Intelligent Building Series C-Touch Programming Reference

8.2 File Structure

Ultimately, the C-Touch Configuration Software generates a file which is

downloaded to a C-Touch unit. The format of the images downloaded for each

component depend upon the type of component. Each component requires

between zero and three images to be downloaded to the C-Touch unit so that it

can draw the components when needed:

No Image

Completely invisible components (such as a shape with no border and

background or a button with no border, background, text or image) do not

require that an image be downloaded. This means that they use very little

memory. These components are often used to create invisible “hot spots” on the

screen area. These hot spots are used to cause a page change when pressed.

Single Image

Shapes and text require a single image.

Two Images

Buttons generally incorporate two images, one for the active state, and one for

the inactive state. One of the two images will be drawn by C-Touch according to

the state of the associated C-Bus Group Address. If the Active and Inactive

Images are the same, only one is downloaded.

Three Images

Sliders have up to three images. Two are for the background of the slider

(active and inactive) and the third is for the thumb (the part that slides up and

down).

Dynamic Text Components

Clocks, Percent Indicators and Monitors all have their text generated

dynamically (ie. as required). These components have a single image saved for

their background, and have fonts downloaded as required. The fonts used for

Text components do not need to be downloaded, as they are saved as an

image.

NOTE: Care needs to be used when using components which

are translucent (i.e. transparent, but not invisible). For

example, a button with no border or background, but which

does have an image or text. When the image for this is saved,

it is a copy of what is on the computer screen, but it is not

actually transparent. This means that a component below the

image will be hidden from view.
