Is in your code files an array?

[pankajDevFrontend]

Is in your code files an array?

nope, it's just single file.

[w3nl]

Ok, the current code can only handle an array.

You can e.g. send an array with the single file.

new Converter({
      files: [file],

[pankajDevFrontend]

th the single file.

ok let me check with this solution.

callback: function (data) {
        console.log(data.failed, data.success, data.files, data.time);
      }

there is no response or any error getting inside the callback function.

[w3nl]

Can you provide more details?
What is the response message?
Can you provide more code?

callback: function (data) {
        console.log(data);
      }

(Can you give all information)

[pankajDevFrontend]

ovide more code?

Here is full code

var Converter = require('ppt-png');


  render() {
    return (
      <div>
        <input
          type="file"
          ref={ref => this.fileFront = ref}
          accept=".png,.jpg,.jpeg,.ppt"
          name="frontdoc"
          onChange={this.handleConvertingfunction} />
      </div>
    );
  }
}

  handleConvertingfunction = (event) => {
    let files = event.target.files[0];
    let mfiles = [];
    mfiles.push(files);
    new Converter({
      files: [mfiles],
      output: 'output/',
      invert: true,
      callback: function (data) {
        console.log(data.failed, data.success, data.files, data.time);
      }
    }).run();
  }

but not getting any kind of log or detail or error.

What framework are you using?

I have only test it just in pure Node.js, where files is an array of local files. (not uploaded to a temp dir)
So if you show the mfiles, (with e.g. console.log), it can be a path or object with originalname and path.
https://github.com/w3nl/ppt-png/blob/master/js/convert.js#L193

If you would see more details in the log, you can also change the logLevel to 4.

Ok, the LibreOffice convert doesnt work.
You can test this just with the LibreOffice command:
libreoffice --headless --convert-to pdf --outdir output/ '/Volumes/Projects/REACTJS/my-app/src/assets/sample.ppt'

Is LibreOffice installed?
And is your LibreOffice up-to-date?

You can also use another software to convert the document, see: Issue #2

yes libreOffice installed, need to create output directory like that ?

[w3nl]

In your code the output folder is output/.
That is a relative path in your project.
And yes, you have to create the folder output in your project.

But LibreOffice say: commandnotfoundatChildProcess ...

So it looks like LibreOffice is failing over the command.

Have you tried the LibreOffice command in your terminal?

can you share me or explain me command about terminal please ?

[pankajDevFrontend]

i have changed command libreoffice to other but this time i am getting new this error

[w3nl]

LibreOffice (or another alternative) should convert the spreadsheet (ppt/pptx/ods/...) to a pdf file.
This pdf file should be stored in the output folder.

The pdf has for every slide a page.
Than the pdf will be convert to images, every page will converted to an image.
The package https://www.npmjs.com/package/pdf2image is used for this process.
This package use Imagemagick for the convert progress.
https://bitbucket.org/RicardoCacheira/pdf2image/src/e06968cef3dfa776e039a1b49931389831b71945/index.js#lines-297

I'll have to figure out why the pdf2image action doesnt work.

[w3nl]

I have made some changes, can you test it again with version 0.5.1?

ok let me check

[pankajDevFrontend]

Getting same error, please check attached screenshot.

[w3nl]

Has the output for write rights?

[PieterWigboldus]

With version 0.5.2 you receive more information about reading the pdf file.
So if it is a write problem, you'll see it.

[PieterWigboldus]

Let me know if it works.

[pankajDevFrontend]

Let me know if it works.

yes, i have checked and still same issue.

[pankajDevFrontend]

Has the output for write rights?

Yes

[PieterWigboldus]

Do you have some information about:
Operation system
Node version
ImageMagick version
pdfinfo version

[PieterWigboldus]

@pankajDevFrontend Let me know if i can help you.
If you send more details about your system, i can simulate the same situation.

[pankajDevFrontend]

Operation system . - Mac Mojave 10.14.1 (18B75)
Node version . - v11.12.0
ImageMagick version - Version: ImageMagick 7.0.8-59 Q16 x86_64 2019-08-05 https://imagemagick.or
pdfinfo version - Not able to get pdfinfo version

[PieterWigboldus]

If pdfinfo -v in your terminal doesnt work, you need to install the pdfinfo package.
I dont have test the package in node 11, but i think i also works in node 11.
You can try node 10 or 12, that are active node versions (https://github.com/nodejs/Release)
I recommend nvm to switch between node versions: https://github.com/nvm-sh/nvm

[w3nl]

Can i close this issue @pankajDevFrontend ?
