Change the export quality

FusionExport lets you export charts in three different qualities. The three qualities are differentiated as good, better or best. By default FusionExport exports chart in better quality.

Use the -q or --quality option to customize the quality of the exported charts.

To change the export qulaity, you can use the CLI or SDKs of the languages mentioned below, using the command given below:


    $ fe -c column_chart_config.json -q best


    // Exporting a chart with best quality
    const path = require('path');

    // Require FusionExport
    const {
        ExportManager,
        ExportConfig
    } = require('../');

    // Instantiate ExportManager
    const exportManager = new ExportManager();

    // Instantiate ExportConfig and add the required configurations
    const exportConfig = new ExportConfig();

    exportConfig.set('chartConfig', path.join(dirname, 'resources', 'single.json'));
    exportConfig.set('quality', 'best');

    // provide the export config
    exportManager.export(exportConfig);

    // Called when export is done
    exportManager.on('exportDone', (outputFileBag) => {
        outputFileBag.forEach((op) => {
            console.log(DONE: ${op.realName});
        });

        ExportManager.saveExportedFiles(outputFileBag);
    });

    // Called on each export state change
    exportManager.on('exportStateChange', (state) => {
        console.log([${state.reporter}] ${state.customMsg});
    });

    // Called on erroe
    exportManager.on('error', (err) => {
        console.error(err);
    });
