[Closed] Make Viewport snapshot

something like this ?

fn viewport_snapshot fname frame =
(	
	snapshot_name = (getDir #preview)+"/" + fname;
	view_size = getViewSize()
	anim_bmp = bitmap view_size.x view_size.y filename:snapshot_name
	sliderTime = frame
	dib = gw.getViewportDib()
	copy dib anim_bmp
	save anim_bmp
	close anim_bmp
	gc()
)

viewport_snapshot "temp.jpg" 30f

Thx!

Sometimes it’s impossible to find those things in max help…

I’m after the same but SDK. I almost have it sorted from the example but getActiveViewport() is not use in the interface class? It is grayed out? Looke in all the other and can’t find where they moved it to?

void BasicTools::Image(){
	BITMAPINFO *bmi = NULL;
	BITMAPINFOHEADER *bmih;
	BitmapInfo biFile;
	Bitmap *map;
	int size;
	TheManager->SelectFileOutput(&biFile,ip->GetMAXHWnd(), _M("Testing"));
	if(!biFile.Name()[0])
		return;
	ViewExp* view = ip->getActiveViewport();
	view->getGW()->getDIB(NULL, &size);
	bmi = (BITMAPINFO *)malloc(size);
	bmih = (BITMAPINFOHEADER *)bmi;
	view->getGW()->getDIB(bmi, &size);
	biFile.SetWidth((WORD)bmih->biWidth);
	biFile.SetHeight((WORD)bmih->biHeight);
	biFile.SetType(BMM_TRUE_32);
	map = TheManager->Create(&biFile);
	map->OpenOutput(&biFile);
	map->FromDib(bmi);
	map->Write(&biFile);
	map->Close(&biFile);
	if(bmi)
	free(bmi);
	ip->ReleaseViewport(view);
}

I did see in interface7 there is…
But this give me an error on ip7->SetActiveViewport

int MyView = ip7->getActiveViewportIndex(); 	
ViewExp* view = ip7->SetActiveViewport(MyView);	

Also not seeing a ip->ReleaseViewport(view); in any interface class.

Any thoughts

an mxs function would look something like this, you should be able to convert it

Value* saveViewport_cf(Value** arg_list, int count)
{
	check_arg_count(saveViewport, 1, count);

	ViewExp *vpt = MAXScript_interface->GetActiveViewport();
	GraphicsWindow *gw = vpt->getGW();
	BITMAPINFO *bmi = NULL;
	BITMAPINFOHEADER *bmih;
	BitmapInfo bi;
	Bitmap *bmp;
	int size;
	gw->getDIB(NULL, &size);
	bmi  = (BITMAPINFO *)malloc(size);
	bmih = (BITMAPINFOHEADER *)bmi;
	gw->getDIB(bmi, &size);
	bi.SetWidth((WORD)bmih->biWidth);
	bi.SetHeight((WORD)bmih->biHeight);
	bi.SetType(BMM_TRUE_32);
	bmp = CreateBitmapFromBitmapInfo(bi);
	bmp->FromDib(bmi);
	free(bmi);	
	MAXScript_interface->ReleaseViewport(vpt);
	bi.SetName(arg_list[0]->to_string());
	bmp->OpenOutput(&bi);
	bmp->Write(&bi);
	bmp->Close(&bi);
	bmp->DeleteThis();  

	return &ok;
}

Ok really dumb question what is this “mxs function” is this for function publishing? I remember putting a function in your [useful mxs function] thread and you asked what does this have to do with mxs function.

mxs is short for maxscript, and a sdk mxs function is a function that extends maxscript via a dlx plugin. see the mxsagni project in the samples

So I guess the question I would have now is how would I get…
ViewExp *vpt
and then Release it.

ip7->GetActiveViewExp();
is close but does not give me a pointer

No error but big crash

void BasicTools::Image(){
	int viewPanelIndex = 1;
	int index = 1;
	IViewPanel* pPanel = GetViewPanelManager()->GetViewPanel(viewPanelIndex);
	BITMAPINFO *bmi = NULL;
	BITMAPINFOHEADER *bmih;
	BitmapInfo biFile;
	Bitmap *map;
	int size;
	TheManager->SelectFileOutput(&biFile,
	ip->GetMAXHWnd(), _M("Testing"));
	if(!biFile.Name()[0])
	return;

	ViewExp *vpt = nullptr;
	vpt = pPanel->GetViewExpByIndex(index).ToPointer();

	vpt->getGW()->getDIB(NULL, &size);
	bmi = (BITMAPINFO *)malloc(size);
	bmih = (BITMAPINFOHEADER *)bmi;
	vpt->getGW()->getDIB(bmi, &size);
	biFile.SetWidth((WORD)bmih->biWidth);
	biFile.SetHeight((WORD)bmih->biHeight);
	biFile.SetType(BMM_TRUE_32);
	map = TheManager->Create(&biFile);
	map->OpenOutput(&biFile);
	map->FromDib(bmi);
	map->Write(&biFile);
	map->Close(&biFile);
	if(bmi)
	free(bmi);
	// ip->ReleaseViewport(vpt);
}

GetCOREInterface()->GetActiveViewport();
