Struct ImageMetadata 

#[non_exhaustive]
pub struct ImageMetadata {
    pub id: ImageId,
    pub size: PxSize,
    pub density: Option<PxDensity2d>,
    pub is_mask: bool,
    pub original_color_type: ColorType,
    pub parent: Option<ImageEntryMetadata>,
}

Represents decoded header metadata about an image.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: ImageId

Image ID.

size: PxSize

Pixel size.

density: Option<PxDensity2d>

Pixel density metadata.

is_mask: bool

If the pixels are in a single channel (A8).

original_color_type: ColorType

Image color type before it was converted to BGRA8 or A8.

parent: Option<ImageEntryMetadata>

Extra metadata if this image is an entry in another image.

When this is None the is the first ImageEntryKind::Page in the container, usually the only page.

Implementations

impl ImageMetadata

pub fn new( id: ImageId, size: PxSize, is_mask: bool, original_color_type: ColorType, ) -> Self

New.

Trait Implementations

impl Clone for ImageMetadata

fn clone(&self) -> ImageMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageMetadata

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

Formats the value using the given formatter.

impl Default for ImageMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImageMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ImageMetadata

fn eq(&self, other: &ImageMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ImageMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
