Class Paint

java.lang.Object
javafx.scene.paint.Paint
All Implemented Interfaces:
Interpolatable<Paint>
Direct Known Subclasses:
Color, ImagePattern, LinearGradient, RadialGradient
public abstract class Paint extends Object implements Interpolatable<Paint>
Base class for a color or gradients used to fill shapes and backgrounds when rendering the scene graph.

Linear interpolation is supported between the following heterogeneous paint combinations:

Heterogeneous paint interpolation converts the Color to a visually identical gradient paint, and then performs a linear interpolation between the two gradient paints. If heterogeneous paints cannot be interpolated as described, the paints are interpolated as discrete.

  • Method Details

    • 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.

      JavaFX 8.0

    • valueOf

      public static Paint valueOf(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:
      NullPointerException - if value is null
      IllegalArgumentException - if value cannot be parsed
