Configuring Strabo Screens

Strabo is based on the display of two screens to create the stereo image: the screen at the back is the left image; the screen on the top the right image. The link between the top/back screen and the right/left image is defined in the stereo.ini file (“…/Program Files/Orbit GIS/Orbit GIS/users/name/strabo_stereo.ini”).

This stereo.ini file looks like:

Setup=
 Name=Strabo
 Screen=
  Id=L
  DeviceId=\Display2
  Index=0
  FlipX=false
  FlipY=false
 Screen=
  Id=R
  DeviceId=\Display1
  Index=0
  FlipX=true
  FlipY=false

The values for the DeviceId's in this file should be set correctly for each screen. Looking at the orbitgis.log file, you can see which screens are connected to your PC:

148:t3418: [DisplaySetups] : Retrieved graphics configuration.
149:t3418: [DisplaySetups] : Getting screen devices
150:t3418: [DisplaySetups] : Screen device 0 : '\Display0', (1280x1024), 32bits, 60Hz
151:t3418: [DisplaySetups] :   > Type : RASTER_SCREEN
152:t3418: [DisplaySetups] :   > Full-screen ? true
153:t3418: [DisplaySetups] :   > Display-change ? false
154:t3418: [DisplaySetups] :   > Bounds : java.awt.Rectangle[x=0,y=0,width=1280,height=1024]
155:t3418: [DisplaySetups] : Screen device 1 : '\Display1', (1280x1024), 32bits, 60Hz
156:t3418: [DisplaySetups] :   > Type : RASTER_SCREEN
157:t3418: [DisplaySetups] :   > Full-screen ? true
158:t3418: [DisplaySetups] :   > Display-change ? false
159:t3418: [DisplaySetups] :   > Bounds : java.awt.Rectangle[x=1280,y=0,width=1280,height=1024]
160:t3418: [DisplaySetups] : Screen device 2 : '\Display2', (1280x1024), 32bits, 60Hz
161:t3418: [DisplaySetups] :   > Type : RASTER_SCREEN
162:t3418: [DisplaySetups] :   > Full-screen ? true
163:t3418: [DisplaySetups] :   > Display-change ? false
164:t3418: [DisplaySetups] :   > Bounds : java.awt.Rectangle[x=2560,y=0,width=1280,height=1024]

In this example we can observe three screens called \Display0, \Display1 and \Display2. It is up to you to decide which display will be defined as the back screen, and which display is for the upper screen. As you can see above, the resolution values of the different screens are shown in the orbitgis.log file. If these values differ, it is rather easy to point out the Strabo screens. In the above-mentioned stereo.ini file you can set up your displays. By running Strabo Softcopy you can see if the images are correctly placed on the Strabo screens. If this is not correct, you need to replace the two display values again in the stereo.ini file.
