objective-c - 从 cocoa Mac App创建的JPEG中嵌入颜色配置文件sRGB

我在可可Mac应用程序中使用以下代码创建JPEG。如何将srgb颜色配置文件嵌入到创建的JPEG中？

NSImage* savedImage = [[NSImage alloc] initWithSize:NSMakeSize(600, 600)];
[savedImage lockFocus];
//draw here
[savedImage unlockFocus];

NSBitmapImageRep* savedImageBitmapRep = [NSBitmapImageRep imageRepWithData:[savedImage TIFFRepresentationUsingCompression:NSTIFFCompressionNone factor:1.0]];

NSDictionary* properties = [NSDictionary dictionaryWithObjectsAndKeys:
                            [NSNumber numberWithFloat:1.0], kCGImageDestinationLossyCompressionQuality,
                            nil];

NSMutableData* imageData = [NSMutableData data];
CGImageDestinationRef imageDest =  CGImageDestinationCreateWithData((CFMutableDataRef) imageData, kUTTypeJPEG, 1, NULL);
CGImageDestinationAddImage(imageDest, [savedImageBitmapRep CGImage], (CFDictionaryRef) properties);
CGImageDestinationFinalize(imageDest);

// Do something with imageData
if (![imageData writeToFile:[@"~/Desktop/test.jpg" stringByExpandingTildeInPath] atomically:NO])
    NSLog(@"Failed to write imageData");

最佳答案

不知道如何使用这些高级API来执行此操作。我自己通过将所需的IFD添加到JPEG数据中来完成此操作。
