International support and hyphenation

The command \usepackage[utf8]{inputenc} enable writing regularly.

The command \usepackage[brazil]{babel} enables (brazillian) hyphenation (hifenização).

To teach latex the hyphenation of specific words, \hyphenation{ exem-plo pro-ble-ma}.

The above commands are often associated with \usepackage[T1]{fontenc}, but this do not appear to be mandatory.

PDF Version

To generate PDF files with version 1.4:

dvipdfmx -V 4 test.dvi
ps2pdf -dCompatibility=1.4 test.ps

The problem with this method is that the structure of chapters do not is generated for navigation within the file.

Compact PDF

To decrease PDF file size. I test and it can really deacrese the file size. But the efficiency depends on the file contents:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

# /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
# /default selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.
# /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
# /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
#  There is a bug with the 'printer' option
# /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.

gs -sDEVICE=pdfwrite -dColorConversionStrategy=/Gray -dProcessColorModel=/DeviceGray -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf

Other possibility is to convert PDF to PS, and then PS to PDF.

Captions

The default \caption provides two arguments. The first is optional and defines what is set in the List of Tables (LoT), while the latter is mandatory and is used in the setting of the actual caption. If you don't supply the former, it's passed as equivalent to the latter.

\caption[<LoT entry>]{<regular caption>}

Tips

• Online: go sans serif.
• Verdana = Microsoft
• Lucida Grande = Mac OS
• Georgia = formal
• AVOID Times New Roman!
