Performance Issue: Slow Creation of Deep Zoom Images (DZI) #30

Open Ryannn41 opened 5 days ago

Ryannn41 commented 5 days ago

Hello,

In our project, we are working on backend AI models to analyze pathology images. These images are typically large TIF files (around 500MB each). We use the create() method to generate Deep Zoom Images (DZI) for efficient visualization and zooming, but the performance is significantly slow when processing such large images.

I wanted to ask if you or others have encountered similar performance issues and are there any specific optimizations?

Check if your TIFFs are tiled. If not - tile them using https://github.com/darwinjob/ImageMagick-scripts or something similar.
