After resize the image is rotated about thumbnailator HOT 3 CLOSED

@BaolCristian, the issue here is that the JPEG file has Exif metadata that contains the orientation information, so the original pixels stored in the image is actually rotated, as seen in the image shrunken by Thumbnailator.

The reason for this is that you're reading the image to a BufferedImage before handing it to Thumbnails.of. Thumbnailator will detect the Exif metadata and apply proper rotation to give the correct orientation as long as the JPEG file is given to Thumbnails.of.

Therefore, if the code was rewritten as:

InputStream is = new BufferedInputStream(img.getBinaryStream())
def result=Thumbnails.of(is).size(600, 600).asBufferedImage()

This should end up with the correct orientation for the thumbnail.

Inspecting with exiftools shows that orientation information is removed as a result.

I will be closing this issue as a resolution has been provided.
