如何在目标C中将NSImage转换为NSMutable数组？

Question

我有一个NSImage，需要将其转换为相同大小的NSMutable数组。

我最初将NSMutableArray转换为NSImage，调整大小，转换为CVPixelBuffer，然后输入coreML模型。

NSSize newSize;
newSize.height = 512;
newSize.width = 512;

const NSImage* segImage = [Viewer1.imageView nsimage:YES];
[segImage setScalesWhenResized:YES]; //'setScalesWhenResized:' is deprecated: first deprecated in macOS 10.6

NSImage *resized = [[NSImage alloc] initWithSize: newSize];
[resized lockFocus];
[segImage setSize: newSize];
[[NSGraphicsContext currentContext] setImageInterpolation: NSImageInterpolationHigh];
[segImage drawAtPoint:NSZeroPoint fromRect:CGRectMake(0, 0, newSize.width, newSize.height) operation:NSCompositeCopy fraction:1.0];
[resized unlockFocus];

该模型生成了一个CVPixelBuffer，我将其转换为CGImageRef，然后转换为NSImage并对其进行了调整大小（也许可以用一种不太复杂的方式来完成所有这些工作？）。

//Convert to NSImage and Resize
NSSize oldSize;
oldSize.height = pixHeight;
oldSize.width = pixWidth;

//const NSImage* segImage2 = [Viewer1.imageView nsimage:YES];
[newImage setScalesWhenResized:YES]; //'setScalesWhenResized:' is deprecated: first deprecated in macOS 10.6

NSImage *ROImask = [[NSImage alloc] initWithSize: oldSize];
[ROImask lockFocus];
[newImage setSize: oldSize];
[[NSGraphicsContext currentContext] setImageInterpolation: NSImageInterpolationHigh];
[newImage drawAtPoint:NSZeroPoint fromRect:CGRectMake(0, 0, oldSize.width, oldSize.height) operation:NSCompositeCopy fraction:1.0];
[ROImask unlockFocus];

现在，我只需要绕个圈，然后将NSImage转换回NSMutableArray。在Objective C中如何完成？
