Philip,
With the recent upgrade to 3.7 I saw improved bitmap import
capability. Good enough I can finally put the company logo on
the drawing. *smiles*
It looked good so I created a new library object that included
the bitmap image and used the object in a drawing. I made
sure I saved the technology page as well as the drawing.
Next time I started xcircuit, it blinked on the screen,
disappeared, and the xterm reported "segmentation fault".
I poked around and determined if I removed the line in the
.lps file for the bitmap, xcircuit would run. And xcircuit has
no problem loading the drawing with the bitmap. I tried changing
the path to the bitmap to an absolute path - still didn't
work.
So it seems the bitmap can only exist in the "user" library
associated with a particular drawing. If the same object is
added to a "system" technology page, xcircuit won't start.
Bug?
Definitely.
Limitation?
Clearly.
Or user error? *smiles*
Not at all.
I have been using corporate logo graphics for some time now in drawings.
Had I ever saved those to a library, I would have immediately seen this
error. Graphic image data were not being saved along with .lps files,
only with the standard .ps files, and calls to graphic elements for
which the data were not loaded would cause an immediate crash. I have
corrected both errors. The fixed distribution is in "git", and the
tarball will be regenerated tonight.
Complicated effects can be realized with a "clipmask", which is also
a new feature of XCircuit. I create a gradient color field with the
"gradient" command (which only works on the command line, as yet),
then draw a clipmask over it to get the MultiGiG company logo (file
attached---this will probably get stripped off in the email list
distribution).
Regards,
Tim
