From dc2bb9ad21a10550fb451d7c842c63cbce98045b Mon Sep 17 00:00:00 2001 From: Henrique Nakashima Date: Tue, 21 Aug 2018 19:50:17 +0000 Subject: Optimize rendering of two dimensional barcodes: defer upscale. 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.
