how to resize paper background?
how to resize paper background?
how to resize paper background to fit my drawing extends? now paper background is too small (see attachment paperbackground.jpg).
i try to use following code, but it does not work:
oddbobjectid id = m_pdd->createlayout(buffer, &idblock);
oddblayoutptr newdwglayout = id.safeopenobject(oddb::kforwrite);
makeoddbhandle(&drwlayout->getid());
// next line sets layout extends etc.
setlayoutdata(newdwglayout, drwlayout);
m_pdd->setcurrentlayout(odstring(buffer));
oddbplotsettingsvalidator* pmanager = this->plotsettingsvalidator();
pmanager->setusestandardscale(newdwglayout, true);
pmanager->setplottype(newdwglayout, oddbplotsettings::kextents);
pmanager->setstdscaletype(newdwglayout, oddbplotsettings::kscaletofit);

hi,
i need more information from you. could you prepare small code example with file creation? or reproduce situation in mfcapp ?

you can reproduce "problem" if you replace odwriteex-example dbfiller::filldatabase -method with following code:
code:
oddbsetdwgcodepage(*pdb, (odcodepageid)0x0c);

oddbhandle seed(oduint64(10));
pdb->getoddbobjectid(seed, true);
// viewports
oddbviewporttableptr pviewports = pdb->getviewporttableid().safeopenobject(oddb::kforwrite);

oddbsymboltableiteratorptr piter(pviewports->newiterator());
piter->start();
bool usedefault = !piter->done();
oddbviewporttablerecordptr pviewport;
if (usedefault)
{
pviewport = piter->getrecordid().safeopenobject(oddb::kforwrite);
}
else
{
pviewport = oddbviewporttablerecord::createobject();

i cannot reproduce problem with current toolkit sources. could you tell me your used toolkit version ?
i have added
code:
oddbplotsettingsvalidator* pmanager = pdb->appservices()->plotsettingsvalidator();
pmanager->setusestandardscale(newdwglayout, true);
pmanager->setplottype(newdwglayout, oddbplotsettings::kextents);
pmanager->setplotcentered(newdwglayout, true);
pmanager->setstdscaletype(newdwglayout, oddbplotsettings::kscaletofit);
before '// remove "default" layouts' comment
ps : pmanager->setplotcentered(newdwglayout, true); is usefull too.
our toolkit version is 2.1.0 (vc8).
now it抯 works. i have to put oddbplotsettingsvalidator calls after everything is added to layout (before i call oddbplotsettingsvalidator just after layout was created).
before:
code:
oddbobjectid id = m_pdd->createlayout(buffer, &idblock);
newdwglayout = id.safeopenobject(oddb::kforwrite);
makeoddbhandle(&drwlayout->getid());
setlayoutdata(newdwglayout, drwlayout);
m_pdd->setcurrentlayout(odstring(buffer));
oddbplotsettingsvalidator* pmanager = this->plotsettingsvalidator();
pmanager->setusestandardscale(newdwglayout, true);
pmanager->setplottype(newdwglayout, oddbplotsettings::kextents);
pmanager->setplotcentered(newdwglayout, true);
pmanager->setstdscaletype(newdwglayout, oddbplotsettings::kscaletofit);
.. add objects to layout block (idblock) ..
now:
code:
oddbobjectid id = m_pdd->createlayout(buffer, &idblock);
newdwglayout = id.safeopenobject(oddb::kforwrite);
makeoddbhandle(&drwlayout->getid());
setlayoutdata(newdwglayout, drwlayout);
m_pdd->setcurrentlayout(odstring(buffer));
.. add objects to layout block (idblock) ..
oddbplotsettingsvalidator* pmanager = this->plotsettingsvalidator();
pmanager->setusestandardscale(newdwglayout, true);
pmanager->setplottype(newdwglayout, oddbplotsettings::kextents);
pmanager->setplotcentered(newdwglayout, true);
pmanager->setstdscaletype(newdwglayout, oddbplotsettings::kscaletofit);
thanks.
yes, i see. validator cannot calculate extents if there are no objects in the layout.
now there is another problem. oddbplotsettingsvalidator calls do not work (or there are not any visible differences, see dll_toolkit.jpg) if i build our application by using dll-version of toolkit (defining _toolkit_in_dll_ preprocessor definition and linking with dd_xx_dll 杔ib抯). when i use dd_vc8md_xx-lib抯 everything works fine (see no_dll_toolkit.jpg)
is that toolkit bug or do i miss something? dwgdirect version is 2.1.0

recalculate function is a database module functionality, so it is linked always with the application. differences can be only in available\unavailable plotsettingsvalidator.drx, but it take effect with not 'none' devices.
is it called in your dll project ?
:drxdynamiclinker()->loadapp(l"plotsettingsvalidator");
what is a device name in the layout ? try to set it to none and test again...
i add ?drxdynamiclinker()->loadapp(dd_t("plotsettingsvalidator"))?-call (after odinitialize 朿all) and now i try to set layout device name to 搉one?by using 損manager->setplotcfgname(newdwglayout, odstring("none"))? is that right method to do this?
but now paper background is even smaller than before (see dll_toolkit.jpg).

please, test if dd_gs_dll linked to your application. also check result of pmanager->setstdscaletype. i think that you have missed some module. i have tested your code with write_ex_dll project. it was ok.
yes, dd_gs_dll.lib is linked with our application. we links following modules:
dd_br_dll.lib
dd_acisbuilder_dll.lib
dd_acisrenderer_dll.lib
dd_modelergeometry_dll.lib
dd_db_dll.lib
dd_ge_dll.lib
dd_root_dll.lib
dd_gi_dll.lib
dd_alloc_dll.lib
dd_gs_dll.lib
dd_spatialindex_dll.lib
plotsettingsvalidator_dll.lib
and same folder with executable is following dll and drx files:
dd_acisbuilder.dll
dd_acisrenderer.dll
dd_alloc.dll
dd_br.dll
dd_db.dll
dd_ge.dll
dd_gi.dll
dd_gs.dll
dd_root.dll
dd_spatialindex.dll
modelergeometry.drx
plotsettingsvalidator.drx
setstdscaletype return value is not 0 (eok) it is 5 (einvalidinput).
-jpa
it return einvalidinput if
1. pplotset is null
oddbplotsettingsvalidatorimpl::setstdscaletype(
oddbplotsettings* pplotset,
const stdscaletype scaletype)
2. exception appears inside. for example if application cannot load module.
writeex also uses dd_bmpexport.dll, winbitmap.gs, rasterprocessor.drx, dd_spatialindex.dll.
i think that you need dd_spatialindex.dll at least. it is used in extents calculation.
and what is linked libs list for lib version of your app ?
problem is solved. we have old version of dd_spatialindex.dll on our application folder. my mistake.
-jpa
good news.
