## **Introduction**

Aspose.Slides supports two types of document properties: **Built-in** and **Custom**. Both of these property types can easily be accessed and managed using the Aspose.Slides API.

Aspose.Slides allows you to work with presentation document properties through the [IDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/idocumentproperties/) interface. An instance of this interface is returned by the [Presentation.getDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/presentation/#getDocumentProperties--) method. The following examples show how to read, modify, and manage these properties.

Please note that the **Application** and **AppVersion** fields cannot be modified. Aspose.Slides rewrites them on every save, so a saved presentation always reports "Aspose.Slides for Java" and the version of the library that produced it. Any value passed to `setNameOfApplication` is discarded when the presentation is written.

## **Document Properties in PowerPoint**

Microsoft PowerPoint 2007 allows managing the document properties of the presentation files. All you have to do is to click the Office icon and further **Prepare | Properties | Advanced Properties** menu item of the Microsoft PowerPoint 2007 as shown below:

|**Selecting Advanced Properties menu item**|** |
| :- | :- |
|![todo:image_alt_text](https://i.imgur.com/ZrmuCD6.jpg)| |
After you select **Advanced Properties** menu item, a dialog would appear allowing you to manage the document properties of the PowerPoint file as shown below in the figure:

|**Properties Dialog**|** |

|![todo:image_alt_text](https://i.imgur.com/LibmdQd.jpg)| |
In the above **Properties Dialog**, you can see that there are many tab pages like **General**, **Summary**, **Statistics**, **Contents** and **Custom**. All these tab pages allow configuring different kinds of information related to the PowerPoint files. **Custom** tab is used to manage the custom properties of the PowerPoint files.

Working with Document Properties Using Aspose.Slides for Java

As we have described earlier that Aspose.Slides for Java supports two kinds of document properties, which are **Built-in** and **Custom** properties. So, developers can access both kinds of properties with the use of Aspose.Slides for Java API. Aspose.Slides for Java provides a class [IDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/idocumentproperties) that represents the document properties associated with a presentation file through **Presentation.DocumentProperties** property.

Developers can use **IDocumentProperties** property exposed by [Presentation](https://reference.aspose.com/slides/java/com.aspose.slides/presentation) object to access the document properties of the presentation files as described below:

## **Access Built-in Properties**

These properties as exposed by [IDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/idocumentproperties) object include: **Creator** (Author), **Description**, **Keywords** **Created** (Creation Date), **Modified** Modification Date, **Printed** Last Print Date, **LastModifiedBy**, **Keywords**, **SharedDoc** (Is shared between different producers?), **PresentationFormat**, **Subject** and **Title**

```java
import com.aspose.slides.*;

// Instantiate the Presentation class that represents the presentation
Presentation pres = new Presentation("Presentation.pptx");
try {
    // Create a reference to IDocumentProperties object associated with Presentation
    IDocumentProperties dp = pres.getDocumentProperties();
    
    // Display the built-in properties
    System.out.println("Category : " + dp.getCategory());
    System.out.println("Current Status : " + dp.getContentStatus());
    System.out.println("Creation Date : " + dp.getCreatedTime());
    System.out.println("Author : " + dp.getAuthor());
    System.out.println("Description : " + dp.getComments());
    System.out.println("KeyWords : " + dp.getKeywords());
    System.out.println("Last Modified By : " + dp.getLastSavedBy());
    System.out.println("Supervisor : " + dp.getManager());
    System.out.println("Modified Date : " + dp.getLastSavedTime());
    System.out.println("Presentation Format : " + dp.getPresentationFormat());
    System.out.println("Last Print Date : " + dp.getLastPrinted());
    System.out.println("Is Shared between producers : " + dp.getSharedDoc());
    System.out.println("Subject : " + dp.getSubject());
    System.out.println("Title : " + dp.getTitle());
} finally {
    if (pres != null) pres.dispose();
}
```

