Replaces all colors by their absolute value.

Add `src_channel` from `other` multiplied by `scale` to `dst_channel` of this surface. If channels are not the same length, this returns [`SurfaceErro

Returns a iterator over all instructions.

Returns a mut iterator over all instructions.

Returns the [`AlphaMode`] of this surface. This is for output headers, e.g. for usage in [`Context::output_header`]. It does not affect calculations.

Returns the approximate fraction (0 to 1) of the image with an alpha value greater than `alpha_ref`. This function uses 8 x 8 subsampling together wi

Computes an average value for the given channel over the entire sphere. This takes solid angles into account when producing an average per steradian,

Sets values in the given channel to either 1 or 0 depending on if they're greater than the `threshold`, with optional `dithering`. If dither is true,

Interpolates all texels between their current color and a constant color `(r, g, b, a)`. `t` is the value used for linearly interpolating between the

Stores per-block YCoCg scaling information for potentially better 4-channel compression of YCoCg data. For each 4x4 block, this computes the maximum

Returns the default [`Resize::Box`] filter, with `width = 0.5`.

Resizes this surface to create the next mip in a mipmap chain. Returns false iff the next mip would have been smaller than `min_size` (signaling the

Replaces this surface with a surface the size of the next mip in a mip chain (half the width and height), but with each channel cleared to a constant

Get a device builder.

Returns whether the surface would have a next mip in a mip chain with minimum size `min_size`. That is, it returns false if this surface has size `1x

Crops or expands this surface from the `(0, 0, 0)` corner, with any new values cleared to 0. # Panics Panics if any of `w`, `h`, or `d` are `0`. #

Raises the given channel to the power `gamma`.

Raises the given channel to the power `1/gamma`.

Alias to `clamped`, which doesn't take `self`. # Panics Panics if `lower` is greater than `upper`. Swap the values yourself if necessary.

Alias to `clamped01`, which doesn't take `self`.

Alias to `clamped_minus1_1`, which doesn't take `self`.

Alias to `clamp`, which accepts a `RangeInclusive` parameter instead of two values.

Constrains this value to be between -1 and 1 (inclusive).

Alias to `clamped`, which accepts a `RangeInclusive` parameter instead of two values.

Compress the [`CubeSurface`] and write the compressed data to a `Vec<u8>`. Returns `Some(Vec<u8>)` on success.

Compress and write data to a `Vec<u8>`. Returns `Some(Vec<u8>)` on success. # Panics Panics if `w * h * d < rgba.len()`.

Convert a module from the data representation into structured representation.

Similar to [`Surface::convolve_slice()`], this convolves a channel with a kernel. Values should be specified in row-major order.

Convolves a channel with a kernel. This uses a 2D `dim x dim` kernel, with values in `kernel` specified in row-major order. The behavior around image

Copies the bounding box `src` of `other` to the bounding box `dst` of this surface. # Panics Panics if `src` and `dst` are not the same shape, or on

Copy `src_channel` from `other` to `dst_channel` of this surface. If channels are not the same length, this returns [`SurfaceError::InvalidDimensions`

Spherically convolves this [`CubeSurface`] with a `max(0.0f, cos(theta))^cosinePower` kernel, returning a [`CubeSurface`] with faces with dimension `s

Returns the number of mips that would be in a full mipmap chain starting with this [`CubeSurface`] For instance, a full mip chain for a cube map with

Returns the number of mipmaps in a mipmap chain, stopping when [`Surface::can_make_next_mipmap()`] returns false. That is, it stops when a `1x1x1` mi

Creates a sub image from the subset `bounds` of this surface. # Panics Panics if this surface does not contain `bounds`.
