2014-04-01Solve crash (NullPointerException) when cancelling from password promptRobin Watts
Attempt to open a file that needs a password, and you will get a dialogue box. Hit cancel on this, and the program crashes. This is due to an attempt to release the bitmaps on a document view that does not exist. Simple fix.
2014-04-01Fix Android build w.r.t. mujs.Robin Watts
The get_globals helper function only works on non-class objects. Hence 'MuPDFCore_javascriptSupported' can't be a static function.
2014-04-01Various android fixes.Tor Andersson
Update Android build to cope with new stream implementation. Fix a couple of typos in the android build files.
2014-03-26iOS: fix build and update to use mujsPaul Gardiner
2014-03-26Pull mujs source into VS solution (disabled)Robin Watts
This enables us to search the source easily, without affecting the fact that it is compiled using one.c in a single block.
2014-03-25Update the winrt solution with the changes made in the win32 solution.Michael Vrhel
Also update the code for the changes made in the stream API
2014-03-25Use MuJS in Android build.Tor Andersson
2014-03-25Update win32 project files for JS.Tor Andersson
2014-03-25Break dependencies on pdf-form.c and pdf-js.cTor Andersson
Split functions out of pdf-form.c that shouldn't be there, and make javascript initialization explicit.
2014-03-25Break dependency of pdf-annot.c to graphics library.Tor Andersson
2014-03-19Add routine to clean pdf content streams for pages.Robin Watts
New routine to filter the content streams for pages, xobjects, type3 charprocs, patterns etc. The filtered streams are guaranteed to be properly matched with q/Q's, and to not have changed the top level ctm. Additionally we remove (some) repeated settings of colors etc. This filtering can be extended to be smarter later. The idea of this is to both repair after editing, and to leave the streams in a form that can be easily appended to. This is preparatory to work on Bates numbering and Watermarking. Currently the streams produced are uncompressed.
2014-03-19Implement our own vsnprintf variant.Tor Andersson
The primary motivator for this is so that we can print floating point values and get the full accuracy out, without having to print 1.5 as 1.5000000, and without getting 23e24 etc. We only support %c, %f, %d, %o, %x and %s currently. We only support the zero padding qualifier, for integers. We do support some extensions: %C turns values >=128 into UTF-8. %M prints a fz_matrix. %R prints a fz_rect. %P prints a fz_point. We also implement a fprintf variant on top of this to allow for consistent results when using fz_output. a
2014-03-18Fix operator buffering of inline images.Robin Watts
Previously pdf_process buffer did not understand inline images. In order to make this work without needlessly duplicating complex code from within pdf-op-run, the parsing of inline images has been moved to happen in pdf-interpret.c. When the op_table entry for BI is called it now expects the inline image to be in csi->img and the dictionary object to be in csi->obj. To make this work, we have had to improve the handling of inline images in general. While non-inline images have been loaded and held in memory in their compressed form and only decoded when required, until now we have always loaded and decoded inline images immediately. This has been due to the difficulty in knowing how many bytes of data to read from the stream - we know the length of the stream once uncompressed, but relating this to the compressed length is hard. To cure this we introduce a new type of filter stream, a 'leecher'. We insert a leecher stream before we build the filters required to decode the image. We then read and discard the appropriate number of uncompressed bytes from the filters. This pulls the compressed data through the leecher stream, which stores it in an fz_buffer. Thus images are now always held in their compressed forms in memory. The pdf-op-run implementation is now trivial. The only real complexity in the pdf-op-buffer implementation is the need to ensure that the /Filter entry in the dictionary object matches the exact point at which we backstopped the decompression.
2014-03-17Rework fz_streams.Robin Watts
Currently fz_streams have a 4K buffer within their header. The call to read from a stream fills this buffer, resulting in more data being pulled from any underlying stream than we might like. This causes problems with the forthcoming 'leech' filter. Here we simplify the fields available in the public stream header. No specific buffer is given; simply the read and write pointers. The underlying 'read' function is replaced by a 'next' function that makes the next block of data available and returns the first character of it (or EOF). A caller to the 'next' function should supply the maximum number of bytes that it knows it will need (possibly not now, but eventually). This enables the underlying stream to efficiently decode just enough. The underlying stream is free to return fewer, or a greater number if it wants to. The exact size of the 'block' of data returned will depend on the filter in use and (possibly) the data therein. Callers can get the currently available amount of data by calling fz_available (but again should pass the maximum amount of data they know they will need). The only time this will ever return 0 is if we have hit EOF.
2014-03-04Bug 691691: Add way of clearing cached objects out of the xref.Robin Watts
We add various facilities here, intended to allow us to efficiently minimise the memory we use for holding cached pdf objects. Firstly, we add the ability to 'mark' all the currently loaded objects. Next we add the ability to 'clear the xref' - to drop all the currently loaded objects that have no other references except the ones held by the xref table itself. Finally, we add the ability to 'clear the xref to the last mark' - to drop all the currently loaded objects that have been created since the last 'mark' operation and have no other references except the ones held by the xref table. We expose this to the user by adding a new device hint 'FZ_NO_CACHE'. If set on the device, then the PDF interpreter will pdf_mark_xref before starting and pdf_clear_xref_to_mark afterwards. Thus no additional objects will be retained in memory after a given page is run, unless someone else picks them up and takes a reference to them as part of the run. We amend our simple example app to set this device hint when loading pages as part of a search.
