Struct OutputIntent 

pub struct OutputIntent {
    pub subtype: String,
    pub output_condition_identifier: Option<String>,
    pub output_condition: Option<String>,
    pub info: Option<String>,
    pub dest_output_profile: Option<ObjectId>,
    pub dest_profile_components: Option<i64>,
}

One /OutputIntents entry.

Fields

subtype: String

/S subtype name, e.g. "GTS_PDFX", "GTS_PDFA1", "ISO_PDFE1". Empty when the entry omits /S.

output_condition_identifier: Option<String>

/OutputConditionIdentifier — the characterized printing condition, usually a registry key such as "CGATS TR 001". Decoded as a text string (UTF-16BE with BOM, else PDFDocEncoding bytes).

output_condition: Option<String>

/OutputCondition — human-readable condition name, if present.

info: Option<String>

/Info — additional human-readable description, if present.

dest_output_profile: Option<ObjectId>

/DestOutputProfile — the embedded ICC profile stream’s object id. None when the intent only names an external (registry) profile.

dest_profile_components: Option<i64>

/N (component count) read off the /DestOutputProfile stream dict without decoding the profile. None when the key is absent/unreadable.

Implementations

impl OutputIntent

pub fn has_cmyk_profile(&self) -> bool

Cheap heuristic — usable without decoding the profile — for whether this intent looks like it can colour-manage DeviceCMYK: it has an embedded profile whose /N is 4 or absent. It is advisory (e.g. for zpdf info): the render path is authoritative, accepting a profile only on its compiled channel count, so a profile with a mistyped /N is still honoured there even though this returns false.

Trait Implementations

impl Clone for OutputIntent

fn clone(&self) -> OutputIntent

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OutputIntent

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
