Source files
Once movies, still pictures and sounds are added to the yellow albums, they
become album files. All the information pertaining to album files is linked to their
thumbnails.
Album files
Source files refer to the media stored on your computer. As opposed to album files
or thumbnails, they can be considered the 'original' data files.
Trimming
This task refers to getting rid of unnecessary portions of an object.
Transition
The point at which one movie scene ends and another one begins is called a
transition.
Templates
Upon installing ImageMixer, you will have a number of pre-designed pictures which
you may like to use as backgrounds for your own layouts. These are called
templates, and they may be accessed by clicking the [Templates] button.
Templates can neither be changed in size, nor edited.
Custom templates
ImageMixer lets you save your own designs for use as backgrounds in future
layouts. They may be accessed by clicking the [Custom Templates] button.
Object
Figures, images, and text arranged in layouts are called objects.
Control point
Once an object in a particular layout is selected, the four corners surrounding the
object are displayed as control points. They can be dragged to change the size the
object.
Control points are displayed slightly differently in Windows and Macintosh.
