Tiff doesn't support buffer

[dungvt]

Hi all,
I can see some previous issued, and i know, tiff image was suppot from buffer.
But, to day, i get error, that say: "Tiff doesn't support buffer" when try to get dimenstion of a tiff image.
I'm using newest version (0.6.1) from npm https://i.imgur.com/vSqORFQ.png

My code:
var dimensions = sizeOf(response.Body);

response.Body is buffer of tiff image, i get it from amazon s3

What is wrong in here?
Can you help me on this case?

Same here !

[c060604]

I use a dng file, it also throw out the same error.

@c060604 dng are raw files. I've created a separate issue for that #136

[geogeim]

same issue here
i think the library is designed to work with partial data in buffer mode (i.e. get the size of the picture by reading a few bytes) which is not supported because the tiff code needs the size of the file. but in my case i know that my buffer is complete so it would be nice to find a way of working with tiff files without dropping them to disk. it would probably need to change the api interface somehow and that sucks

[netroy]

@geogeim it's the other way around. Tiff isn't supported when using the async api for files. but if you already have an entire tiff file in buffer, you can pass the buffer to imageSize function, and it'll work.
Dumping the buffer to disk is not going to help, as this library doesn't want to load entire files into buffer itself.
Loading full tiff files in a buffer, and passing that buffer, is the only way tiff files are supported.

hi @netroy , I already try using imageSize instead of getImageSize, the error still happen, is there any workaround for this?

[netroy]

@wildansupernova can you please share the code with us?

@wildansupernova can you please share the code with us?

thanks for replying @netroy

here the example repo https://github.com/wildansupernova/image-size-test-tiff-error , you can try the error

import * as fs from 'fs';
import { imageSize } from "image-size";
function streamToBuffer(stream): Promise<Buffer> {
    return new Promise<Buffer>((resolve, reject) => {
      const bufferArray: Uint8Array[] = [];
      stream
        .on("data", (chunk) => {
          bufferArray.push(chunk);
        })
        .on("error", (error) => {
          reject(error);
        })
        .on("end", () => {
          const content = Buffer.concat(bufferArray);
          resolve(content);
        });
    });
  }

const runExample = async () => {
    const result = fs.createReadStream("0d63278b-ec67-41d9-b156-88e65d4edacb.tiff");
    const buffer = await streamToBuffer(result)
    const dimensions = imageSize(buffer)
    console.log(dimensions);
}

runExample()

my error

let me know your though about this

[netroy]

@wildansupernova TIFF don't support streams or buffers (yet).
please try something this instead:

import { promisify } from "util"
import { imageSize } from "image-size"
const sizeOf = promisify(imageSize)

const runExample = async () => {
  const dimensions = await sizeOf("0d63278b-ec67-41d9-b156-88e65d4edacb.tiff")
  console.log(dimensions)
}

runExample()

@netroy ok, thanks for the clarification

Any update with this? Would love to be able to support TIFF images from a buffer.
