@jonahwilliams jonahwilliams commented Aug 27, 2024

When computing whether or not an entity can be coerced into src blend from srcOver, take into account that stroke geometries may modulate with alpha to emulate stroke widths less than 1.0.

While we're at it, update several computations to use max basis XY (from flutter/flutter#153451 ) since that can lead to incorrect stroke width computations in the presence of canvas scaling.

Most of the changes update the APIs that used to take a const Entity& entity to instead use the const Matrix& transform, since that is all we used the entity for.

See screeenshots in flutter/flutter#154178 (comment)

Fixes flutter/flutter#154178

ASSERT_TRUE(entity.size() >= 1);
ASSERT_TRUE(contents->IsOpaque());
ASSERT_TRUE(contents->IsOpaque(matrix));

Super minor nit: Just IsOpaque({})?
