Defined in:
lib/ea/svg/ea_emitter/element/bcol_decoder.rb

Overview

Decodes EA's BGR-encoded BCol/LCol integers into "#RRGGBB" hex strings. EA stores color as a Win32 COLORREF: R in low byte, G in mid byte, B in high byte.

Returns nil when bgr_int is nil OR equals -1 (EA's sentinel for "no color override" — callers fall through to a stereotype-derived default).
