if (width && height) {     if (min_width < width || min_height < height) {         image.setsize(width, height);     } else {         group.children[1].hide();         group.children[2].hide();         group.children[3].hide();         group.children[4].hide();         $(".tosmall").dialog({             modal: true,             width: 350,             height: 180,             buttons: {                 "ok": function() {                     $(this).dialog("close");                     image.setsize(image.width, image.height);                     console.log(activeanchor.attrs.draggable = false);                     activeanchor.attrs.x *= 2;                     activeanchor.attrs.y *= 2;                     image.off('click');                     // activeanchor.setdragontop(false);                     // activestage.draw();                 }             }         });     } }

i found own solution 

if (width && height) {     if (min_width < width || min_height < height) {         image.setsize(width, height);     } else {         $(".tosmall").dialog({             modal: true,             width: 350,             height: 180,             buttons: {                 "ok": function() {                     activeanchor.hide();                     activeanchor.attrs.y *= 2;                     image.off('click');                     $(this).dialog("close");                     update(activeanchor);                     activestage.draw();                 }             }         });     } }
