Investigate the TIFF to JPEG conversion path in Jimp. Start by examining the TIFF decoder and JPEG encoder in the source code (likely in packages/jimp/src or similar). Check if the issue is related to color space handling, alpha channel, or image dimensions. Reproduce with a sample TIFF image to isolate whether the problem is in reading TIFF or writing JPEG. Look for any existing tests for TIFF conversion and ensure the bug is reproducible with the provided code snippet.
