How to Convert WMF to PDF with Java REST API

This short tutorial shows you how to convert WMF to PDF with Java REST API. WMF (Windows Metafile) is a graphics file format used for storing vector graphics and bitmap images. It was developed by Microsoft and is commonly used for clipart, logos, and other types of graphical images. WMF files are often used in Windows applications, such as Microsoft Word and PowerPoint.

Whereas, PDF (Portable Document Format) is a file format developed by Adobe Systems for document exchange. PDFs are used to present and exchange documents reliably, independent of software, hardware, or operating system. PDFs contain text, images, and other information, which are all combined into one file that can be shared across multiple devices. If you would like WMF to PDF Conversion in Java Low Code API then the same can be performed with the help of the following code.

Prerequisite

Steps to Convert WMF to PDF in Java REST API

  1. Set Client ID and Client Secret for the API
  2. Create an instance of ImagingAPI class with client credentials
  3. Specify input and output files
  4. Read input WMF file and upload to cloud storage
  5. Create an instance of ConvertImageRequest with input and output file formats
  6. Call convertImage method to Convert WMF to PDF using REST API
  7. Save the output PDF file on local disk

Code for WMF to PDF Conversion in Java Low Code API

String ClientID = Client.getID(); //replace Client.getID() with your own client ID here
String ClientSecret = Client.getSecret(); //replace3 Client.getSecret() with your own client secret here
String APIBaseUrl="https://api.aspose.cloud";
String Local_Path = "C:/Temp/";
ImagingApi imagingApiSdk = new ImagingApi(ClientSecret, ClientID, APIBaseUrl);
// Input & output file names
String inputFileName = "WMFtoPDF.wmf";
String outputFileName = "WMFtoPDF.pdf";
try {
// Upload local image to Cloud Storage
File inputFile = new File(Local_Path + inputFileName);
FileInputStream inputFileStream = new FileInputStream(inputFile);
byte[] inputImageData = IOUtils.toByteArray(inputFileStream);
UploadFileRequest uploadFileRequest = new UploadFileRequest(inputFileName, inputImageData, null);
FilesUploadResult filesUploadResult = imagingApiSdk.uploadFile(uploadFileRequest);
String outputFormat = "pdf";
String remoteFolder = null; // Input file is saved at the root of the storage
String remoteStorage = null; // Cloud Storage name
ConvertImageRequest convertImageRequest = new ConvertImageRequest(inputFileName, outputFormat, remoteFolder, remoteStorage);
byte[] convertedImageData = imagingApiSdk.convertImage(convertImageRequest);
// Save exported image to local storage
FileOutputStream fileOutputStream = new FileOutputStream(Local_Path + outputFileName);
fileOutputStream.write(convertedImageData);
fileOutputStream.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
