So, I use some lib to join countable images in specific way to one single image.
This lib use Jimp library to done it and after all joins return a Jimp
object. Like this:
Jimp {
_background: 0,
bitmap: {
data: <Buffer 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ... 2359246 more bytes>,
width: 768,
height: 768
}
}
After this joining I need convert this Jimp
object to node Buffer
object without writing image as file to disc and return Buffer
to use it in next steps.
Is it possible? I cant find anything in Jimp DOCs. And when I try write Jimp.bitmap.data
to file, this image is corrupted...
Thanks!
So, I found solution. There is a method in Jimp lib for this. But no one row from DOCs not describe this. Working solution:
const Jimp = require('jimp');
const img = Jimp.read('img.png');
img.getBuffer(Jimp.MIME_PNG, (err, buffer) => {
console.log(buffer);
});
And console output:
<Buffer 89 50 4e 47 0d 0a 1a 0a 00 00 00 0d 49 48 44 52 00 00 03 00 ... 211452 more bytes>
That's works pretty good for me.
