|
|
Hello,
Just kicked the tires on gschem, to see if I should switch. Since it
doesn>t look like there will ever be a Windows version I am running it
in VirtualBox on an XP machine. Looks pretty good so far. Anyhow, a
question:
People like me must include schematic excerpts in documents a lot. When
I use the "Write image" export utility it does produce a file I could
then import but the resolution isn>t adequate for a decent quality
document. At large width and height settings it>s actually so chopped up
that parts values cannot be deciphered anymore. In Eagle I could set a
resolution instead of width and height and when set to 300 that produces
a pristine PNG image.
Is that possible in gschem somehow? Or if not are there any plans to
improve the "Write image" routine? Alternatively, is there a trick to
store the whole sheet in a somewhat popular format (preferably not PDF,
PS or EPS) and then use another graphics program to pick out the wanted
piece?

# Postscript printing of the schematic is supported
# PNG image writing of the schematic is supported
I would try to create a .PS or .PNG-file, import it into IrfanView
and save it from there in a format I could work on with.

Well, that>s what I tried, image writing to PNG. The result was rather
ugly and at some write sizes plain not readable. EPS was refused by
IrfanView with something like "file contains errors".

There _are_ currently Windows versions out there running.

Each Windoze user has to *compile* executables for himself.
As that weeds out a lot of the folks who have low software skills,
it minimizes the occurances of Clueless Windoze User Syndrome.

there will always need to be

are **native** Windoze-compatible executables.

So, how is the speed with your level of horsepower? |

A quick check of their website leads to this question... Do you have
ghostscript installed? IrfanView "supports" eps by having ghostscript
convert it to a raster, which will make it ugly again.
What I recommend is exporting EPS and converting it to PDF, then use
acroread to view/print it.
Or I use ghostscript convert the EPS to an anti-aliased PNG, which
results in better quality than gschem>s default PNG exporter. |

Well, I don>t need to read/print but folks like me must often include
snippets and complete pages of schematics in Word documents, usually as
figures with captions. Mostly to explain circuitry to folks who won>t
understand it by just looking at the schematic.

Some friends in a German NG convinced me to give Linux a shot and
coached me a bit through the maze of VirtualBox and Ubuntu, then gschem.
So I poked around a bit after evince didn>t work and, tada, found that
Gimp (which comes with the distro as default) does the job nicely. So
it>ll go like this:
gschem write image to EPS format. EPS into Gimp (takes a while), set to
300dpi, cut unwanted areas, store as PNG file. Import PNG file into Word
document. A bit cumbersome but that produces an acceptable quality,
quite comparable to Eagle schematic exports :-)
I don>t know squat about programming but if you guys ever think of
improving this export feature maybe a lot of the work can be reduced by
using code parts from Gimp so that gschem can do a straight write as a
300dpi (or even selectable resolution) PNG file.

That pretty much excludes me as well. I am most certainly not a
programmer but know CAD quite well.

Well, it>s so so. It>s ok but not quite as snappy as Cadsoft Eagle. But
Eagle doesn>t have a hierarchical sheet structures so what can ya do?
Right now Ubuntu forgets the links to the LAN server every time I power
it down. Hopefully I>ll figure that out one of these days but it>s only
a minute to re-install that in the morning.