## **Modify Built-in Properties**

Modifying the built-in properties of presentation files is as easy as that of accessing them. You can simply assign a string value to any desired property and the property value would be modified. In the example given below, we have demonstrated how we can modify the built-in document properties of the presentation file using Aspose.Slides for Java.

```java
import com.aspose.slides.*;

Presentation pres = new Presentation("Presentation.pptx");
try {
    // Create a reference to IDocumentProperties object associated with Presentation
    IDocumentProperties dp = pres.getDocumentProperties();
    
    // Set the built-in properties
    dp.setAuthor("Aspose.Slides for Java");
    dp.setTitle("Modifying Presentation Properties");
    dp.setSubject("Aspose Subject");
    dp.setComments("Aspose Description");
    dp.setManager("Aspose Manager");
    
    // Save your presentation to a file
    pres.save("DocProps.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

This example modifies the built-in properties of the presentation that can be viewed as shown below:

## **Add Custom Document Properties**

Aspose.Slides for Java also allows developers to add the custom the values for presentation Document properties. The example below adds three custom properties, then looks up the name stored at index 2 and removes that property, so the saved presentation keeps two of them. Custom properties are indexed in alphabetical order, not in the order they were added.

```java
import com.aspose.slides.*;

Presentation pres = new Presentation();
try {
    // Getting Document Properties
    IDocumentProperties dProps = pres.getDocumentProperties();
    
    // Adding Custom properties
    dProps.set_Item("New Custom", 12);
    dProps.set_Item("My Name", "Mudassir");
    dProps.set_Item("Custom", 124);
    
    // Getting property name at particular index
    String getPropertyName = dProps.getCustomPropertyName(2);
    
    // Removing selected property
    dProps.removeCustomProperty(getPropertyName);
    
    // Saving presentation
    pres.save("CustomDemo.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

## **Access and Modify Custom Properties**

Aspose.Slides for Java also allows developers to access the values of custom properties. An example is given below that shows how can you access and modify all of these custom properties for a presentation.

```java
import com.aspose.slides.*;

Presentation pres = new Presentation("Presentation.pptx");
try {
    // Create a reference to DocumentProperties object associated with Presentation
    IDocumentProperties dp = pres.getDocumentProperties();
    
    // Access and modify custom properties
    for (int i = 0; i < dp.getCountOfCustomProperties(); i++) {
        // Display names and values of custom properties
        System.out.println("Custom Property Name : " + dp.getCustomPropertyName(i));
        System.out.println("Custom Property Value : " + dp.get_Item(dp.getCustomPropertyName(i)));
    
        // Modify values of custom properties
        dp.set_Item(dp.getCustomPropertyName(i), "New Value " + (i + 1));
    }
    
    // Save your presentation to a file
    pres.save("CustomDemoModified.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
}
```

This example modifies the custom properties of the [PPTX ](https://docs.fileformat.com/presentation/pptx/)presentation. Following figures show the presentation custom properties before and after modification:

## **Advanced Document Properties**

{{% alert color="info" %}} 

New methods [ReadDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo#readDocumentProperties--), [UpdateDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo#updateDocumentProperties-com.aspose.slides.IDocumentProperties-), and [WriteBindedPresentation](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo#writeBindedPresentation-java.lang.String-) have been added to [IPresentationInfo](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo), logic of the [IDocumentProperties.setLastSavedTime](https://reference.aspose.com/slides/java/com.aspose.slides/idocumentproperties#setLastSavedTime-java.util.Date-) property setter has been changed.

{{% /alert %}} 

The two new methods [ReadDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo#readDocumentProperties--) and [UpdateDocumentProperties](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo#updateDocumentProperties-com.aspose.slides.IDocumentProperties-) have been added to [IPresentationInfo](https://reference.aspose.com/slides/java/com.aspose.slides/IPresentationInfo) interface. They provide quick access to document properties and allow to change and update properties without loading a whole presentation.

The typical scenario load the properties, change some value and update the document can be implemented in the following way:

```java
import com.aspose.slides.*;

// read the info of presentation
IPresentationInfo info = PresentationFactory.getInstance().getPresentationInfo("presentation.pptx");

// obtain the current properties
IDocumentProperties props = info.readDocumentProperties();

// set the new values of Author and Title fields
props.setAuthor("New Author");
props.setTitle("New Title");

// update the presentation with a new values
info.updateDocumentProperties(props);
info.writeBindedPresentation("presentation.pptx");
```

