For exemple if i use Function FloodFill(MyBrush, 50, 50, #NOCOLOR, #RED, 128) <= 128 is transparency value (0 at 255)

see result in picture (side right) :

Code: Select all

- New: FloodFill() now accepts an optional "AlphaChannel" table tag; if this is set to TRUE, FloodFill()
  will operate on the brush's alpha channel instead of on its color channels; when used in alpha channel
  mode, values in the range of 0 to 255 must be passed instead of RGB colors

Does this help?

Code: Select all

@DISPLAY {Color = #WHITE}

CreateBrush(1, 640, 480, #RED, {AlphaChannel = True})
SelectAlphaChannel(1)
Circle(#CENTER, #CENTER, 200)
EndSelect
FloodFill(1, 200, 200, #NOCOLOR, 128, {AlphaChannel = True})
DisplayBrush(1, #CENTER, #CENTER)
WaitLeftMouse
End

Alpha channel isn't available in 8 bit graphics modes.
I'm on registered MorphOS using FlowStudio.

Oops, looks like this is a bug but it occurs only on some systems, e.g. it works correctly on Windows. However, you can easily work around it by just passing -1 instead of #NOCOLOR to FloodFill().
