish the template which I used for the presentation of my Thesis, it could still be useful for write any types of presentation. Latex and Beamer gave me the faculty to focus my main attention on contents, avoiding the definition of color scheme and style. Beside the PDF output works in each PC and projector.

I made some experiments about the embedding of interactive 3D objects into PDF documents with LaTeX, but the results don't satisfy me. The big problem is localized in U3D conversion of my 3D content, whereas the writing of TEX file and compiling with pdflatex, once I had loaded the movie15 package and read the instructions, is very easy and fast.

There are two main items to include 3D graphics in your PDF documents:

In this article I show you a concrete example on the use of my previous tutorials about PDF optimizations, in particular I have added a new pagination, toc and bookmarks. The used PDF is a very old technical dictionary (in English, Italian, French and German), but it is not in copyright and for some words is yet useful.

Generally to facilitate my translations I use the following sites:

I admit it: my ebook reader has many problem in loading some type of PDFs, though I had made various tricks to fix this problem, like my site can testify! In last days I have tried a new approach, the conversion to CBZ, a type of archive file for the purpose of sequential viewing of images especially comic books. And for now, it works!

Sometime people shares PDF documents too big in size, so they are hard to keep and to display, specially in old PCs and eBook readers. Generally these PDFs are formed by images with high resolutions that need reductions. It follows my solution to cut down their size using ImageMagick in two steps.

In the previous article I explain how to insert toc and/or bookmarks using LaTeX in a PDF document, omitting a very boring aspect: selection and writing of all parts that you want insert in these ones (avoiding errors when the items are very numerous!). In order to automate this procedure, I wrote a small bash script that converts the output made by JPDFBookmarks in a text file pasteable in LaTeX.
