2018-06-08Use FPDFText_GetBoundedText() to get the visible text in a test.Lei Zhang
Add a test PDF with multiple pages, each with a different media box and crop box. Demonstrate how FPDFText_GetText() gets all the text on the page, and how FPDFText_GetBoundedText() with the right bounding boxes gets only the visible text on the page. Also fix a small nit in CPDF_TextPage::GetTextByRect() found while writing this CL.

A workaround for this problem is avoiding declaring in same file extern and explicit class template for them.

2018-05-31Fix font regression in AdjustMMParamsNicolas Pena
Commit 2334660 changed the |dest_width| in CFX_Font::AdjustMMParams to unsigned, but this means that dest_width - min_width becomes unsigned, which is wrong because the subtraction could be negative. This CL fixes this bug.

2018-05-30Exclude certain colorspace types for calculating transparency backdrop color.Lei Zhang
Per discussion for the "CS" entry in the PDF 1.7 spec table 7.13, several types of colorspaces do not meet the requirements of this particular colorspace entry. In terms of implementation, this avoids hitting a NOTREACHED() in CPDF_PatternCS::GetRGB().

2018-05-30Make CPDF_Document cache CPDF_PagesTom Sepez
We cache pages not by page number, which can bounce around as pages are inserted or removed, but by page dictionary's object number. Since the page may be created under one function and used under another, we can't take the shortcut of not instantiating a render cache nor not parsing the page.

This is a manual revert of the CL at: https://pdfium-review.googlesource.com/c/pdfium/+/32159 The only file manually changed was cpdf_renderstatus.cpp Reason for revert: the bug below shows that sometimes the vector size used is larger than the parameter given to CFX_FixedBufGrow. Thus, we will revert, then add vectors using std::max unless it's clear from the code that the code will never access indices outside.

2018-05-25Make CPDF_Page retainable.Tom Sepez
Small step to reducing the differences between XFA and non-XFA. We still use the RetainPtr pretty much as if it were an unique_ptr, in that we're not yet caching pages and handing out multiple pointers to the same page in the non-XFA case. The one change is in page view cleanup, where we no longer need a boolean and can take (sufficient) page ownership with a RetainPtr. Tidy up some document.h -> page.h -> document.h circular inclusion while we're at it. NOTE: Wait for imminent branch to pass before landing. We'll want this to bake a while.
