Failed to convert page to image

[siamraj]

My Code :
var fs = require('fs');
var PDFImage = require("pdf-image").PDFImage;

var pdfImage = new PDFImage("test.pdf");
pdfImage.convertPage(0).then(function (imagePath) {
// 0-th page (first page) of the slide.pdf is available as slide-0.png
fs.existsSync("Public/slide-0.png") // => true
}).catch((err)=>{
console.log(err)
});

Error MSG :

{ message: 'Failed to convert page to image',
error:
{ Error: Command failed: convert "test.pdf[0]" "test-0.png"
Invalid Parameter - "test-0.png"

Hey @siamraj,
You have this problem because the convert process didn't worked.
The error message might can be optimised here but primarily you have to fix the convert command.
Try this on your command line - this will fail:
convert "test.pdf[1]" "test-0.png"

You already found: #30

Try to install pdf-poppler or poppler with brew as described in readme
