Nothing is incorrect - it's just a limitation of the Paint Window..
The .image you extracted from the #text member has an alpha channel.
The alpha channel is what contains the anti-alias'd 'cookie-cutter'
outline that we call text.
It's proper incorporation is what causes the stage display & cast
thumbnail to show the expected result.
The Paint Window, however, can only display & edit the merged RGB
info, & not RGB+Alpha. So it can't show the alpha of a bitmap if it
contains one.
It displays as a rect = member().rect in the #text member's foreColor.
Similarily, if you go to the PI's member tab & turn OFF the 'Use
Embedded Alpha', then the stage display will match the paint window's
display.
You might like to try:
alpha = new(#bitmap)
alpha.image = member("Text").image.extractAlpha()
This will pull out that alpha channel & put it into another new member.
You'll note that it's an 8 bit gray scale member.
