在 Ruby 中更新页面尺寸

Aspose.PDF - 更新页面尺寸

要使用 Aspose.PDF Java for Ruby 更新页面尺寸，只需调用 UpdatePageDimensions 模块。

Ruby 代码

# The path to the documents directory.

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

# Open the target document

pdf = Rjb::import('com.aspose.pdf.Document').new(data_dir + 'input1.pdf')

# get page collection

page_collection = pdf.getPages()

# get particular page

pdf_page = page_collection.get_Item(1)

# set the page size as A4 (11.7 x 8.3 in) and in Aspose.PDF, 1 inch = 72 points

# so A4 dimensions in points will be (842.4, 597.6)

pdf_page.setPageSize(597.6,842.4)

# save the newly generated PDF file

pdf.save(data_dir + "output.pdf")

puts "Dimensions updated successfully!"
