thumbnail. If you set this option to Never, you have to press the Thumbnail button in
theFile Open Dialog to be able to see a thumbnail of your image.
"File> Save" Saves the Image
This is by default set to “Always” but if you save your image on a networked disk ( NFS,
SMB etc.), saves are sometimes slow and saving isn’t always that necessary. Instead
you will only save when the file is really changed.
12.8 Session Management
12.8.1 Window Positions
Session management is a way to restore the GIMP session that was running prior
to quitting the GIMP. I.e. simply quit GIMP and start GIMP again. GIMP will now
along with the Window Manager try to restore the GIMP session you that was running
before you left GIMP. You can disable or enable this feature with the Always Try to
Restore Session checkbox. GIMP can save its window positions – where, for example,
theGradient Selection dialog is displayed on your display. If you use the Save Window
Position on Exit option then GIMP will save the positions of open dialogs. It can be
useful to arrange your GIMP desktop with this option enabled and then restart GIMP
and disable the option. You will thereby have a consistent desktop each time you start
GIMP.
12.8.2 Devices
If you have a graphics tablet and use it with The GIMP, you will have several devices
that you can preconfigure in theDevice Status dialog. However, if you use the Save
Device Status on Exit option, the preconfiguration will be overwritten and the last state
before exit will be the new configuration.
12.9 Monitor Settings
12.9.1 Get Monitor Resolution
If you create anew image with the size of two by two inches and don’t have right-click
View Dot for dot enabled, then you should be able to the measure the image directly
on the screen to a size of two by two inches.
If the size you read is wrong then you have to adjust your monitor resolution in this
dialog.
The GIMP is using a manual setting by default (72dpix72dpi). If you run GIMP on
a Unix workstation then you can probably use the “From windowing system” option and
get a correct value. If you run on PC hardware you will most likely not be able to use
the value given by the windowing system. You have to measure and set those values
by hand which can be a bit bulky. There are two fields – one with the default measure
unit DPI and one with custom measure unit which can be useful for those who are used
to the metric system.
