Today we will use our convert API to easily change the DPI of an image file. Let’s begin by installing the client using pip installer.

pip install git+https://github.com/Cloudmersive/Cloudmersive.APIClient.Python.Convert.git

All that’s left is to call convert_image_image_set_dpi and input the image file and specify the desired DPI:

from __future__ import print_function
import time
import cloudmersive_convert_api_client
from cloudmersive_convert_api_client.rest import ApiException
from pprint import pprint# Configure API key authorization: Apikey
configuration = cloudmersive_convert_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'# create an instance of the API class
api_instance = cloudmersive_convert_api_client.ConvertImageApi(cloudmersive_convert_api_client.ApiClient(configuration))
dpi = 56 # int | New DPI in pixels-per-inch, for example 300 DPI or 600 DPI
input_file = '/path/to/file' # file | Input file to perform the operation on.try:
    # Change image DPI
    api_response = api_instance.convert_image_image_set_dpi(dpi, input_file)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling ConvertImageApi->convert_image_image_set_dpi: %s\n" % e)

And it’s really just that simple.
