我正在開發平均堆棧應用程序。
我被困在照片編輯器中。
我使用「Camanjs」爲照片效果並在angularjs 1編輯它。 它將適用於滑塊的第一個圖像,但如果我編輯第一個圖像後選擇任何其他圖像形式滑塊,然後它顯示舊圖像。如何在動態圖像的camanJs畫布中發揮作用?
我的文件(在angularjs指令)
.directive('hzPhotoEditor', ['$timeout', function($timeout) {

console.log("fill canvas called");
console.log(data.photo);
scope.fillCanvas(data);

- >如果我的評論 「this.revert(假);」行並取消註釋「this.reloadCanvasData();」線形式「scope.applyImageParameters」函數,然後它工作得很好,但它不會在色相0,對比度0等工作。
- >如果我評論「this.reloadCanvasData();」並取消註釋「this.revert(false);」線形式「scope.applyImageParameters」功能,然後效果作品很好,但它顯示舊圖像不是當前圖像有效
圖像附加兩個屏幕排序的更多細節。
First edited image after giving effect
Second image after giving effect
任何機構可以幫我解決這個問題?
