Python Images to PDF Conversions

Aspose.PDF for Python via .NET allows you to convert different formats of images to PDF files. Our library demonstrates code snippets for converting the most popular image formats, such as - BMP, CGM, DICOM, EMF, JPG, PNG, SVG and TIFF formats.

Convert BMP to PDF

Convert BMP files to PDF document using Aspose.PDF for Python via .NET library.

BMP images are Files having extension. BMP represent Bitmap Image files that are used to store bitmap digital images. These images are independent of graphics adapter and are also called device independent bitmap (DIB) file format.

You can convert BMP to PDF files with Aspose.PDF for Python via .NET API. Therefore, you can follow the following steps to convert BMP images:

Steps to Convert BMP to PDF in Python:

  1. Create a new PDF Document
  2. Define Image Placement
  3. Insert the Image into the PDF
  4. Save the PDF file

So the following code snippet follows these steps and shows how to convert BMP to PDF using Python:


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    document = apdf.Document()
    page = document.pages.add()
    rectangle = apdf.Rectangle(0, 0, 595, 842, True)  # A4 size in points
    page.add_image(path_infile, rectangle)
    document.save(path_outfile)

Convert CGM to PDF

CGM is a file extension for a Computer Graphics Metafile format commonly used in CAD (computer-aided design) and presentation graphics applications. CGM is a vector graphics format that supports three different encoding methods: binary (best for program read speed), character-based (produces the smallest file size and allows for faster data transfers) or cleartext encoding (allows users to read and modify the file with a text editor).

Check next code snippet for converting CGM files to PDF format.

Steps to Convert CGM to PDF in Python:

  1. Define File Paths
  2. Set Load Options for CGM.
  3. Convert CGM to PDF
  4. Print Conversion Message

    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    # The path to the documents directory
    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    options = apdf.CgmLoadOptions()

    # Open PDF document
    document = apdf.Document(path_infile, options)
    document.save(path_outfile)
    print(infile + " converted into " + outfile)

Convert DICOM to PDF

DICOM format is the medical industry standard for the creation, storage, transmission, and visualization of digital medical images and documents of examined patients.

Aspose.PDF for Python allows you to convert DICOM and SVG images, but for technical reasons to add images you need to specify the type of file to be added to PDF.

The following code snippet shows how to convert DICOM files to PDF format with Aspose.PDF. You should load DICOM image, place the image on a page in a PDF file and save the output as PDF.


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    # Load the DICOM file
    dicom_file = pydicom.dcmread(path_infile)

    # Get the dimensions of the image
    rows = dicom_file.Rows
    columns = dicom_file.Columns

    # Print the dimensions
    print(f"DICOM image size: {rows} x {columns} pixels")

    # Initialize new Document
    document = apdf.Document()
    page = document.pages.add()
    image = apdf.Image()
    image.file_type = apdf.ImageFileType.DICOM
    image.file = path_infile

    # Set page dimensions

    page.page_info.height = rows
    page.page_info.width = columns
    page.page_info.margin.bottom = 0
    page.page_info.margin.top = 0
    page.page_info.margin.right = 0
    page.page_info.margin.left = 0
    page.paragraphs.add(image)

    document.save(path_outfile)
    print(infile + " converted into " + outfile)

Convert EMF to PDF

EMF stores graphical images device-independently. Metafiles of EMF comprises of variable-length records in chronological order that can render the stored image after parsing on any output device.

The following code snippet shows how to convert an EMF to PDF with Python:


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom
    
    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    document = apdf.Document()
    page = document.pages.add()
    rectangle = apdf.Rectangle(0, 0, 595, 842, True)  # A4 size in points
    # add image to new pdf page
    page.add_image(path_infile, rectangle)

    # Save the file into PDF format
    document.save(path_outfile)
    print(infile + " converted into " + outfile)

Convert GIF to PDF

Convert GIF files to PDF document using Aspose.PDF for Python via .NET library.

GIF is able to store compressed data without loss of quality in a format of no more than 256 colors. The hardware-independent GIF format was developed in 1987 (GIF87a) by CompuServe for transmitting bitmap images over networks.

So the following code snippet follows these steps and shows how to convert BMP to PDF using Python:


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    document = apdf.Document()
    page = document.pages.add()
    rectangle = apdf.Rectangle(0, 0, 595, 842, True)  # A4 size in points
    page.add_image(path_infile, rectangle)

    document.save(path_outfile)
    print(infile + " converted into " + outfile)

Convert PNG to PDF

    document.save(path_outfile)

    print(infile + " converted into " + outfile)

Convert SVG to PDF

Aspose.PDF for Python via .NET explains how to convert SVG images to PDF format and how to get dimensions of the source SVG file.

Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for two-dimensional vector graphics, both static and dynamic (interactive or animated). The SVG specification is an open standard that has been under development by the World Wide Web Consortium (W3C) since 1999.

SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and if required, compressed. As XML files, SVG images can be created and edited with any text editor, but it is often more convenient to create them with drawing programs such as Inkscape.

The following code snippet shows the process of converting SVG file into PDF format with Aspose.PDF for Python.


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    load_options = apdf.SvgLoadOptions()
    document = apdf.Document(path_infile, load_options)
    document.save(path_outfile)

    print(infile + " converted into " + outfile)

Convert TIFF to PDF

Aspose.PDF file format supported, be it a single frame or multi-frame TIFF image. It means that you can convert the TIFF image to PDF.

TIFF or TIF, Tagged Image File Format, represents raster images that are meant for usage on a variety of devices that comply with this file format standard. TIFF image can contain several frames with different images. Aspose.PDF file format is also supported, be it a single frame or multi-frame TIFF image.

You can convert TIFF to PDF in the same manner as the rest raster file formats graphics:


    import aspose.pdf as apdf
    from io import FileIO
    from os import path
    import pydicom

    path_infile = path.join(self.dataDir, infile)
    path_outfile = path.join(self.dataDir, "python", outfile)

    document = apdf.Document()
    page = document.pages.add()
    rectangle = apdf.Rectangle(0, 0, 595, 842, True)  # A4 size in points
    page.add_image(path_infile, rectangle)
    document.save(path_outfile)

    print(infile + " converted into " + outfile)
