Recently I find that Windows mouse cursor is not very friently for left-handed people. Because it point from right to left.
So I wonder if there is a way to change it to "left to right". I searched the internet but havnen't found one.
Further search give me a message that the "cur" file format is a derivation of the "ico" format: https://en.wikipedia.org/wiki/ICO_(file_format)
So I think if we can flip it programatically.
Currently I can use these steps to modify one image:
- Copy C:\Windows\Cursors to a directory, then use the following script to convert to "ico" files so GIMP can recognize it
from pathlib import Path
CURRENT = Path(__file__).resolve().parent
CURRENT.joinpath("Cursors_ico").mkdir(exist_ok=True)
files = list(CURRENT.joinpath("Cursors").glob("*.cur"))
for file in files:
dest = CURRENT.joinpath("Cursors_ico")
data = file.read_bytes()
data = bytearray(data)
data[2] = 0x01
dest.joinpath(file.stem + ".ico").write_bytes(data)-
use GIMP to flip this step isn't very intresting. I will have to delete all other layers, and use selection to select the cursor, and use "Layer -> Transform -> Flip horizontally". Then export ico file. Also the hotspot location has changed so we need to remember its location.

convert back to "cur" file script:
from pathlib import Path
file = Path("aero_link.ico")
data = bytearray(file.read_bytes())
data[10] = 102 # hover on the finger and you can see the location in the GIMP bottom pane. fill it here
data[2] = 0x02 # change the file header back
Path("aero_link.cur").write_bytes(data)- Load file In settings - bluetooth & devices - mouse - additional mouse settings - pointers, create a new scheme, and change the "link select" image
I wonder if we can do the step 2 automatically
Also there is a display bug for Microsoft Windows's Window manager:
if you move cursor to top-left corner, it will cause the screen goes black, plus taskbar and video playback issues
