Method Detail

isCssLinearGradientValue

public static boolean isCssLinearGradientValue(String cssValue)

Checks whether the provided value is a linear gradient or repeating linear gradient function. This method does not check the validity of arguments list.

Parameters:

cssValue - the value to check

Returns:

true if the provided argument is the linear gradient or repeating linear gradient function (even if the arguments list is invalid)

parseCssLinearGradient

public static StrategyBasedLinearGradientBuilder parseCssLinearGradient(String cssGradientValue,
                                                                        float emValue,
                                                                        float remValue)

Parses the provided linear gradient or repeating linear gradient function

Parameters:

cssGradientValue - the value to parse

emValue - the current element's em value

remValue - the current element's rem value

Returns:

the StrategyBasedLinearGradientBuilder constructed from the parsed linear gradient or null if the argument value is not a linear gradient or repeating linear gradient function

Throws:

StyledXMLParserException - if the provided argument is a linear gradient or repeating linear gradient function, but the arguments list is invalid
