Hide and Show the cropper selection

[Michael B]

Wonderful work Dave!

I am using displayOnInit: and onloadCoords: when I want to pass in
pre-
set crop values when the cropper loads.


However, once the page loads, I have a situation where I want a
toggle
to show or hide the cropper depending on the state of a checkbox on
my
form.


When I hide the cropper, I want to store the last coordinates so if
the cropper is made visible again, then the previous selection is
visible.


I think I want to use some combination of removeCropper and
resetCropper, but with coordinate values on the reset.


I have been unable to call attacattachCropper(); again after the form
has initially loaded.


Thanks in advance for any assisstance.

If you've got the co-ordinates stored then you could call the
setAreaCoords() method when you want to re-display it (after calling
resetCropper). This method is meant to be private, but that's the only
way of doing what you want at the moment.

I can't seem to get that suggestion to work and I am not exactly sure
how I should be calling this... Here is what I am doing:

this.curCrop.reset();
this.setAreaCoords( {x1: 10, y1: 10, x2: 100, y2: 300},true,false);

Ok. I figured it out.

It works fine when I call it like this:

this.curCrop.reset();

var previousCoords = { x1: prevX1, y1: prevY1, x2: prevX2, y2:
prevY2 };

this.curCrop.setAreaCoords( previousCoords );
this.curCrop.selArea.show();
this.curCrop.drawArea();
this.curCrop.endCrop();
