Unexpected image rotation during resize

My generated images are always “horizontal” (larger in width) even when the input was “vertical” – for instance, an upright phone picture.

My resize code is basically:

sharp(originalImagePath)
    .resize(200, 200) // to make a small thumbnail
    .min()
    .toFile(outputImagePath);

“If no angle is provided, it is determined from the EXIF data.”

If there’s no EXIF data, or if the EXIF data states there should be no rotation, then none will occur for a parameter-less call to rotate().

@lovell rotate() works but it is increasing my buffer size a few times
