I found a lot of resources about my question, but I'd just like opinions based off of a high level overview of what I'm trying to do.
Basically, I'm using a combination of Javascript, and HTML to build a customizer for a friends' website. I should start by saying that I have some HTML experience but this is the first time I'm using Javascript (I am experienced with Java). The ultimate goal will be something like a customizer to allow users to select the parts of a bicycle and change their colors to place custom orders.
I've got the various parts of the bike as images files, and I'm using this jscolor color picker found at: http://jscolor.com/examples/#example-showing-hiding to allow the user to select a color from the color map. My plan is to layer a given part (photo) on top of a copy of the same photo, and fill only one of them, like layering in Photoshop. This way, the part fills in the correct shape, instead of filling as an entire square of the image file. As the cursor moves, the color should change in realtime. Once done, they can save the part and the color record will be kept on the back-end.
As I'm new to Javascript and not that experienced with HTML, I'm finding it a bit challenging to get this on the right track. So I'm hoping for some advice from some people who are experienced with HTML/Javascript/CSS to point me in the right direction to get this going along a better track than it is currently. I wasn't sure how to "phrase" what I'm trying to do.
The three main parts I'm addressing:
Using HTML buttons to load a different bike part (essentially load a separate image file).
Adding the color from the jscolor picker to the image of the selected part.
Saving the state of the part when the user clicks a Save button.
I will continue to search the forums as I already saw a few leads similar to what I want to do, but I mostly want to know if my approach seems feasible for what I'm attempting to do.
Thanks in advance!
Using normal HTML buttons will make things complex for you.
I think leveraging HTML5 Canvas API is a better way to approach this problem. Canvas is the HTML5 element for helping out you do the graphics manipulations using JavaScript. Learn more about canvas here.
You can make use of a library such as Fabric.js to make things easier.

I would like to know the best web technology/js library to achieve this functionality. I need to change the colors of specific objects inside an image. I need to develop a tool where they can choose a color and the objects inside the image will turn into that color.
This is a very close example of what I need. I've been reading about canvas but I haven't been able to find anything close.

There are no magic or elaborated algorithm on it. They simply are using some PNG images and then they put the style tiles images before, so it looks like a texture changed or like if they uses a filter. You can realize of how it works watching the source code
The simplest way to target specific objects ( wall tiles, tables, floors, etc. ) within an image is in post production with an image editing application such as Photoshop, Artweaver, Paint.net, Inkscape, etc. and switch out images upon user selection using CSS or JavaScript. You replace the entire image this way and the minor changes show through when the image is switched.
If you don't want to do this manually there is no easy programmatic approach. For more information on coding applications to recognize objects look into machine learning and shape recognition algorithms but I suspect that is beyond the scope of a simple web app.
Basically how do sites like picfont work? Or those cake design sites where you have a template and you insert your picture into the frame and add & stylise text to the textbox?
I have an invite ad for a programme, where people put their picture and name and send out a personal invite. So the graphics guy has done the template. Rather than having 1000 people send him their photos and names, I know it's possible to put the template on a web page and have people upload their pictures, do some custom edit and stylise their names.
HOW do I do this, please? I would like some pointers or code I can implement, please. Thank you.
As mentioned, you will need the <Canvas> element for this, but this needs some custom development as well.
I took the liberty of creating a good starting point: https://jsfiddle.net/Zomry/f8to2fyq/11/
This demo loads a background image, can insert a custom image (assumed to be square here) and allows the location of custom text.
You can change this example to whatever you like. You will need to change the background, the positions of the text and the background and whatever you like to change with it.
Good luck with your project.
I'm currently working to develop a real estate website for a client. The client is stuck with the idea to create something like this :
http://woodfield-sillery.com/plans/
Basically, I'm looking to find a way to recreate the same thing, technically it would require :
Managing image map behaviour (to be able to react to mouseover)
Managing the onclick to open a view of the selected floor
Once selected, a second map would show of the floor, with available condos
Then onclick again, it would show pricing, availability, etc.
I'm having trouble managing the rollover image map through CSS.
Besides that, of course, the client would want to manage all by himself (so he can update the condo statuses), and I was planning to host the website through Wordpress
Questions :
Has anyone worked on a solution like this and would be willing to share experience?
Has anyone come across a Wordpress solution that works this?
Has anyone have a technical solution for this (Javascript, HTML5, CSS combined?)
