Ruby 代码
# The path to the documents directory.
data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'
# Create PDF document
pdf_document = Rjb::import('com.aspose.pdf.Document').new(data_dir + 'input1.pdf')
# get page collection
page_collection = pdf_document.getPages()
# get particular page
pdf_page = page_collection.get_Item(1)
#get page properties
