You can do a data structure of 16gB using the range of signed indexes for
doubles. That should plenty.
I do still miss the python negative syntax though. [-1] and

So that the software can plan accordingly. Blindly executing won't allow the

I have a application running on an Ubuntu 16.04 Box. I want to get the window

Simple code:
cv::Mat left_image = cv::imread(filename, cv::IMREAD_COLOR );
cv::cvtColor(mat, mat, cv::COLOR_BGR2GRAY);
cv::imwrite("dummy_gray_cv.png", left_image); // ok

That indeed seems to be the case. But this is very interesting for Grayscale. RGB888 is fine. Maybe this is more a OpenCV question, why would the BPL not equal pixels per line?

You can bind to a specific interface, but if you use Any, then it's up to the

I think you're running into a NAT router (network address translation)
You can configure your router to not do this, but that requires you to have an
addressable network. NAT is generally used with cable modems because you only
get the IP pf the modem. Then the kernel on the router takes care of

So I've been providing a function and doing:
MySingleton::instance()->emitMySignal();
Where:

So there's a couple ways in iOS to get the SSID. But I was hoping, since I need
to target android as well, that I can have a Qt solution that "just works"
complete with SSID change monitoring. There's two APIs: NEHotspotHelper which
requires and entitlement or CaptiveNetwork which was deprecated
Maybe you should use qRgb() or qRgba(...) and let it put the bytes where it wants? also, note that there are qRed(), qBlue(), qGeen(), and qAlpha() which should take care of extracting the aproproate channel for you.
If you told me that in Qt, BGR32 (and BGRA32) is 0xAABBGGRR, I would agree.

Curious, when it crashes like that, are you in the debugger?
When I use the camera in Qt on OSX, in normal run mode, it works. Only when I . use the debugger it crashes with the permission message.
Also, what are you doing to provide the application PLIST? I have not done that successfully app
oid and iOS.

I an starting to see QHostAddress::toString() return things like:
":::192.168.34.3", which is a IPv6 mapping.
However when I try to connect to this address it does not work. That server is
a QTcpServer bound as:
_server.listen(QHostAddress::Any, PORT);
When the QHostAddress resolves to a IPv

Does anyone know how to handle this? I'm not sure who is using which version.
What I did: linked OpenCV into an iOS Qt app. Tape a picture and onImageSaved
handler, set an Image element source property to "file://"+path, then it
crashes immediately.
Works fine in Android.

When assigning an image element to an image capted from a Camera, it is not
sufficient to just assign the `path` to the source of the Image element that is
to display it:
qrc:/main.qml:100:4: QML Image: Cannot open:
qrc:/var/mobile/Containers/Data/Application/8BD0A3CA-74AA-4599-BCF5-E1863AEA688F

That happens when QML can't create the entire object hierarchy.
This can happen when you have a syntax error, or there is some failure to load
a component.
I would suggest looking at if you are referencing some hardware component on
the device that doesn't exist or is otherwise broken.

I've been encountering an increasing number of issue that are crashes, that
become fixed, but not back-ported to 5.12.
I was under the impression that LTS would include this type of issue.
Apparently, I am misinformed. I have reviewed the blog posts:

After reviewing the QWebSocket spec ( https://tools.ietf.org/html/rfc6455 )
text frames are supposed to be UTF-8 encoded, which would mean that QByteArray

Now I'm having to toUtf8() all the things I receive, and QString() the ones I

I'm here watching Ulf's QtWS19 QML talk and had a thought...
I might be dumb or crazy (either are equally likely) but, the other day I added
a property called 'data' and completely broke my application. It was to store

Just how invalid are we talking?
It's well-known that the blue/red channels may be swapped, and I've seen
padding on the row.
Doing your math though you're only reporting 2 bytes per pixel, which is very
wrong. What is the image format you expect?

I don't know if it is possible, but OpenCV could probably do it. Not sure if
2vuy is in their list. Have a look at
https://docs.opencv.org/3.4/d8/d01/group__imgproc__color__conversions.html#ga4e0972be5de079fed4e3a10e24ef5ef0
This should be hardware accelerated to some degree...
