lovell/sharp

High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. Uses the libvips library.

sharp

The typical use case for this high speed Node-API module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.

It can be used with all JavaScript runtimes that provide support for Node-API v9, including Node.js (^18.17.0 or >= 20.3.0), Deno and Bun.

Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips.

Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed.

As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available.

Most modern macOS, Windows and Linux systems do not require any additional install or runtime dependencies.

sharp's Issues

Add option not to enlarge images

Possible options:

sharp('file.jpg', {enlarge: false}).resize(100, 100)

sharp('file.jpg').resize(100, 100).enlarge(false)

sharp('file.jpg').resize(100, 100).noEnlarge()

Say I want to resize 1000s of images to fit 100x100 but some of those are already 50x50. Than it would be nice not to enlarge those tiny images (quality degradation) and return the same input image in a callback.

streams

Does the whole buffer have to load into run time memory or is it possible with the underlying C library to implementing a true streaming api, so that a file can be streamed from disk, through sharp stream to network socket or file read stream or whatever else.

ref: http://nodejs.org/api/stream.html

Neither graphicks magik, nor image magik wrappers are capable of streams - theres one module (gm I think) that has a stream api, but its faked somewhat, the module still has to load the full image into memory regardless. So a true streaming interface for sharp would be a massive usp

Installation fails on Ubuntu trusty

I tried to follow the Installation instructions, however I'm not getting much luck and I'm unsure if I'm the one doing something wrong.

You can see how I'm setting up the Ubuntu environment by checking this gist, I'm using vagrant to create an Ubuntu machine so I've included the Vagrantfile just in case you want to replicate it.

You can find the npm_debug.log on the same gist.

If you need any extra info please ask, and i'm sorry for not providing much information, but i'm a little newbie with image manipulation libraries, so I'm not sure where to start to provide more info.

Performance boost: use shrink-on-load and enable sequential mode

https://github.com/jcupitt/libvips/issues/95#issuecomment-32346240

"You could probably speed it up a bit: you're not using the jpeg shrink-on-load feature, which can give a really huge speed boost, up to about 10x, and you're not using sequential mode, which can give an extra 30% or so, even with PNG."

https://github.com/jcupitt/libvips/blob/master/tools/vipsthumbnail.c#L294 provides an example of this.

Feature request: support bicubic interpolation (was: anti-alias?)

Trying it on some resize operations against imagemagick, the output speed is faster, but the edges of circular shapes seem to need some anti-aliasing. Is it possible with Sharp?

strings are not errors

https://github.com/lovell/sharp/blob/master/index.js#L133
https://github.com/lovell/sharp/blob/master/index.js#L144

use new Error(). this is bad form.

also, callback could be undefined, so you'd want to somehow promisify that

Memory leak

I ran a batch using sharp on ~1000 files and it ended using >300MB ram.

I created a little gist to "demonstrate" it, it download a large image and creates 800 thumbs at different sizes.
On my mbp, when finished, it takes 120MB ram (more if i increase the number of generated thumbs).

Feature request: support EXIF mirroring (was: Auto-orientation only works in some cases)

Hi Lovell,

I recently found I needed auto-orientation and was pleasantly surprised to see it now implemented in Sharp.

I ran into the following blog where the author uses a sample set of images (with various exif parameters) and show the state of "Exif orientation" on the internet.
http://www.daveperrett.com/articles/2012/07/28/exif-orientation-handling-is-a-ghetto/

His sample set is available on github:
https://github.com/recurser/exif-orientation-examples

I ran through this sample set using sharp with the autorotate() fag turned on. Only about half the images auto-rotated properly. I'm not sure if this is a bug or if I am simply doing something wrong. Feel free to let me know your thoughts and if your able to replicate this on your end.

Thanks,

• Kevin

does this lib do autoorientation and exif extraction?

if i'm going to migrate from imagemagick, i'd need this =O

I had a similar issue with the node-vips library, which I've ended up fixing like this:

↪  cat node_modules/vips/binding.gyp

        'target_name': 'vips',
        'sources': [

            'src/transform.cc'
        ],

        ],
        'cflags': [ '-fexceptions' ],
        'cflags_cc': [ '-fexceptions' ]

}

I'm very curious how could it compile without tweaks on others' systems.
brew install homebrew/science/vips alone is clearly not enough.

