Rob Wu	fd29bb0c57	Subtract start offset for xrefs in recovery mode Xref offsets are relative to the start of the PDF data, not to the start of the PDF file. This is clear if you look at the other code: - In the XRef's readXRefTable and processXRefTable methods of XRef, the offset of a xref entry is set to the bytes as given by a PDF file. These values are always relative to the start of the PDF file (%PDF-). - The XRef's readXRef method adds the start offset of the stream to Xref entry's offset: "stream.pos = startXRef + stream.start". Clearly, this line assumes that the entry offset excludes the start offset. However, when the PDF is parsed in recovery mode, the xref table is filled with entries whose offset is relative to the start of the stream rather than the PDF file. This is incorrect, and the fix is to subtract the start offset of the stream from the entry's byte offset. The manually created PDF file serves as a regression test. It is a valid PDF, except: - The integer to point to the start of the xref table and the %%EOF trailer are missing. This will activate recovery mode in PDF.js - Some junk was added before the start of the PDF file. This exposes the bad offset bug.	10 years ago

Jonas Jenwald	aa3a64e975	Skip mapping of CIDFontType2 glyphs when the font either has a \|IdentityToUnicodeMap\| or a \|toUnicodeMap\| with 65536 elements (issue 5677) This patch slightly extends the heuristics used when trying to skip mapping of missing glyphs. Fixes 5677.	10 years ago

Jonas Jenwald	97385587a8	Add a test-case for issue 6099 - CalRGB color space where the parameters are a \|Ref\| The issue is already fixed by PR 5748, but we didn't have access to a suitable test-case. Thanks to issue 6099, we are now able to add one!	10 years ago
Jonas Jenwald	5eae3e29c5	Map missing glyphs to the notdef glyph for TrueType (3, 1) fonts (issue 6068) Fixes 6068. The most notable issue with the font in question is that the `differences` array contains lots of strange entries (of the type `uniXXXX`, instead of proper glyph names).	10 years ago
Jonas Jenwald	6f2f0700b7	Don't map glyphs to certain problematic Thai/Lao Unicode locations (issue 5994) This patch depends on PR 5990. According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-fallback.cc#38, certain Thai/Lao characters are treated as special by the font shaping code in Firefox. Further down in that file, https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-fallback.cc#216, the vertical position of glyphs is modified, which should thus explain why some glyphs end up in the wrong position in the PDF file. Fixes 5994.	10 years ago

Jonas Jenwald	44240798be	Convert UTF8 encoded passwords to ISO-8859-1 for \|R = 6\| encryption (issue 6010) For passwords where the encoding already is correct, the conversion is a no-op. Also, since `encodeURIComponent` might throw, we need to make sure that we handle that case too. Fixes 6010.	10 years ago

Jonas Jenwald	0365baf5ab	Fall back to the \|defaultEncoding\| when no valid "post" table is found in TrueType fonts (bug 1050040) Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1050040. With this patch the file is completely readable, but given that the font is broken enough to be rejected by OTS the rendering differs slightly from Adobe Reader. Note: the PDF file is sufficiently broken that even Adobe Reader complains about the font, and also about another more general issue.	10 years ago

Jonas Jenwald	760222cf0b	Handle the Encoding being a dictionary in PartialEvaluator_preEvaluateFont (bug 1157493) This is a regression from PR 4423. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1157493.	10 years ago

Jonas Jenwald	4c2ad3bc7b	Ensure that entries in the Differences array of Type1 fonts are either numbers or names This patch is yet another installment in the (never ending) series of bugs in PDF files with non-embedded fonts. Fixes http://www.int.washington.edu/talks/WorkShops/int_08_37W/People/Franz_M/Franz.pdf.	10 years ago
Jonas Jenwald	fda858ae33	Don't map glyphs to certain problematic General Punctuation Unicode locations (bug 911034) Fixes the remaining missing characters in https://bugzilla.mozilla.org/show_bug.cgi?id=911034. For reference, see http://www.unicode.org/charts/PDF/U2000.pdf (and also http://en.wikipedia.org/wiki/General_Punctuation_%28Unicode_block%29).	10 years ago
Jonas Jenwald	2b1a13ba28	Don't map glyphs to Unicode position 0x0E33, i.e. Thai character SARA AM (bug1046314) A similar approach as in PR 5705. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1046314. According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-complex-thai.cc#270-365, `0x0E33` is treated as a special case (by the font shaping code in Firefox). Hence it seems reasonable to skip it when adjusting the font mapping.	10 years ago

Jonas Jenwald	4a9ff471c4	Correctly detect the presence of the Adobe specific APP14 JPEG marker (bug 1140761) According to the specification, http://partners.adobe.com/public/developer/en/ps/sdk/5116.DCT_Filter.pdf#G3.851943, the content of the marker segment should begin with `Adobe`, and not `Adobe\x00` as the code currently look for. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1140761. Fixes the colour conversion part of issues 4090 and 5623.	10 years ago

Jonas Jenwald	82f73bc9f4	Add a \|text\| test-case for issue 5421 Prior to PR 4259, we incorrectly ignored `toUnicode` for Type3 fonts. Since we now handle that correctly, this patch adds a `text` test-case to prevent regressions.	10 years ago
Jonas Jenwald	f81fc9091a	Correctly detect OpenType font files with CFF data Fixes 5334. Fixes 215. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1125614. According to the specification, http://www.microsoft.com/typography/otspec/otff.htm, OpenType font files with CFF data should have `OTTO` in the header.	10 years ago
Jonas Jenwald	0a3341dadc	Don't map glyphs to Unicode "Dotted circle" combining mark (bug 1108301) It seems that `0x25CC` is another bad spot for charCodes. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1108301.	10 years ago

Jonas Jenwald	1fea44ce14	Ensure that \|get fingerprint\| doesn't fail if the ID is not an array (issue 5599) According to the [PDF specification](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#page=51) the `ID` should be an array. To prevent errors if the PDF file violates that part of the spec, check that the `ID` is actually an array. Fixes 5599.	10 years ago

Jonas Jenwald	d8b905048b	Add fallback for non-embedded "Century Gothic" CIDFontType2 font (issue 4722 and bug 879561) According to practical experiments, falling back to "Helvetica" when we encounter a non-embedded "[Century Gothic](http://en.wikipedia.org/wiki/Century_Gothic)" `CIDFontType2` font seems to work well. (Also, the section on Wikipedia about "Printer ink usage" might provide some anecdotal evidence that Century Gothic is a fairly standard sans-serif font.) Obviously this patch doesn't make "Century Gothic" fonts render perfectly, as is often the case with non-embedded fonts, but all the text is now legible in the referenced issues. Fixes 4722.

Jonas Jenwald	3ea81019fe	Add a (linked) test case for bug 1108753 (PR 5276) When submitting PR 5276 there wasn't a good PDF file to include in the test suite. However, with https://bugzilla.mozilla.org/show_bug.cgi?id=1108753, we now have a better source for a test file, hence this patch.	11 years ago
