The ordering here tends to reflect the bytes. So argb puts
the alpha byte first in the array whereas rgba puts red first.
But there's other ways here including just saying argb(...)
or foo.as!"argb" or whatever well.
I think about .rgba.
Yes. The ordering! The logic.
ARGB = .argb
Thanks!
0x00AABBCC.argb
0x00AABBCC - is ARGB value
.argb - is unit
...in my logic.
120.px
120 - is Pixel value
.px - is unit
...in my logic.
100.percent
100 - is Percent value
.percent - is unit
...in my logic.

Thanks!
This concept:
class X
{
this()
{
props.fontFace = "Ubuntu Mono";
props.fontSize = 24.px;
props.lineHeight = 15.px;
props.color = 0xFF;
props.backColor = 0x22;
// or
props.color = 0xFF.rgb;
props.backColor = 0x22.rgb;
// or
props.color = 0x88FF.argb;
props.backColor = 0x8822.argb;
}
}
Thanks!

Hex constant method starts from ".a": 0xCCCCCC.argb
We have:
static import winapi=core.sys.windows.windows;
struct Color
{
union
{
winapi.COLORREF native;
struct
{
ubyte r;
ubyte g;
ubyte b;
}
}
ubyte a = 0xFF;
}
Color argb( uint color )
{
Color c;
c.native =
cast( uint ) (
( ( color & 0x00FF ) << 16 ) |
( ( color & 0xFF00 ) ) |
( ( color & 0x00FF ) >> 16 )
);
c.a = ( color & 0xFF00 ) >> 24;
return c;
}
Goal:
auto color = 0x00AABBCC.argb;
Has error:
Error: exponent required for hex float
( at 0x00AABBCC.argb )
What is it ?
How to implement beauty code like the: #CC.rgb ?
