Resize images

Hello, I have been using manet, so far is works pretty good, I would like to know if it would be hard to implement image resizing, for example I would like to get thumbnails for desktop screenshots, I would like to implement this myself however I don't know exactly where should I place the code.

https://www.npmjs.com/package/resize

this seems like a good library for this.

function minimizeImage(src, dest, cb) {
    squirrel(
        IMIN_MODULES, IMIN_OPTIONS,
        (err, Imagemin) => {
            const safeCb = (err) => {
                if (err) {
                    logger.error(err);
                }
                cb();
            };

            if (err) {
                safeCb(err);
            } else {
                const imin = new Imagemin()
                    .src(src)
                    .dest(dest)
                    .use(Imagemin.jpegtran({progressive: true}))
                    .use(Imagemin.optipng({optimizationLevel: 3}))
                    .use(Imagemin.gifsicle({interlaced: true}))
                    .use(Imagemin.svgo());

                imin.run(safeCb);
            }
        }
    );
}

I am guessing I should make a function like this one ?

and then add it here

function runCapturingProcess(options, config, outputFile, base64, onFinish) {
    const scriptFile = utils.filePath(SCRIPT_FILE),
          command = cliCommand(config).split(/[ ]+/),
          cmd = _.union(command, [scriptFile, base64, outputFile]),
          opts = {
              timeout: config.timeout
          };

    logger.debug(
        'Options for script: %s, base64: %s, command: %s',
        JSON.stringify(options), base64, JSON.stringify(cmd)
    );

    utils.execProcess(cmd, opts, (error) => {
        if (config.compress) {
            minimizeImage(outputFile, config.storage, () => onFinish(error));
            //resize here ?
        } else {
            onFinish(error);
        }
    });
}

We could use this as well. @vbauer do you think @xkidro is on the right track here?

@xkidro @GuiSim Yes, I think it should be something here (btw, I'm opened for PR)

Any update on this?

Has anyone implemented resize screenshot functionality?

I am trying to install resize npm package into Manet but I am getting following error.

`> [email protected] install /usr/local/lib/node_modules/manet/node_modules/graphicsmagick2

Any thought on this?

It was a permission related issue.. Fixed it.
