imageElement
Question mark

A raster or vector graphic.

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

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

Example

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

Parameters
Question mark

source
str or bytes
RequiredPositional
Question mark

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

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

View example
#let original = read("diagram.svg")
#let changed = original.replace(
  "#2B80FF", // blue
  green.to-hex(),
)

#image(bytes(original))
#image(bytes(changed))

format
auto or str or dictionary
Settable
Question mark

The image's format.

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

Supported formats are "png", "jpg", "gif", "svg" as well as raw pixel data. Embedding PDFs as images is not currently supported.

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

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

VariantDetails
"png"

Raster format for illustrations and transparent graphics.

"jpg"

Lossy raster format suitable for photos.

"gif"

Raster format that is typically used for short animated clips. Typst can load GIFs, but they will become static.

"svg"

The vector graphics format of the web.

Default: auto

View example
#image(
  read(
    "tetrahedron.svg",
    encoding: none,
  ),
  format: "svg",
  width: 2cm,
)

#image(
  bytes(range(16).map(x => x * 16)),
  format: (
    encoding: "luma8",
    width: 4,
    height: 4,
  ),
  width: 2cm,
)

width
auto or relative
Settable
Question mark

The width of the image.

Default: auto

height
auto or relative or fraction
Settable
Question mark

The height of the image.

Default: auto

alt
none or str
Settable
Question mark

A text describing the image.

Default: none

fit
str
Settable
Question mark

How the image should adjust itself to a given area (the area is defined by the width and height fields). Note that fit doesn't visually change anything if the area's aspect ratio is the same as the image's one.

VariantDetails
"cover"

The image should completely cover the area (preserves aspect ratio by cropping the image only horizontally or vertically). This is the default.

"contain"

The image should be fully contained in the area (preserves aspect ratio; doesn't crop the image; one dimension can be narrower than specified).

"stretch"

The image should be stretched so that it exactly fills the area, even if this means that the image will be distorted (doesn't preserve aspect ratio and doesn't crop the image).

Default: "cover"

View example
#set page(width: 300pt, height: 50pt, margin: 10pt)
#image("tiger.jpg", width: 100%, fit: "cover")
#image("tiger.jpg", width: 100%, fit: "contain")
#image("tiger.jpg", width: 100%, fit: "stretch")

scaling
auto or str
Settable
Question mark

A hint to viewers how they should scale the image.

When set to auto, the default is left up to the viewer. For PNG export, Typst will default to smooth scaling, like most PDF and SVG viewers.

Note: The exact look may differ across PDF viewers.

VariantDetails
"smooth"

Scale with a smoothing algorithm such as bilinear interpolation.

"pixelated"

Scale with nearest neighbor or a similar algorithm to preserve the pixelated look of the image.

Default: auto

icc
auto or str or bytes
Settable
Question mark

An ICC profile for the image.

ICC profiles define how to interpret the colors in an image. When set to auto, Typst will try to extract an ICC profile from the image.

Default: auto

Warning
