macOS How to convert bitmap data to TIFF?

[revg]

Hi,

I am using Carbon for my lanaguage and I am unable to use Cocoa. Does anyone know how I can convert the bitmap data returned as shown below to a TIFF format in a CFDataRef variable?

void *data = CGBitmapContextGetData (cgctx);
//how can I now take the bitmap data from the variable data
//and convert it to a CFDataRef in a TIFF format?

Thanks

Here is the solution

void copyCGImageRefToPasteboard(CGImageRef ref)
{
	OSStatus err = noErr; 
	PasteboardRef theClipboard; 
		
	err = PasteboardCreate( kPasteboardClipboard, &theClipboard ); 
	err = PasteboardClear( theClipboard );// 1 
		
	CFMutableDataRef url = CFDataCreateMutable(kCFAllocatorDefault, 0);
		
	CFStringRef type = kUTTypeTIFF;
	size_t count = 1; 
	CFDictionaryRef options = NULL;
	CGImageDestinationRef dest = CGImageDestinationCreateWithData(url, type, count, options);
	CGImageDestinationAddImage(dest, ref, NULL);
	CGImageDestinationFinalize(dest);

	err = PasteboardPutItemFlavor( theClipboard, (PasteboardItemID)1, type, url, 0 ); 
}
