We looking at very simple button design:
1) Border color is on/white/2px
2) background is set to clear (no color assignment and no icon)

4) Button name/label white
Now... I realize that if # 2 above is true, then possibly, since
there are no pixels at all in the background that the algorithm might
not be possible from a video card point of view... so we *could* set
the background to white and set the opacity to a
grayscale?transparency value of say... 50% but the idea is that the
text of the button name/label remains fully, 100% opaque, even
thought background has an alpha channel value (some level of
transparency)
From my fiddling... (I could be missing something) this is not
possible either with buttons of fields or graphics.
The use case is, again, as discussed in another thread: we want
visibility of the text on top of *any* image to be visible. We do
this in print all the time... but we cannot separate the blending of
the text label or text itself and the background of a button/field in
LC... at least I have not found a way.
Um, well, at the risk of annoying you somewhat . . .
I have almost always "rolled my own" buttons just because of the
limitations on Livecode-native
buttons.
I use GIMP with a series of layers (nothing particularly original or
difficult there): one for the
'button' (rectangle with rounded edges), one for the image, and one
for the label. Then one can
fiddle around with levels of transparency as much as one likes.

Oh, I'm sorry, I fired that one off a bit too quickly.
The faux buttons made in GIMP have to be imported and used as images in
Livecode, because PNG
images with differing levels of transparency seem to lose the
transparency when they are used
as icons inwith actual buttons.

Would be grateful if you could clarify this.
