## Properties[](#properties-1)

### `Optional`content[](#content)

content?: \[number, number, number, number\]

If `icon-text-fit` is used in a layer with this image, this option defines the part of the image that can be covered by the content in `text-field`.

### pixelRatio[](#pixelratio)

pixelRatio: number

The ratio of pixels in the image to physical pixels on the screen

### sdf[](#sdf)

sdf: boolean

Whether the image should be interpreted as an SDF image

### `Optional`stretchX[](#stretchx)

stretchX?: \[number, number\]\[\]

### `Optional`stretchY[](#stretchy)

stretchY?: \[number, number\]\[\]

If `icon-text-fit` is used in a layer with this image, this option defines the part(s) of the image that can be stretched vertically.

### `Optional`textFitHeight[](#textfitheight)

textFitHeight?: [TextFit](https://docs.maptiler.com/sdk-js/api-reference/enums/TextFit/)
