2018-10-11Fix double V8 initialization with fuzzers.Lei Zhang
Commit 95860d7 added some new fuzzers, but they try to use both the generic fuzzer's initialization code, as well as their own custom initialization code. Add a new "pdfium_public_fuzzer" GN template for these new fuzzers, so they use their own initialization code rather than the generic one.

2018-08-22Properly handle language markers in decoded textRyan Harrison
In text like document title 0x001B is used as a marker for the beginning/end of a language metadata section. Currently PDFium does nothing with this data, but when returning the 'decoded' text it needs to be stripped out. The existing code assumed that the two bytes following a marker would be the data to be removed and did nothing to track if it was in/out of one of these regions. This led to a situation where it would always strip the two bytes following the region, since it assumed the end marker was the beginning of a new region. This CL corrects the detection and handling of these regions, and adds a regression test for the reported bug.

2018-08-21Optimize rendering of two dimensional barcodes: defer upscale.Henrique Nakashima
Defer upscaling as late as possible so that intermediary data structures are smaller. Made a couple of changes along the way to preserve the barcode correctness and fix some padding issues. For my example, this is a ~21x improvement in rendering time, down from ~190ms per barcode to ~9ms.

2018-08-16Add a way to save a barcode generated bitmap to a .png.Henrique Nakashima
This is useful for debugging and validation purposes. The hashes that are in BarcodeTest are not necessarily for valid outputs. This CL refactors the code in embedder_test.png that already does this, moving it to testing/utils where unit tests can access it too.

2018-08-16Optimize rendering of two dimensional barcodes: deduplicate regions.Henrique Nakashima
Reduce the logical size of the barcode by removing unnecessary region duplication. As far as I can tell, the line thickness is useless and the aspect ratio causes arbitrary changes in rounding, but ultimately the dimensions of a barcode are defined by its width and height, rather than by this ratio. The improvement with this CL is from ~580ms to ~390ms per barcode, so about 1.5x. Combined with https://pdfium-review.googlesource.com/c/pdfium/+/40010 the improvement is to ~15ms, which is about 39x. This also fixes the rendering of the barcode in the pixel and corpus tests. You can verify this pointing a barcode reader app at the screen. It does not however fix every case, as the unit test is still unreadable.

2018-08-14Remove CFX_BufferSeekableReadStream.Lei Zhang
Replace it with CFX_ReadOnlyMemoryStream, which does the same thing. Take some checks from CFX_BufferSeekableReadStream and add them CFX_ReadOnlyMemoryStream.
