Enum pdf_writer::types::ColorSpaceOperand

pub enum ColorSpaceOperand<'a> {
    DeviceGray,
    DeviceRgb,
    DeviceCmyk,
    Pattern,
    Named(Name<'a>),
}

A color space operand to the CS or cs operator.

Variants

DeviceGray

The predefined, parameterless gray device-dependent color space. Needs no further entries in the resource dictionary. This is not a normed color space, meaning the exact look depends on the device.

Writing cs with this is equivalent to writing g.

DeviceRgb

The predefined, parameterless RGB device-dependent color space. Needs no further entries in the resource dictionary.

Writing cs with this is equivalent to writing rg.

DeviceCmyk

The predefined, parameterless CMYK device-dependent color space. Needs no further entries in the resource dictionary.

Writing cs with this is equivalent to writing k.

Pattern

A pattern with color defined by the pattern itself.

When writing a cs operation with this, you must also write an scn operation with a name pointing to an entry in the current resource dictionary’s pattern dictionary.

Named(Name<'a>)

A named color space defined in the current resource dictionary’s color space dictionary.

When this points to a pattern color space, You must also write an scn operation with a name pointing to an entry in the current resource dictionary’s pattern dictionary. The color will be taken from the tint passed to SCN and not the pattern itself.

Trait Implementations

impl<'a> Clone for ColorSpaceOperand<'a>

fn clone(&self) -> ColorSpaceOperand<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColorSpaceOperand<'a>

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

Formats the value using the given formatter.

impl<'a> From<Name<'a>> for ColorSpaceOperand<'a>

fn from(name: Name<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for ColorSpaceOperand<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for ColorSpaceOperand<'a>

fn eq(&self, other: &ColorSpaceOperand<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
