            trying to get random gifs at onClick from GIFs API
            Asked 2021-Jan-22 at 23:52

            I am trying to display random gifs at onClick from GIFs API, but I am getting an error:

            'Cannot read property 'images' of undefined'

            when trying to get the URL for images.

            Additionally, I have created a handleClick function to get random GIFs on every click.

            ANSWER

            Answered 2021-Jan-22 at 23:52

            When the data is loading, data (and thus results) is an empty array. In your GifList, when data is empty randomNumber always equals 0. Then, when you map the randomGifs array, you try to access results[0], which is undefined since results is empty. This causes the error, since undefined is not an object with property images.

            You should add a check for whether results is empty (or whether results[random] is undefined) to solve the issue.

            Z-index blocks the functioning of the gif animation | Jquery CSS HTML JS
            Asked 2020-Dec-13 at 16:57

            I tried to create an on-hover gif animation in an image block using jquery.js.

            I use these animations in horizontal or vertical blocks arranged in a grid of three columns. When you hover over the block, the gif is launched, a colored form in blend mode is added with a typography over this gif

            In my first example everything works fine, but when I wanted to add this code to a page of my website and changed the Z-index so that these elements no longer overlap on top of my menu-wrapper , the gif did not work anymore (second example).

            Why is there so much padding in GIF Encoding/Decoding between blocks
            Asked 2019-Apr-12 at 18:26

            I've been working on a custom GIF decoder for a project that I'm working on that requires as little of the GIF data to be stored in RAM as possible (so effectively I pull everything out of the file as I need it, byte by byte).

            I've been working from the following tutorial:

            http://matthewflickinger.com/lab/whatsinagif/bits_and_bytes.asp

            with a little help from the specification itself:

            https://www.w3.org/Graphics/GIF/spec-gif89a.txt

            I can do both the non-animating GIF and the traffic light animated example with my decoder. But when I try to go through a GIF exported from www.piskelapp.com (which uses gif.js as its exporter), I get a lot of padding between different blocks, padding where in some cases there shouldn't be according to the specification.

            For example, the following animation https://www.piskelapp.com/p/agxzfnBpc2tlbC1hcHByEwsSBlBpc2tlbBiAgICA_eOjCgw/edit has a beginning that looks like this:

            ANSWER

            Answered 2019-Apr-12 at 18:26

            The answer is fairly straightforward. The GIF exporter used by Piskel simply has a poor implementation.

            It explicitly states in the GIF89a spec:

            "The Graphics Interchange Format(sm) as specified here should be considered complete; any deviation from it should be considered invalid, including but not limited to, the use of reserved or undefined fields within control or data blocks, the inclusion of extraneous data within or between blocks, the use of methods or algorithms not specifically listed as part of the format, etc."

            The piece I want to point out is "the inclusion of extraneous data within or between blocks". In this case, the issue is data within blocks, for some reason the exporter Piskel uses always fills the color tables (global and local) with black for all remaining spaces. I realized this after discovering that may decoding implementation was wrong, which was causing issues when hitting the repeated "black" (#000000) color codes.

            More information can be found in the spec itself, located here:

            Using `jsgif` to build layers over animated GIFs
            Asked 2017-Aug-09 at 05:31

            I'm looking to get some help or guidance on the use of the excellent libgif.js library.

            My objective is to take a page that has an animated gif and a png of text with transparent background, and then show the 2 images overlaid such that the resulting image can be copied to the clipboard.

            I've familiarized myself with the libgif.js library and have succeeded in using it to build a canvas from an animated gif and have it remain animated.

            However, the text image is not being displayed in the final canvas, and I'm a little lost as to how I might go about fixing this.

            Is it obvious to anyone why the textImage is being properly sized and (somewhat) apparently placed on the canvas, but not displayed in the final result?

            As a side question, does anyone know why the progress bar completes quickly at first and then progresses more slowly a second time?

            The HTML is rather long, but the JS from the JSFiddle is shown below (for those not willing to click through to the link).

            You would have to tweak the library in order to get access to their rendering loop (like a frame_rendered event).
            This way, you would be able to add whatever you want over the image the library drawn at every frame.

            But since I'm too lazy to dig in there, here is a workaround :

            Instead of appending the canvas returned by the library in the document, you can keep it offscreen, and draw it on an other, visible, canvas.
            It is on this new canvas that you will also draw your textImage, in an rAF loop.

            Headless Chrome: Run a webpage from command line without launching it?
            Asked 2017-Apr-30 at 16:29

            I have a webpage that uses D3, canvg and gif.js to generate GIFs of time-lapse maps. The page generates 3,000 gifs, one at a time. The page is not meant for public consumption.

            While it works pretty well to just open this page and download the GIFs, it tends to be asking a lot of the browser. So I'm curious if there's a way to run a page headlessly from the command-line without actually opening it, but running the full app to render the page.

            Why not just use Phantom from Node, you might ask? For starters, Phantom is hard! But more importantly, I've never had complete success using Phantom or any other client-side browser engine, like jsdom, to completely render SVGs exactly right.

            So my question is basically whether it's possible to use Chrome instead of Phantom and launch a page from the command line that executes the page as if it was merely opened in the browser but without actually opening the page.

            Thanks!
