About me

Hello everyone, I am Vincent, a QA Software Engineer in Canonical.
I'm now focusing on the testing automation.
I love challenges because it always makes me stronger.
As an Engineer, I find the problem, I face the problem, and I solve the problem.

imagetoolbox's Issues

Features for File/Folder management

Currently in 10-bit depth raw image files processing, I often confront some cumbersome file/folder management issues, such as iteratively converting huge-amount 10-bit-Raws to CSVs from specific folder directories and save to another directories. Afterward, I use these CSVs sequentially generating another CSVs (eg. the pixel-wise mean of the CSVs in the last step) , and so on...

During the conversion, I also frequently confront the lack of disk space.

I recommend add the following features:

1. SelectLoadDirectory()
2. SelectSaveDirectory()
   the design and architecture of functions( args, return values, ...) can be determined later
   after discussion.

(1) and (2) can refer to this snippet:

import tkinter as tk
from tkinter import filedialog

root = tk.Tk()
root.withdraw()
root.call('wm', 'attributes', '.', '-topmost', True)
rawPaths = filedialog.askopenfilenames()
rawPaths=list(rawPaths)
savePath=rawPaths[0].replace('/'+rawPaths[0].split("/")[-1],"")
savePath=(savePath+'/csv_unsigned')
if not os.path.exists(savePath):
    os.mkdir(savePath)
    print('csv folder built')

3.Build a function dynamically detect the disk space, when the space is insufficient,
interrupt the operation waiting for the release the suffient space.
After having sufficient space then the function automatically recover the interrupted operation before.

(3) can refer to this snippet:

import ctypes
def get_free_space_mb(dirname):
    """Return folder/drive free space (in megabytes)."""
    if platform.system() == 'Windows':
        free_bytes = ctypes.c_ulonglong(0)
        ctypes.windll.kernel32.GetDiskFreeSpaceExW(ctypes.c_wchar_p(dirname), None, None, ctypes.pointer(free_bytes))
        return free_bytes.value / 1024 / 1024
    else:
        st = os.statvfs(dirname)
        return st.f_bavail * st.f_frsize / 1024 / 1024
