npm install pdf-image
Ensure you have convert
, gs
, and pdfinfo
(part of poppler) commands.
sudo apt-get install imagemagick ghostscript poppler-utils
brew install imagemagick ghostscript poppler
var PDFImage = require("pdf-image").PDFImage;
var pdfImage = new PDFImage("/tmp/slide.pdf");
pdfImage.convertPage(0).then(function (imagePath) {
// 0-th page (first page) of the slide.pdf is available as slide-0.png
fs.existsSync("/tmp/slide-0.png") // => true
});
var PDFImage = require("pdf-image").PDFImage;
var pdfImage = new PDFImage("/tmp/slide.pdf");
pdfImage.convertFile().then(function (imagePaths) {
// [ /tmp/slide-0.png, /tmp/slide-1.png ]
});
var PDFImage = require("pdf-image").PDFImage;
var pdfImage = new PDFImage("/tmp/slide.pdf", {
combinedImage: true
});
pdfImage.convertFile().then(function (imagePaths) {
// /tmp/slide.png
});
Following example shows an example of pdf-image in Express, which gives
URLs for each pages of a PDF like
http://example.com:3000/tmp/slide.pdf/0.png
.
app.get(/(.*\.pdf)\/([0-9]+).png$/i, function (req, res) {
var pdfPath = req.params[0];
var pageNumber = req.params[1];
var PDFImage = require("pdf-image").PDFImage;
var pdfImage = new PDFImage(pdfPath);
pdfImage.convertPage(pageNumber).then(function (imagePath) {
res.sendFile(imagePath);
}, function (err) {
res.send(err, 500);
});
});
Following example shows an example of how to add imagemagick command-line options (you can find the complete list here -> http://www.imagemagick.org/script/convert.php):
var pdfImage = new PDFImage(pdfPath, {
convertOptions: {
"-resize": "2000x2000",
"-quality": "75"
}
});
