2018-11-13Add more encoding tables.Tor Andersson
Add tables for Windows-1250, Windows-1251, and ISO-8859-1. Also add unicode_from_encoding tables. Move encodings from PDF namespace to Fitz.
2018-11-13Use first character's bbox even if it is empty.Tor Andersson
Otherwise we get unsightly [0 0 0 0] bounding boxes for lines with a single zero area character.
2018-11-13Bug 697206: Tweak when to use the PDF font metrics in fz_advance_glyph.Tor Andersson
Only use the PDF font metrics for stretched substitute fonts, in all other cases, trust the embedded font file instead.
2018-11-13Bug 700143: Ignore duplicate text objects in text extraction.Tor Andersson
Rendering modes like fill+stroke or fill+stroke+clip send the same text object multiple times. Only extract the text from the first instance.
2018-11-13Bug 692592: Handle relative file links.Tor Andersson
The core library doesn't know where a document comes from, since we can open it as a stream, etc. Let the viewer handle relative file URLs.
2018-11-13Bug 699217: Show whether outline items are open in 'mutool show outline'.Tor Andersson
A '+' prefix indicates an open branch. A '-' prefix indicates a closed branch. A ' ' prefix indicates a leaf node.
2018-11-13Use fz_image.imagemask field when adding PDF image resources.Tor Andersson
Don't pass the information as a separate argument.
2018-11-13js: Add PDFDocument.loadImage() function.Tor Andersson
2018-11-13js: Use Image.toPixmap arguments.Tor Andersson
2018-11-12Fix 699094: Never decompress JPX streams in mutool clean.Tor Andersson
2018-11-12Bug 699992: Use feBlend filters in SVG output for PDF blendings.Robin Watts
This doesn't cover all the PDF options, but it's better than nothing. This does mean we have to "enable-background" for all SVG files whether they use blending or not.
2018-11-12Bug 700154: Don't pass blends into groups within softmasks.Robin Watts
When generating a softmask, which is to be rendered with a blend, don't pass that blend down into the rendering of the softmask. Otherwise the blend gets used twice. In the example given this is causing the content to disappear.
2018-11-12Remove bitrotted and not working PDF portfolio code.Tor Andersson
Extracting embedded files can be trivially done with 'mutool show' or a simple mutool run script. The portfolio creation code is incomplete, and would require a lot of work and testing with Adobe in order to be useful.
2018-11-12Clean up pdf-portfolio.cTor Andersson
Remove pointless paranoia checks. Move the check whether it has already been loaded into load_portfolio().
2018-11-12Fix 697728: Use UTF-8 strings in PDF portfolio functions.Tor Andersson
2018-11-12Fix 697913: Make sure PDF portfolios are saved as version >= 1.7.Tor Andersson
2018-11-12Remove confusing flag define.Tor Andersson
What's the difference between PDF_OBJ_FLAG_MARK and PDF_FLAGS_MARKED? PDF_OBJ_FLAG_MARK is used to flag an xref entry as one that we want to keep cached with the pdf_mark_xref/pdf_clear_xref_to_mark functions. PDF_FLAGS_MARKED is used to detect unwanted recursion in PDF structures. Renaming the xref_entry.flags field to xref_entry.marked should remove this source of potential confusion.
2018-11-12Remove stray js_endtry in obj.asString().Tor Andersson
2018-11-09Fix 695390: Increase number of samples in Type 1 function shadings.Tor Andersson
15 years have passed since we first set the sampling to a 32x32 mesh. Quadrupling it to 64x64 sounds about right to me.
2018-11-08Fix 699343: Skip spaces before data in DCTDecode filter.Tor Andersson
2018-11-08Fix 699310: Add -q option to mudraw to suppress 'page %d' messages.Tor Andersson
Useful if printing text or traces to stdout. Be quiet automatically if printing to stdout.
