Another advantage is that you don't need to load every image individually, which can improve load performance. First, we’re using querySelectorAll to get the slides from our container. For instance, if you want to make a chart you could have a PNG image containing all the necessary text in a single file and depending on your data could change the scale of your chart fairly easily. When this script gets executed, the image starts loading. To do this, you can use the convenient Image () constructor: const img new Image() // Create new img element img.src myImage.png // Set source path. const images document.querySelectorAll('img') Then, we will call the setInterval () method which takes two arguments: A Callback function. Another option is to create new HTMLImageElement objects in our script. ![]() To do this, you can use the convenient Image () constructor: const img new Image() // Create new img element img.src 'myImage.png' // Set source path. First, let’s get all the image DOM elements and assign them to an images variable, which will be an array. Another option is to create new HTMLImageElement objects in our script. You could have all elements in a single image file and use this method to composite a complete drawing. For simplicity sake, I’m going to stick with the setInterval () method. Slicing can be a useful tool when you want to make compositions. Does not support uploading images from the device. Also supports pasting files and substitutions ofThe last four parameters define the rectangle into which to draw the image on the destination canvas. Final result of guide series learning how to create own Block Tool for Editor.js Simple Image paste image URL and get the image Block rendered. The first four parameters define the location and size of the slice on the source image. ![]() To really understand what this does, it may help to look at this image: Given an image, this function takes the area of the source image specified by the rectangle whose top-left corner is ( sx, sy) and whose width and height are sWidth and sHeight and draws it into the canvas, placing it on the canvas at ( dx, dy) and scaling it to the size specified by dWidth and dHeight. drawImage(image, sx, sy, sWidth, sHeight, dx, dy, dWidth, dHeight) It lets us cut out a section of the source image, then scale and draw it on our canvas. The third and last variant of the drawImage() method has eight parameters in addition to the image source.
