During May 2025, Andrey Orlenko focused on improving image decoding reliability in the libsdl-org/SDL_image repository. He addressed a recurring issue where certain WebP images were misidentified as TIFF by modifying the internal image source creation logic in Objective-C, specifically by passing NULL to CreateCGImageSourceFromIOStream and removing the hint dictionary in the Internal_isType path. This targeted bug fix, leveraging Core Graphics and image processing expertise, reduced user-visible decoding failures and enhanced runtime stability for WebP workflows. The change was low-risk, scope-limited, and maintained API stability, reflecting a careful and effective approach to internal library maintenance.

May 2025 monthly summary for libsdl-org/SDL_image: Delivered a high-priority bug fix that improves WebP decoding reliability and prevents misclassification as TIFF. By passing NULL to CreateCGImageSourceFromIOStream in IMG_ImageIO.m and removing the hint dictionary in the Internal_isType path (commit e28c7c7623ed447c10977849013c6e3c815f0788), the change eliminates a recurring image-identity bug and reduces user-visible decoding failures. The change is low-risk, scope-limited, and affects only the internal image source creation flow. This work enhances runtime stability across WebP workflows, reducing support overhead and improving developer and end-user trust in SDL_image.
