Alignment sets the position of an image or
video file when it appears on a mobile device. Alignment can be
important for an image or video file that does not fill the addressable
screen size.
Open the Emulator tab by doing one of the following:
From Adobe Device Central,
select File > Open, navigate to an image file, and double-click
the file.
In Photoshop or Illustrator, open a file. Select
Save for Web and Devices and click Device Central.
In Adobe Premiere Pro or After Effects, open a file.
Select File > Export > Adobe Media Encoder.
Select H.264 from the Format drop-down menu, check Open in Device
Central, and click OK.
On the Adobe Device Central Emulator tab,
expand the Alignment panel.
Click a horizontal and a vertical alignment button.
Note: Scaling and alignment changes are saved until a device
is reloaded. Whenever you reload a device (by double-clicking it),
the device returns to the default alignment and scaling settings
defined in the profile.
