2018-07-04Rename pdf_get_annot_contents to pdf_annot_contents.Tor Andersson
Since the function no longer returns ownership of the string, use the common naming convention.
2018-07-04Add fz_is_point_inside_rect utility function.Tor Andersson
2018-07-04Allow for CIDToGIDMap in font being "/Identity".Robin Watts
Previously we would have tripped over this, thrown an error and aborted loading the whole page. Any non-stream, non "Identity" CIDToGIDMaps now produce a warning rather than an error so we don't stop processing the entire page.
2018-06-22Update base 14 fonts to URW++ release from 2017-07-27.Tor Andersson
The Dingbats and Symbol fonts have not been changed.

2018-06-22Don't pollute namespace with our 'restrict' macro. Use FZ_RESTRICT instead.Tor Andersson

2018-06-22Keep copy of decoded utf8 text string in pdf_obj.Tor Andersson
Removes the need to alloc/free text strings in the API, allowing for simple functions like pdf_dict_get_text_string.
2018-06-22Look up DA in Root/AcroForm/DA if missing in annotation property.Tor Andersson
2018-06-22Merge pdf-annot.c and pdf-annot-edit.c (2/2).Tor Andersson

2018-06-22Move link code to pdf-link.c.Tor Andersson
2018-06-22Fix error check in AFPercent_Format to look for null rather than false.Tor Andersson
The number 0 is a valid percentage number.
2018-06-22Call AA/F formatting when synthesizing appearance stream.Tor Andersson
2018-06-22Use line spacing and padding when creating variable text appearance.Tor Andersson
Format single-line Widget/Tx fields vertically centered.
2018-06-22Support annot/MK/R property in Tx and Ch widget annotations.Tor Andersson
2018-06-22Support undocumented annot/Rotate property in FreeText annotations.Tor Andersson
2018-06-22Remove rich text properties when editing annotation contents or styles.Tor Andersson
We do not support rich text content; remove the properties rather than leave them untouched and out of sync with the simple contents and styles.
2018-06-22Use /Tx BMC ... EMC when creating text widget appearance streams.Tor Andersson
2018-06-22Support rotated QuadPoints when generating markup annotation appearances.Tor Andersson
2018-06-22Create appearance streams for annotations.Tor Andersson
Now handles more annotation types, and does not use the pdf-write device. Handles many of the usual annotation properties, such as border width, color, interior color, line ending styles. * Ink * Highlight, Underline, Strike-Out, Squiggly * Line (with arrow-heads) * Polygon * PolyLine * Square * Circle * Caret * Text (needs better icons) * FileAttachment (needs better icons) * Sound (needs better icons) * Stamp * FreeText Partially complete: * Widget (treats everything like a plain text field) Not done, but on the to-do list: * /BS style (solid/dashed/bevel/inset/underline) * /BS dash pattern Not done and not on the list: * Movie * Screen * Printer's Mark * Trap Network * Watermark * /Border corner radii (ignored by acrobat) * /BE cloudy border effect
2018-06-22Remember the md5 digest in the fz_font struct.Tor Andersson
2018-06-22Cache base14 and CJK fonts.Tor Andersson
Do not cache PDF fonts, since they have custom metrics and encodings that cannot be shared. This is primarily to speed up font loading for EPUB, PDF appearance synthesis, and any other uses of default metrics and unicode encoded fonts.
2018-06-22Add pdf_dict_get_name function.Tor Andersson
2018-06-22Check pointer for NULL in fz_free before locking.Tor Andersson
2018-06-21Allow signature saving using pdf_write_documentPaul Gardiner
It is safe to save a document with unsaved signatures to an fz_output, provided it supports fz_stream_from_output.
2018-06-12Run both V and F additional actions when setting field values.Tor Andersson
2018-06-11Use bin2coff to generate font data blobs object files.Tor Andersson
This is the windows equivalent of objcopy or ld -r binary. We need different bin2coff font object files for 32 and 64 bit builds, so put the font object files in AdditionalDependencies. Revamp Windows builds to use bin2coff. Fix bin2coff to not use '-' in symbol names. Add a new project file to make bin2coff. Add a .rules file to tell MSVC how to call the built version of bin2coff. Update libresources build to use this rules file. Update noto.c to correctly find the symbols we make.
2018-06-02Rework XObject form creation/updating.Tor Andersson
2018-06-02mutool show: Add support for wildcards in path syntax.Tor Andersson
Example: mutool show $PDF pages/*/Resources/Fonts/*/Subtype
2018-06-02Add a fz_strnlen function (strnlen is not standard C).Tor Andersson
2018-06-01Fix loss of reference to focussed annotation when rereading annotationsPaul Gardiner
2018-05-18Fix 699368: Remember 'sent' text state in sanitize filter.Tor Andersson
2018-05-18Fix segfault in SVG parser when encountering text data.Tor Andersson
fz_xml_tag returns NULL for non-tag (i.e. text) elements. Use the fz_xml_is_tag function instead of comparing strings.
2018-05-17mutool extract: Remove spurious 'break' statement and fix double free.Tor Andersson
2018-05-16Don't use pdf_load_object in pdfextract.cTor Andersson
2018-05-16Remove unused variable.Tor Andersson
2018-05-16Keep JBIG2 image data compressed in fz_compressed_buffer.Tor Andersson
2018-05-16Remove needless deep copy of resource dictionary.Tor Andersson
Also don't bother adding an indirect object for the top resource dict.
2018-05-16js: Add Shade.bound function and bbox device example.Tor Andersson
2018-05-16Purge unused functions.Tor Andersson
2018-05-16Restore Emoji font.Tor Andersson
The Noto symbol font has been split into two. The second symbol font only contains a subset of the emojis, so reinstate the real emoji font and add both symbol fonts to the fallback chain.
2018-05-15Bug 699351: Handle glyphs with uncomputable width.Sebastian Rasmussen
Previously if a glyphs units per em was 0 we'd try to divide by zero, now mupdf assumes a default value and continues.
2018-05-11Fix 699332: Copy resources when cleaning content streams.Sebastian Rasmussen
Previously if both cleaning and sanitizing content streams the pages' resource dictionaries would retain the actually used resources. If the content streams were only cleaned and not sanitized the page's resource dictionaries were incorrectly emptied. All resources, whether used or not, ought to be retained, as is the case after this commit.
2018-05-10Use fz_malloc_no_throw() in JPEG/DCT decoder.Sebastian Rasmussen
Suppose an application that uses MuPDF implements its own allocator that limits the amount of memory that may be allocated. When that condition occurs fz_malloc() will throw an exception, this exception would then be thrown right back to MuPDF without allowing for libjpeg to free any of the memory it has allocated. After this commit fz_malloc_no_throw() is called, which under the same conditions would simply return NULL. allowing for libjpeg to free what ever allocations it has done, and return to MuPDF with an error just like before.
