pdf-to-png-converter

Node.js utility to compare PNG files without binary and OS dependencies.

Getting started

Installation:

npm install -D pdf-to-png-converter

Example

test(`Convert PDF To PNG`, async () => {
    const pngPages: PngPageOutput[] = await pdfToPng(pdfFilePath, { // The function accepts PDF file path or a Buffer
        disableFontFace: false, // If disabled, fonts will be rendered using a built-in font renderer that constructs the glyphs with primitive path commands.
        useSystemFonts: false, // When `true`, fonts that aren't embedded in the PDF document will fallback to a system font.
        viewportScale: 2.0, // The desired scale of PNG viewport
        outputFilesFolder: 'output/folder', // folder to write output png files,
        pdfFilePassword: 'password', // password for encrypted PDF,
        pages: [1, 3, 11]   // Subset of pages to convert (first page = 1, optional)
    });

   ...
});

Output

{
    name: string; // PNG page name in a format `{pdfFileName}_page_{pdfPageNumber}.png`,
    content: Buffer; // PNG page content
    path: string; // path to stored PNG file (empty string if outputFilesFolder is not provided)
};
