2018-06-12Fill m_ContentStream field in CPDF_PageObject.Henrique Nakashima
From the comment of CPDF_PageObject::GetContentStream(): """ Get what content stream the object was parsed from in its page. This number is the index of the content stream in the "Contents" array, or 0 if there is a single content stream. If the object is newly created, -1 is returned. If the object is spread among more than one content stream, this is the index of the last one.

2018-06-04Do not merge content streams to parse them.Henrique Nakashima
Removed the PrepareContent() step in CPDF_ContentParser, as its goal was to merge these streams. In Parse(), now loop through the m_StreamArray and parse each stream separately.

2018-05-16Cleanup CPDF_ContentParserDan Sinclair
This CL cleans up the CPDF_ContentParser code. The m_bIsDone flag has been removed and a kComplete stage added. Each of the processing methods returns the next stage instead of setting the internal flag automatically. The infinite loop is removed for simpler straight line code.

2017-08-31Prevent duplicate parses of same data, in the same recursive descentRyan Harrison
When parsing if there is a loop in the data being parsed, the recursions will just keep cycling until it exhausts memory and crashes. This CL introduces a parsed set, which a reference to is passed down the descent. If the data being parsed at a specific stage of the descent is already in the parsed set, then the parse returns at that point.

2017-06-28Set default graphics before generating page contentsNicolas Pena
In this CL, the content generator sets some default graphics states before processing the page objects. In particular, a default ExtGState is now set before processing, and the last CTM is now stored right after parsing finishes: the only command to change matrix is ctm, and it concatenates, so inverting requires knowing the current value.
