 Apple Mac OS X
With GhostScript version 8.5x the import of PostScript does not work any more.
version 8.56 and 8.57 are reported to create problems with Cenon, something has been changed in GhostScript...
As a quick solution you should install an earlier version of GhostScript (gs). Also, a parallel installation of an earlier version is possible, if it is copied into the directory /usr/local/bin/ [2007-06-09] Crash on Power-PC when importing PostScript and PDF.
Please Update to Cenon version 3.82 from December 29th. This will fix the issue. [2006-12-29] The PostScript and PDF-Import doesn't work, what can I do?
Cenon needs GhostScript (gs) installed in the directory '/usr/local/bin/gs' or '/usr/bin/gs'. If you have installed a ghostscript version to some other path, you have to link or copy the file 'gs' to the search path of Cenon. [2004-10-19] Lines are not visible in printings or the Preview.
Mac OS-X does not display lines with zero line width. You have to set a line width in the Cenon (Stroke) Inspector.
With Cenon 3.70 you can set a default line width in the preferences. [2005-08-16]
 Linux / GNUstep
When starting Cenon I get the following error:
NSRangeException: Index 0 is out of range 0 (in 'objectAtIndex:')
This sounds like your GNUstep libraries doesn't fit the Cenon binary.
As an example, GNUstep GUI 10.3 is not binary compatible to previous versions. A solution is to acquire the right version of the GNUstep Libraries. Another solution is to compile Cenon yourself against the installed GNUstep libraries.
[2006-11-18] When starting Cenon the following error message appears:
loading model file /usr/lib/GNUstep/.../Main.gmodel... recursion encountered handling uncaught exception
Check, if Cenon has been installed in the correct path (/usr/lib/GNUstep/...). Debian uses a different install directory.
If Cenon is installed correctly, then probably your GNUstep GUI library is not compiled the same way as Cenon (for example debug versus stripped). Especially the Model bundle, loading the interface files. It helps to recompile GNUstep GUI (make clean + make).
[2006-11-18] The RPM package manager shows failed dependencies for libgnustep-base.so.x.xx and libgnustep-gui.so.x.xx."
The GNUstep libraries have to be installed in /usr/GNUstep/System/Library/Libraries (Debian: /usr/lib/GNUstep...).
If this is the case, you can safely install Cenon without dependency check:
rpm -Uhv --nodeps Cenon*.rpm
[2006-08-14] When I run Cenon I get: "Cenon[#####] No fonts found!"
When using the Art backend of GNUstep you have to install extra fonts (nfont packages). You can find the basic fonts on the vhf server: gnustep-fonts-0.1.1-1.noarch.rpm
[2004-11-20] I am encountering an error when I try to run Cenon using the 'Art' backend. The application throws up an 'Uncaught exception'.
You are using an old version of the GNUstep libraries. There was a bug with the menu fonts in combination with the art backend.
A current snapshot version of the GNUstep libraries (February 2004 or later) should do it.

 OpenStep Tips
A double click on a file opens the file in the text editor and not in Cenon
Select the file in the File Viewer of the Workspace. Then go to the Tool Inspector (Pop Up Menu Tools) of the Workspace (not Cenon), and move the Cenon symbol to the left. Doing this you set Cenon as default application for the selected file type. After a check for disks, no disk symbol appears in the shelf of the File Viewer
Disks are not displayed when their file name is missing or not appropriate. You can find your Disk in the root directory (/). Transport of Cenon files to DOS disks
Before you can copy a Cenon file to a DOS disk, you have to truncate the file extension (.cenon) to 3 characters (.cen). To use the file you have to change back the extension to .cenon.
If possible, you should use Unix or Apple formatted disks to transport files.
The prefered way to transfer files is a LAN (Ethernet). Killing a process
If it happens that you have a process hanging around as a zombi, you can kill this process. Go to the process list of the Workspace using the menus 'Tools - Processes'. If you have to kill Cenon, you must kill the output process (controller) too.
Import
The imported DXF graphic is displayed in a wrong size
Go to the preferences of Cenon to change the unit of the DXF import. The DXF format has no defined unit, that's why you have to tell the importing program the unit of the file. The size of imported fonts is not correct
You can tell the exporting program to flatten all text to a path.
If you are using HPGL or DXF, the cause is that no font information is inside the file, so Cenon will use the default font. If you are using PostScript, it is possible that the desired font is not installed on your system. In the latter case you can install the font as Type 1 font. Graphics which are generated using Freehand contain intersecting lines
In Freehand don't use the output option Split Complex Paths. Otherwise Freehand splits large paths into several smaller paths to limit the complexity of generated PostScript files. I can't import HPGL files
The extension of HPGL files must be .hpgl, or .plt. The case (lower case) is important on Unix systems!
I can't import PostScript-Files generated with Corel Draw.
Go to the preferences of the EPS export of Corel Draw and disable the setting for the image header (?). If you have this option enabled Corel Draw will add garbage to the PostScipt file.
