Add hexadecimal value to Colour

PaulS

Problem

Having a colour stored in a hexadecimal way is much easier than storing 3 or 4 values for the same colour.

Proposed Solution

Add Hex to Colour

Example Workflow

Var red As Colour = Colour.Hex(FF0000)
Var redalpha As Colour = Colour.Hex(FF000088)

or maybe

Var red As Colour = "#FF0000"
Var redalpha As Colour = "#FF000088"

or ...

PaulS I like the second one, I have a pop up screen to set window background colour in a user table and having them in one field as string is much better

This has now been implemented for the next release.

Colour now has two new methods:

Colour.FromHex(hex As String) As Colour
Colour.ToHex() As String

The accepted hex formats are CSS-style strings:

Var red As Colour = Colour.FromHex("#FF0000")
Var redAlpha As Colour = Colour.FromHex("#FF000088")

#RRGGBB creates an opaque colour. #RRGGBBAA includes alpha, with the alpha value last. Hex digits are case-insensitive, so #ff0000 is also valid.

ToHex() returns uppercase text:

Print(Colour.Red.ToHex())                    # #FF0000
Print(Colour.RGBA(255, 0, 0, 128).ToHex())   # #FF000080

I chose an explicit Colour.FromHex(...) method rather than allowing direct assignment from a String to a Colour, so ObjoBasic keeps its normal static type checking clear and predictable.

Thanks for the suggestion.
