strValue

String representing the numerical value to set: the multimedia engine will manage converting the string into the corresponding numerical value.

The value is formatted with the following rules:

•	Color values are formatted like "#RRGGBB" where:

- "#" represents the control character used for formatting colors in HTML code: the presence of this character is mandatory

- RR represents the hexadecimal value of the color's red component

- GG represents the hexadecimal value of the color's green component

- BB represents the hexadecimal value of the color's blue component

For example the green color will be represented with the value "#00FF00"

•	Boolean values are rendered as

- "1" or "True" for indicating the boolean "true"

- "0" or "False" for indicating the boolean "false"

Return value

Value	Meaning
