_error not defined

[sebastianpech]

There's a function _error used in src/CosReader.jl that is undefined.

Can you upload the file where you observed this behavior? Although the fix may be easy, for a test case to be added we need to have the file.

[sebastianpech]

No I can't, but I will check if I can extract the part thats causing the error

[sambitdash]

@sebastianpech I guess #80 should fix this. But, I will keep the issue open just so that you can provide us an isolated extracted file to add to the test case.

This is the error I get:

Do you have any tipps for debugging that. My problem is that the error occurs in a pdf generated not on my device. After removing a page, undo to add it back and then save on my device the error vanishes.

[sebastianpech]

Apparently it's a space (0x20) that's causing the problem

[sambitdash]

@sebastianpech the _error was a bug in the library which has been fixed.

For the specific error reported in your file now, I will have to review the file to comment. If you are ok, you can share the file with me over email as well. It will be hard to comment from the trace you sent. The issue seems to be in a font file embedded inside the PDF file.

[sambitdash]

9ceafda may fix the issue as reported if I go by your comment on the space character.

@sebastianpech Please take the latest build and try out.

[sebastianpech]

@sebastianpech the _error was a bug in the library which has been fixed.

Yeah I know. But I'm curious what's causing the error.

Sadly I really can't send you the file, it contains personal data from students and I can't get the data out as the moment I change something the error is gone.

9ceafda may fix the issue as reported if I go by your comment on the space character.

Currently building

That did the trick thanks.

I have another pdf which fails at this

PDFIO.jl/src/PDPageElement.jl

Line 618 in eeff74c

@assert w > 0.1f0

assertation. Could that be related to objects being larger than the pagewidth?

Please file a separate bug on this.

Closing this bug based on the comment above.
