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.

2018-08-16Allow PDF417 barcodes to reduce modules by shaving off padding.Henrique Nakashima
The way it was working before is: Look at the width and height provided for the barcode. If the maximum number of codewords to fit in that space was within the spec limits (1 <= cols <= 30 and 3 <= rows <= 90), cram as many codewords as possible. The unused space was filled with padding. With this CL, instead look at the amount of content that needs to fit into the barcode and favor fewer codewords rather than as many as possible.

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.

2018-08-08Move ByteString::FromUnicode() to WideString::ToDefANSI()Tom Sepez
Turns out that "FromUnicode" is misleading in that, on linux, it simply removes any characters beyond 0xFF and passes the rest unchanged, so no unicode decoding actually takes place. On Windows, it passes it into the system function specifying FX_CODEPAGE_DefANSI, converting it into the so-called "default ANSI code plane", passing some characters, converting others to '?' and still others to 'A'. Either way, nothing resembling UTF8 comes out of this, so pick a better name. These now immediately look suspicious, so a follow-up CL will see which ones should really be WideString::UTF8Encode() instead. Making this a normal method on a widestring rather than a static method on a bytestring feels more natural; this is parallel to the UTF8Encode and UTF16LE_Encode functions. Add a test that shows these conversions.

This changes the implementation for the specific bug listed and proactively fixes it in the other overrides. The general bug here is that if you concat a WideString in a tight loop without first reserving space, each call will cause an allocation size change and memcpy.

This fixes a number of instances where a value is written out to a variable, but never used in the barcode. There are three different types of fixes employed in this CL. If the non-use is a bug, then rewrite the code to actually use the value. If it is an assignment with no side effects, then just remove the entire line. Finally if it is an assignment of a function return value, cast it to void instead to clearly mark that the return is being ignored. Issues found with Clang Static Analyzer.

2018-05-25Reserve space for code words when creating encoder contextRyan Harrison
During encoding, the code is going to walk through every character in m_msg and determine what values need to be added to m_codewords. The ceiling on the number of characters being added to m_codewords is the length of m_msg, so reserving enought space in advance. This prevents thrash related to incrementing the string and thus resizing in a tight loop.

In the test case from the bug, the majority of the time is being spent resizing Widestring internal buffers, since += is being called in a tight loop.