2018-11-08Fix 699352: Call begin_layer for all marked content in PDF.Tor Andersson
Since we call end_layer without distinction, we should also call begin_layer the same way. Also change the XML to emit separate tags for beginning and ending a layer, since there is no guarantee the layer calls will be neatly nested with clipping pushes and pops; nor is there a guarantee that the PDF will even balance the BMC/BDC and EMC operators.
2018-11-07Fix typo.Tor Andersson
2018-11-07Fix 698971: Detect ICC colorspace mismatch in TIFF loader.Tor Andersson
Make sure that the ICC colorspace has the same number of components as the photometric interpretation.
2018-11-07Use utility parsing functions in svg_parse_transform.Tor Andersson
2018-11-07Fix 699747: Apply viewBox transform.Tor Andersson
2018-11-07Resolve objects in pdf_debug_obj().Sebastian Rasmussen
2018-11-07Write placeholder appearance streams for digital signatures.Tor Andersson
A proper appearance stream is written when signing with a certificate. This is just to create a placeholder appearance when the original document did not write one.
2018-11-07Fix 700140: Ask LCMS transform to copy alpha channels.Tor Andersson
2018-11-07Make compression bomb detection optional.Tor Andersson
2018-11-07pnm: Take alpha into account when skipping over image data.Sebastian Rasmussen
2018-11-07Fix double header output in muraster.Robin Watts
Also fiddle the #ifdeffery to get sane defaults.
2018-11-07Add explicit jmp_buf dereferencing to allow using fz_try from C++.Tor Andersson
2018-11-07Handle bogus font ascender and descender values.Tor Andersson
2018-11-07Fix 700030: Use actual font glyph widths when extracting text.Tor Andersson
Only use the PDF character widths when also stretching glyphs to match the PDF metrics.
2018-11-07Fix 700030: Tweak text extraction space adding heuristics.Tor Andersson
Ignore space-sized backward motions. Assume that these motions are either extreme levels of kerning, or something else fishy going on.
2018-11-07Fix 700053: Add 'decrypt' option to pdf_save_document.Tor Andersson
This option is exposed as the -D flag to mutool clean. Allow saving a document without encryption. The next step is to allow saving a document with new encryption, but this may require a fair amount of rejigging since the PDF write code to keep separate doc->crypt objects for decryption and encryption.
2018-11-07Fix writing encrypted PDF files with 'decompress' option.Tor Andersson
2018-11-07Fix 700043: Don't assume a font is t3 just because fz_outline_glyph fails.Tor Andersson
2018-11-06Update AFParseDateEx to handle dates as a contiguous string of digits.Paul Gardiner
Update to match Adobe Reader's behaviour. This fixes bug #700128.
2018-11-01Bug 700040: tar: Handle posix, ustar and v7 tar formats.Sebastian Rasmussen
These formats are all almost identical to GNU tar format.
2018-10-26Guard all calls to the passthrough device in the test device.Sebastian Rasmussen
Without guards the device calls might end up with a device pointer being NULL, causing segfaults.
2018-10-26Drop documents while exception progressing files in mutool merge.Sebastian Rasmussen
2018-10-26Avoid dropping stream/color converter twice upon exception.Sebastian Rasmussen
2018-10-26Rewrite try/always/catch macros to allow fz_context to be opaque.Tor Andersson
Hide fz_stack_slot and exception handling details too. Also make sure we have an initialized jmp_buf so we can safely throw from the always block even in the exception stack overflow case.
2018-10-26Use 14 bits of precision for image drawing, to allow for larger images.Tor Andersson
Now the image size limit is 131072 x 131072 instead of 32768 x 32768.
2018-10-25Make fixed point math precision in image drawing a #define.Tor Andersson
2018-10-25Handle premultiplied alpha in generic pixmap color conversion.Tor Andersson
2018-10-25Handle premultiplied alpha in pixmap color conversions (CMYK only).Tor Andersson
2018-10-25Fix asserts and checks in fast_xxx_to_yyy functions.Tor Andersson
fast_rgb_to_cmyk had || instead of && so always triggered incorrectly. Only throw, no need to both assert and throw.
