QUESTION
As the title says. It seems that Avalonia Bitmap requires file path, so the only solution that comes to my mind is saving image, and then displaying it. But it's not exactly what I want to do, I would want to directly display the image from memory.
...ANSWER
Answered 2022-Mar-22 at 06:04You can save the Image's data into a memory stream and pass it in to Avalonia's Bitmap.

I'm trying to perform a skull stripping with simpleITK in python. I'm using the StripTsImageFilter function as follows:
...ANSWER
Answered 2022-Feb-23 at 16:22StripTsImageFilter is a 'remote' module for ITK. So it is not wrapped by SimpleITK and is not even built by default in ITK.
To gain access to it in Python you're going to have to use ITK's Python wrapping, and you're going to have to build ITK-Python yourself, since it is not in the pre-build ITK-Python on PyPi.

QUESTION
Context: I've got a WebApp (frontend: Vue3, backend: node.js + express) with a single vue, and a button. When clicking on a button it triggers a script in the backend, downloading an image, and storing it locally. This image should be rendered on the Vue side.

Answered 2022-Jan-29 at 05:21Since you want to use the updated value in another object( basically trying to share the value between multiple objects), you should keep your variable hdr_dir as static. Static vs Instance Variables: Difference?
You were currently using the variable as instance one due to which if one object updates the value, it will remain specific to that object only. For your main class,

QUESTION
I'm trying to flip a BMP image in C. I ran into a problem where when I try to read the BMP header everything is alright and the values are correct, but when I try to read the DIB header I get all of the values right except for the image size (raw bitmap data). I get a zero, which is really weird considering I got the file size in the BMP header. I tried debugging the code and looking up the problem online but that didn't help much.
This is my code:
...ANSWER
Answered 2021-Dec-12 at 12:59The format expect the structure size to be 14 and 40 for BITMAP_header and DIB_header. But the compiler aligns the structure and the size will be different. You have to use compiler specific flags to disable structure alignment (it's unclear which compiler you use). It's the same problem with RGB structure.
There is also endian-ness dependence, and the fact that bitmap doesn't store pixels in RGB format, it flips the bytes.
