Module: Dragonfly::GeometryBridge

Defined in:
lib/dragonfly/geometry_bridge.rb

Overview

Translates legacy ImageMagick geometry strings (e.g. "300x300#c",
"640>x") into libvips/Dragonfly option hashes so historical cached
URLs and older callers continue to render correctly after the move
to libvips. See the file header for the full mapping.
