Hello ! every one.

I am having a little query regarding CFData in Objective C / iPhone Development.

See, Apple documentation has following method for CGPDFStream

CGPDFStreamCopyData(<#CGPDFStreamRef stream#>, <#CGPDFDataFormat *format#>)

Above method return type is CGDataRef. I have data as stream. Now I wish to convert in image. & For that I think I should follow this way.

CGPDFDataFormat t=CGPDFDataFormatJPEG2000;
CFDataRef data = CGPDFStreamCopyData (stream, &t);

After executing above statements - I have some reference in data variable.

Now my Query is - How to convert this CFData to NSData or UIImage ?

I have gone through the documentation of apple - But I am failure to find it.

Thanks in advance for sharing your knowledge.
