I'm currently working in an Angular 4 app which has to display an image in which anyone could mark a point and add a text, I've seen a lot of Jquery Plugins that do the work, but I don't like the idea of combining Jquery and Angular, anyone knows about an angular component that works for generic pictures?
A quick google search, brought up this tool, which seems to have the functionality you want, though may be a bit overkill. I haven't used it myself, so I have no idea how well it works: https://www.npmjs.com/package/ng2-photo-editor
Alternatively, using the canvas API isn't too difficult for something as simple as overlaying text and marking some points. This tutorial seems to go through some of the basics: https://objectpartners.com/2016/09/22/using-the-canvas-api-in-angular2/

I know that this question sounds like asking for suggestion which should not be here, But I am posting after searching a lot for my requirement.
I am using react-router-native for navigation which is great functionality wise. But comes to the animation part, it doesn't give the best user experience. Official Documentation doesn't seem like providing any animation information.
Even in the google I found some articles(A shallow dive into React Router v4 Animated Transitions, Animating Route Transitions with React Router) describing about animation for navigation but only for react.
Hence, Could anybody let me know that is there any way to apply animation for react-router-native?
The standard place to start is exploring basic Animations. That said - have a look at one of the more developed transition libraries out there e.g. react-native-transition.
If it's specifically for just routing then there is a great answer Here.
You might want to try this animation library for react-router-native:
react-router-native-stack
I think you need react-router-native-animate-stackreact-router-native-animate-stack
yarn add react-router-native-animate-stack
This is by default swipeable and you can customize the transition when move to next page.

Currently I am trying to build such customization of product in Bigcommerce Storefront that allows to display image with dynamic text, which was entered in Textbox. That means product image preview should be shown INSTANTLY with new image with written text.
so that the end user will know how the final product will looks like and also same image should go in shopping cart as well.
I know that there is an app on Shopify named as Product Builder.
Is this possible to do it on Bigcommerce?
Thanks in Advance
It's definitely possible with some fairly advanced client-side code. Unfortunately I don't know of any plug and play systems or apps for Bigcommerce that will achieve what you're looking for, but there are a couple ways to get a live updating product preview if you're willing to get your hands dirty.
Here's an example from my site. Click the button under "personalize this item", and you'll see a live preview image like you describe in the modal. Enter some text and change the monogram style and color, the preview image should update pretty quickly every time you change an option. A solution exactly like mine may not be feasible for you, since that site is using a pretty complex React/Redux implementation built on an extensively customized Stencil theme... it's far from a turnkey solution. That said, you could implement something similar without needing a totally custom app.
The image preview itself in the example above is powered by IMGIX.com. They offer a great service at a fantastic price. Basically my system translates the user-selected Bigcommerce option into a URL string per IMGIX's URL-based API. Displaying the live preview is then as simple as changing the image's src attribute to the corresponding IMGIX URL on every input change. I do this in a React component that consumes a Redux store, but something similar could definitely be done in the framework of your choice, or plain old vanilla JavaScript. Cloudinary offers a similar (maybe even a little bigger) feature set to IMGIX, but I found IMGIX to be a bit faster, and the pricing was considerably less for my usage.
You could also write something that uses the HTML5 canvas to overlay text and effects on an image, and thereby avoid using a third-party service. I found such a solution to be way more work and way more taxing on the client-side device, but it'd definitely be another way to skin the proverbial cat.
There may be other viable solutions out there, but the above has been my experience in implementing something similar to what you're looking for on Bigcommerce. I hope this is helpful!
Am trying to show multiple Bar Charts using Jfreechart API on a single page, all the charts from the same domain. Wondering if it would be better to use iFrames or are there any other alternatives? If i were to do this with Ajax, something like on page load show the bar charts in each div's, what would be the way to go about it? Would highly appreciate if anyone can throw more light on this.
I would recommend Flot for web-based charting even over my own open source API XChart, which is geared more towards desktop applications. Here is a HelloWorld type example application with source code demonstrating Flot that I made at one point. If more you're more interested in fetching a JPEG containing a chart, you can see how I do it with XChart (Bonus Example, bottom of page), and you could probably do something very similar with JFreeChart.
This question is more philosophical than technical.
I've trained myself as a web developer back when web developers were called webmasters and my tool of choice was FrontPage, moving onto Evrsoft 1st Page 2000.
That was the last time I used an HTML image map.
Now it's HTML5, AJAX, vector canvasses, CSS 3D, jQuery, local storage, touchscreen Safari, you name it. The image map has faded into an obscurity where not even Google comes up with too many relevant results; a mandatory W3C Schools entry and some forum posts from 2004.
Obviously creating a website navigation or similar triviality using an image map was a bad idea back then and it certainly is inexcusable today.
But right now I have a task to create a polygon clickable area on top of a div with a background image.
I'd have no issue doing this in image map since it seems like it was designed for a use case exactly like this, and while I've done no tests, I couldn't imagine any browser dropping support for an element that worked beautifully for years. But I can't help but think that there must be a better way to do this today.
My web creation philosophy is to develop for IE5.5, and then design for Chrome edge. This means that the site first needs to work on a basic level on even the most antiquated browser, and then start adding JS & CSS to make it more beautiful, more usable, faster, simpler, friendlier and better.
As such, while I know I could do a canvas in Raphaël and add all kinds of snazzy hover effects and things, I think making functionality as simple as this shouldn't require a 89 kb (or X kb) JS library. Or even JS at all.
I don't know if CSS3 has capabilities to define polygonal areas, but while recognizing the great possibilities introduced by CSS3, I prefer keeping anything defined there as non-essential flair that would degrade gracefully.
So in today's webdev world, what would be the most cross-browser way to define a polygonal click area (preferably in a way that's grabbable by a jQuery .hover(), or at least a CSS :hover), that isn't dependent on JavaScript or CSS attributes available in a minority of browsers? Is image map really the only way to do it? What of mobile devices?
Why is using image maps for navigation inexcusable? It's a tool like any other; it has a time and place. Using imagemaps with javascript enhancements is backward compatible, degrades gracefully, and has 100% browser support. They don't need a plugin like flash.They've been supported practically since the dawn of the web browser. Just because something's old doesn't mean it isn't useful; quite the opposite, it means it's well supported.
I wrote a jquery plugin called ImageMapster to add effects to imagemaps so you could create interactive images without using flash. It would be easy to implement a tool that had the same functonality without Javascript support by replacing with a list in those cases. Personally, I think trying to write for the web without javascript is like trying to drive a car without tires. 99% of the web doesn't work without it any more. This isn't 1995. But if you really are concerned, the nice thing about imagemaps is the basic navigation functionality still works. There's no way to accomplish that just with CSS -- not even CSS3 if you have irregular shaped areas.
Does anybody know of a good client-side gauge control? I've tried out ComponentArt's AJAX control, but it's client-side feature leaves a little to be desired. I'm not looking for a Silverlight or Flash gauge either. Currently, I'm playing around with Google's Visualization Gauge and it seems to work pretty well. However, I'd like the control to be more skinnable/customizable if possible.
Any recommendations?
assuming you're willing to write for HTML5 browsers...

Otherwise, make a DIV with a background image that contains another image that you use jQuery to rotate a-la
