            QPainter rotation prevents correct QPixmap rendering
            Asked 2021-May-06 at 14:43

            Reported to Qt as a bug: https://bugreports.qt.io/browse/QTBUG-93475

            I am re-drawing a QPixmap multiple times in different locations, with differnt rotations by transforming the QPainter. In certain situations the QPixmap is not drawing correctly. The GIF below shows my initial discovery of this issue with a QPixmap containing a green cylinder, notice how the rendering behaves as expected to the left of the GIF, but there is a boundary beyond which the rendering is incorrect. The QPixmap content appears to stick in place, and the pixels at the edge appear to smear out accross the rest of the pixmap. In the GIF there is a magenta background to the QPixmap, this because the targetRect used by QPainter::drawPixmap() is also beuing used to seperately fill a rectangle underneath the pixmap, this was because I wanted to check that the target rect was being computed correctly.

            Minimum reproducable example:

            To keep things simple I am simply filling the QPixmap with magenta pixels, with a 1 pixel wide transparent edge so that the smearing causes the pixmaps to dissapear completely. It doesn't show the image "sticking" in place but it clearly shows the boundary as beyond it the pixmaps seem to dissapear.

            I have been experimenting with this myself and I believe this to be entirely caused by the rotating of the QPainter.

            The angle of rotation seems to have an effect, if all of the pixmaps are rotated to the same angle then the boundary changes from a fuzzy diagonal line (where fuzzy means the boundary for dissapearing is different for each pixmap) to a sharp 90 degree corner (where sharp means that the boundary for dissapearing is the same for all pixmaps).

            The range of different angles also seems to play a part, if the randomly generated angles are in a small 10 degree range, then the boundary is just a slightly fuzzier right angle, with a bevelled corner. There seems to be a progression from sharp right angle to fuzzy diagonal line as the number of different rotations is applied.

            This issue is very interesting. As far as I could test, your code looks good, I feel like this is a Qt bug, and I think you need to report it to Qt: https://bugreports.qt.io/. You should post a single piece of code to illustrate the issue, your second one from your "Update" edit is good: it makes it easy to reproduce the issu. Maybe you should also post a small video to illustrate how things are getting wrong when you zoom in/out or move the area with the mouse.

            I tried some alternatives to hopefully find a workaround, but I found none:

            • Tried to use a QImage rather than a QPixmap, same issue
            • Tried to load the pixmap from a frozen png/qrc file, same issue
            • Tried to use QTransform to play with scale/translation/rotation, same issue
            • Tried Linux and Windows 10: same issue observed

            Note that:

            • If you don't rotate (comment paint.rotate(entity.rotation_);), the issue is not visible
            • If your pixmap is a simple mono-colored square (simply fill your pixmap with a single color using pixmap_.fill(QColor::fromRgba(0x12345600));), the issue is not visible anymore. That's the most surprising, looks like a pixel from the image is being reused as background and messes things up but if all the image pixels are the same it does not lead to any display issue.

            Quoting Wisdom

            IP cameras are of varying quality, some behaving erratically in my experience. Dealing with their RTSP streams requires a dose of fault-tolerance.
            This appears to be a byproduct of the low-end of the CCTV industry playing fast and loose with standards, RTSP and ONVIF being the two most frequently abused. Fortunately, you can usually work around these problems. Unless your IP cameras and controller are all designed to play nicely together, only use ONVIF for once-only discovery and settings management.

            FFMPEG not very tolerant in RTSP setup

            After struggling I started comparing the RTSP/SETUP messages between openRTSP and ffmpeg. openRTSP by default already outputs a lot of verbose diagnostic.

            openRTSP sends the commands OPTIONS, DESCRIBE and then SETUP. The SETUP messages were:

            Plot stochastic trajectories deviations from 'real' path using a colormesh in matplotlib (Python)
            Asked 2021-Mar-16 at 13:50

            Hi I created a program that will create deviations from a real trajectory, it is complicated and I do not have a simple example unfortunately.

            It calculates a path with stochastic initial conditions from the real path and does this for x iterations, the goal is to show that the deviations become larger at greater times.

            The real path and the deviations are showed below.

            However I want to show that the deviations become greater the longer in time we are. Ofcourse I could just calculate the variance and plot mean+var and mean-var at each time step but I was wondering if I could plot something like this, using hist2d

            You see that the blocks are not as smooth as a like and this is not that great to use.

            Then I went and looked at python's kde and created the following.

            This is also not preferable as I think it bins more points at the minima and maxima. Also it is 'too smeared out'. Especially in the beginning, all the points are the same so I want there just to be a straight line to really show that the deviations start later on.

            I guess my question is; is what I want even possible and what package/command should I use. I haven't found what I am looking for on other questions. Or has anyone a suggestion to nicely show what I want in a any other way?

            You could use something like the matplotlib.pyplot.fill_between method. It fills everything between y1 (max) and y2 (min) for a given (common) x array. You would then be able to accentuate that the filled region keeps enlarging with increasing x value.

            However, this would require you to find the minimal and maximal value of your deviations at each time point and save these to two separate arrays. The exact method of doing this will depend on how you are storing these individual runs.

            In case they are separate lists / arrays, you can convert these to a numpy matrix / pandas dataframe and use the minimum / maximum methods along the relevant axis.

            Assuming you don't want the option that I used in the linked post, the other way that you can approach this is adding the CheckBox to the header of the ListView.

            Using SendMessageYou can send LVM_GETHEADER message to the listview control and get the handle of the header, then SetParent will help you to set the header as parent of checkbox:

            Asked 2020-Dec-12 at 23:47

            This is a weird smearing effect I've never seen before in rendered matplotlib figures that looks like a printer error. I'm not clear on what might be causing it. I'm processing a sizeable dataframe (4.5gb) to render two copies of the same figure generated from each row, filenames are derived from the data which is why they're not simply copied and renamed after the process.

            Here's a simpler version with np.random instead of the dataframe:

            I would like to "crop" the dress and get just the portion of the first image contained in the black circle. I tried many different methods but they didn't work or are too slow:

            I am interested in a ImageMagick solution if possible.

            The provided solutions work fine if the mask is smaller than the original image and if the original image is simple. With these source image and mask the result is "smeared":
