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.

2018-08-16If rows need to overflow in a PDF417 barcode, keep it to a minimum.Henrique Nakashima
By using mincols as fallback, the exact opposite is done. Maxcols should be used instead to minimize the size. This is important so the next fix (https://pdfium-review.googlesource.com/c/pdfium/+/40350) does not break a test that was working well by coincidence.

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.