Error in `node': corrupted double-linked list

I'm running a batch of node services that are cropping images on demand with sharp. Every once in a while one of them will get this error which requires a hard restart (I'm running the services with forever but the error doesn't seem to be raised at the correct "level" for forever to handle it). I haven't been able to track it down to sharp specifically, perhaps it has something more to do with libvips, but I'm starting at the top of the chain.

Stack trace here:
https://gist.github.com/spro/8839678

Feature request: support image rotation

If libvips supports rotation it would be great to be able to rotate images with Sharp so that images can be transformed efficiently without having to encode/decode multiple times. Basic 90/180/270 degree rotation would be sufficient (and maybe mirroring) to accomodate EXIF orientations.

Installing libvips on Heroku

Any idea if this is possible?

Jpeg Image Quality

Hi Lovell - I really love this package. Unlike opencv which crashes from memory constraints this package is very low in memory usage and blazing fast.

One thing I would like to be able to do is change the quality of my images. I couldn't find documentation or any inline code constant on the current jpeg quality setting nor could I find a way to set it. In many of the other packages I've used you can pass in a value between 0 and 100.

Thanks,

Kevin

.resize() with .max() still crops the image

Sorry to bother you again, dunno - maybe its something on my side. Given an image - for example this one

I would like to resize it to max 100x100 which means the resulting image should fit within those bounds while maintaing the aspect ratio (no cropping). Here's my call:

sharp(file).resize(100, 100).max().toBuffer(function(err, buffer) {
});

And the image I get is this one (resized and cropped to 57x100):

Shouldn't sharp simply resize input image to 57x100 without any cropping?

Thanks.

Use Native Abstractions

There are compiler warnings with node v0.11 unstable.

../src/sharp.cc: In function ‘v8::Handle<v8::Value> Resize(const v8::Arguments&)’:
../src/sharp.cc:159:77: warning: ‘static v8::Persistent<S> v8::Persistent<T>::New(v8::Handle<T>) [with T = v8::Function]’ is deprecated (declared at /home/travis/.node-gyp/0.11.3/deps/v8/include/v8.h:5514) [-Wdeprecated-declarations]

Using https://github.com/rvagg/nan should hopefully reduce the impact of V8 changes, e.g. https://github.com/rvagg/node-postgres/commit/6cb167112ef65845dec818e7a888218fbe408483

Buffer issue

I'm using Knox to download an image on S3 and I'm stocking data in a buffer and place it in sharp constructor method.

res.setEncoding('binary');
var output = new Buffer('', 'binary');
res.on('data', function(chunck){
  output.write(chunck);
});
res.on('end', function(){
  callback(output, false);
});
// ...
sharp(rawImg)
  .resize(target.size, target.size)
  .toBuffer(function(err, image){
    if(err){
      console.log(err);
    }
    callback(image);
  });

But I have an error in the callback : Unsupported input file undefined
The buffer is not corrupted : if I output it with buffer.toString() as an express response, the image is displayed.

Do you have any idea guys ?

Allow post-resize crop

As requested by @mcgoooo in #8 (comment):

im really interested in this library, but for one killer feature. the basic needs are the rescrop function found in here.

https://github.com/hacksparrow/node-easyimage

i could try to help, but i can't write c, yet! :D"

JPEG to PNG image corruption

Maybe I hit an edge case or maybe I'm just doing something wrong, probably the latter.

This sample of code always results in a corrupted image.
However, not calling one of the sequentialRead or progressive methods fixes the problem.

var sharp = require('sharp');

sharp('firefox.jpg')
    .sequentialRead()
    .progressive()
    .toFile('firefox.png');

example:

If I use a similar firefox image but with a geometry of 2048x2048, the above script throws the "scanlines" warning, but the end result is the same.

vips warning: VipsJpeg: read gave 12288 warnings
vips warning: VipsJpeg: Application transferred too many scanlines

I tried to use the identify from ImageMagick and pngcheck to detect corrupted images but, as far as those tools can tell, the resulting image is a valid png image.

