entities color definition at rendering time
entities color definition at rendering time
hi all,
is there the possibility to specify entity color when an entity is rendered ?
i'll try to explain my problem:
i load a dwg file and want all the entities in the dwg to be rendered using colors defined by me and not using the default color mapping. for example, all the entities with color index 1 (red) must be displayed with odcolorref(0,128,0) etc...
is there any possibility to obtain this result, apart from cycling all the entities and modifying by hand their color properties ? i there any callback that the renderer engine calls immediately before rendering an entity that i can override to obtain this result ?
thank you to everyone!!

it seems that the most effective way in your case is substituting your own palette instead of default one.

hi sergey, thanks again for your answer.
i undestand your suggestion, but i don't have any idea on how to implement it :-( .
do you have an example, or some documentation/function to search for ??
thanks again,
carlo.
odgsdevice::setlogicalpalette()
see odamfcapp sample dwgviewer.cpp
m_pdevice->setlogicalpalette(..)
