TIFF image decoder written entirely in JavaScript.
Maintained by Zakodium
npm i tiff
The library can currently decode greyscale and RGB images (8, 16 or 32 bits). It supports LZW compression and images with an additional alpha channel.
Images compressed with Zlib/deflate algorithm are also supported.
Decodes the file and returns TIFF IFDs.
Each decoded image is stored in an IFD
.
The data
property is a Typed Array containing the pixel data. It is a Uint8Array
for 8bit images, a Uint16Array
for 16bit images and a Float32Array
for 32bit images.

Returns the number of IFDs (pages) in the file.
Returns true if the file has 2 or more IFDs (pages) and false if it has 1. This is slightly more efficient than calling pageCount()
if all you need to know is whether the file has multiple pages or not.
