| title: Loading of external resources containing by a document | ||
| weight: 5 | ||
| keywords: set timeout, Groupdocs.Viewer | ||
| description: "This article explains how to manage loading of external resources contained by a document with GroupDocs.Viewer within your Java applications." | ||
| productName: GroupDocs.Viewer for Java | ||
| hideChildren: False | ||
| --- | ||
|
|
||
| If the document contains external resources, such as images, GroupDocs.Viewer loads them when rendering a document. This allows the document to display correctly, but is a potential security risk. | ||
|
|
||
| GroupDocs.Viewer allows you to manage loading of external resources contained by a document. These features are supported for the following formats: | ||
| - [Word Processing File Formats](https://docs.fileformat.com/word-processing/) | ||
| - [Web File Formats](https://docs.fileformat.com/web/) | ||
| - [SpreadSheet File Formats](https://docs.fileformat.com/spreadsheet/) | ||
|
|
||
| Use the [LoadOptions](https://reference.groupdocs.com/viewer/java/com.groupdocs.viewer.options/loadoptions/) object to manage loading of external resources. | ||
|
|
||
| ## Skip loading of external resources | ||
|
|
||
| The following code snippet shows how to deny loading of external resources: | ||
|
|
||
| {{< tabs "example3">}} | ||
| {{< tab "Java" >}} | ||
| ```java | ||
| LoadOptions loadOptions = new LoadOptions(); | ||
| loadOptions.setSkipExternalResources(true); // Skip loading of external resources | ||
|
|
||
| try (Viewer viewer = new Viewer("business-flyer.docx", loadOptions)) { | ||
| HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources(); | ||
|
|
||
| viewer.view(viewOptions); | ||
| } | ||
| ``` | ||
| {{< /tab >}} | ||
| {{< tab "Kotlin">}} | ||
| ```kotlin | ||
| val loadOptions = LoadOptions() | ||
| loadOptions.isSkipExternalResources = true // Skip loading of external resources | ||
|
|
||
| Viewer("business-flyer.docx", loadOptions).use { viewer -> | ||
| val viewOptions = HtmlViewOptions.forEmbeddedResources() | ||
|
|
||
| viewer.view(viewOptions) | ||
| } | ||
| ``` | ||
| {{< /tab >}} | ||
| {{< /tabs >}} | ||
|
|
||
| The following images show the output file with and without external resources (see top right corner): | ||
|
|
||
| | loadOptions.setSkipExternalResources(false) | loadOptions.setSkipExternalResources(true) | | ||
| |-----------------------------------------------------------|-------------------------------------------------------------| | ||
| |  |  | | ||
|
|
||
| ## Manage a safelist for loading external resources | ||
|
|
||
| The following code snippet shows how to allow loading of external resources from specific URLs: | ||
|
|
||
| {{< tabs "example2">}} | ||
| {{< tab "Java" >}} | ||
| ```java | ||
| LoadOptions loadOptions = new LoadOptions(); | ||
| loadOptions.setSkipExternalResources(true); // Skip loading of all external resources | ||
| loadOptions.getWhitelistedResources().add("avatars.githubusercontent.com"); // Enable loading of external resources that has `avatars.githubusercontent.com` fragment in resource URL. | ||
|
|
||
| try (Viewer viewer = new Viewer("business-flyer.docx", loadOptions)) { | ||
| HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources(); | ||
| viewer.view(viewOptions); | ||
| } | ||
| ``` | ||
| {{< /tab >}} | ||
| {{< tab "Kotlin">}} | ||
| ```kotlin | ||
| val loadOptions = LoadOptions() | ||
| loadOptions.isSkipExternalResources = true // Skip loading of all external resources | ||
| loadOptions.whitelistedResources.add("avatars.githubusercontent.com") // Enable loading of external resources that has `avatars.githubusercontent.com` fragment in resource URL. | ||
|
|
||
| val viewer = Viewer("business-flyer.docx", loadOptions) | ||
| val viewOptions = HtmlViewOptions.forEmbeddedResources() | ||
| viewer.use { | ||
| it.view(viewOptions) | ||
| } | ||
| ``` | ||
| {{< /tab >}} | ||
| {{< /tabs >}} | ||
|
|
||
| ## Set timeout for loading of external resources | ||
|
|
||
| The default timeout is 10 seconds. GroupDocs.Viewer allows you to change this value. | ||
|
|
||
| The following code snippet shows how to set a timeout to load external resources: | ||
|
|
||
| {{< tabs "example1">}} | ||
| {{< tab "Java" >}} | ||
| ```java | ||
| // Specify a timeout. | ||
| LoadOptions loadOptions = new LoadOptions(); | ||
| loadOptions.setResourceLoadingTimeout(5000); | ||
| // Render a file. | ||
| try (Viewer viewer = new Viewer("sample.docx", loadOptions)) { | ||
| HtmlViewOptions viewOptions = HtmlViewOptions.forEmbeddedResources(); | ||
| viewer.view(viewOptions); | ||
| } | ||
| ``` | ||
| {{< /tab >}} | ||
| {{< tab "Kotlin">}} | ||
| ```kotlin | ||
| // Specify a timeout. | ||
| val loadOptions = LoadOptions() | ||
| loadOptions.setResourceLoadingTimeout(5000) | ||
| // Render a file. | ||
| Viewer("sample.docx", loadOptions).use { viewer -> | ||
| val viewOptions = HtmlViewOptions.forEmbeddedResources() | ||
| viewer.view(viewOptions) | ||
| } | ||
|
|
||
| ``` | ||

| --- | ||
| GroupDocs.Viewer allows you to optimize the output PDF file for a web browser or to reduce the file size by optimizing resources. | ||
|
|
||
| Optimization for a web allows a browser to display the first pages of a PDF file when you open the document, instead of waiting for the entire file to download. | ||
|
|
||
| Resource optimization allows you to reduce the size of the output PDF file. While optimizing, GroupDocs.Viewer may reduce the image size or quality, remove notes or form fields, remove objects, fonts, or personal information from a document, and so on. | ||
|
|
||
| You can also optimize an existing PDF file. To do this, open it, specify the optimization parameters, and save the output file. | ||
