PPTX to JPG using cURL Commands

Another way to convert PowerPoint slides to images is by calling Aspose.Slides Cloud API using cURL commands. With cURL, you can send HTTP requests directly from the command line, making it an easy and convenient method. Now, first we need to generate an authentication token by sending a request to the token endpoint with your App SID and App Key.

Please execute the following command to generate the accessToken.

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=ee170169-ca49-49a4-87b7-0e2ff815ea6e&client_secret=7f098199230fc5f2175d494d48f2077c" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Once the accessToken is generated, please execute the following command to convert the slide number 4 and 8 of the PowerPoint to JPG format.

curl -v "https://api.aspose.cloud/v3.0/slides/{sourceFile}/Jpeg?slides=4%2C8" \
-X POST \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer {accessToken}" \
-H  "Content-Type: application/json" \
-d "{  \"DefaultRegularFont\": \"string\",  \"FontFallbackRules\": [    {      \"RangeStartIndex\": 0,      \"RangeEndIndex\": 0,      \"FallbackFontList\": [        \"string\"      ]    }  ],  \"FontSubstRules\": [    {      \"SourceFont\": \"string\",      \"TargetFont\": \"string\",      \"NotFoundOnly\": true    }  ]}" \
-o "{resultantZIP}"

Replace {sourceFile} with the name of input PowerPoint presentation in Cloud storage, {accessToken} with JWT access token generated above and, {resultantZIP} with the name of resultant file to be generated on specified drive location.
