abstract protected ImageToolkitOperationBase::execute(array $arguments) Performs the actual manipulation on the image. Image toolkit operation implementers must implement this method. This method is responsible for actually performing the operation on the image. When this method gets called, the implementer may assume all arguments, also the optional ones, to be available, validated and corrected. Parameters array $arguments: An associative array of arguments to be used by the toolkit operatio

abstract protected ImageToolkitOperationBase::arguments() Returns the definition of the operation arguments. Image toolkit operation implementers must implement this method to "document" their operation, thus also if no arguments are expected. Return value array An array whose keys are the names of the arguments (e.g. "width", "degrees") and each value is an associative array having the following keys: description: A string with the argument description. This is used only internally for docum

public final ImageToolkitOperationBase::apply(array $arguments) Applies a toolkit specific operation to an image. Parameters array $arguments: An associative array of data to be used by the toolkit operation. Return value bool TRUE if the operation was performed successfully, FALSE otherwise. Throws \InvalidArgumentException If one or more of the arguments are not valid.

The plugin ID. There are no strict requirements as to the string to be used to identify the plugin, since discovery of the appropriate operation plugin to be used to apply an operation is based on the values of the 'toolkit' and the 'operation' annotation values. However, it is recommended that the following patterns be used: '{toolkit}_{operation}' for the first implementation of an operation by a toolkit. '{module}_{toolkit}_{operation}' for overrides of existing implementations supplied by a
