High!
Meanwhile, I finally found out how to display object patterns produced
from bitmaps vectorized with Inkscape correctly... but then, I found
that either the lowest layer (a simple three-column flag gradient
pattern) is darkened completely or significantly brightened (see
attached image).
Here is the current version of my AfghanFlag() macro:
// beginning of code
#macro Flags_AfghanFlag()
Flags_ThreeColumnFlag(0, <0.74509805, 0, 0>, <0, 0.6, 0>) // Layered
texture, coat of arms object-patterned texture yet to be added!

// end of code
Inkscape generated 8 vectorized layers from the original coat-of-arms
bitmap; originally, I just used finish { Flags_Finish } as defined
further up in flags.inc. As in flags.pov, the flag object is called with
the newly introduced "lights" parameter set to 0, the ambient value in
Flags_Finish is 1.
The original color values for the three-column pattern are (in 8-bit
notation):
<0, 0, 0>
<191, 0, 0>
<153, 0, 0>
But when I add the first layer with object pattern, the colors beneath
darken significantly:
<0, 0, 0>
<125, 0, 0>
<51, 0, 0>
- although the color for all parts outside the bezier spline is set to
rgbft 1 and also the finish of the object pattern texture layer is
ambient 1! From the second layer on, the red and green beneath is even
reduced to a total black! How is this possible?
On the other hand, when I instead divide the ambient value by a value
higher than 1.7 (and, in turn, multiply color triple of the inner parts
of the object pattern with the same value), the colors of the flag are
brightened to:
<0, 0, 0>,
<255, 0, 0>,
<0, 255, 0>
Why?
See you in Khyberspace!
