Itom 4.3dev: Scrolling through image stack gets stuck when using arrow keys
Opened this issue · 0 comments
Small issue in Current Dev-Version 4.3dev:
This happens when the following is done: Having a 3D numpy.ndarray in the Global Variables (idk if that is also the case with dataObjects), selecting it and clicking on the icon for a "2D image plot", i.e. opening a plot. When scrolling quickly through the image stack (for displaying the image stack as somewhat of a video) at "Select image plane" using the up and down arrow keys (by holding them) leads to the scrolling getting "stuck" at a particular image sometimes.
Most of the time this happened when a fast change between up/down keys occurs, most prominently when reaching the first or last image in the image stack (of course changing the scrolling direction of the keys is a natural move there).
The image plane being stuck cannot be undone by pressing the arrow key again but rather by using the mouse wheel for scrolling while hovering with the cursor above the image plane number at "Seleect image plane". Using the arrow keys is possible again afterwards. Another way of fixing the "stuckness" is also by just typing in another image plane number and then using the arrow keys afterwards.
