Copy images from a SortedList to another SortedList

fsup

For the whole process I use multichannel images (Zeiss *.czi's). Certain channels are extracted and for further processing stored in a SortedList (named origImageList).

On the extracted channels various filters are applied and finally the number of objects is determined. Also modified channels are stored in a SortedList (named modImageList). During the process the modImageList is cleared and the origImageList should copied to the modImageList to start a new process.

The problem is that lists only store references and not values. I tried out different "DeepCopy" solutions like serialization without any success.  Look at the simple APP.

How can I transfer contents of a SortedList to another SortedList without a reference?

Thanks in advance

Hi fsup,

I checked your project. All your collections contain references to images. If you want to keep 2 different collections, one original and another modified, you should create copies of these images using Duplicate function, like that:

        ' transfer to modImageList and apply for example lowpass filter
        For Each kvp In origImageList
            newInt = kvp.Key
            newIm = DirectCast(kvp.Value, McImage)
            newIm =newIm.Duplicate(mcImageCreateFlags.mcicfNotVisible Or mcImageCreateFlags.mcicfNoAddToCollection)
            LowPassFilterProcessing(newIm, 500, 1)

            modImageList.Add(newInt, newIm)
        Next

Please let me know if that's what you wanted.
