Module: Idml::Render::IccProfile

Defined in:
lib/idml/render/icc_profile.rb

Overview

Locates an sRGB ICC profile for PDF/A output intent embedding. The idml gem does not bundle a binary ICC asset; instead, this helper probes a small set of well-known locations in priority order and returns the first match as raw bytes.

Priority:

1. `ENV["IDML_SRGB_ICC"]`

Returns nil when no profile is available — callers (Pipeline) should skip ICC embedding in that case rather than raising.