There is another way to use properties of a particular presentation as a template to update properties in other presentations:

```java
import com.aspose.slides.*;

IPresentationInfo info = PresentationFactory.getInstance().getPresentationInfo("template.pptx");
DocumentProperties template = (DocumentProperties) info.readDocumentProperties();

template.setAuthor("Template Author");
template.setTitle("Template Title");
template.setCategory("Template Category");
template.setKeywords("Keyword1, Keyword2, Keyword3");
template.setCompany("Our Company");
template.setComments("Created from template");
template.setContentType("Template Content");
template.setSubject("Template Subject");

for (String path : new String[] { "doc1.pptx", "doc2.odp", "doc3.ppt" }) {
    IPresentationInfo toUpdate = PresentationFactory.getInstance().getPresentationInfo(path);
    toUpdate.updateDocumentProperties(template);
    toUpdate.writeBindedPresentation(path);
}
```

```java
import com.aspose.slides.*;

private static void updateByTemplate(String path, IDocumentProperties template) 
{
    IPresentationInfo toUpdate = PresentationFactory.getInstance().getPresentationInfo(path);
    toUpdate.updateDocumentProperties(template);
    toUpdate.writeBindedPresentation(path);
}
```

A new template can be created from scratch and then used to update multiple presentations:

```java
import com.aspose.slides.*;

DocumentProperties template = new DocumentProperties();

template.setAuthor("Template Author");
template.setTitle("Template Title");
template.setCategory("Template Category");
template.setKeywords("Keyword1, Keyword2, Keyword3");
template.setCompany("Our Company");
template.setComments("Created from template");
template.setContentType("Template Content");
template.setSubject("Template Subject");

for (String path : new String[] { "doc1.pptx", "doc2.odp", "doc3.ppt" }) {
    IPresentationInfo toUpdate = PresentationFactory.getInstance().getPresentationInfo(path);
    toUpdate.updateDocumentProperties(template);
    toUpdate.writeBindedPresentation(path);
}
```

## **Set Proofing Language**

Aspose.Slides provides the LanguageId property (exposed by the PortionFormat class) to allow you to set the proofing language for a PowerPoint document. The proofing language is the language for which spellings and grammar in the PowerPoint are checked.

This Java code shows you how to set the proofing language for a PowerPoint:

```java
import com.aspose.slides.*;

String pptxFileName = "presentation.pptx";

Presentation pres = new Presentation(pptxFileName);
try {
    AutoShape autoShape = (AutoShape)pres.getSlides().get_Item(0).getShapes().get_Item(0);

    IParagraph paragraph = autoShape.getTextFrame().getParagraphs().get_Item(0);
    paragraph.getPortions().clear();

    Portion newPortion = new Portion();

    IFontData font = new FontData("SimSun");
    IPortionFormat portionFormat = newPortion.getPortionFormat();
    portionFormat.setComplexScriptFont(font);
    portionFormat.setEastAsianFont(font);
    portionFormat.setLatinFont(font);

    portionFormat.setLanguageId("zh-CN"); // set the Id of a proofing language

    newPortion.setText("1。");
    paragraph.getPortions().add(newPortion);
} finally {
    if (pres != null) pres.dispose();
}
```

## **Set Default Language**

This Java code shows you how to set the default language for an entire PowerPoint presentation:

```java
import com.aspose.slides.*;

LoadOptions loadOptions = new LoadOptions();
loadOptions.setDefaultTextLanguage("en-US");

Presentation pres = new Presentation(loadOptions);
try {
    // Adds a new rectangle shape with text
    IAutoShape shp = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 150, 50);
    shp.getTextFrame().setText("New Text");

    // Checks the first portion language
    System.out.println(shp.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().getLanguageId());
} finally {
    if (pres != null) pres.dispose();
}
```

## ***FAQ**

### How can I remove a built-in property from a presentation?

Built-in properties are an integral part of the presentation and cannot be removed entirely. However, you can either change their values or set them to empty if allowed by the specific property.

### What happens if I add a custom property that already exists?

If you add a custom property that already exists, its existing value will be overwritten with the new one. You do not need to remove or check the property beforehand, as Aspose.Slides automatically updates the property's value.

### Can I access presentation properties without fully loading the presentation?

Yes, you can access presentation properties without fully loading the presentation by using the `getPresentationInfo` method from the [PresentationFactory](https://reference.aspose.com/slides/java/com.aspose.slides/presentationfactory/) class. Then, utilize the `readDocumentProperties` method provided by the [IPresentationInfo](https://reference.aspose.com/slides/java/com.aspose.slides/ipresentationinfo/) interface to read the properties efficiently, saving memory and improving performance.
