## README

# PostCSS Image Function [<img src="https://postcss.github.io/postcss/logo.svg" alt="PostCSS Logo" width="90" height="90" align="right">][PostCSS]

`npm install @csstools/postcss-image-function --save-dev`

[PostCSS Image Function] lets you easily generate a solid-color image from any color following the [CSS Images 4 Specification].

```css
.foo {
	background-image: image(transparent);
}

.foo {
	--bg-image: image(transparent);
}

/* becomes */

.foo {
	background-image: linear-gradient(transparent,transparent);
}

.foo {
	--bg-image: linear-gradient(transparent,transparent);
}
```

## Usage

Add [PostCSS Image Function] to your project:

```bash
npm install postcss @csstools/postcss-image-function --save-dev
```

Use it as a [PostCSS] plugin:

```js
const postcss = require('postcss');
const postcssImageFunction = require('@csstools/postcss-image-function');

postcss([
	postcssImageFunction(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
```



## Options

### preserve

The `preserve` option determines whether the original notation
is preserved. By default, it is not preserved.

```js
postcssImageFunction({ preserve: true })
```

```css
.foo {
	background-image: image(transparent);
}

.foo {
	--bg-image: image(transparent);
}

/* becomes */

.foo {
	background-image: linear-gradient(transparent,transparent);
	background-image: image(transparent);
}

.foo {
	--bg-image: linear-gradient(transparent,transparent);
}

@supports (background-image: image(red)) {
.foo {
	--bg-image: image(transparent);
}
}
```
