Subject: [PATCH] For ICC profile validation, have cups id iteself as DeviceN
|
|
|
|
Give the range of color spaces and models that cups supports, we can't
|
|
reasonably provide (or expect others to provide) output ICC profiles for all
|
|
cases.
|
|
|
|
For the purpose of profile validation, have it claim to be DeviceN and benefit
|
|
from the extra tolerance in profiles allowed for that class of device.
