Make Jcrop tracker not rotate when cropping a rotated image

Question

I\'m trying to crop an image using Jcrop, but when I use jqueryrotate on the image, something weird happens.

I rotate the image 90 degress then I activate the JCrop,

Answer 1

Yes, the JCrop has the problem of selection direction error after rotated by JQuery rotate. I had to resolve it by change the JCrop's js code to support rotate.

Fortunatly, it's not hard to do, you can do it yourself by replace one line: 136 to sub codes:

    //========= begin replace origin line 136 for rotate
    var x = pos[0] - lloc[0];
    var y = pos[1] - lloc[1];
    var rotate = options.rotate || 0;
    var angle = (rotate / 90) % 4;
    if (angle == 1) {
      var temp = x;
      x = y;
      y = - temp;
    } else if (angle == 2) {
      x = -x;
      y = -y;
    } else if (angle == 3) {
      var temp = x;
      x = -y;
      y = temp;
    }
    Coords.moveOffset([x, y]);
    //========= end replace origin line 136 for rotate

or you can get the updated code by url: https://github.com/ergoli/Jcrop/tree/master/js

be careful! you should transfer the rotate option after each rotate click:

jCropApi.setoptions({rotate : 90});  //rotate 90

good luck!
