### 2.3. Finestra di dialogo tracciati

The «Paths» dialog is used to manage paths, allowing you to create or delete them, save them, convert them to and from selections, etc. Please see Sezione 4, « Tracciati » for more information about paths.

Figura 15.10. Il pannello «tracciati»

#### 2.3.1. Attivazione della finestra

Questa finestra di dialogo è di tipo agganciabile; vedere la sezione sulle Finestre agganciabili per le istruzioni su come gestire questo tipo di finestre.

È accessibile:

- From the main menu, as Windows → Dockable Dialogs → Paths.

- From the Tab menu in any dockable dialog by clicking on and selecting Add Tab → Paths.

In the Windows menu, there is a list of detached windows which exists only if at least one dialog remains open. In this case, you can raise the «Paths» dialog from the main menu: Windows → Paths.

#### 2.3.2. Using the Paths Dialog

Panoramica

  This dialog shows a list of all paths present in the current image. For each path you can set their attributes, as explained below, and perform certain actions using the buttons at the bottom of the dialog, or using the context menu.

  In multi-window mode, you can show the name of the active image at the top of the dock by choosing «Show Image Selection» from the Tab menu. This allows you to see at a glance to which image the paths you are working on belong.

  Se la lista non è vuota, in ogni momento uno degli elementi è il tracciato attivo dell'immagine, quello che è soggetto a qualsiasi operazione venga eseguita usando il menu della finestra o i pulsanti in fondo ad essa: il tracciato attivo viene evidenziato nella lista. Facendo clic su uno degli elementi della lista lo si rende il canale attivo.

  Right-clicking on any entry in the list brings up the Paths Menu. You can also access the Paths Menu from the dialog Tab menu.

Selecting multiple paths

  GIMP allows you to select multiple paths and perform actions on them, like stroking or filling. Selecting multiple paths is done by using the mouse and Shift key, for adding a range of paths, or Ctrl key, for adding or removing the clicked path.

Path list header

  Directly above the list of paths is the header bar. On the left you see the icons that identify the visibility and lock columns. In the middle a text label will tell you how many paths are currently selected if it is more than one.

Path attributes

  Every path is shown in the list with its own attributes, which are very similar to the layer attributes:

  Visibilità del tracciato

    By default, paths are not visible. This icon is shown when the path is visible. Clicking this toggles between visible and invisible. When a path is «visible», a border is drawn over each path segment on the image display. This does not change the actual pixel data of the image. Shift-clicking on the icon causes all other paths to be hidden.

  Path lock attributes

    Each path has lock attributes. If one of its attributes is set, the respective lock icon will show up in front of the thumbnail.

    When multiple attributes are set, a double lock icon will show here. Clicking in this column allows you to change these attributes.

    Lock path

      This icon shows when «lock path» is enabled for the current path. When this is enabled, the path is locked for any action that changes it, meaning there will be no changes done to this path. Clicking the icon toggles between enabled and disabled.

    Blocca posizione e dimensioni

      This icon shows when «lock path position» is enabled for the current path. When this is enabled, the path is locked for any action that changes its position. Clicking the icon toggles between enabled and disabled.

    Lock visibility

      This toggle button controls the «Lock» setting for the visibility of the path. If this is enabled, the path visibility cannot be changed until you disable the lock.

  Miniatura

    A small preview icon represents the effect of the path. This preview can be enlarged by holding down the left mouse button on it. If you drag the thumbnail into the Layers dialog, it will create a new layer with a rasterized copy of the path.

  nome del tracciato

    Il nome del tracciato, che deve essere univoco all'interno dell'immagine. Facendo un doppio clic sul nome sarà possibile modificarlo. Se il nome impostato esiste già, gli verrà aggiunto un numero (ad es. «#1») per renderlo univoco.

Managing paths

  The button bar at the bottom offers the following functionality:

  These buttons correspond to entries in the context menu (accessed by right-clicking on an entry in the list), but some of them have extra options obtainable by holding down modifier keys while pressing the button.

  Nuovo tracciato

    Vedere Nuovo tracciato. Tenendo premuto il tasto Maiusc si crea un nuovo tracciato (vuoto) con gli ultimi valori usati, senza aprire la finestra di dialogo Nuovo tracciato.

  Raise Paths

    See Raise Paths. Holding down Shift moves the selected paths to the top of the list.

  Lower Paths

    See Lower Paths. Holding down Shift moves the selected paths to the bottom of the list.

  Duplicate Paths

    See Duplicate Paths.

  Paths to Selection

    Converts paths into a selection; see Paths to Selection for a full explanation. You can use modifier keys to set the way the new selection interacts with the existing selection:

    Tasto modificatore | Azione
    --- | ---
    Nessuno | Sostituisce la selezione esistente
    Maiusc | Aggiunge alla selezione
    Ctrl | Sottrae dalla selezione
    Maiusc+Ctrl | Interseca con la selezione.

  Selezione a tracciato

    Shift-clicking this button brings up the Advanced Settings dialog that allows you to adjust how the selection is converted to a path.

  Paint along the paths

    See Stroke Paths. Holding down Shift strokes the paths based on the last used values without opening the Stroke Paths dialog.

  Delete Paths

    Delete Paths deletes the currently selected paths.

