Enum ndk::bitmap::BitmapCompressFormat

#[non_exhaustive]
#[repr(i32)]
pub enum BitmapCompressFormat {
    Jpeg = 0,
    Png = 1,
    WebPLossy = 3,
    WebPLossless = 4,
}

Available on crate features bitmap and api-level-30 only.

Specifies the formats that can be compressed to with Bitmap::compress() and Bitmap::compress_raw().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Jpeg = 0

Compress to the JPEG format.

quality of 0 means compress for the smallest size. 100 means compress for max visual quality.

Png = 1

Compress to the PNG format.

PNG is lossless, so quality is ignored.

WebPLossy = 3

Compress to the WEBP lossless format.

quality refers to how much effort to put into compression. A value of 0 means to compress quickly, resulting in a relatively large file size. 100 means to spend more time compressing, resulting in a smaller file.

WebPLossless = 4

Compress to the WEBP lossy format.

quality of 0 means compress for the smallest size. 100 means compress for max visual quality.

Trait Implementations

impl Clone for BitmapCompressFormat

fn clone(&self) -> BitmapCompressFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BitmapCompressFormat

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

Formats the value using the given formatter.

impl From<BitmapCompressFormat> for i32

fn from(enum_value: BitmapCompressFormat) -> Self

Converts to this type from the input type.

impl From<i32> for BitmapCompressFormat

fn from(number: i32) -> Self

Converts to this type from the input type.

impl FromPrimitive for BitmapCompressFormat

type Primitive = i32

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for BitmapCompressFormat

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 PartialEq for BitmapCompressFormat

fn eq(&self, other: &BitmapCompressFormat) -> 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.
