I'd like to obtain an RGB array from an image so that I can manipulate the array of pixels, and then draw the modified image on a canvas. UPDATE: I found an exact duplicate here: how to get the RGB value of an image in a page using javascript? However, the answers don't go int...

创建CGImage 時需要提供详细的配置参数,其中部分参数和创建 CGBitmapContext 相同,额外需要提供的就是默认参数以及不需要使用的特性比如 decode array 等等。得到 CGImageRef 后可以直接得到 UIImage 对象,但是我发现我的同事写了如下一段代码: UIGraphicsBeginImageContext(outSize);// the same: UIGraphicsBeginImageCon...
