从CGBitmapContextGetData返回的void*是什么？-Whatisthevoid*returnedfromCGBitmapContextGetData?

I'm trying to get the pixel information from an image and have got to the point where I have my void* data object which is a pointer to the image data.

我正在尝试从图像中获取像素信息,并且已经达到了我的void * data对象的位置,该对象是指向图像数据的指针。

What exactly is this object? I've tried iterating over it hoping that it's an array of pixel info but it doesn't seem to work.

这个对象究竟是什么?我试过迭代它希望它是一个像素信息数组但它似乎不起作用。

I want to get the rgb values for each pixel.

我想获得每个像素的rgb值。
