I could upload it in some place but you don't need it, really. The
specification is clear, the length of a data chunk must be less
than 2^31 - 1, and the complete image data is represented by a
single zlib datastream that is stored in "some" number of IDAT
chunks. That's all. A decoder can't make any other assumptions
about the size or the boundaries of the chunks, of course correct
me if I'm wrong.
Anyway if you are curious they were music scores extracted from a
pdf using mutool (mupdf).
