@volart It is probably the same problem. The JPEG is stored in landscape orientation and there is only some metadata telling viewers to correctly rotate it on display. In this case I would run a tool like jpegtran to correctly rotate the image before passing it to Prawn.

Thank you for the report.
Unlike JPEG, PNG is not a natively supported format in PDF. Prawn embeds JPEG images as is into the resulting PDF because JPEG is a natively supported format and all renderers should handle it properly. PNG, on the other hand, needs preprocessing. This is indeed a bug/missing feature of Prawn.

Hey folks! I have an issue with JPEG images' orientation. The situation is next: I have a service which uses prawn for pdf generation(obviously) and I upload some photos made by phone in portrait orientation. However, it is in landscape orientation in a pdf. Sorry if my message is out of the current conversation scope. I would appreciate it if you confirm the issue or point me to where I'm wrong.
