public Paint()

Method Detail

isOpaque

public abstract boolean isOpaque()

Gets whether this Paint is completely opaque. An opaque paint is one that has no alpha component in any of its colors. It may be possible for a Paint to be opaque and yet return false, if it cannot be easily determined whether the paint is actually opaque. For example, the ImagePattern may not be able to cheaply determine its opacity.

Returns:

true if the Paint is opaque, false if it is not opaque or if it cannot be determined.

valueOf

public static Paint valueOf(java.lang.String value)

Creates a paint value from a string representation. Recognizes strings representing Color, RadialGradient or LinearGradient. String specifying LinearGradient must begin with linear-gradient keyword and string specifying RadialGradient must begin with radial-gradient.

Parameters:

value - the string to convert

Returns:

a Color, RadialGradient or LinearGradient object holding the value represented by the string argument.

Throws:

java.lang.NullPointerException - if value is null

java.lang.IllegalArgumentException - if value cannot be parsed
