Hi, list! When I try to convert a PDF generated by ConTeXt LMTX to PNG using ImageMagick's convert the following happens:

I'd blame ImageMagick, except for the fact that 1) other converters fail too and 2) it doesn't happen with ConTeXt MkIV (PDF is successfully converted).

Cordially,

Very interesting! I have seen similar behavior these past days (I think it's very recent) but thought it was something in my documents. Hans, MWE: I have two test files, simply with \starttext Test \stoptext I try to concatenate the resulting pdf files with qpdf: qpdf test1.pdf --pages test1.pdf test2.pdf -- result.pdf And I get these warnings (though the resulting file appears to be OK): WARNING: test1.pdf (xref stream: object 18 0, offset 4154): expected endstream WARNING: test1.pdf (xref stream: object 18 0, offset 4078): attempting to recover stream length WARNING: test1.pdf (xref stream: object 18 0, offset 4078): recovered stream length: 64 WARNING: test1.pdf (object 3 0, offset 4179): expected endstream WARNING: test1.pdf (object 3 0, offset 2982): attempting to recover stream length WARNING: test1.pdf (object 3 0, offset 2982): recovered stream length: 887 WARNING: test2.pdf (xref stream: object 18 0, offset 4215): expected endstream WARNING: test2.pdf (xref stream: object 18 0, offset 4139): attempting to recover stream length WARNING: test2.pdf (xref stream: object 18 0, offset 4139): recovered stream length: 65 WARNING: test2.pdf (object 3 0, offset 4241): expected endstream WARNING: test2.pdf (object 3 0, offset 3050): attempting to recover stream length WARNING: test2.pdf (object 3 0, offset 3050): recovered stream length: 880 qpdf: operation succeeded with warnings; resulting file may have some problems
