Struct IccProfile

pub struct IccProfile<'a> { /* private fields */ }

Writer for an ICC profile stream.

This struct is created by Chunk::icc_profile.

Implementations

impl<'a> IccProfile<'a>

pub fn n(&mut self, n: i32) -> &mut Self

Write the /N attribute. Required.

The number of components in the color space. Shall be 1, 3, or 4.

pub fn alternate(&mut self) -> ColorSpace<'_>

Write the /Alternate attribute with a color space.

The alternate color space to use when the ICC profile is not supported. Must be a color space with the same number of components as the ICC profile. Pattern color spaces are not allowed.

pub fn alternate_name(&mut self, name: Name<'_>) -> &mut Self

Write the /Alternate attribute with a name.

The alternate color space referenced by name must be registered in the current resource dictionary.

pub fn range(&mut self, range: impl IntoIterator<Item = f32>) -> &mut Self

Write the /Range attribute.

Specifies the permissible range of values for each component. The array shall contain 2 × N numbers, where N is the number of components in the color space. The array is organized in pairs, where the first value shall be the minimum value and the second shall be the maximum value.

pub fn metadata(&mut self, metadata: Ref) -> &mut Self

Write the /Metadata attribute.

A reference to a stream containing metadata for the ICC profile.

Methods from Deref<Target = Stream<'a>>

pub fn filter(&mut self, filter: Filter) -> &mut Self

Write the /Filter attribute.

pub fn decode_parms(&mut self) -> DecodeParms<'_>

Start writing the /DecodeParms attribute.

This is a dictionary that specifies parameters to be used in decoding the stream data using the filter specified by the /Filter attribute.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.

Trait Implementations

impl<'a> Deref for IccProfile<'a>

type Target = Stream<'a>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for IccProfile<'a>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
