Hello Guys,

I am using POV3.7. I am trying to display a bitmap file with 1 bitdepth, so i
write the Command "Bits_per_color=1" in the "povray.ini". But it doesen't work,
and still shows the bitdepth = 24.

Does anybody known how can i solve this problem?

Any help would be greatly appreciated.

Thank you very much in advance.

best regards,

Di

POV-Ray is comparatively limited in the combinations of bit depth and 
file formats it supports. The Bits_per_color setting is primarily there 
to allow >8 bits per color channel, or reduce the number of different 
colors to obtain higher compression rates (e.g. for PNG files).

Also note that Bits_per_color sets the number of bits per color channel 
(per pixel), not the total bits per pixel, so even a setting of 1 could 
only give you an RGB 3-bit-per-pixel file, rather than the 
1-bit-per-pixel format you're probably aiming for.

You'll need an external image manipulation tool to convert to a true B/W 
bitmap.

Make that "to /choose/ >8 bits per color channel [provided the file 
format supports it]".
