• Number g: The green value of the pixel (0-255).
• Number b: The blue value of the pixel (0-255).
• Number a: The alpha (opacity) value of the pixel. If greater then 1, it will be normalized to a value between 0 and 1. Defaults to 1.

Return

• PixelClass The PixelClass instance.

intensity()

Calculates the pixel intensity.

Return

• Number The pixel intensity (0-255).

toHex()

converts the input color to a hexadecimal string, this removes opacity

toRGBAString()

converts the input color to a RGBA string.

:sparkling_heart: Support my projects

I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).

However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:

• Starring and sharing the projects you like :rocket:

• —I love books! I will remember you after years if you buy me one. :grin: :book:

• —You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea:

• —Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).

• Bitcoin—You can send me bitcoins at this address (or scanning the code below): 1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6

  

Thanks! :heart:
