Rotating image #24

Open AlexBacich opened 6 years ago

AlexBacich commented 6 years ago

Is there a possibility to add image rotation feature? So it can be 90, 180, 270 degrees rotated. Not quite familiar with image resizing logic so asking as feature request.

If you just want to rotate images, you can always use this library: https://github.com/brendan-duncan/image

The only real problem this library tries to solve is copying the whole image in a dart array which takes a lot of time.

So if you just want to rotate images, which are not that big, your best bet is to use that library.

Otherwise I will leave it open as a feature request.

Yes, I was using image library originally. With 3MB image it took 7 seconds to rotate which was an overkill. So now I'm using flutter_native_image to scale it first, and then rotate scaled version. Time decreased to 1s total.

Using 2 libraries still adds extra step of saving temporary file so having one library would be great.
