All codes

  • Type: error
  • Kind: input (the input is malformed beyond what tolerance repairs)

What happened

IccProfile::new (lamina-build) rejected the bytes.

Why

An ICC profile (ICC.1:2010) starts with a 128-byte header holding its size, the acsp signature, its class and its data colour space. PDF’s ICCBased colour spaces (ISO 32000-2 §8.6.5.5) take Gray, RGB, CMYK and Lab profiles; the builder takes Gray, RGB and CMYK (Lab components fall outside [0, 1] and need a /Range, not supported yet), and device-link, abstract and named-colour profiles can’t be used.

How to fix

Pass the complete bytes of an input, display, output or colour-space profile with a Gray, RGB or CMYK data colour space.

Example

let profile = IccProfile::new(b"not a profile".to_vec())?; // invalid-icc-profile
