Change only orientation keeping other head as is #121

Closed hnviradiya closed 4 years ago

hnviradiya commented 4 years ago

Is it possible to maintain metadata by only changing orientation?

I have created following jsbin where when I replace head, it is losing orientation. Is there a way to fix this?

I have created question on stack overflow.

Yes you can, with the exif writer functionality: https://github.com/blueimp/JavaScript-Load-Image#exif-writer

Oh. Why did i think that other functions were of no use to my current requirement. I spent lot of time to figure out. Sorry to create this issue. And thanks a lot for your prompt response.

Got that fixed. orientation: 1 was still required: { meta: true, orientation: 1, canvas: true }
