Which 10 image processing libraries in the practical open source Javascript library are recommended? in order to solve this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Introduction

For many people, using Javascript to process images is not a very simple task, but fortunately we can use third-party libraries to achieve the functions we want.

1. Pica

This plug-in saves upload time by reducing the upload size of large images. It can resize the image in the browser without pixelation and is quite fast. It will automatically select excellent available technologies from web-workers, web assembly, and createImageBitmap and pure JS.

2. Lena.js

This is an image processing library with 22 filters.

3. Compressor.js

This is a simple JS image compressor that uses the browser's native canvas.toBlob API to handle image compression. You can set the compressed output quality to 0 to 1.

4. Fabric.js

Fabric.js allows you to use JavaScript to easily create simple shapes, such as rectangles, circles, triangles, and other polygons, on HTML elements on a web page, or more complex shapes made up of many paths. Fabric.js will then allow you to use the mouse to manipulate the size, position, and rotation of these objects. You can also use the Fabric.js library to change some properties of these objects, such as color, transparency, depth location on the web page, or select groups of these objects. Fabric.js also allows you to convert SVG images into JavaScript data, which can be used to put it into elements.

5. Blurify

Used to blur images and has elegant downgrade support from css mode to canvas mode. The plug-in works in three modes:

Css: using the filter attribute

Canvas: exporting base64 using canvas

Auto: css mode is preferred, otherwise automatically switch to canvas mode

A simple and effective blurred image can be obtained simply by passing the image, blur value and pattern to the function.

6. Merge Images

This library makes it easy to combine images together. Sometimes, using a canvas can be cumbersome, especially if you only need a canvas context to do relatively simple things (such as merging some images together). Merge-images abstracts all repetitive tasks into a simple function call. Images can overlap and reposition each other. This function returns a Promise that parses to base64 data URI. Both browser and Node.js are supported.

7. Cropper.js

The plug-in is a simple JavaScript image clipper that can crop, rotate, scale and scale images in a visual environment. It also allows you to set the aspect ratio.

8. CamanJS

It is the canvas operation library of Javascript. It combines an easy-to-use interface with advanced, efficient image / canvas editing technology. It is easy to extend with new filters and plug-ins, and it has a wide range of image editing capabilities, which are growing. It is completely independent of the library and can be used in NodeJS and browsers. You can select a set of preset filters or manually change attributes (such as brightness, contrast, saturation) to get the desired output.

9. MarvinJ

MarvinJ is a pure JavaScript image processing framework derived from Marvin Framework. MarvinJ is both simple and powerful for many different image processing applications. Marvin provides a number of algorithms to manipulate color and appearance. Marvin also has automatic detection function. The ability to use basic image functions such as edges, corners and shapes is the foundation of image processing. The plug-in helps to detect and analyze the corners of objects to determine the location of the main objects in the scene. Because of this, objects can be clipped automatically.

10. Grade

The JS library produces complementary gradients generated from the first two main colors in the provided image. This allows the site to populate the div with matching gradients derived from the image. This is an easy-to-use plug-in that helps keep the appearance of the site beautiful.

Window.addEventListener ('load', function () {Grade (document.querySelectorAll (' .gradient-wrap'))})