I'm currently using:

• node v0.10.29
• sharp 0.5.1
• vips-7.38.5-Tue May 20 19:11:27 WEST 2014
• OSX 10.9.3 on a Mac Mini mid 2011, with 2,3Ghz i5 and 8GB 1333 Mhz DDR3

If you need more information, please just ask.
Thanks

Feature request: inspect/identify image size/format/rotation (was: only shrink to size, don't enlarge)

not sure if vips has this option. the magicks have the > option so images are only ever shrunk and never enlarged.

if vips doesn't have the option, it's up to you guys if you want to support it in this lib, though if it were me, i wouldn't (from experiencing with the gm module, there's too much of this type of shit haha)

why jpeg buffer-buffer is slow ?

Do you know why jpeg buffer-buffer is 4-5 times slower than file-buffer ?

Library not found for jpeg

Hi there!
I'm running OS X Mavericks, and I've installed libvips via homebrew.

When I npm install sharp I get the following error:

> [email protected] install /Users/murphy/TheLab/Slimmer/node_modules/sharp

But I don't know where to start debugging. Any ideas?

Support Buffer-based I/O (in addition to the filesystem)

This sample of C++ code from John might help - https://github.com/jcupitt/libvips/issues/25#issuecomment-26486484

Support PNG format (becoming less opinionated in the process)

Support for Windows

I'd like to be able to use sharp on the Windows platform. Because libvips is available for Windows, I assume that lack of support is mostly in figuring out the build script.

Has this been investigated already? If so, what approaches have already been tried and roadblocks encountered? Knowing what's been tried so far, if anything, will help me or other potential developers come to a working solution quicker.

allow grabbing a specific frame of a gif

ex. sharp('image.gif[-1]').resize()

right now it takes the raw frame, which isn't really correct in the case of cinemagraphs

only use bluebird if native promises are not available

i.e. node 0.11.13+

abort trap error

to be fair, i think this is a node error, like many things:

> sharp('/Users/jong/Downloads/We0opiV.jpg').resize(50).toFile('test.jpg', function (){})

Enable overwriting input file

sharp('file.jpg').resize(100, 100).write('file.jpg', function(err) {
    console.log(err)l;
});

Gives:

VipsJpeg: Empty input file
vips__region_start: start function failed for image temp-1
VipsRegion: valid clipped to nothing
VipsRegion: valid clipped to nothing
VipsRegion: valid clipped to nothing

Any chance to implement file overwriting?

colorspaces and gamma correction

would be nice to support colorspaces, primarily srgb and grayscale.

consequently, i need this for gamma correction when resizing: http://www.imagemagick.org/Usage/resize/#resize_colorspace

would be nice if gamma correction was supported out of the box ^_^

after installing libvips with brew : fatal error: 'vips/vips.h' file not found

Hi couldn't install sharp on OSX 10.9.3. After installing libvips with brew, following the instructions, I get :

> [email protected] install /Users/leyla_nasib/Desktop/abr/backend/node_modules/sharp
> node-gyp rebuild

  CXX(target) Release/obj.target/sharp/src/sharp.o
../src/sharp.cc:6:10: fatal error: 'vips/vips.h' file not found

         ^
1 error generated.

So apparently it doesn't find the library ... but I have no idea how to fix that?

Survey: what are you using 'sharp' for?

I'm truly humbled by the recent surge in support for sharp.

Whilst ⭐ and the trending status they bring are both amazing, thank you, the real measure of open source success is happy users.

I'd love to find out more about how you or your organisation are using (or plan to use) this module.

Feel free to add a comment with details of who you are, what you're doing with it and why you chose it. Alternatively let me know via @lovell on Twitter.

Thank you!

DRY and flexible

Hi!
Thank you @lovell for this great lib.
Today I view some lines of code and I think we can remove some methods:
https://github.com/lovell/sharp/blob/master/index.js#L198:L208

We can add new method such as format for specify output image format.

no crop nor embed

add an option to enable a resizing without cropping nor embedding final image.

