Alpha component?

[jolleekin]

Hi Michael,

Is there any plan to add the alpha component?

Thanks.

Also, any plan for

1. operations such as *, +, -, lerp (linear interpolation)
2. inverted getter

Alpha is planned, but far down the road. Still not sure if that should be new classes or an optional parameter on the existing classes.

Operators for +, -, and averaging are also planned. I have to add a few more color spaces first so that all of these operations make sense though.

I'm not sure what you mean by "inverted getter." Can you describe in more detail?

The inverted of (r, g, b) is (255 - r, 255 - g, 255 - b).

I think new classes with the alpha component makes more sense as someone may be already using your package. In the future, you may deprecate classes without the alpha component.

In addition, since the package is mostly used in web applications, please consider

• Adding a new method or modifying toString to return the HTML color string ('#123', 'rgb(0, 0, 0)', ...)
• Adding a static parse method or a new constructor, which takes a string and returns a color, to each class
• HexColor's default constructor should support '#ddd' and '#ddeeff' formats rather than 'ddeeff' format

Well, a lot of this issue is still on the todo list, but I have added a toCssString() method to RGB, hex, and HSL color spaces, so you can use the Color package to generate css strings a little easier now.

I got here when I tried generate a transparent color to my background. I din't find a way to generate a transparent CSS color patter using Color library.