2014-03-04Add pdf_process for filtering operator streams.Robin Watts
Currently this knows about q/Q matching/eliding and avoiding repeated/unneccesary color/colorspace setting. It will also collect a dictionary of resources used by a page. This can be extended to be cleverer in future.
2014-03-04Add pdf_process for writing operator streams out to a buffer.Robin Watts
Using this, we can reconstruct pdf streams out of the process called. This will enable us to do filtering when used in combination with future commits.
2014-03-04Add pdf_process interface.Robin Watts
Currently the only processing we can do of PDF pages is to run them through an fz_device. We introduce new "pdf_process" functionality here to enable us to do more things. We define a pdf_processor structure with a set of function pointers in, one per PDF operator, together with functions for processing xobjects etc. The guts of pdf_run_page_contents and pdf_run_annot operations are then extracted to give pdf_process_page_contents and pdf_process_annot, and the originals implemented in terms of these. This commit contains just one instance of a pdf_processor, namely the "run" processor, which contains the original code refactored. The graphical state (and device pointer) is now part of private data to the run operator set, rather than being in pdf_csi.
2014-02-10Bug 695022: Add TIFF format handlerRobin Watts
Patch from Thomas Fach-Pedersen. Many thanks! Add a new format handler that copes with TIFF files. This replaces the TIFF functionality within the image format handler, and is better because this copes with multiple images (as one image per page).
2014-01-27Android: fix to account for document handlersPaul Gardiner
2014-01-20iOS: fix the release buildPaul Gardiner
Change the library copying to use a system variable for the location that works in both builds

2014-01-15Remove repeated NDEBUG in release preprocessor list in WinRT projectsMichael Vrhel
2014-01-15Clearer division in WinRT vs std C++ codeMichael Vrhel
To share as much code as possible between the Windows 8 app, windows phone app and Windows desktop app, remove dependencies of Platform and Windows::Foundation in files that interface to mupdf and replace with C/C++ std methods.
2014-01-15Minor changes for windows 8 store validationMichael Vrhel
2014-01-15Fixes for Windows 8.1 store validationMichael Vrhel
We have to clean up the DirectX memory during suspension. Also define NDEBUG for the release cases so that we avoid the use of OutputDebugStringA in error.c which is not allowed in Windows store apps.
2014-01-13iOS: attach the slider to the toolbar differently for iOS 7Paul Gardiner
Under iOS 7, the slider becomes inoperable when included a toolbar item in the standard way. Instead just add it as a subview, being careful to also remove it to avoid multiple copies
2014-01-10iOS: animate the custom buttons used for the iPhone buildPaul Gardiner
2014-01-10iOS: correctly handle document changes that may affect several pagesPaul Gardiner
Interaction with forms may change several pages, so all pages currently represented by view need updating.
2014-01-10iOS: better structure the page update codePaul Gardiner
2014-01-10iOS: on iPhone use custom buttons to accommodate shortage of spacePaul Gardiner
Otherwise, in portrait mode, there isn’t enough room for all five buttons and some are not displayed.
2014-01-09Add tiling into the DirectX printing code.Michael Vrhel
The tiling in x and y is needed to ensure that we can print at high resolutions with devices that have smaller bit map sizes (e.g. the surface). Banding only in the y dimension like we often do is not sufficient. Also fix an open with file association bug that must of occurred with the transition to 8.1 And update WinRT solution for recent changes in mupdf code. This includes the addition of a few new files and the document type registration.

2014-01-09Update copyright date.Tor Andersson
2014-01-09iOS: save changes on returning to the libraryPaul Gardiner
Also change the way the back button works, using an explicit action, rather than relying on the navigation controller. Doing so allowed an alert dialog to be displayed asking if document changes should be discarded or saved. It also allowed the word-based button to be replaced by an icon-based one, which saves space (important for iPod and iPhone). We may want to also save on other occasions, but this at least provides some way to do so.
2014-01-07iOS: remove search-bar-transparency hackPaul Gardiner
Doesn’t work in iOS 7.1: removes the the whole text view
2014-01-07iOS: don’t allow hiding of the navigation bar when it is other than at the ↵Paul Gardiner
root menu Seems more natural and avoids cases where tapping doesn’t bring the bar back, hence trapping the user in one of the submodes.
2014-01-07iOS: protect against crashing when handling accented chars in choice fieldsPaul Gardiner
Use conversion assuming ascii as a fallback to assuming utf8. The library should be converting to utf8 but doesn’t currently.
2014-01-07iOS: update the form filling dialogs to avoid the keyboard hiding the buttonsPaul Gardiner
Also bring up the keyboard automatically
2014-01-07iOS: fix for document handlersPaul Gardiner
2014-01-07Introduce 'document handlers'.Robin Watts
We define a document handler for each file type (2 in the case of PDF, one to handle files with the ability to 'run' them, and one without). We then register these handlers with the context at startup, and then call fz_open_document... as usual. This enables people to select the document types they want at will (and even to extend the library with more document types should they wish).
