FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Usage

The Color package contains a separate class per color format, which each implement a Color interface.

There are seven classes which implement the Color interface:

interface Spatie\Color\Color

fromString(): Color

Parses a color string and returns a Color implementation, depending on the format of the input string.

Throws an InvalidColorValue exception if the string can't be parsed.

Rgb, Rgba, Hsl and Hsla strings are allowed to have spaces. rgb(0,0,0) is just as valid as rgb(0, 0, 0).

red(): int|string

Return the value of the red color channel.

green(): int|string

Return the value of the green color channel.

blue(): int|string

Return the value of the blue color channel.

toCmyk(): Cmyk

Convert a color to a Cmyk color.

toHex(): Hex

Convert a color to a Hex color.

When coming from a color format that doesn't support opacity, it can be added by passing it to the $alpha parameter.

toHsb(): Hsb

Convert a color to a Hsb color.

toHsl(): Hsl

Convert a color to a Hsl color.

When coming from a color format that supports opacity, the opacity will simply be omitted.

toHsla(float $alpha = 1): Hsla

Convert a color to a Hsla color.

When coming from a color format that doesn't support opacity, it can be added by passing it to the $alpha parameter.

toRgb(): Rgb

Convert a color to an Rgb color.

When coming from a color format that supports opacity, the opacity will simply be omitted.

toRgba(float $alpha = 1): Rgba

Convert a color to a Rgba color.

When coming from a color format that doesn't support opacity, it can be added by passing it to the $alpha parameter.

__toString(): string

Cast the color to a string.

Factory::fromString(): Color

With the Factory class, you can create a color instance from any string (it does an educated guess under the hood). If the string isn't a valid color string in any format, it throws an InvalidColorValue exception.
