40475a3093 Clean unneeded stuff separating the monadic type constraint from the actual monad stack used, one more step towrds MonadFail -> MonadError 2020-03-14 16:55:34 +01:00
b6c1f670ef Generalize the search for FlateDecode (there can be several filters in an array) 2020-03-11 10:47:52 +01:00
dce10ae63a Keep Page as only a reference object keeping the ObjectId explicit so we can modify the actual objects one day, write an OrderedMap data structure to help 2020-03-08 22:18:47 +01:00
2b9abc24b6 Add a separate instance for Raw streams that don't try to decode them 2020-03-04 18:31:30 +01:00
7cef65d799 Fixed vicious bug introduced by 6096a1a237 (since follow is now automatic for references, it's not called explicitely but should in case of 'several' Content, which is an array of references, each of which should be expended) — TODO: add a unit test for that 2020-03-04 18:14:33 +01:00
2c02e44adf Export the PDFContent monadic type used in PDF.Pages 2020-03-03 18:16:12 +01:00
4969c6442e Simple String aliasing to prepare the day when we'll be able to have more complex Component than just PDF Names (and access elements in an array) 2020-02-28 18:14:27 +01:00
99014ff30d Recognize openStream was just an implementation of r for the Box m () Object ByteString, and extend it implementing the w operation while we're at it 2020-02-26 22:13:29 +01:00
36b1782464 Follow previous renaming for a local variable in Navigation for more clarity 2020-02-23 22:15:52 +01:00
bcf2e05bfb Move Content out of Object module into a separate one incorporating PDF.Update (which is actually an operation that is defined only on that structure), and rename it Layer to avoid confusion with Content streams as defined in the specs (which have their own PDF.Content module already) 2020-02-17 15:29:59 +01:00
6096a1a237 Simplify navigations by centering everything on Objects to avoid needing to many conversion tools between DirectObject / Object / Dictionary 2020-02-15 13:51:24 +01:00
23186100a8 Reimplement getObj with the newest tools in PDF.Object.Navigation, in particular implement browsing by paths or random objectId access 2020-02-15 10:25:09 +01:00
b916ab5206 Just noticed Streams are a kind of Dictionary too, since they have a header 2020-02-15 10:23:32 +01:00
4a6dbda7d3 Move Error type from Pages to Navigation as a candidate for MonadFail required by PDFContent defined there 2020-02-15 10:22:42 +01:00
eb4d76002c Finish the split of Navigation out of Page, generalize the use of MonadFail with a custom Error monad (~= Either String) 2020-02-11 22:41:46 +01:00
704d7a7fcf It turns out Output.concat wasn't necessary, OBuilder seems already is a Monoid so mconcat works (that fact was used in the very implementation of concat…) 2020-02-11 17:36:29 +01:00
aed7af376a WIP: still trying to figure things out, moved to a separate submodule for Navigation, proper naming is hell 2020-02-11 08:29:08 +01:00
