How to use the seminar class with pdflatex
How to avoid pstricks with seminar-class
----------------------------------------
The pstricks package triggered by \usepackage{semcolor} and
\usepackage[dvips]{pstcol} uses ghostscript and cannot be
used with pdflatex.
Use of pdflatex has the following benifits:
- picture can be included pdf jpg png - formats (no eps)
- output is directly in pdf (no dvips)
- these features save lots of disc space
and improves the quality of pictures
N.B.: PostScript was made for vector graphics not for
bitmaps.
The following steps are needed to get the functionality of
semcolor etc. again:
- convert pictures to png adding a lightgrey background:
convert a5.eps -pen gray90 -opaque white a5_fc.png
The script: eps2png.sh does this for all eps files in a
directory
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Replace complete latex preample (
Between \documentclass and \begin{document})
by
\input garsem.tex
garsem.tex works with both:
normal latex: in this case the pstricks.sty and .eps
files are used
and pdflatex: psshadowboxes are simulated by a
combination of colorbox + fancybox
pictures should be .jpg .pdf or .png
This provides colored boxes with shading:
headbox, figbox, tabbox, gdbox, dsbox
dont use psshadowbox etc. directly !!
Selection of colors can be done in 2 ways:
change to users default:
\renewcommand{\headboxcolor}{blue} % default yellow
etc.
for each box individually by an optional argument:
\eqbox[red]{\frac{3}{2}} % default yellow
^ ^
N.b. brackets not braces
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Replace:
\epsfig{file=figs/a7.eps,width=36mm}
by:
\includegraphics[width=36mm]{figs/a7}
Replace:
\psshadowbox[fillstyle=solid,fillcolor=yellow]{
by:
the above mentioned boxes: \eqbox etc.
Bits and pieces:
---------------
Figures included with "\includegraphics" come out bigger compared
to the \epsfig.. (~20 %)
-> reduce width
\coloredshadowbox are bigger
-> increase \hspace
