kandi X-RAY | UTIF.js Summary

UTIF.js is a JavaScript library typically used in Artificial Intelligence, Computer Vision applications. UTIF.js has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i sw-utif' or download it from GitHub, npm.

A small, fast and advanced TIFF / EXIF (+ DNG, CR2, NEF and other TIFF-ish files) decoder and encoder. It is the main TIFF library for Photopea image editor. Try to open your TIFF file with Photopea to see, if UTIF.js can parse it. For RAW files, UTIF.js only decodes raw sensor data (and JPG previews, if there are any). It does not convert the raw data into a displayable image (RGBA). Such conversion is complex and out of scope of this library.

            Unable to render TIFF images and add it as a Fabric Object
            Asked 2019-Oct-11 at 01:30

            I've read the tutorials: http://fabricjs.com/articles and the docs about Fabric Objects.

            I was able to load JPG and PNG images, but in my project I need to load TIFF images onto the canvas and be able to apply filters on it. I'm able to render TIFF images using the canvas context, but whenever 'renderAll()' is called it clears the context and my TIFF image is cleared. Also I cannot perform other operations like zoom, pan, brightness and contrast since I can't render it.

            Can someone please help me understand how I can convert a TIFF image into a Fabric Object so that I can do all standard fabric.Object related operations on it.

            Here are the steps I followed:

            1. To load a mock TIFF image I'm reading it as an arraybuffer.

            I didn't find any mention of something able to handle ImageBitmap in fabric's github repo.

            However, you can very well create a Fabric.Image from an HTMLCanvasElement. So you would have to draw this ImageBitmap on a canvas, and if we're going to use a canvas anyway, better to do it at the previous step, when you get an ImageData:

            I am trying to display .tiff files in the browser and am using a JavaScript plugin called UTIF.js.

            Note: I know it's a bad idea to display tifs in the browser, but for my particular use case I need to do so.

            In data you created a variable called images. But you are calling this.image in mounted which is not defined.

            Vulnerabilities

            No vulnerabilities reported

            Install UTIF.js

            Download and include the UTIF.js file in your code. If you're in NodeJS or otherwise using NPM, run:. TIFF files may have various number of channels and various color depth. The interpretation of data depends on many tags (see the TIFF 6 specification). The following function converts any TIFF image into a 8-bit RGBA image.
            buffer: ArrayBuffer containing TIFF or EXIF data
            returns an array of "IFDs" (image file directories). Each IFD is an object, keys are "tXYZ" (XYZ is a TIFF tag number), values are values of these tags. You can get the the dimension (and other properties, "metadata") of the image without decompressing pixel data.
            buffer: ArrayBuffer containing TIFF or EXIF data
            ifd: the element of the output of UTIF.decode()
            If there is an image inside the IFD, it is decoded and three new properties are added to the IFD:
            width: the width of the image
            height: the height of the image
            data: decompressed pixel data of the image
            ifd: image file directory (element of "ifds" returned by UTIF.decode(), processed by UTIF.decodeImage())
            returns Uint8Array of the image in RGBA format, 8 bits per channel (ready to use in context2d.putImageData() etc.)
