colorjs / get-image-colors Goto Github PK

This library looks awesome but for the life of me cant get it going on storybook with webpack or nextjs.

Hello! 👋🏼

This is related with colorjs/get-svg-colors#72. The is-svg dependency used by get-svg-colors has a vulnerability, I already opened a PR to fix it colorjs/get-svg-colors#73, as soon as we merge and release this we should update the dependency 😊

Would be very helpful thank you!

Hi Creators,

This app is extremely helpful and works really well. But I am having trouble finding documentation on how I can specify the number of colors I want in my palette.

Can you point me in the direction in the documentation if there is one? If there isn't can y'all write up one?

Thanks.

See: GHSA-w7q9-p3jq-fmhm

get-image-colors depends on get-pixels with range ^3.3.2, which depends on jpeg-js with range ^0.3.2, which has the vulnerability in the advisory above.

Please remove this deep dependency on the vulnerable jpeg-js package, which was patched in v0.4.0

I was trying to fetch colours of images that are more than 4 mb (aprox). The library gets stuck and does not respond. We finally have to restart the server once this happens.

More Context:

1. We're using this library on our server side to fetch colour of images uploaded.
2. It works like a charm on my local system even for images as big as 20-25mb.
3. However, When running on the live server, once an image more than 4 mb is given, the library crashes.
4. Our server is on AWS, It's an EC2 instance with 2 cores and 1 gb of ram (T4g micro).

Because this works fine on my local, does it have to do something with the heap size on the server? Is there a possible way to configure my node server to allow more memory (If that is the issue) ?

So I am trying to loop through an array of image urls to get the average picture's color. When I go to try using a buffer as a picture source, I get an invalid GIF error of some sort. I then try downloading via an axios stream and am able to view the picture after downloading, but get this Marker was not found error...

Error: marker was not found

Here is my code.

let index2 = 0
let interval2 = setInterval(() => {

                downloadImage(images.data[index2].sizes[0].url).then((name) => {
                  console.log('Writting :', objectName, ' to file')

                  getColors(__dirname + '/images/' + name + '.jpg').then(colors => {
                    console.log(colors)
                    if (colors[0]._rgb[2] >= 180) {
                      console.log('found good image!')
                      imageLinks.push(images.data[image].sizes[0].url)
                    }
                  })
                    .catch(err => {
                      console.log("Error! ", err) //This is where I catch the Marker not found error
                    })
                })
                if (++index2 == images.data.length) {
                  console.log('finished looping through images... on to the next array.')
                  clearInterval(interval2)
                }

              }, 1000)

This is my downloadImage function just in case there is something wrong with how im downloading.

const downloadImage = async (url) => {
 let name = uuidv4()
 const writer = fs.createWriteStream(path.resolve(__dirname + ‘/images/’ + name + ‘.jpg’))
 const image = await axios({
   url,
   method: ‘GET’,
   responseType: ‘stream’
 })

 image.data.pipe(writer)

 return new Promise((resolve, reject) => {
   writer.on(‘finish’, resolve(name))
   writer.on(‘error’, reject)
 })
}

example:
count: 7 => return 7colors
count: 8 => return 7 colors
count: 30 => return 29 colors

Hey guys thanks for this great repo.

I created a docker image for this project.

https://hub.docker.com/repository/docker/thebakers/get-image-colors

I makes using the project a lot easier. The only comment you need to know is:

docker run -p 3013:3000 thebakers/get-image-colors:latest

and then use it with: http://localhost:3013/api/color?url=https://res.cloudinary.com/hvioxpubt/image/upload/v1631368381/foplzsz9zemxdfqunr8m.jpg

Hi, I started with this image, it's someone's podcast art: http://static.libsyn.com/p/assets/e/3/f/f/e3ffacb40e9f9ebc/Logo_with_text.jpg

It's a simple graphic that is blue, red, yellow and white. For some reason however, it's giving me back several shades of orange, blue and white (missing yellow and red, don't know where the orange came from):

getColors(filePath).then(colors => {
        const palette = colors.map(color => color.hex());
        res.send({ palette });
      })

"palette": [
        "#fbfbfb",
        "#252c7c",
        "#c37025",
        "#c1b8a3",
        "#d58180"
    ]

I need to get dominant color for specific image (or color frequency).
For example, Color Thief can do it.
Is it possible with get-image-colors?
Thanks

as of right now, this package is adding 5 severe vulnerabilities to my project, itd be nice if the dependencies were updated :)

Hi,
I have an issue when using getColors, it log error: "Error: Invalid File Type"
I am writing the automation scripts in synchronous style with Chimp.
My scripts is as below:

var buffer = fs.readFileSync(path.join(__dirname, '/../../resources/uploadData/', '1.png'));
getColors(buffer, function(error, colors){
    if (err) throw err; // it doesn't log error
    console.log(buffer); // Log: <Buffer 89 50 4e 47 0d 0a ....>
    console.log(error); // Log "Error: Invalid File Type"
});

Please help me where I am wrong? Thanks!

How can i get color data from "req.files.image.tempFilePath" ?
