A raster or vector graphic.

\n

You can wrap the image in a figure to give it a number and caption.

\n

Like most elements, images are block-level by default and thus do not\nintegrate themselves into adjacent paragraphs. To force an image to become\ninline, put it into a box.

\n

Example

\n
#figure(\n  image("molecular.jpg", width: 80%),\n  caption: [\n    A step in the molecular testing\n    pipeline of our lab.\n  ],\n)\n

A path to an image file or raw bytes making up an\nimage in one of the supported formats.

\n

Bytes can be used to specify raw pixel data in a row-major,\nleft-to-right, top-to-bottom format.

","example":"
#let original = read("diagram.svg")\n#let changed = original.replace(\n  "#2B80FF", // blue\n  green.to-hex(),\n)\n\n#image(bytes(original))\n#image(bytes(changed))\n

The image's format.

\n

By default, the format is detected automatically. Typically, you thus\nonly need to specify this when providing raw bytes as the\nsource (even then, Typst will try to figure out the\nformat automatically, but that's not always possible).

\n

Supported formats are "png", "jpg", "gif", "svg" as well\nas raw pixel data. Embedding PDFs as images is\nnot currently supported.

\n

When providing raw pixel data as the source, you must specify a\ndictionary with the following keys as the format:

\n\n

The pixel width multiplied by the height multiplied by the channel count\nfor the specified encoding must then match the source data.

","example":"
#image(\n  read(\n    "tetrahedron.svg",\n    encoding: none,\n  ),\n  format: "svg",\n  width: 2cm,\n)\n\n#image(\n  bytes(range(16).map(x => x * 16)),\n  format: (\n    encoding: "luma8",\n    width: 4,\n    height: 4,\n  ),\n  width: 2cm,\n)\n
