Follow this article to Node.js REST API conversion of a BMP file into a PDF using the Aspose.PDF Cloud SDK. The ImageTemplate class lets you customize how each image appears in the resulting PDF.

Prerequisite

• Create an account and obtain API credentials to convert a BMP file to a PDF.
• Download the Aspose.PDF Cloud SDK for Node.js
• Set up a Node.js project and add the SDK as a dependency.

Steps to Convert BMP to PDF using Node.js REST Interface

1. Create an instance of the PdfApi class, providing your client ID and client secret.
2. Upload the source BMP file to Aspose Cloud storage by reading it into a memory stream from the local disk.
3. Build an ImageTemplate that defines how the BMP will be placed in the PDF.
4. Add each ImageTemplate to a List (one template per image).
5. Construct an ImageTemplatesRequest using the list of image templates.
6. Invoke the PutImageInStorageToPdf() method, passing the desired output PDF name and the request object.
7. Download the generated PDF from Cloud storage and save it locally.

These steps outline the creation of a Bitmap‑to‑PDF converter with the Node.js REST API: upload BMP files, define image templates, bundle them into an ImageTemplatesRequest, and finally call PutImageInStorageToPdf() to produce a multi‑page PDF.

Code to Change BMP to PDF using Node.js REST Interface

The sample demonstrates a BMP‑to‑PDF conversion using the low‑code Node.js API. With ImageTemplate you can set page margins, page height, and width, as well as specify the ImageSrcType (e.g., Common or EMF) to suit your needs.
