Hi, it seems that the system for uploading files to the file box of an entry
(now http://planetmath.org/encyclopedia/FresnelIntegrals.html)
does not function. I would like add the clothoid picture
http://www.wakkanet.fi/~pahio/A/A/clothoid.png
to the entry. Can anyone help?
Jussi

I downloaded and then uploaded, so it's in your file list now.

Jon

Jon,
I am very grateful to you for uploading the picture. You master the thing since you have uploaded so many your own diagrams. Thanks!
Jussi

Jon, I got the error
"line 84: LaTeX Error: Cannot determine size of graphic in clo"
when I added to the code of
http://planetmath.org/encyclopedia/FresnelIntegrals.html
the lines
\begin{center}
\includegraphics[scale=0.5]{clothoid.png}
\end{center}
and tried to preview. Is it so that the system does not accept the png graphics files?
Jussi

I tried both SVG and JPEG once and it didn't work. I can't recall if I ever tried PNG, but I know I finally settled on EPS for some reason. Do you have the option of exporting to EPS? If not I'll see if the graphics package I have can convert from PNG to EPS somehow, but in the morning, as it's late here now.

Jon, I know nothing about EPS (and PNG:).

My old StarOffice Drawing package did a conversion from PNG to EPS, but it looks like there was some loss of quality.

I scaled it to the default 100% as the 50% reduction looked kind of small.

Jon

Jon,
Thank you very much for the clothoid diagram in EPS! (Was the 50% reduction sharper?)
Regards,
Jussi

Hi Jon, you have succeeded to get the clothoid and also your pictures in sight! Thanks! My picture is quite coarse though, but it has been such already before, too.

Who me? I didn't do anything but constant complaining.

It's my specialty.

I've been trying to convert the PNG to EPS again on a newer machine, but haven't succeeded in getting a better quality image yet.

Jon

Dear Jon,
Now I saw that the same damned devil has broken another entry containing graphics (http://planetmath.org/encyclopedia/CurvatureOfNielsensSpiral.html)! It is evident that all such disasters are caused by the new server machine =o(
What should I do?
Jussi
