• The Start LaTeX button converts the source text in the input field into a graphical representation.
• The DPI(Dots Per Inch) input field indicates the resolution that is used to calculate the graphic representation (valid range: 60-600 DPI).
• This checkbox UTF-8 sets the encoding of the LaTeX source file. UTF-8 vs. Latin-1
• The Reset button clears the entire input field
• Templates or examples can be copied into the input field via the Load button and the pull-down-menu.
• The selection list Format enables the specification of the output format. In addition to the various image formats a PDF document can be produced with pdfwrite.
