How to convert a PDF to PNG array in Salesforce Apex

Today’s article is going to tackle how to perform file format conversion between PDFs and PNG arrays. Through the use of one of our handy APIs, this is going to be a snap.

First step, download our Document/Conversion client here. Then extract its contents into your Apex project’s folder.

We shall proceed by invoking the convertDocumentPdfToPngArray function:

SwagConvertDocumentApi api = new SwagConvertDocumentApi();
SwagClient client = api.getClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) client.getAuthentication('Apikey');
Apikey.setApiKey('YOUR API KEY');
Map<String, Object> params = new Map<String, Object>{
'inputFile' => Blob.valueOf('Sample text file\nContents')
};
try {
// cross your fingers
SwagPdfToPngResult result = api.convertDocumentPdfToPngArray(params);
System.debug(result);
} catch (Swagger.ApiException e) {
// ...handle your exceptions
}

That’s it! We will be returned a list of URLs that correspond to each PNG image in the array.
