我可以使用jquery實現捕捉網格操作與KineticJS 中的圖像嗎? (http://jqueryui.com/demos/draggable/snap-to.html) 就像我在畫布中有很少可拖動的圖像,並且我希望它們限制畫布內部的移動...使用圖像對齊網格操作,kinetic.js,javascript?
當畫布中的某個靠近另一個時,是否有可能將2個圖像拼接在一起?? 而且可以在使用kinetic.js或JavaScript來實現......
感謝 阿希什
這裏是代碼.. 這是一個有點複雜。我的意思是,我從外面canvas..and加載圖像有兩種sets..now我想要一套能夠捕捉到其他..
