Screen definitions is a part of the DISE NoBorders technology. The definitions describe the relationship between the DISE Movie and the screen(s) that it is going to be displayed on. If you only have one screen, the screen definition is simply the resolution of the DISE Movie / screen, but things get more interesting if the DISE movie is going to be displayed over several screens at the same time. In that case, a screen definition will describe the total resolution of all the screens combined, as well as the placement of each individual screen on that big canvas.
To setup screen definitions, go to File > Options > Preferences > Default values. Then in the window appearing, click on Edit screen setups... to bring up the Setup screen definitions window.
DISE Composer comes with a number of standard resolutions already defined. These are all one-screen definitions. When you select a different definitions in the list, you will see a small icon at the right in the window, illustrating the definition. Add a new definition by pressing the New button to the right, or edit an existing one by selecting it in the list and pressing the Edit button. The Delete button will delete the selected definition.
Start by clicking on the New button to create a new screen definition.
- Screen definition name
- Horizontal resolution / Vertical resolution
- Prevent "maximize to screen" for this resolution
- Save movies created with this setup in another directory
- Screen name
Measurements in pixels on the DISE movie canvas.
- Width / Height
Width and height of the screens visible area on the disemovie canvas. This is usually the resolution of the screen.
Here, we will create a screen definition where the three screens are horizontally placed.
- Bring up the Setup screen definitions window as specified above.
- Enter 3 Screen Example as name.
- Leave the Resolution fields empty for now, we will return to it later.
- Now, we want the three screens in a row, each having a resolution of 1280x720. In addition, they should be 5 cm apart.
- Click Add to add the first screen.
- Enter "Example Screen 1" as name for this screen.
- Enter 1280 under Width and 720 under Height. We want the screen to start at the top left of the canvas, so we leave the X and Y at 0.
- Click Ok.
- Next screen up next, click Add again and enter the the name "Example Screen 2".
- Between this screen and the first we want a 5 cm gap. Let’s say the screens have a PPI of 96. Now we just have to calculate how many pixels 5 cm represent: floor(96 * (5 / 2.54)) = 189.
- This screen will have its X position at 1280 + 189 = 1469 and Y 0. The width and height is the same as the first.
- The third screen, "Example Screen 3", will start at X = 2 * (1280 + 189) = 2938.
- The width and height is the same as the first.
- Return to the Edit screen definition window after defining all three screens by clicking OK. We now know what the total resolution will be: Under Horizontal resolution enter 4218 (2938 + 1280) and under Vertical resolution enter 720.
- Click Ok to create the screen definition. The dialog will then take you back to the Setup screen definitions window.
- To use this screen definition, go ahead and select it in the list that is presented and click on OK.
- From now on you can also use this screen definition by going to File > New (movie) and then selecting the 3 Screen Example screen definition.
- When selected you will be presented with the following view:
