This logo was designed for a now-defunct MeetUp group.
All the GIFs on this page were generated from one PostScript
file, webcentric1.eps, which is
viewable here as text.
A GIF image is created from the file using ImageMagick's
convert
utility.
The command I used for all of them, changing only the filename
for the resulting GIF, is:
convert webcentric1.eps xxx.gif
This creates a GIF file 336 x 336 pixels.
Different sizes can be generated
using convert
's -resize
command, but
better results are obtained by changing the scaling in the
PostScript file.
(It can be edited in any text editor.)
For example, to cut the dimensions in half, change
the BoundingBox
comment at the top of the file
to:
%%BoundingBox: 0 0 168 168
...and add a scale
instruction on a line
after %%EndProlog
:
.5 dup scale
The webcentric1.eps
file in
an emacs
text editor window.
The file is rendered in a gv
window that
automatically updates the display when a change is saved.
Modifying the logo
The file is mostly a prolog which defines various values and procedures. The different logos displayed on this page were made by adding instructions after the end of the prolog. The examples below are all accompanied by the code necessary to create them.
I have put together a file of colours in PostScript format:
rgb.ps, (here as
text). Any lines can be copied from this file into
webcentric1.eps
, and the names used to replace the colours in
the examples below.
The file, webcentric.ps (plain text) from which I created the logos I originally submitted, was thrown together on the spur of the moment and is rather convoluted.
