Expected Behavior

maintain color mode on save

Current Behavior

CMYK TIFF saved as JPG is RGB

Failure Information (for bugs)

A CMYK TIFF file read then saved as JPG is saved in RGB.

I have read a number of conflicting statements regarding the support for CMYK - one stated that jpeg-js does not support CMYK, which seems untrue (at least currently) - so how does jimp specify which mode for jpeg-js to save in?

研究方向: Investigate how Jimp handles color mode during save, specifically for JPEG output. Review the write method and how it interacts with jpeg js. Check if jpeg js supports CMYK and if Jimp explicitly sets the color mode. Look at the image object's mode property and how it's passed to the encoder. Consider adding a test case for CMYK TIFF to JPEG conversion.
