« Return to previous page

Option name:
back_image_mode
Default value:
"auto"
Added in version:
2.1
Data type:
string [?]

The datatypes used in this documentation for specifying SVGGraph options are described below. All options can be a literal value of the data type described, a variable containing the data type, or an expression that will produce the data type when evaluated (and they must always be valid PHP expressions).

array
An array(), the number and data types of its members will depend on the option for which is it used.
boolean
A boolean TRUE or FALSE value, or any values that convert easily such as 1, "1", 0 and "".
callback
A callable function, which can be either the name of a function or an anonymous function itself.
colour
Any of the colour values supported by SVG inside a single or double quoted string. These include three and six digit hex codes, RGB and RGBA colours, and colour names. SVG uses "none" for no colour, which generally leaves things transparent.
fill
A colour value or one of the gradients and patterns supported by SVGGraph. See the SVGGraph colours page for details.
integer
A negative or positive whole number or 0.
number
Any number supported by PHP, for example 1 or -3.2 or 1.63e5 or M_PI.
string
Single or double quoted strings. Remember to double-quote your strings if you are inserting a line break: "Line 1\nLine 2".

global background image

Background image display method.

The available options are:

  • auto

    The image will be uniformly scaled to fit inside a virtual box, the width and height of which will be given by the back_image_width and back_image_height options.

  • tile

    The image will be uniformly scaled and tiled in blocks using the back_image_width and back_image_height options for dimensions.

  • stretch

    The image will be stretched to fill the back_image_width and back_image_height dimensions.

See the SVGGraph background image page for details and examples.
