To learn more about Aspose.PDF for Python via .NET and explore the basic requirements and features of the library, check out the following Aspose.PDF for Python via .NET Documentation pages for other use cases.

Create a PDF file from scratch in Python

In the next code snippet, we are creating a PDF document fron scratch containing the text “Hello World!”. After installing Aspose.PDF for Python via .NET in your environment, you can execute below code sample to see how Aspose.PDF API works.

Below code snippet follows these steps:

1. Instantiate a Document object.
2. Add a Page to the document object.
3. Create a TextFragment object.
4. Add TextFragment to Paragraph collection of the page.
5. Save the resultant PDF document.

The following code snippet is a “Hello, World!” program to exhibit working of Aspose.PDF for Python via .NET API:

import aspose.pdf as ap

# Initialize document object
document = ap.Document()
# Add page
page = document.pages.add()
# Initialize textfragment object
text_fragment = ap.text.TextFragment("Hello,world!")
# Add text fragment to new page
page.paragraphs.add(text_fragment)
# Save updated PDF
document.save("output.pdf")

Example of converting HTML to PDF

Aspose.PDF for Python via .NET is a PDF manipulation API that lets you convert any existing HTML documents to PDF format. The process of converting HTML to PDF can be flexibly customized.

Below code snippet follows these steps:

1. Create an instance of the HtmlLoadOptions object.
2. Initialize Document object.
3. Save output PDF document by calling Document.Save() method.

import aspose.pdf as ap
# Instantiate an object of HtmlLoadOptions
options = ap.HtmlLoadOptions()
# Convert HTML to PDF
document = ap.Document("input.html", options)
# Save PDF
document.save("output.pdf")

Example of converting PDF to SVG

Aspose.PDF for Python via .NET supports the feature to convert SVG image to PDF format. To accomplish this requirement, the SvgSaveOptions class has been introduced into the Aspose.PDF namespace. Instantiate an object of SvgSaveOptions and pass it as a second argument to the Document.Save(..) method.

Below code snippet follows these steps:

1. Create an object of the Document class.
2. Create SvgSaveOptions object with needed settings.
3. Call the Document.Save() method and pass it SvgSaveOptions object convert the PDF document to SVG.

import aspose.pdf as ap

# Open PDF document
document = ap.Document("input.pdf")

# Instantiate an object of SvgSaveOptions
saveOptions = ap.SvgSaveOptions()

# Do not compress SVG image to Zip archive
saveOptions.compress_output_to_zip_archive = False
saveOptions.treat_target_file_name_as_directory = True

# Save the output in SVG files
document.save("output.svg", saveOptions)

Merge PDF Files

Merge multiple PDF into single file in Python with Aspose.PDF programmatically. PDF files are merged such that the first one is joined at the end of the other document.

Below code snippet follows these steps:

1. Open first document.
2. Open second document.
3. Add pages of second document to the first.
4. Save concatenated output file.

import aspose.pdf as ap

# Open first document
document1 = ap.Document("input_1.pdf")
# Open second document
document2 = ap.Document("input_2.pdf")

# Add pages of second document to the first
document1.pages.add(document2.pages)

# Save concatenated output file
document1.save("output.pdf")

Print PDF to XPS printer

You can print a PDF file to an XPS printer, or some other soft printer for that matter, using the PdfViewer class.

Below code snippet follows these steps:

1. Create an object of the PdfViewer class.
2. Open the PDF file using the bind_pdf method.
3. Set different print settings using the PrinterSettings and PageSettings classes.
4. Set the printer_name property to the XPS or other printer.
5. Print document using the print_document_with_settings method.

import aspose.pdf as ap
import aspose.pydrawing as drawing

# Create PdfViewer object
viewer = ap.facades.PdfViewer()

# Open input PDF file
viewer.bind_pdf("input.pdf")

# Set attributes for printing
# Print the file with adjusted size
viewer.auto_resize = True
# Print the file with adjusted rotation
viewer.auto_rotate = True
# Do not produce the page number dialog when printing
viewer.print_page_dialog = False

# Create objects for printer and page settings
ps = ap.printing.PrinterSettings()
pgs = ap.printing.PageSettings()

# Set XPS/PDF printer name
ps.printer_name = "Microsoft XPS Document Writer"
# Or set the PDF printer
# ps.printer_name = "Adobe PDF"

# Set PageSize(if required)
pgs.paper_size = ap.printing.PaperSize("A4", 827, 1169)

# Set PageMargins(if required)
pgs.margins = ap.devices.Margins(0, 0, 0, 0)

# Print document using printer and page settings
viewer.print_document_with_settings(pgs, ps)

# Close the PDF file after printing
viewer.close()
