odcmlookupaci?
odcmlookupaci?
hello,
i have a few questions regarding unix and dwgdirect library:
1.
i use odcmlookupaci, to get color index out of rgb color.
on win32 platform, all works ok, but when i tried to compile it on hp-ux platform, i found out, that odcmlookupaci is not defined on unix platform.
how can i convert rgb to index color on unix platform?
2.
are the headers for windows platform the same as the one for unix platform? i did one quick check and it seems like that they are the same header files. so if this is true, i assume that i can use only one set of header files for both productions (win and unix).
3.
while compiling on unix platform i get following messages:
warning 749: "../../dwgdirect/include/odarray.h", line 692 # the cast from 'odgepoint2d *const' to 'odarray<odgepoint2d,odmemoryallocator<odgepoint2d > >::buffer *' is performed as a
'reinterpret_cast'. this operation is non-portable and potentially unsafe.
return (const buffer*)(((buffer*)m_pdata) - 1);
warning 749: "../../dwgdirect/include/odarray.h", line 191 # the cast from 'const odarray<odgepoint3d,odmemoryallocator<odgepoint3d> >::buffer *' to 'odgepoint3d *' is performed as

return (((buffer*)m_pdata) - 1);
i am using acc hp ansi c++ b3910b a.03.37

hi tomaz,
1. we will get odcmlookupaci implemented for non-windows platforms in the next update.
2. the headers are the same for windows, unix, and mac, except for the eoln characters used in them.
3. hp acc is probably the noisiest compiler we use, with respect to warnings, future errors, etc. we test on all of our released platforms, and hp hasn't given us any problems so far--but we do intend to go through and fix this type of thing to reduce the number of warnings produced (on all platforms).
