Areas of Expertise

Imaging and Engines.

Summary

User claims in thumbor/thumbor#1367 that images are showing blurry when compared to photoshop. We need to work with him to understand what's going on and either fix it or close it.

Involved Modules

• thumbor - pil engine

Task Relevance

Returning high-quality images from transformations is a key capability for thumbor. We must be vigilant that it's always the case.

Further Details

We should get the same source images the user is using, create a thumbor.conf that matches what they're saying, run thumbor and check that the transformation is indeed worse than Photoshop.

Proposed Solution

Before having a proposed solution we need to reproduce the problem.
