returns a reference to the added image object when calling addjpeg so that it can be shared between or within pages meaning the image is only written to the output file once but can appear multiple times.
this image doesn't seem to be displaying correctly in adobe reader.
since jpegs can be trivially embedded in pdf documents without changes to the data stream this is the first image format we will support. currently this is a naive approach which doesn't share an image resources between pages. ideally we will either de-duplicated images when added, return a re-usable key once an image is added, or both.
Anyway, the DataToken properties most are readonly, If you want to change something. You have to crate a new token anyway. Discussion: https://github.com/UglyToad/PdfPig/pull/150
This class would allow us to lazily flush resource. This would allow us to make changes to them, while new content is pushed. Compress, Merge, Deduplicate, etc...
it is possible for a file with an adobe type 1 font to contain an invalid charstring sequence, if this happens we handle it and return false from trygenerate.
after we split the solution into multiple projects the xml doc comments were no longer packed in the generated nuget package. in addition they were only generated for the net standard 2.0 target framework.
this change generates comments for all target frameworks and makes sure they're included in the generated package. it also adds missing doc comments where they weren't included on the public api and clears up a couple of minor formatting issues in the affected files.
fixes the case where the brute-force searcher becomes stuck in an infinite loop, it may be the case that the problem pdf from #88 has a newline or some other whitespace between its object and generation number so this may cause a failure elsewhere.
most of the cross-reference code is the earliest code in the project and hasn't been revisited since then. the issue #88 has been reopened due to a bug with brute-force searching so this tidies up the code in this area ahead of trying to fix the bug.
check that we correctly handle the case where a comment appears inside a dictionary, this was handled by commit 3084a9. use list internally to dictionary tokenizer to avoid interface performance penalties.
renames fields to match the expected conventions for resharper. removes fully qualified names for using statements since resharper marks these as not-required.
adds a check to the pdf merger test to make sure the second page has the expected content. this is not currently valid since we lose the resources node on the pages tree.
the cross reference parser tests behaviour had change, this fixes a compilation error from merge conflicts. also updates the merger tests to account for new version behaviour and checks the output document text. adds pdfmerger to the public api in the tests.
I decided to move to his own method, the part that create the page node. This allowed me to visualize better, from where I was suppose to get the correct reference.