It's easy to implement, just need to inverse min/max here https://github.com/lovell/sharp/blob/master/src/sharp.cc#L138

But i'm wondering how you'd like to pass the option.

Improve documentation about libwebp installation on Ubuntu 12

The versions of libwebp in Ubuntu 12.10 and earlier are missing libwebp.pc.

Fixed in libwebp 0.2.1-3.

Homebrew pkg-config custom path

Hi, I'm trying to install this module, but getting an error, because Homebrew is setup in a custom folder (I'm using Boxen). Here is my setup:

$ brew --env
HOMEBREW_CC: clang
HOMEBREW_CXX: clang++
MAKEFLAGS: -j4
CMAKE_PREFIX_PATH: /opt/boxen/homebrew
CMAKE_INCLUDE_PATH: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/libxml2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/apache2:/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/OpenGL.framework/Versions/Current/Headers

Would it be possible to source brew --env in the binding.gyp file on Mac OS X and use the PKG_CONFIG_LIBDIR?

Ensure vips_thread_shutdown() and vips_shutdown() are called

Call vips_thread_shutdown() when ResizeAsync has done its thing.

Call vips_shutdown() via the AtExit function - see example at https://github.com/joyent/node/blob/master/test/addons/at-exit/binding.cc

This should prevent "vips__buffer_shutdown() not called for thread 0x..." warnings, as suggested by John in https://github.com/jcupitt/libvips/issues/95

Fallback on libmagick

For other input formats that jpg, tiff or png, it could fallback on libmagick loader (doesnt support buffer loading).

Gravity based resize/crop

Can you do resize/crop with specified gravity center with Sharp ?

For example if you have a rectangle image, can you crop a square from the most upper part of the image, not from the center.

Investigate reducing the dependencies to install vips

One of the hardest parts about using Sharp is setting it up. Being able to just say "npm install sharp" would make it easier for a lot of people to try it out.

Currently libvips isn't very easy to set up on an Amazon Linux box, and on Mac OS X it requires brew (there are some instances in which one may wish not to install brew). So if there were an easier way to build vips and it were integrated with Sharp's installation that could help a lot.

Speed up functional test coverage

Currently the benchmark tests/perf.js provides some of the functional test coverage for this module. These tests are intentionally slow, so this task is about moving the functional coverage these benchmark tests provide to the faster "unit" test suite.

This might also be the right time to move to mocha (or similar).

See #52 for background.

Provide a more expressive API

Beg, borrow and steal a small but perfectly formed subset of the methods provided by the gm wrapper around GraphicsMagick.

This will make it a bit easier for people to switch to using the multicore-aware libvips library should it provide the features they need.

Resize error with tiff

I get some issues trying to resize a tiff.
I wrote a little test that fails.

  function(done) {
    sharp(inputTiff).resize(240, 320).write(outputJpg, function(err) {
      if (err) throw err;
      imagemagick.identify(outputJpg, function(err, features) {
        if (err) throw err;
        assert.strictEqual(240, features.width);
        assert.strictEqual(320, features.height);
        done();
      });
    });
  }

Fall-back to libmagick or libgraphicsmagick for GIFs

Is it possible to add support for GIFs (including animated GIFs) with a simple fall-back to libmagick or libgraphicsmagick? As mentioned in here libvips/ruby-vips#38 libvips does not support GIFs directly.

Add support for WebP and TIFF image formats

"I was frustrated with the lack of support for image formats different from JPEG and PNG, since VIPS supports plenty of them (like webp, tiff, etc.)." @viktorstaikov https://github.com/jcupitt/libvips/issues/103#issuecomment-35390774

return promises if no callback provided

so i can use it with generators, please :D

tiff -> webp segfaults

tiff image: http://samples.fileformat.info/format/tiff/sample/3794038f08df403bb446a97f897c578d/CCITT_1.TIF?AWSAccessKeyId=0V91BEFA7GM093MEVMG2&Signature=QuMuJSdkorfmggoDhI0KKTfJmr4%3D&Expires=1402039078
