* Quota display
|
|
*
|
|
* Modify the following few elements to change the display of the image.
|
|
* Modifiable attributes are:
|
|
* bool border :: Defines whether you want to show a border around it?
|
|
* bool unknown :: Leave default; Defines whether quota is "unknown"
|
|
*
|
|
* int height :: Defines height of the image
|
|
* int width :: Defines width of the image
|
|
* int font :: Changes the font size & font used in the GD library.
|
|
* Available values are from 1 to 5.
|
|
* int padding :: Changes the offset (in pixels) from the top of the image
|
|
* to where the top of the text will be aligned. User
|
|
* greater than 0 to ensure text is off the border.
|
|
* array limit :: Holds the integer values of in an associative array as
|
|
* to what defines the upper and lower levels for quota
|
|
* display.
|
|
* High - Quota is nearing capacity.
|
|
* Mid - Quota is around the middle
|
|
* Low - Currently not used.
|
|
* array color :: An associative array of strings of comma separated
|
|
* values (R,G,B) for use in color creation. Define the
|
|
* RGB values you'd like to use. A list of colors (and
|
|
* their RGB values) can be found here:
