Manual tilt series with 2kx2k images

[ercius]

Describe the bug The manual tilt series GUI shows the current projection image as white if the tilt series is as large as 2048x2048.

To Reproduce Steps to reproduce the behavior:

1. Create a tilt series with 2048x2048 images and save as npy
2. Load the data file
3. Set as tilt series
4. Open manual tilt series GUI. The image in the upper left is pure white.

aa = np.zeros((2048,2048,5),dtype=np.uint8,order='F')
aa[0:100,0:100,:] = 100 # make it not all zeros
np.save(Path.home() / Path('test.npy'),aa)

Expected behavior The projection image should be shown

Screenshots Area to the left of the instruction should show a projection image

Here is the same data binned x2:

@ercius How many slices? Is the application still responsive?

[ercius]

@cjh1 the test tilt series I generated has about 5 slices. The user's tilt series which made me aware of this problem was about 25 slices.

The GUI was responsive. The lower images changed when changing inputs.
