Editing
The built-in Text Editor (see section 12.4.19 (page 154)) automatically understands
the .colours file format, but an external text editor can also be used. To edit the
.colours file using Rockbox, “play” it in the File Browser. The file will open in the
Text Editor. Upon selecting a line, the following choices will appear:
Extension
Colour
If Extension is selected, the virtual keyboard (see section 4.1.3 (page 26)) appears,
allowing the file extension to be modified. If Colour is selected, the colour selector screen
appears. Choose the desired colour, then save the .colours file using the standard Text
Editor controls.
13.1.5. Loading Backdrops
Rockbox supports showing an image as a backdrop in the File Browser and the menus.
The backdrop image must be a .bmp file of the exact same dimensions as the display
in your player (160×128×16 with the last number giving the colour depth in bits). To
use an image as a backdrop browse to it in the File Browser and open the Context
Menu (see section 4.1.2 (page 24)) on it and select the option Set As Backdrop. If
you want rockbox to remember your backdrop the next time you start your player the
backdrop must be placed in the /.rockbox/backdrops directory.
13.1.6. UI Viewport
By default, the UI is drawn on the whole screen. This can be changed so that the UI is
confined to a specific area of the screen, by use of a UI viewport. This is done by adding
the following line to the .cfg file for a theme:
ui viewport: X,Y,[width],[height],[font],[fgcolour],[bgcolour]
Only the first two parameters have to be specified, the others can be omitted using
‘-’ as a placeholder. The syntax is very similar to WPS viewports (see section 13.2.2
(page 160)). Briefly:
• ‘fgcolour’ and ‘bgcolour’ are 6-digit RGB888 colours, e.g. FF00FF.
• ‘font’ is a number: 0 is the built-in system font, 1 is the user-selected font.
Example
ui viewport: 15,20,100,150,-,-,-
This displays the menu starting at 15px from the left of the screen and 20px from the top
of the screen. It is 100px wide and 150px high. The font and the foreground/background
colours are defined in the theme .cfg file or in the Theme Settings menu.
