Run texlua with this code:
local doc = pdfe.open('test.pdf')
local page = pdfe.getpage(doc, 1)
local stream = page['Contents']
pdfe.openstream(stream)
local str, n = pdfe.readfromstream(stream)
print(str)
print(n)
Here test.pdf is:
\pdfvariable compresslevel = 0
\pdfvariable objcompresslevel = 0
Lorem ipsum dolor sit amet
... a lot more text here ...
\bye
Not matter how long the stream is, pdfe.readfromstream() always returns the
whole stream.
What's the difference to pdfe.readwholestream()?
