2018-03-20Change ArgbToColorRef() to ArgbToAlphaAndColorRef().chromium/3377Lei Zhang
Since that is what it really returns. Add a replacement ArgbToColorRef() that only returns a FX_COLORREF, and remove a duplicate implementation. Then update callers and only use ArgbToAlphaAndColorRef() where appropriate. Also update comments to explain what FX_COLORREF is.

2018-03-19Calculate AP for multi-line markup annotations correctlyRalf Sippl
Currently, when constructing AP for multi-line markup annotations, we only take into account the first set of quadpoints, resulting in only the first line of the annotation being displayed if the annotation spans multiple lines. This CL, initially written by Jane Liu <janeliulwq@google.com> (https://pdfium-review.googlesource.com/12010) takes into account all the quadpoints, so multi-line annotations can be displayed correctly.

2018-02-16Correct mapping text to characters for characters missing from fontRyan Harrison
When parsing text streams there is an internal character list that is generated of all the characters in the stream. Additionally a text string is generated that is exposed via the public API. This string will have all of the printing, i.e. non-control characters, in it. For characters that are not in the font of the stream the unicode, but printable, the character 0xFFFE is used in the text to indicate a missing character. This a non-printing character to indicate non-unicode. The internal character list gets a Unicode value 0x0 when there isn't a glyph in the font for it and the original character code is preserved. This means that when generating the mapping between text string and character list, the code is mistakenly thinking that the unprintable character was not present in the text string. I have changed the check in the mapping generation code to correctly account for this. Additional investigation is needed to determine if inserting 0xFFFE in the text is the correct behaviour. This patch resolves an issue where the find highlights in Chrome for a PDF would be offset when there are unprintable characters in a stream.
