19.8 KiB regression in resource_sizes (MonochromePublic.apk) at 552559:552559

Project Member Reported by huangs@google.com, Apr 21 2018

Issue description

Caused by “Enable skcms in Skia”

Debugging size regressions is documented at: https://chromium.googlesource.com/chromium/src/+/master/docs/speed/apk_size_regressions.md#Debugging-Apk-Size-Increase

Based on the graph: 19.8 KiB of native code.

It looks to me that the size increase is expected.
Feel free to close as “Won't Fix” unless you can see some way to reduce size.

Assigning to brianosman@google.com because this is the only CL in range:
Enable skcms in Skia

This switches Skia to use skcms for color space transformation. Layout
test changes are expected, but should be minor.

Correct, this is intentional, and temporary.  This CL switched color management from code path "A" to code path "B", but we're still linking in "A".  Once we remove it (hopefully before this next milestone branches), we think there should be a net size win.
