Define a minimum output size?

[Arvkon]

Instagram photos are 640 x 640 pixels in size. I would like to make this the minimum size that an image can be cropped to. Could you (or anyone) suggest how I might go about achieving this?

Hello Arvid,

Sorry for the delay.
I will think about it in the coming weekend.
Currently, you can try to add the following code to this line:

if (boundsSize.width < boundsSize.height) {
    maxScale = MIN(maxScale, boundsSize.width / 640.0);
} else {
    maxScale = MIN(maxScale, boundsSize.height / 640.0);
}

Sincerely,
Ruslan

Update (29/11/2017):

Additionally, you must handle the case where the size of the original image is smaller than the minimum output size.

You, sir, are a gentleman! Your suggestion worked like a charm =)

I made a fork with your code and a minOutputSize property: Arvkon@e590f8a

How to set Min and Max Zoom in Swift ?

i see that this has still not made into the master. Is there plans to move it?

No. There aren't.

You should not limit the size of the image when cropping.

Instead of this, to get an image with the specific minimum size you need to use RSKImageCropper to crop the original image and then if needed manually scale the cropped image up to the minimum output size. This will allow the user to select any desired part of the image.
