Example
This example will set current AutoCAD color scheme to black on white then loads a DXF file
L_INT SetAutoCADFilesColorSchemeExample(L_TCHAR * pszDXFFileName, pBITMAPHANDLE LeadBitmap) { L_INT nRet; L_UINT32 dwFlags; /* If the current AutoCAD color scheme is not black on white, change it */ nRet = L_GetAutoCADFilesColorScheme(&dwFlags); if(nRet != SUCCESS) return nRet; if(dwFlags != AUTOCADFILES_COLORSCHEME_BLACKONWHITE) { nRet = L_SetAutoCADFilesColorScheme(AUTOCADFILES_COLORSCHEME_BLACKONWHITE); if(nRet != SUCCESS) return nRet; } /* Load the DXF file */ if(LeadBitmap->Flags.Allocated) L_FreeBitmap(LeadBitmap); nRet = L_LoadBitmap(pszDXFFileName, LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); if(nRet != SUCCESS) return nRet; return SUCCESS; }
