PDF Creation

The Docutain SDK for Capacitor comes with the ability to create searchable PDF documents either from a scanned document with Docutain's Scanner SDK or imported file.

Initialization​

Initialize the Docutain Capacitor SDK as described here.

Create a PDF​

import { DocutainSDK, PDFPageFormat } from '@docutain/capacitor-plugin-docutain-sdk'

//...
//scan or import file
//...

try{    
    var destinationUri = (await Filesystem.getUri({ path: "sample.pdf", directory:Directory.Data })).uri;
    const pdfUri = (await DocutainSDK.writePDF({
        fileUri: destinationUri,
        overWrite: true,
    })).fileUri 
} catch (error) {
    console.error(error);
}
tip

You can specify to overwrite an existing file and the PDF page format by providing the appropriate value.

PDF Page Format​

You can specify the PDF page format by providing the appropriate value:

    const pdfUri = (await DocutainSDK.writePDF({
        fileUri: destinationUri,
        pageFormat: PDFPageFormat.A4
    })).fileUri

PDF Compression​

You can specify a maximum file size for the PDF. If the uncompressed PDF would exceed the maximum file size you have set, it will get compressed until the maximum file size is reached. Please be aware, that if the PDF gets compressed, the quality decreases and the PDF generation will take longer. In order to set a maximum file size, set the maxSizeKB parameter to your desired size. It needs to be set in KB, so if you want 10MB for example, set it to 10 * 1024. Please check below example:

    const pdfUri = (await DocutainSDK.writePDF({
        fileUri: destinationUri,
        maxSizeKB: 10240
    })).fileUri
