技術スタック: javascriptnodejs
領域: backend
Issue 種別: bug
難度: 3
推定時間: 1-3 hours
活動状況: stale
明確さ: clear
前提条件: Node.js basicsBMP/JPG color handling
初心者向け度: 60
調査方針: Examine the BMP decoder in Jimp's source code to verify that pixel data is being read in the correct byte order. BMP files store pixels in BGR format, while JPG expects RGB. Check if there is a color conversion step. Reproduce the bug using the provided code and add debugging to log the pixel values before and after reading the BMP. Look for any existing tests for BMP to JPG conversion to understand expected behavior. Consider if the issue is specific to certain BMP images (e.g., those generated by online convert.com).
