This is a pretty general question but just looking for someone to get me started in the right direction. I have been given a project where I need to create maps on a webpage and have certain parts of them highlighted/outlined on mouseover.
The maps I was given are illustrator files and when I open them up I see they are divided into the areas that I will need to highlight. Do I get those paths from AI and use them with something like Raphaël? Or do I create some overlays? Really not sure how to get started here.
Illustrator lets you export as svg. you can then use the svg as a background image, or include it inline in your page.
Note that you dont necessarily need to keep it in vector format in order to use it on a webpage. You could also simply use illustrator's "Save for web" feature to export the graphics as a png or gif.
Either way you can then start working with it like any normal web resource to build your page.

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.

Thanks in advance!
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.
I need a javascript library for manipulating/processing images. Not inside DOM, but similar like GDI+ where I can pick an image from file system and manipulate it programatically (get pixel color, change pixel color, add shapes and text , etc..).
I searched goolge but couldn't find such library. So far the best thing I could only find is a library called jimp, but it seems very basic and high level.
Does Javascript have such capability? reading an image and extracting information from it?
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'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'm trying to render these files http://registro.soveci.com/dom_izq.svg and http://registro.soveci.com/dom_der.svg with RaphaelJS and raphael-svg-import, but somehow a path appears misplaced on the screen. If you view it with a standard compliant browser, you can see the path being rendered right, so it must be a problem with raphael-svg-import.
Can you provide me some hints??? (I'm new to SVG)
I have been experimenting with SVG for a little bit now and it's a bit of a coincidence because I just finished playing with that plugin today.
The url to a demo I have there also contains zip files in the documentation so you could experiment with these in Inkscape or any SVG editor and see if you cannot configure them to something in your project.
For what ever reason this plugin "likes" some SVG's but not others so maybe you could adapt one of the SVGs in the zip and it will probably work.
The authors know the plugin does not always work but it is gradually improving and even now I think it's possible to write compatible SVG's if you tinker with them.
If you need a facility to convert certain SVG's just to javascript you could use this.
