Rotate Reduces Resolution #6

Closed ghwilley closed 3 years ago

ghwilley commented 3 years ago

There's no way to rotate an image and retain its resolution. So if you have an image that's 1000 x 500 and go from landscape to portrait, the height of the image will be 500. If you then eliminate the white space on the sides, it's now 250 x 500.

Use renderAtNaturalSize if you want to preserve the original resolution. More info here.

Thanks for the fast response!

I am finding that even with renderAtNaturalSize set to true, if I rotate an image, I can not keep the original dimensions. Max height will always be the images original height, and max width will be the images original width.

Steps to reproduce:

Upload a non-square image.
open cropro and rotate the image.
commit the rotation.
open cropro and rotate the image back to it's original orientation.
commit the rotation.

The image is now smaller than when it was uploaded.

Yes, you are right. I will look into it. Thanks for reporting this!

Fixed this for renderAtNaturalSize scenario. When it is set to false, I think rendering to what you see on the screen is the correct behavior.
