Error Converting Int to UInt about pdf-class-raku

[dwarring]

pdf-checker is complaining because it's expecting a UInt (non-negative integer) for /StructParent entries, but the above example it's getting a negative value -167.

I rechecked Annotations (table 164 in the spec). I think the error is valid. These values are an array index and shouldn't be negative.

Although pdf-checker being a bit spammy and reporting multiple warnings, before it finds the error.

Where are the errors coming from in the first place?

The pdf-append script produces this warning, if I add a negative /StructParent to a PDF Annotation. It probably shouldn't.

Warning is useless anyway, it doesn't indicate where in the PDF the problem is.

@tsalada - I've removed those warnings. They were being produced while the PDF objects were being copied.

pdf-checker (as you've already noticed) can be used to find an errors in the input PDF anyway.

Please upgrade to the latest PDF 0.5.4, which I've just uploaded to the zef ecosystem. This release suppresses those warnings.

This worked. I was able to extract the pages I needed. Thanks.
