Output as Buffer does an rotation #37

Open excedra opened 2 years ago

excedra commented 2 years ago

When outputting an image as buffer, it will be rotated by 90 degrees. Is this intended?

I suspect your image has rotation info in the EXIF data. I seem to remember seeing some issues with that and the underlying JIMP library. If you can provide sample image and demo flow I will attempt to understand and help you get this sorted.

No, this node uses the JJIMP library not sharp-image
