determine lowset zoom

[bharatpatil]

Is there any way to identify that we are on lowest possible zoom so that I can execute another function?

actually I wanted to execute a code to fit complete image inside crop area upon on lowest possible zoom

Yes, the property minPercent of the cropbox data (I will document this).

So you would do:

$('yourimage').data('cropbox').minPercent

This property will only be populated AFTER the image has been loaded by the browser (otherwise it can't be computed). Therefore I suggest you query for the property inside the the cropbox event, like this:

$('yourimage').on('cropbox', function (event, result, cropbox) {
   console.log('lowest zoom is ' + cropbox.minPercent);
});

Wow!! Thanks for such a nice plugin.
Sorry for my wrong question, my question should have been how to identify when I am zooming out if I am on lowest zoom. Once I am on lowest zoom inside zoomout function and again user tries to zoom out 2nd time I wanted to fit image inside cropbox viewport.

I hope you got my question..!!

I don't think I understand you. The image should always be "fit" inside the cropbox viewport.

If you want to zoom out beyond the boundaries of the image (i.e. you want part of the cropbox to have empty space), then this is unsupported by this plugin. You are welcome to submit a pull request implementing this feature, but it should be optional since most people don't want that behavior.

Yes you are correct but I have such a requirement then I will be setting image width:auto / 100% and height:auto / 100% depending upon the image ratio.
