Do you have a link to the .hpg file in question on the site?  (I'm thinking
HPGL.)

Yes, a link to the actual file would be useful.

It surely is HPGL or HP-GL/2, a vector cad format. Many HP printers will
print it directly.

Here are a couple links to information, including some software that
will open the file.
http://en.wikipedia.org/wiki/HPGL
http://filext.com/file-extension/HPG
Paint Shop Pro seems to be one of the more common ones. I think CAD
programs usually will import it too.

I may have a program that will work, but I think not on this machine.

Hello Brooke,
Irfanview is in fact very powerful, but as can see in V4.0, it is  n o t  capable to
read HPGL-files - so it is not capable to convert into another format.
I know only Autocad able to read .hpg, but that does not look very comfortable.

If you have a way to print-out these plot pictures (I suppose they are) so one
could make a sharp hi-q picture with a modern 6 Mp camera and use the
jpg pictures in your page, is that a possibility for you?

Hi Scott:

I have uploaded the smallest one E1938_asdrawb.hpg at:
http://www.prc68.com/I/pdf/E1938_asdrawb.hpg
it's also linked on the E1938 web page under Theory of Operation.

I have Autocad 14, but it did not want to load a .hpg file.  Maybe I need a
plug-in?  Autocad can drive an HP pen plotter to create .hpg files, but don't
know about loading them.

Have Fun,

Brooke Clarke

What are you using to convert the file?

I used this free program:
http://hpgs.berlios.de/
and got it to create a png file, but I had to edit the hpgl and remove a
few commands that the program (and my available documentation) didn't
recognize.

HPGL is pretty simple--I'll bet it wouldn't be much work to write a
quick-n-dirty HPGL to PS converter.

After Steve's reply I reinstalled an old version of Corel Draw that I
had. The image in Corel seems the same as the png from the free program.

Here's a link to the resulting png from hpgs
ftp://ftp.sonic.net/pub/users/rexa/E1938A/E1938_asdrawb.png

Corel opened the hpg ok, but needed some work to get it on the page
size. As I mentioned, I did have to remove a little bit of the hpg file
to get it to work with the hpgs program.

Here are the first few lines of the hpg file

IN;
PW .1875,1;PW .1875,2;PW .1875,3;
PW .1875,4;PW .1875,5;
PW .375,6;PW .1875,7;PW .1875,8;
.Y.@4096;
2:.J.K.I90;
0;
17:.N50;
19:INIP-21184,-16612,21184,16612SC-5296,5296,-4153,4153IW-5296,-4153,364,4114SP1PA-684,1258PD;
...

I changed that to

IN;
PW .1875,1;PW .1875,2;PW .1875,3;
PW .1875,4;PW .1875,5;
PW .375,6;PW .1875,7;PW .1875,8;
INIP-21184,-16612,21184,16612SC-5296,5296,-4153,4153IW-5296,-4153,364,4114SP1PA-684,1258PD;
...

since the program and I both didn't know what the extra lines meant. I
cut them out in a text edtitor and saved the file for input to the hpgs
program. Then it worked ok. I had renamed this new file to test2.hpg and
then I used this command line for the program (in a DOS box)
hpgs -d png_rgp -o test2.png test2.hpg

The png version seems a bit more useful to me than pdf, as many graphics
programs will open the png and allow editing. Fewer programs are
available to manipulate pdf's.

The png is viewable and printable in Irfanview, but looks a little
better when I open it in Ulead Photoimpact, that I had here.

Hope that helps.

-Rex

I had one on my old DOS 5 computer. I may look for it later.

Hi:

Scott will convert the files and I'll post them when they arrive.
I've also added a Windows control program to the page.
You may need to force a reload to see the new items.

Have Fun,

I succeeded to read it with Corel PaintShopPro XI and then converted it to
PDF with PDF Creator. The PDF file is 113kB but zip down to 96kB. Let me kow
if you're interested, and where I can put it (I don't have a server
available here).
Have a nice day,

Hi brooke,

The Windows control program link did not work.  Can you explain, a little bit,
about  the program on your web page, besides here.

thanks

Hi Didier,
I just put the file on your server under the name E1938_asdrawb.pdf. I can
easily save it to other formats as well if anybody prefers.
Thanks for giving it a home...
