PureBasic Forums - English

Hello,

I see lot off topic about alpha, but no ask why don't add this function
to works with 32bit image
Color = RGBA(Red, Green, Blue, Alpha)
Result= Alpha(Color)

support for 32bit image with Color= Point(x, y) and Plot(x, y,color)

Best regards and excuse me for my bad english

The alpha could be tagged onto the end of the existing function - 0 being default?

Code: Select all

x=RGB(r,g,b[,a])

Well, 255 as default sound better

I thought that 0 was "not transparent"?

Just as 0,0,0 means no colour, 255,255,255 means all colours

Think of it like a percentage, except it ranges upto 255 rather than 100.

ahh, I thought that zero was a special case for compatibility?

0 means it's transparent, and 255 means it's opaque

ic, so for existing PureBasic compatibility it should default to 0, but ideally it should be 255 (RGB($ff,$ff,$ff) currently generates $00ffffff, not $ffffffff).
