var Tiff = require('tiff.js');

var fs = require('fs');



var filename = process.argv[2];

var input = fs.readFileSync(filename);

var image = new Tiff({ buffer: input });

console.log(filename + ': width = ' + image.width() + ', height = ' + image.height());

API

see tiff.d.ts

Note

- ~~This library does not support JPEG-based compressed TIFF files~~
- Fixed by Tetedeiench
- When you load large tiff file, you will see the error message "Cannot enlarge memory arrays in asm.js"
- in such case, please call 'Tiff.initialize({TOTAL_MEMORY: ... })' before you create a Tiff instance
- This JavaScript library uses only some parts of the LibTIFF features
- To be more precise, I use following functions only
- TIFFOpen, TIFFClose, TIFFGetField, TIFFReadRGBAImage, TIFFSetDirectory, TIFFCurrentDirectory, TIFFReadDirectory

Alternatives

- photopea/UTIF.js
- image-js/tiff
