how to create bitmap?
hello, all.
i'm trying to create bitmap in pdb->writefile(.., true) method and getting an error message:
"object of class odgirasterimage can't be cast to odrasterconvertpe."
have no idea what that means.
all static macros looks like in place:
cdialog::initinstance() {
..
odrx_init_static_module_map();
odinitialize(&svcs);
odrx_declare_static_module_entry_point(bitmapmodul e);
odrx_begin_static_module_map()
odrx_define_static_appmodule (dd_t("winbitmap.gs"), bitmapmodule)
odrx_end_static_module_map()
pgsmodule = odrxdynamiclinker()->loadmodule(dd_t("winbitmap.gs")); // return valid pointer
return pgsmodule->createbitmapdevice();// crashes here
without bitmap option file writes fine but no preview on file/open from acad.
i'm building app with statically linked ddwg220+msvc60+win2k
any help will be appreciated.
thank in advance.
life would be so much easier if we could just look at the source codefff">fff">

additional info. this problem could be because of my
misunderstanding for bitmap parameter.
is it dwg preview bmp image like in file/open acad' dialog box?
thanks!

one of writefile() parameters controls creating thumbnail preview in output dwg or dxf file.
you need include one more module into your application: rasterprocessor. see odwriteex sample.

thanks, sergey, it is working now!
what was missing:
code:
odrx_declare_static_module_entry_point(odrasterprocessingservicesimpl);
#pragma comment(lib, "dd_vc6md_rxrasterprocessor.lib")
...
odrx_begin_static_module_map()
odrx_define_static_application(dd_t("rasterprocessor"), odrasterprocessingservicesimpl)
