Each logo is a graphic (scene) that is more or less complex for each object (images, animations, updatable texts, crawls), and this type of graphic is controllable with the appropriate commands.
One or more scenes are inserted into a project. Such commands at a low level can be sent using the pass-through commands and .ctm files with the custom effect of the driver. With the Fixed, Variable and Crawl effects, you can only manage relatively simple graphics, which work as follows:
•By default, the driver takes it for granted that the user has inserted the logos in a project called Etere.
•By default, the logo number corresponds to a scene in the project identified by the logo number
•By default, the Fixed effect does not manage animations.
•By default, the Variable and Crawl effects update in sequence fields that must be called a,b,c,...,z (max 26 fields)
The default behaviour can be modified by inserting an appropriate OradCGCustom.ini file in the executable directory. This type of file must contain a section for each logo that one intends to use; each section is of the type:
n: logo number
p: (Project) project name (if the line is absent, Etere is used by default)
s: (Scene) scene name (if the line is absent, n is used)
a: (Animation) animation names to start, separated by spaces (if the line is absent, no animation starts)
e: (Exports) names of the updatable fields separated by spaces (if the line is absent, a,b,...z are used)
In the OradCGCustom.ini file, below are some examples of the tests with the graphics provided by Orad. In particular:
•logo 1 recalls a fixed logo (colour bars)
•logo 2 recalls a logo with 2 animations
•logo 3 recalls a logo with 3 updatable fields
•logo 4 recalls a logo with various crawls, 2 fields of which are updatable
In the excluded part below, with the semi-colons, are 3 commands coded in hex for use with pass-through commands.