#### 2.3.3. Il menu contestuale dei «tracciati»

Il menu dei tracciati si può richiamare facendo clic con il tasto destro su un elemento della lista nella finestra dei tracciati, oppure scegliendo la prima voce ("Menu tracciati") dal menu della scheda dei tracciati. Questo menu fornisce l'accesso alla maggior parte delle operazioni che influenzano i tracciati.

Modifica tracciato

  Modifica tracciato rappresenta un modo alternativo di attivare l'omonimo strumento tracciato, usato per creare e manipolare i tracciati. Può essere attivato anche dalla barra degli strumenti, oppure usando la scorciatoia da tastiera B (N.d.T. per Bezier).

Modificare gli attributi del tracciato

  Modifica attributi tracciato richiama una piccola finestra che permette di modificare il nome del tracciato. È possibile fare ciò anche facendo un doppio clic sul nome nella lista all'interno della finestra dei tracciati.

Color Tags

  Color Tags brings up a sub menu, similar to the one in the Layers Dialog, that allows you to select a color tag for the selected paths.

Nuovo tracciato

  New Path creates a new path, adds it to the list in the Paths dialog, and makes it the active path for the image. It brings up a dialog that allows you to give a name to the path. The new path is created with no anchor points, so you will need to use the Path tool to give it some before you can use it for anything.

Raise Paths

  Raise Paths moves the selected paths one slot higher in the list in the Paths dialog.

  The position of a path in the list has no functional significance, so this is simply a convenience to help you keep things organized.

Lower Paths

  Lower Paths moves the selected paths one slot lower in the list in the Paths dialog.

  The position of a path in the list has no functional significance, so this is simply a convenience to help you keep things organized.

Duplicate Paths

  Duplicate Paths creates a copy of the selected paths, assigns unique names, adds them to the list in the Paths dialog, and makes them the selected paths for the image. The copies will be visible only if the original paths were visible.

Delete Paths

  Delete Paths deletes the currently selected paths.

Fondi tracciati visibili

  Fondi tracciati visibili prende tutti i tracciati dell'immagine che sono visibili (cioè quelli vicino ai quali nella finestra dei tracciati è visualizzata l'icona con l'occhio), e li trasforma nei componenti di un unico tracciato. Questo può essere utili se si vuole delinearli allo stesso modo, ecc.

Paths to Selection, Add Paths to Selection, Subtract Paths from Selection, Intersect Paths with Selection

  These commands all convert the active paths into a selection, and then combine it with the existing selection in the specified ways. (Paths to Selection discards the existing selection and replaces it with one formed from the path.) If necessary, any unclosed components of the path are closed by connecting the last anchor point to the first anchor point with a straight line. The «marching ants» for the resulting selection should closely follow the path, but don't expect the correspondence to be perfect.

Selezione a tracciato

  Si può accedere a questa operazione in diversi modi:

  - From the main menu, as Select → To Path

  - Dal menu della finestra dei tracciati, con Selezione a tracciato.

  - From the Selection to Path button at the bottom of the Paths dialog.

  Selection to Path creates a new path from the image's selection. In most cases the resulting path will closely follow the «marching ants» of the selection, but the correspondence will not usually be perfect.

  Converting a two-dimensional selection mask into a one-dimensional path involves some rather tricky algorithms: you can alter the way it is done using the Advanced Options, which are accessed by holding down the Shift key while pressing the Selection to Path button at the bottom of the Paths dialog. This brings up the Advanced Settings dialog, which allows you to set a lot of different options. In general, Selection to Path will do what you expect it to, without the need to adjust the advanced settings.

Fill Paths

  Si può accedere a questa operazione in diversi modi:

  - From the main menu, as Edit → Fill Paths…

  - From the Paths dialog menu, as Fill Paths….

  - From the Fill Paths button in the Tool Options for the Paths tool.

  Fill Paths fills all areas delimited by the selected paths with the current foreground color or currently selected pattern. See the section about Fill Paths for more information.

Stroke Paths…

  Si può accedere a questa operazione in diversi modi:

  - From the main menu, as Edit → Stroke Paths…

  - From the Paths dialog menu, as Stroke Paths….

  - From the Paint along the path button at the bottom of the Paths dialog.

  - From the Stroke Paths button in the Tool Options for the Paths tool.

  Stroke Paths renders the selected paths on the active layer of the image, permitting a wide variety of line styles and stroking options. See the sections about Stroke Paths and Stroking for more information.

Copy Paths

  Copy Paths copies the selected paths to the Paths Clipboard, enabling you to paste it into a different image.

  | Suggerimento
  You can also copy and paste paths by dragging their icon from the Paths dialog into the target image's display.

  | Nota
  Quando si copia un tracciato in un'immagine, esso non è visibile. È necessario renderlo visibile tramite la finestra di dialogo tracciati.

Incolla tracciato

  Paste Path creates a new path from the contents of the Path Clipboard, adds it to the list in the Paths dialog, and makes it the active path for the image. If no path has previously been copied into the clipboard, the menu entry will be disabled.

Export Paths

  Export Paths… allows you to save a path to a file: it pops up a file save dialog that allows you to specify the file name and location. You can later add this path to any GIMP image using the Import Path command. The format used for saving paths is SVG: this means that vector-graphics programs such as Inkscape will also be able to import the paths you save. See the Paths section for more information on SVG files and how they relate to GIMP paths.

Importa tracciato

  Import Path… creates a new path from an SVG file: it pops up a file chooser dialog that allows you to navigate to the file. See the Paths section for information on SVG files and how they relate to GIMP paths.
