Is there anyway to skip generating thumbnail when adding image to a new project?

[amor-volastra]

Hello,
I am creating a QuPath project to add some annotation as follow (to review them later in QuPath GUI):

 with QuPathProject(dir_to_proj, mode='a') as qp:
    entries = qp.add_image(dir_to_wsi)
    entry.hierarchy.add_annotation(roi)

some of my images (svs) are pretty large (>150k pixels) and it takes long time (15-25 min) to run add_image which I guess is due to creating thumbnail.
I was wondering if there is a way to skip thumbnail creation (not sure how necessary it is for QuPath to have thumbnail) or make it faster.

[ap--]

Hi @amor-volastra

Thumbnail generation shouldn't really take long...

Could you provide some information about your setup?
What operating system?
What python version?
How did you install paquo?
How did you install QuPath?
Does it take long to generate the Thumbnail when you do it manually in QuPath?

And could you provide an example file that is slow?

Cheers,
Andreas 😃
