I do not see any issues with the specific file. Please send the specific file where you are seeing the issues. file.txt

jakewilliami commented 4 years ago

That is the specific file I am using. I am using OS X 10.14.

Which version of Julia and PDFIO you are using. May be you are on older versions.

I think you are seeing behavior as seen in: #72 which has been fixed in v0.1.8.

jakewilliami commented 4 years ago

I am using Julia version 1.4.1, and PDFIO version 0.1.7, so you are right (sorry, I didn't actually see #72 before posting this issue). However, I used Pkg.add("PDFIO") a day before posting this issue. Why did Pkg install version 0.1.7 if this is an old version?

jakewilliami commented 4 years ago

It's because I didn't actually update the registry...I only thought it was updated (because I thought that's what it does every time I run using Pkg...

Needed to update

]update

Then check if I can install the latest version with

]add PDFIO@v0.1.9

Thank you for your help and patience!
