Managing Presentation Properties in Ruby

Aspose.Slides - Accessing Built-in Properties

To access Built-in properties of presentation using Aspose.Slides Java for Ruby, simply invoke get_properties method of Properties module. Here you can see example code.

Ruby Code

 def get_properties()

    data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'



    # Instantiate the Presentation class that represents the presentation

    pres = Rjb::import('com.aspose.slides.Presentation').new(data_dir + "HelloWorld.pptx")

    # Create a reference to IDocumentProperties object associated with Presentation

    dp = pres.getDocumentProperties()

    # Display the builtin properties

    puts "Category : " + dp.getCategory().to_s

    puts "Current Status : " + dp.getContentStatus().to_s

    puts "Creation Date : " + dp.getCreatedTime().to_string

    puts "Author : " + dp.getAuthor().to_s

    puts "Description : " + dp.getComments().to_s

    puts "KeyWords : " + dp.getKeywords().to_s

    puts "Last Modified By : " + dp.getLastSavedBy().to_s

    puts "Supervisor : " + dp.getManager().to_s

    puts "Modified Date : " + dp.getLastSavedTime().to_string

    puts "Presentation Format : " + dp.getPresentationFormat().to_s

    puts "Last Print Date : " + dp.getLastPrinted().to_string

    puts "Is Shared between producers : " + dp.getSharedDoc().to_s

    puts "Subject : " + dp.getSubject().to_s

    puts "Title : " + dp.getTitle().to_s

end

Aspose.Slides - Modifying Built-in Properties

To update Built-in properties of presentation using Aspose.Slides Java for Ruby, call update_properties method of Properties module. Here you can see example code.

Ruby Code

 def update_properties()

    data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'



    # Instantiate the Presentation class that represents the presentation

    pres = Rjb::import('com.aspose.slides.Presentation').new(data_dir + "HelloWorld.pptx")

    # Create a reference to IDocumentProperties object associated with Presentation

    dp = pres.getDocumentProperties()

    # Set the builtin 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

    save_format = Rjb::import('com.aspose.slides.SaveFormat')

    pres.save(data_dir + "DocProps.pptx", save_format.Pptx)

    puts "Properties have been updated, Please check output file."

end   

Aspose.Slides - Adding Custom Document Properties

To add custom property of document using Aspose.Slides Java for Ruby, call add_custom_properties method of Properties module. Here you can see example code.

Ruby Code

 def add_custom_properties()

    data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'



    # Instantiate the Presentation class that represents the presentation

    pres = Rjb::import('com.aspose.slides.Presentation').new(data_dir + "HelloWorld.pptx")

    # Getting Document Properties

    dp = pres.getDocumentProperties()

    # Adding Custom properties

    dp.set_Item("New Custom" , 12)

    dp.set_Item("My Name","Mudassir")

    dp.set_Item("Custom", 124)

    # Saving presentation

    save_format = Rjb::import('com.aspose.slides.SaveFormat')

    pres.save(data_dir + "CustomDemo.pptx",save_format.Pptx)

    puts "Added custom properties, please check output file."

end   

Aspose.Slides - Removing Document Properties

To add custom property of document using Aspose.Slides Java for Ruby, call remove_property method of Properties module. Here you can see example code.

Ruby Code

 def remove_property()

    data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'



    # Instantiate the Presentation class that represents the presentation

    pres = Rjb::import('com.aspose.slides.Presentation').new(data_dir + "HelloWorld.pptx")

    # Getting Document Properties

    dp = pres.getDocumentProperties()

    # Getting property name at particular index

    property_name = dp.getPropertyName(2)

    # Removing selected property

    dp.remove(property_name)

    # Saving presentation

    save_format = Rjb::import('com.aspose.slides.SaveFormat')

    pres.save(data_dir + "RemoveDP.pptx",save_format.Pptx)

    puts "Remove document property, please check output file."
