TIFF image decoder written entirely in JavaScript.
$ npm install tiff
This package is written using ES2015 features. It is natively compatible with recent versions of Google Chrome and Node.js. You can transpile it with a tool like babel if you need to support more JavaScript engines.
The library can currently decode greyscale and RGB images (8, 16 or 32 bits). It does not support any compression algorithm yet.
The package is in early development and API should be considered unstable.
I am currently only focused on extending TIFF format support and will work on the API afterwards.
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.
size - number of pixelswidth - number of columnsheight - number of rowsbitsPerSample - bit depthxResolutionyResolutionresolutionUnitReturns 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.
