Items of a Processing Pipeline

In G'MIC, an image processing pipeline is described as a sequence of items separated by the space character. Such items are interpreted and executed from the left to the right. For instance, the expression:

filename.jpg blur 3,0 sharpen 10 resize 200%,200% output file_out.jpg

defines a valid pipeline composed of nine G'MIC items.

Each G'MIC item is either a command, a list of command arguments, a filename or a special input string.

Escape characters '' and double quotes " can be used to define items containing spaces or other special characters. For instance, the two strings single\ item and "single item" both define the same single item, with a space in it.
