View Source API Reference image v0.54.4

Image is based upon the fabulous vix library that provides a libvips wrapper for Elixir.

Functions to define and validate the band formats of an image.

Functions to define and validate the blending modes that can be applied when composing images.

BlurHash is an algorithm developed by Wolt that allows encoding of an image into a compact string representation called a blurhash. This string can then be decoded back into an image, providing a low-resolution placeholder that can be displayed quickly while the actual image is being loaded.

Implements image classification functions using Axon machine learning models managed by Bumblebee.

Functions to manage image color and color conversion.

Functions to define and validate the combine modes that can be applied when composing images.

Functions to draw directly on a mutable image.

Functions to extract and interpret image EXIF data.

Defines the known modes by which an image can be extended.

Implements image generation functions using Axon machine learning models managed by Bumblebee.

A histogram is a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value. By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance.

Defines the known color interpretations to which an image can be converted to and from.

Defines the known resampling kernels to which an image can be converted to and from.
