"""Support file to show FreeCAD thumbnails on Free Desktop Environments (like GNOME or KDE)
|
|
|
|
Installation:
|
|
- This executable file should be on the PATH so it can be found
|
|
"$ sudo cp freecad-thumbnailer /usr/bin"
|
|
and must have execution rights
|
|
"$ sudo chmod +x /usr/bin/freecad-thumbnailer"
|
|
|
|
- If a FreeCAD project file doesn't include a thumbnail the file org.freecad.FreeCAD.png is used.
|
|
Thus, the file src/Gui/Icons/freecad-icon-48.png must be installed.
|
|
"$ sudo cp freecad-icon-48.png /usr/share/icons/hicolor/48x48/apps/org.freecad.FreeCAD.png"
|
|
|
|
- The application/x-extension-fcstd MIME type should be registered
|
|
Check that a corresponding /usr/share/mime/packages/freecad.xml file exists
|
|
Make sure the MIME database is up to date
|
|
"$ sudo update-mime-database /usr/share/mime"
|
|
|
|
- Register this thumbnailer
|
|
Adding a file /usr/share/thumbnailers/FreeCAD.thumbnailer with the following content:
|
|
|
|
[Thumbnailer Entry]
|
|
TryExec=freecad-thumbnailer
|
|
Exec=freecad-thumbnailer -s %s %i %o
|
|
MimeType=application/x-extension-fcstd;
|
|
|
|
HINT: Make sure that the symlink /usr/bin/python exists and points to the Python executable
|
|
|
|
NOTE: To make sure FreeCAD saves thumbnail information:
|
|
|
|
Edit -> Preferences... -> Document -> Save thumbnail into project when saving document
