PresentationSecurityLoadingLimits Class

Specifies limits for presentation loading.

Declaration

public class PresentationSecurityLoadingLimits extends SecurityLoadingLimits

Remarks

Use the LoadOptions.getSecurityLoadingLimits() method to access the PresentationSecurityLoadingLimits object and configure limits before you load the presentation.

The following security loading limits are available:

Maximum presentation file size.
Maximum number of XML elements.
Maximum XML element nesting depth.
Maximum number of slides.
Maximum number of shapes per slide.

The following code snippet configures loading options, handles security violations, and loads a presentation with the specified security settings. The example throws an exception if the presentation exceeds a configured limit or contains restricted content, and logs the violation to the console:

package presentation;

import com.devexpress.docs.office.*;
import com.devexpress.docs.presentation.*;

import java.io.*;

public class Main {
    public static void main(String[] args) throws Exception {

        // Create load options.
        LoadOptions loadOptions = new LoadOptions();

        // Configure security loading limits.
        PresentationSecurityLoadingLimits limits = new PresentationSecurityLoadingLimits();
        limits.setMaxFileSize(50L * 1024 * 1024);
        limits.setMaxSlideCount(100);
        limits.setMaxShapeCountPerSlide(500);

        loadOptions.setSecurityLoadingLimits(limits);

        // Configure security loading options.
        PresentationSecurityLoadingOptions securityLoadingOptionsOptions = new PresentationSecurityLoadingOptions();
        securityLoadingOptionsOptions.setRemoveMacros(true);
        securityLoadingOptionsOptions.setRemoveOleObjects(true);
        securityLoadingOptionsOptions.setRemoveActiveXContent(true);
        securityLoadingOptionsOptions.setRemoveCustomXMLParts(true);

        loadOptions.setSecurityLoadingOptions(securityLoadingOptionsOptions);

        // Handle security loading violations.
        loadOptions.setSecurityLoadingHandler(new ISecurityLoadingHandler() {
            @Override
            public SecurityLimitAction handleLimitExceeded(
                    SecurityLimitExceededParams parameters) {

                System.out.println("Security limit exceeded: " + parameters.getPropertyName());
                return SecurityLimitAction.THROW;
            }

            @Override
            public SecurityViolationAction handleOptionsViolation(
                    SecurityOptionsViolationParams parameters) {

                System.out.println("Security option violated: " + parameters.getPropertyName());
                return SecurityViolationAction.REMOVE;
            }
        });

        try(FileInputStream inputStream = new FileInputStream("Presentation.pptx");
            Presentation presentation = new Presentation(inputStream, loadOptions)) {

            //...
        }
    }
}
