Hi, all. I am working on creating a PDF with Artefact (https://github.com/pharo-contributions/Artefact) and am having an issue running the first example. the Example looks like: PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream. When running this, I get the error: Instance of ByteArray did not understand #isByteString indeed, ByteArray does not have a method called isByteString. I have tried creating a method that returns either true or false (I tried them both), but I have not successfully built the PDF. The method calling isByteString looks like: ZnUTF8Encoder next: count putAll: string startingAt: offset toStream: stream "Write count characters from string starting at offset to stream." "Overwritten for performance reasons - create a fast path for byte strings" string isByteString ifTrue: [ self next: count putAllByteString: string startingAt: offset toStream: stream ] ifFalse: [ super next: count putAll: string startingAt: offset toStream: stream ] I TOTALLY get this. This is a whole bunch of very specific questions. But my ultimate goal is to take a deep dive into stream processing to figure this out.
