Expand description
A generalized pixel.
A pixel object is usually not used standalone but as a view into an image buffer.
Required Associated Types§
Required Associated Constants§
sourceconst CHANNEL_COUNT: u8
const CHANNEL_COUNT: u8
The number of channels of this pixel type.
sourceconst COLOR_MODEL: &'static str
const COLOR_MODEL: &'static str
A string that can help to interpret the meaning each channel See gimp babl.
Required Methods§
sourcefn channels_mut(&mut self) -> &mut [Self::Subpixel]
fn channels_mut(&mut self) -> &mut [Self::Subpixel]
Returns the components as a mutable slice
sourcefn channels4(
&self,
) -> (Self::Subpixel, Self::Subpixel, Self::Subpixel, Self::Subpixel)
👎Deprecated since 0.24.0: Use channels()
or channels_mut()
fn channels4( &self, ) -> (Self::Subpixel, Self::Subpixel, Self::Subpixel, Self::Subpixel)
channels()
or channels_mut()
Returns the channels of this pixel as a 4 tuple. If the pixel has less than 4 channels the remainder is filled with the maximum value
sourcefn from_channels(
a: Self::Subpixel,
b: Self::Subpixel,
c: Self::Subpixel,
d: Self::Subpixel,
) -> Self
👎Deprecated since 0.24.0: Use the constructor of the pixel, for example Rgba([r,g,b,a])
or Pixel::from_slice
fn from_channels( a: Self::Subpixel, b: Self::Subpixel, c: Self::Subpixel, d: Self::Subpixel, ) -> Self
Rgba([r,g,b,a])
or Pixel::from_slice
Construct a pixel from the 4 channels a, b, c and d. If the pixel does not contain 4 channels the extra are ignored.
sourcefn from_slice(slice: &[Self::Subpixel]) -> &Self
fn from_slice(slice: &[Self::Subpixel]) -> &Self
Returns a view into a slice.
Note: The slice length is not checked on creation. Thus the caller has to ensure that the slice is long enough to prevent panics if the pixel is used later on.
sourcefn from_slice_mut(slice: &mut [Self::Subpixel]) -> &mut Self
fn from_slice_mut(slice: &mut [Self::Subpixel]) -> &mut Self
Returns mutable view into a mutable slice.
Note: The slice length is not checked on creation. Thus the caller has to ensure that the slice is long enough to prevent panics if the pixel is used later on.
sourcefn to_luma_alpha(&self) -> LumaA<Self::Subpixel>
fn to_luma_alpha(&self) -> LumaA<Self::Subpixel>
Convert this pixel to luma with an alpha channel
sourcefn map_with_alpha<F, G>(&self, f: F, g: G) -> Self
fn map_with_alpha<F, G>(&self, f: F, g: G) -> Self
Apply the function f
to each channel except the alpha channel.
Apply the function g
to the alpha channel.
sourcefn apply_with_alpha<F, G>(&mut self, f: F, g: G)
fn apply_with_alpha<F, G>(&mut self, f: F, g: G)
Apply the function f
to each channel except the alpha channel.
Apply the function g
to the alpha channel. Works in-place.
sourcefn map2<F>(&self, other: &Self, f: F) -> Self
fn map2<F>(&self, other: &Self, f: F) -> Self
Apply the function f
to each channel of this pixel and
other
pairwise.
Provided Methods§
sourcefn map_without_alpha<F>(&self, f: F) -> Self
fn map_without_alpha<F>(&self, f: F) -> Self
Apply the function f
to each channel except the alpha channel.
sourcefn apply_without_alpha<F>(&mut self, f: F)
fn apply_without_alpha<F>(&mut self, f: F)
Apply the function f
to each channel except the alpha channel.
Works in place.
