[GFX][gdlib_png]  and  [GFX][png_truecolor]  are both not mentioned in my 
localconf.php and thus are =0. So my GMENU is rendered with GIFs.
Trying to set format=png does not change the output format (as Christopher 
also tells in his posting) - the images are still rendered as GIFs and the 
flipped transparency effect is also still there.
If I additionally set [GFX][gdlib_png]=1 then I do get PNGs, but WITHOUT any 
transparency at all (also observed by Christopher if I understand him 
right).
['GFX']['png_truecolor'] seems to have no effect on the problem(s).

Here is a screendump that shows the effect with GIFs ([GFX][gdlib_png]=0):
http://www.digilog.de/T3-4b3-GIFBUILDER_problem.gif

The TS that rendered this screendump consists of two GIFBUILDER objects that 
are identical to yours. The second differs only in that it has the backColor 
reduced to be numerically less than the fontColor:

page.100 = COA
page.100  {
    10 = IMAGE
    10.file = GIFBUILDER
    10.file {
        XY = 200,200
        format = png
        quality = 95
        backColor = #d3d9db
        transparentBackground = 1
        10 = TEXT
        10.text = Hello World
        10.fontColor = #d3d9da
        10.fontSize = 40
        10.offset = 20,100
        10.niceText = 1
        10.fontFile = fileadmin/fonts/ARIALN.TTF
    }
    20 = IMAGE
    20.file = GIFBUILDER
    20.file {
        XY = 200,200
        format = png
        quality = 95
        backColor = #d3d9d8
        transparentBackground = 1
        10 = TEXT
        10.text = Hello World
        10.fontColor = #d3d9da
        10.fontSize = 40
        10.offset = 20,100
        10.niceText = 1
        10.fontFile = fileadmin/fonts/ARIALN.TTF
    }
}


The problem ist completely reproducable on my installation.
My server configuration for these tests is:
WinXP SP2, Apache2.0.48, PHP4.4.0, GraphicsMagick 1.1.6-Q8

Anything else you want me to test?

I don't know if it's related, but in b3 nothing I do will allow me to
produce an image with BOTH OF .niceText = 1 AND .transparentBackground
= 1, UNLESS gdlib_png is set in the install tool. Also, simply adding
'format = png' to a gifbuilder object does NOT cause it to create a
png UNLESS gdlib_png is set in the install tool.

Have I misunderstood what your changes have made available (i.e. I
thought we could now swittch between gif/png/jpg in gifbuilder
objects...)?
