Yes, you most likely right. 
I did some preliminary hacking and got it to partly work, but I don't know the real issues the image segment loading and converting entails.

But there are some conversion issues I have not figured out.

Looking at this change:

ObjectScanner>>scanFrom: aByteStream
"Sieze control of the fileIn.  Put myself in as the context.  If any UniClasses (for just one instance) are defined, they will do it through me, and I will look for conflicting class names.  If so, install the old name as a class var of me, so the compile will work.  Tell my SmartRefStream about renaming the class."

| valWithOddName47 scannerNamed53 chunkNamed117 |
pvt3SmartRefStrm := SmartRefStream on: aByteStream.
aByteStream ascii.
[aByteStream atEnd] whileFalse:
[aByteStream skipSeparators.
valWithOddName47 := (aByteStream peekFor: $!)
ifTrue: [chunkNamed117 := aByteStream nextChunk. "debug"
chunkNamed117 = 'ImageSegment new' 
ifTrue:[ chunkNamed117 := 'NativeImageSegment new'].
scannerNamed53 := Compiler evaluate: chunkNamed117
for: self logged: false.
scannerNamed53 class == self class 
ifTrue: ["I already am the scanner for this file"]
ifFalse: [scannerNamed53 scanFrom: aByteStream]]
ifFalse: [chunkNamed117 := aByteStream nextChunk.
chunkNamed117 := self lookAhead: chunkNamed117.
Compiler evaluate: chunkNamed117 for: self logged: true].
aByteStream skipStyleChunk].
^ valWithOddName47
 

you introduced the lines:

chunkNamed117 = 'ImageSegment new' 
ifTrue:[ chunkNamed117 := 'NativeImageSegment new'].

I think this is not going to work.  The issue being at this point we won't know whether we have a legacy image segment or a native image segment.  If you look at the hierarchy, there is
    ImageSegment
        NativeImageSegment
        LegacyImageSegment
and intentionally all the list vars are in ImageSegment so that when the scan of the actual binary data, embedded in the .pr file occurs, we can use something like (legacy ifTrue: [LegacyImageSegment] ifFalse: [NativeImageSegment]) adoptInstance: themageSegment to become the right kind of image segment.  So the way to proceed is to make ImageSegment intelligent enough to get you as far as the point where the kind of image segment, V3 or Spur, is apparent, and then make the switch.

HTH
 

NOTE: Image will probably crash. USE WITH CARE

Karl
