Hi Danny,
I'm using OSG inside of ActiveX control (based on OSGActiveX example) embedded into HTML
page. First time when I'm loading it and each time I'm taking snapshot, I'm getting
"test_0.png" and each snapshot overwrites this file.
When I'm pressing F5 or reloading page using IE address bar I'm starting to
save snapshots as test_1.png and each snaphot overwrite this file.
This behavior continues each time I'm reloading page. the counter is being
incremented by one to test_2, test_3 etc....
the only solution for this problem is to close IE and to wait till ActiveX
unloads from Memeory. after it the counts start form zero.
Check the code for osgViewer::ScreenCaptureHandler::WriteToFile in
src/osgViewer/ScreenCaptureHandler.cpp. There must be a bug there. It's
pretty simple code, so you can make your own version of WriteToFile that
does whatever you want, and then use an instance of your class in the
constructor of ScreenCaptureHandler.
// pseudocode
class MyWriteToFile
: public osgViewer::ScreenCaptureHandler::WriteToFile
{
MyWriteToFile(filename, extension, savePolicy)
: osgViewer::ScreenCaptureHandler::WriteToFile(filename, extension,
savePolicy)
{
// ...
}
operator()(...)
{
// ...
}
// ...
};
// then...
osgViewer::ScreenCaptureHandler* _scnsvr;
_scnsvr = new osgViewer::ScreenCaptureHandler(new
MyWriteToFile("test","png",osgViewer::ScreenCaptureHandler::WriteToFile::SavePolicy::OVERWRITE));
(if you do find a bug in the existing code please let us know so we can
fix it for future versions of OSG though)
Hope this helps,
J-S
