How to Convert CGM to PNG

Python developers can easily load & convert CGM files to PNG in just a few lines of code.

  1. Define the paths to the input PDF file and output directory using path.join() function.
  2. Create a new instance of the CgmLoadOptions class from aspose.pdf library to define options for loading the input PDF document.
  3. Use the Document class from aspose.pdf library to open and load the input PDF file, passing the input file path and CgmLoadOptions instance. This step loads the entire PDF document into memory.
  4. Specify the resolution for converting images using the Resolution property of the PngDevice class, setting it to 300 dots per inch (DPI). This controls the quality and size of the output image.
  5. Create a new instance of the PngDevice class from aspose.pdf library to convert specific pages from the input PDF document to PNG images. The device is used to generate the output image file.
  6. Open an in-memory file stream using FileIO to write the generated PNG image to disk, specifying a binary write mode and creating a writable file object.
  7. Use the process() method of the PngDevice instance to convert a specific page from the input PDF document to a PNG image, writing it to the output stream.
  8. Close the output stream to free up system resources and prevent data leaks. This ensures that the file is properly flushed and written to disk.
  9. Print a success message indicating that the input PDF file has been successfully converted into an image file, typically with a file extension such as .png or .jpg.

Here is an example that demonstrates how to convert CGM to PNG in Python. You can follow these easy steps to convert your CGM file to PNG format. First, upload your CGM file and then simply save it as a PNG file. You can use fully qualified filenames for both CGM reading and PNG writing. The output PNG content and formatting will be identical to the original CGM document.

Example: Convert CGM to PNG via Python

This sample code shows CGM to PNG Python Conversion

Input file:

File not added

Output format:

PNG

Output file:

import aspose.pdf as apdf
from io import FileIO
from os import path
# The path to the documents directory
path_infile = path.join(indir, infile)
path_outfile = path.join(outDir, outfile)

options = apdf.CgmLoadOptions()

# Open PDF document
document = apdf.Document(path_infile, options)
resolution = apdf.devices.Resolution(300)

device = apdf.devices.PngDevice(resolution)

# Create file for save
image_stream = FileIO(path_outfile, "w")
# Convert a particular page and save the image to stream
device.process(document.pages[1], image_stream)
# Close stream
image_stream.close()
print(infile + " converted into " + outfile)
