From ebc48efe37d1aad181862f610726e0112f1cebb0 Mon Sep 17 00:00:00 2001 From: Jingning Han Date: Wed, 7 Oct 2015 11:43:48 -0700 Subject: [PATCH] Use explicit block position in foreach_transformed_block Add the row and column index to the argument list of unit functions called by foreach_transformed_block wrapper. This avoids the repeated internal parsing according to the block index.
