  3. Call the PspdfkitProcessor.generatePdf() method with the following parameters:

Generate PDFs from images

The following code demonstrates how to create a PDF from an image:

// Image file from which to generate the PDF.
File img = File('<readable-image-path>');


// File path where the generated PDF will be saved.
String outputPath = '<writable-output-file-path>';


// A list of PDF pages from the image URI.
List<NewPage> pages = [
    NewPage.fromImage(
        PdfImagePage.fromUri(img.uri, PagePosition.center)),
    NewPage.fromImage(
        PdfImagePage.fromUri(img.uri, PagePosition.center)),
];
// Generate a PDF from an image and save it at `[outputPath]`.
var filePath = await PspdfkitProcessor.instance.generatePdf(
    pages, outputPath); // Or `generatePDFFromImage`.
