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.

2017-04-06Change some fxbarcode to use return values.Lei Zhang
No caller cares about the exception values anyway. Remove the unused ones. Also use more std::unique_ptr to stop potential leaks.

2017-03-29Move xfa/fxbarcode fxbarcode/Dan Sinclair
Nothing in fxbarcode/ depends on XFA code. This CL moves xfa/fxbarcode to be fxbarcode/ and creates a static_library for fxbarcode which is depend on by the xfa library.
