【转帖】valid Bit Depth For Rasterized Layouts
 
valid bit depth for rasterized layouts...
valid bit depth for rasterized layouts...
obviously, because autocad uses 256 color palettes, it makes most sense for an output bitmap to be 8-bit. however, is it valid to have anything else? 24-bit obviously since it will just expand the pixels to rgb values instead of index values, but about color reduction to 1-bit? btw, i haven't had a valid image come out with that depth, so i don't think it is possible, but...
my question is, what is possible\suggested? some documentation of each device's capabilities would be a great addition to this toolkit...
