Automation Protocol Filename-Based Commands

Filename-Based Commands

The following commands are provided to allow access to images stored on

the Oxtel Series products. These products support alphanumeric filenames

(including the file extension) of up to 39 characters.

Generally speaking the file-systems on Oxtel Series products are case

insensitive. However this is not the case for Imagestore HD-TV, Imagestore

300, and Intuition products that utilise the EXT2 file-system. It is therefore

recommended that filenames are never duplicated with different cases, and

that automation commands that pass filenames do maintain case.

It is recommended that filename extensions be included within any

automation commands. This will to ensure that the correct file is always

utilised.

It is recommended that filenames contain only the characters A-Z, a-z, 0-9,

and underscore.

Load Image R0

This command loads an image, animation, Easytext file or clock onto the

specified layer. Unlike the 8 command, the image is loaded by name, rather

than by number. If the layer is currently faded up, the image will be seen to

wipe down the screen. The R0 command supersedes the command 8 (which

remains supported). If a non-existent filename is supplied as Param_2, the

current image will be removed and no new image will replace it.

The following file types are typically loaded via the R0 command

• Still images (.OXT)

• Animations / Bugclocks / Easytext (.OXA)

• Intuition Templates (.TEM) – Intuition only

• MPEG video clips (.CLP) – Imagestore 2 only

Within Imagestore Intuition, several different formats of MPEG video clips

can be included within a template, but not loaded directly into Intuition

layers.
