| setMaxImportSize($size) X-Ref |
| Set the maximum size if files to be imported. Files larger than this size (in kB) will not be imported into the CSS. Importing files into the CSS as data-uri will save you some connections, but we should only import relatively small decorative images so that our CSS file doesn't get too bulky. param: int $size Size in kB |

| Set the type of extensions to be imported into the CSS (to save network connections). Keys of the array should be the file extensions & respective values should be the data type. param: string[] $extensions Array of file extensions |

| Move any import statements to the top. return: string param: string $content Nearly finished CSS content |
| combineImports($source, $content, $parents) X-Ref |
| Combine CSS from import statements. return: string param: string $source The file to combine imports for param: string $content The CSS content to combine imports for param: string[] $parents Parent paths, for circular reference checks |

| execute($path = null, $parents = array() X-Ref |
| Minify the data. Perform CSS optimizations. return: string The minified data param: string[optional] $path Path to write the data to param: string[] $parents Parent paths, for circular reference checks |
| move(ConverterInterface $converter, $content) X-Ref |
| Moving a css file should update all relative urls. Relative references (e.g. ../images/image.gif) in a certain css file, will have to be updated when a file is being saved at another location (e.g. ../../images/image.gif, if the new CSS file is 1 folder deeper). return: string param: ConverterInterface $converter Relative path converter param: string $content The CSS content to update relative urls for |
| shortenColors($content) X-Ref |
| Shorthand hex color codes. #FF0000 -> #F00. return: string param: string $content The CSS content to shorten the hex color codes for |
| shortenFontWeights($content) X-Ref |

| Replace all occurrences of functions that may contain math, where whitespace around operators needs to be preserved (e.g. calc, clamp) |
| extractCustomProperties() X-Ref |
| Replace custom properties, whose values may be used in scenarios where we wouldn't want them to be minified (e.g. inside calc) |
| canImportBySize($path) X-Ref |
| No description |
| canImportByPath($path) X-Ref |
| Check if file a file can be imported, going by the path. return: bool param: string $path |
| getPathConverter($source, $target) X-Ref |
