HSLA color values are an extension of HSL color values with an alpha channel – which specifies the opacity of the object. The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

Does Java have referential transparency?

A function is called referential transparent if it always return the same result value when called with the same argument value. For referential transparency, we need our function to be pure and immutable. Example : The method `String.

Are the color components premultiplied by the alpha component in Java?

When constructing a Color with an explicit alpha or getting the color/alpha components of a Color, the color components are never premultiplied by the alpha component. The default color space for the Java 2D ™ API is sRGB, a proposed standard RGB color space.

How do I get the alpha value of a color?

Specifically, first you convert your color coordinates to RGB space: where alpha is an integer between 0 (fully transparent) and 255 (fully opaque), inclusive. This value you can pass to the Color constructor, making sure to give true for the second argument. Thanks, but what is rgba |= alpha << 24? I just realized I misread the documentation.

What is the alpha value of an opaque color?

An alpha value of 1.0 or 255 means that the color is completely opaque and an alpha value of 0 or 0.0 means that the color is completely transparent. When constructing a Color with an explicit alpha or getting the color/alpha components of a Color, the color components are never premultiplied by the alpha component.

How to make RGB opacity in Java?

The easiest way is to specify R, G, B, and A directly, using this constructor: public Color (float r, float g, float b, float a). I know you have HSB, but you can convert to RGB easily enough. I know this is old, but all I do when I want opacity made with the Java built-in Graphics Object, is new Color (RRR, GGG, BBB, AAA).
