Not at the same time on the same file. #put:into is use in one situation to write out a sketch as a XML file, and in another situation to write out a PNG image. However, It is true DrGeo xml document can embed bitmap, but it is base64 encoded, so saving with readStream is not a problem. I am still curious how I will use wrappedStream in case DrGeo's XML document contained binary data. Le 26/07/2019 à 08:03, Sven Van Caekenberghe a écrit :
You said you wanted to write both character data (XML) as binary data (images) to the same stream, or so I understood.

I don't understand how #wrappedStream works in my situation?
Is #isBinary not good enougth?

If you have a character read or write stream, you can use #wrappedStream to access the underlying binary stream, should you need to do that.

Thanks for the tips. It is definitely a left over from porting DrGeo to P7 from P4/5/6 (not sure)
But it can't really work as put:into: is used to write both sktech content (XML file) and its PNG preview.
At some point in Pharo history both UTF8 and bitmap were using binary stream.
Likely a putBinary:into: is needed too.
