## Master class

Contains elements that define a master for the document. A master is a shape on a stencil that you use repeatedly to create drawings. When you drag a shape from a stencil onto the drawing page, the shape becomes an instance of that master, and a local copy of the master is included in the document.

```js
new Master()
```

Constructor.

### deepClone() {#deepclone}

Creates deep copy of this instance.

**Returns:** Object — `Object`

### dispose() {#dispose}

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

### getAlignName() {#getalignname}

Specifies whether the master's text in the stencil window is aligned left, right, or center. The value of the property is AlignNameValue integer constant.

### getBaseID() {#getbaseid}

A GUID (globally unique identifier) that identifies the master across documents.

### getConnects() {#getconnects}

Contains a Connect element for each connection between two shapes in a drawing.

### getHidden() {#gethidden}

Specifies whether the master is hidden in the user interface. The value of the property is BOOL integer constant.

### getIcon() {#geticon}

Specifies a MIME (Multipurpose Internet Mail Extensions) encoded binary icon (in .ico format) for a Master or MasterShortcut element in a document.

**Example:**

```js
var aspose = aspose || {};
aspose.diagram = require("aspose.diagram");
fs = require("fs");
stencil = new aspose.diagram.Diagram("Timeline.vss");
// get master
master = stencil.getMasters().getMasterByName("Diamond milestone");
// get byte array
bytes = master.getIcon();
// create an image file and write byte array to the image
fs.writeFileSync("out-MasterIcon.png", bytes);
```

### getIconSize() {#geticonsize}

The size of the element's icon. The value of the property is IconSizeValue integer constant.

### getIconUpdate() {#geticonupdate}

Specifies whether the icon is automatically generated from the master itself. The value of the property is BOOL integer constant.

### getID() {#getid}

The unique ID of the element within its parent element.

### getMatchByName() {#getmatchbyname}

The MatchByName attribute determines how Microsoft Visio decides if a document master is already present when an instance of a master is dropped on the drawing page. It allows changes made to a document master to apply to new instances of the master, even if the instances are dragged from a stand-alone stencil file. The value of the property is BOOL integer constant.

### getName() {#getname}

The name of the element.

### getNameU() {#getnameu}

The universal name of the element.

### getPageSheet() {#getpagesheet}

Contains elements that define the page sheet for a Page or Master element.

### getPatternFlags() {#getpatternflags}

The PatternFlags attribute determines whether a master behaves as a custom pattern.

### getPrompt() {#getprompt}

The status bar and tool tip prompt for the element.

### getShapes() {#getshapes}

Collection of Shape objects.

### getUniqueID() {#getuniqueid}

A GUID that identifies the master within the document.

### setAlignName() {#setalignname}

Specifies whether the master's text in the stencil window is aligned left, right, or center. The value of the property is AlignNameValue integer constant.

### setHidden() {#sethidden}

Specifies whether the master is hidden in the user interface. The value of the property is BOOL integer constant.

### setIcon() {#seticon}

Specifies a MIME (Multipurpose Internet Mail Extensions) encoded binary icon (in .ico format) for a Master or MasterShortcut element in a document.

**Example:**

```js
var aspose = aspose || {};
aspose.diagram = require("aspose.diagram");
fs = require("fs");
stencil = new aspose.diagram.Diagram("Timeline.vss");
// get master
master = stencil.getMasters().getMasterByName("Diamond milestone");
// get byte array
bytes = master.getIcon();
// create an image file and write byte array to the image
fs.writeFileSync("out-MasterIcon.png", bytes);
```

### setIconSize() {#seticonsize}

The size of the element's icon. The value of the property is IconSizeValue integer constant.

### setIconUpdate() {#seticonupdate}

Specifies whether the icon is automatically generated from the master itself. The value of the property is BOOL integer constant.

### setID() {#setid}

The unique ID of the element within its parent element.

### setMatchByName() {#setmatchbyname}

The MatchByName attribute determines how Microsoft Visio decides if a document master is already present when an instance of a master is dropped on the drawing page. It allows changes made to a document master to apply to new instances of the master, even if the instances are dragged from a stand-alone stencil file. The value of the property is BOOL integer constant.

### setName() {#setname}

The name of the element.

### setNameU() {#setnameu}