I'm the author of MapSVG WordPress / jQuery plugin which is able to do what you need: http://mapsvg.com
To get started you would need to create a blank image in any vector editor (InkScape, Adobe Illustator, etc.). Then embed building image (png/jpeg) to the background. Then add shapes on top of the image and give them a transparent color fill (=rgba(0,0,0,0)). Save image as SVG, upload it to MapSVG map builder.
Everything else will be done in MapSVG Builder - colors, tooltips, popovers, links, event handlers, etc. See the demo.
you can use maphilight plugin
or you can use jvector
tutorial use link
I am reconstructing a massive collection of medical modules that were created in Flash. All of the modules are being redesigned for cross platform enjoyment (js and HTML5). I have been searching for a library or plugin that will add arrows(with rollover capabilities) and text above an image when the user clicks a button. I have had little luck.
The closest package I have found is Zoomify, but it's still not what I am looking for. They are asking for too much money for maximum development capabilities. I was really hoping to find a JQuery plugin or javascript library that would allow me to fully customize the interface. Here is a screenshot of an OLD FLASH module:
The red arrow corresponds to the link selected on the left. The new design is much more appealing but the underlying idea is the same, click buttons point to the objects.
If there is no such library or plugin should I create a simple javascript image viewer and store overlay coordinates in a database? Or is that overkill? I have hunderds of these things to do... maybe thousands :( Any help/direction would be greatly appreciated.
What you are asking for is provided by CSS, which enables one to place text directly on top of an image or other rendered HTML. The key CSS properties to investigate are:
position set to 'absolute'
values for at least two of top, right, bottom or left
use z-index to specifying layering/order
Lightbox is a good option "Lightbox is a simple, unobtrusive script used to overlay images on top of the current page. It's a snap to setup and works on all modern browsers."
i am building a workout website that tracks exercises. Each exercise has a mapping to a certain part of the body (bench press --> Chest)
I am trying to figure out a way to visualize this and i thought of the idea of putting an image of a person "highlighting" the affected muscles. Sort of like This:
(source: aquaviews.net)
Assuming i have found a good picture without any areas highlighted, is there anyway to dynamically "highlight" areas in a picture (the red section) with javascript (client side) or C# (server side) or do i need a seperate picture for every exercise?
You COULD overlay the the base image with SVG or a <canvas> element.
But then you have cross-browser issues, possible alignment problems, and probably a cheesy look.
I'd have an artistically inclined person do the highlights as a separate graphic for each exercise.
But rather than have these as separate images, keep/combine them in a single file -- as a CSS Sprite. Then you get a professional appearance, great cross-browser support and easy, minimal coding.
You can use css to position your links over said muscle group and use a rollover to show the highlighed part...
Edit:
Sorry I guess I should have elaborated. You can absolutely position the elements with CSS and use an image rollover to swap out that section of the image to the highlighted section of that image. You can either do this by putting each muscle group into it's own div and putting an image of the corresponding muscle group into the background image. Then swap it out on rollow over. or you can use z-index and absolutely position the rollover elements where they need to be and change the z-index when needed.
Interestingly enough, I used to be a personal trainer and I did this same thing but did it in flash. That's my recommendation.
However, if you want to do it with JS and CSS, Brock's suggestion of the sprites is likely the way to go.
What you could do, very simply, would be to have an image map that for certain areas called a js function to swap about the background image with the same version of that image with the highlighted sections. Rather than several small images, you have the same image but with one part highlighted.
One question though, will you be doing compound exercises that would require you to have two sections highlighted? For instance, an incline press would highlight part of the chest and part of the delts. This makes the whole proposition more complicated due to the specificity of your roll overs.
i think you seeking a way to do this without requiring separate images, and if so - the answer is No - you are going to need to create separate images for at least the highlighted areas. Short of perhaps using a CANVAS element which has cross-browser issues, I don't believe there is any way to impose a filter to an arbitrary region of an image element.
And even if you Could apply an alpha filter, you would still need the geometry of every shape, so the effort/work is perhaps the same...
Once you have the various images there are sundry ways to approach the problem after that...
This is a simple implementation as i have done this highlighting with a county map. Use an image map. Then find a highlighting script like (mapper.netzgesta.de) mapper.js. All you need to do is have a properly set up image map (image must be suuounded by a div) and a link to this script. The highlighting starts immediately. Please check the license. Ther are several other that scripts that use javascript css and jquery to achieve this same effect. Just research highlight image map in google. Sorry i cant give you a link to my implementation of this as it is on a secure site for work. Good Luck.
