QUESTION
I've got a .net API and my Program.cs has started to become quite bloated with the following:
...ANSWER
Answered 2022-Mar-22 at 12:55To answer your first question you can move the service registration to another class by creating a new class and having the method take in the builder and register services then return or create an extension method. Creating an extension method is slightly "neater" and you can do it like so.

I'm writing a class that grabs frames from basler USB cameras using pylonAPI and converts them to openCV format. Here's the code of the grabbing method:
...ANSWER
Answered 2022-Feb-09 at 13:37the problem here is, that the Mat constructor using an external pointer is NOT refcounted. once you leave the GrabPair function, both Mat's are invalid (dangling pointer)
you need to clone() them (deep copy of the data !) e.g. like:

I am developing a GUI of 4 using Basler cameras. Within my program, I am facing two problems that cause the GUI to fail to run properly. However, The main goal is to save 4 images based on the camera index. I was told to use the multi-threading technique to develop the GUI, and these are the problems I encountered. These are the codes:

Answered 2021-Nov-29 at 10:51In below code, the last line assign image[CamIdx] from opencv image to become ImageTk.PhotoImage which cv2 can not write down. Consider storing image[CamIdx] to another varible before assigning image[CamIdx] = ImageTk.PhotoImage(image = Image.fromarray(image[CamIdx])).
QUESTION
I am working on a Pylon Application where performance is crucial , saving images directly to the disk might throttle the performance, so I want to allocate a memory buffer where I can store an array of Pylon Images, and save them to disk later, what is the best approach I could take?
...ANSWER
Answered 2021-Nov-20 at 07:00I have managed to solve it by making an array of type (Pylon::CPylonImage) and save the captured images on it using a converter (Pylon::CImageFormatConverter) like the following code block
QUESTION
I am using a cookiecutter to make a pyramid web app. It has a function to seed the db here: https://github.com/Pylons/pyramid-cookiecutter-starter/blob/latest/%7B%7Bcookiecutter.repo_name%7D%7D/%7B%7Bcookiecutter.repo_name%7D%7D/sqlalchemy_scripts/initialize_db.py#L15
But if I run it twice, or change the entries that I am adding, I get duplicate entries and errors. I am using a sqlite db with sqlalchemy.
What code can I add inside setup_models that will drop db all db rows before writing the new model instances? It would be great if this looped over all models and deleted all instances of them.
...ANSWER
Answered 2021-Sep-17 at 21:23By default, SQLite does not enforce foreign key constraints at the engine level (even if you have declared them in the table DDL), so you could probably just use something as simple as
QUESTION
I want to show a list of ICameraInfo in a ComboBox.
ICameraInfo is an interface that give you many infos of a camera. You get each info using indexer.
In my case I want to display the parameter ICameraInfo[CameraInfoKey.FriendlyName] in the ComboBox (CameraInfoKey is a static class).
In ViewModel:
...ANSWER
Answered 2021-Aug-14 at 21:09If ICameraInfo does not have FriendlyName property that you want and you must get the actual value from an indexer property, I don't think that DisplayMemberPath is the way for you to go. Instead, you should probably layout the ItemTemplate for your ComboBox and in it, have a TextBlock that pulls the string value. You could even use a converter for this if necessary. For example, something like this:
QUESTION
i am working on bayer images. i use basler camera and i get bayerBG8 image from it. in pylon i can directly converted to RGB, but i want to save the bayer image so i need to specify its channels to define a mat file. when i use 1 channel for it i get gray scale image and if i choose more than on channel, images repeated in one frame as shown:

Answered 2021-Jul-27 at 11:07Bayer filter is a technique to use a single-channel image sensor to receive color image by defining which pixel should represent which color, so a bayer image should have one channel.

I have a problem with live video stream from 2 GigE cameras in QML. I tried it before with QLabels and QPixmap and it worked without any problem. The QML Labels don't have pixmap property to send images using signal slots.

I'm trying to make my bot welcome someone whenever someone joins but I can't seem to get it to work. For example(this will appear in an embed by the way):
...ANSWER
Answered 2021-Mar-04 at 21:22The documentation fo GuildMemberJoinEvent clearly states:
RequirementsThis event requires the GUILD_MEMBERS intent to be enabled. createDefault(String) and createLight(String) disable this by default!
So you must enable the intent. Read more in the wiki guide Gateway Intents and Member Cache Policy
Additionally, you have a nested class for no reason which means you register the enclosing class as a listener but not the nested class that actually implements it.
