I'm trying to switch out the SVG images I am using to PNG on browsers that don't support them - namely IE8/7 and old versions of Android.
After a lot of looking, I think I've found the tool for the job - svgeezy - The issue is, I have no idea how to use it! (I don't understand the tiny documentation given)
I'd really appreciate it if someone could explain it to like I'm two, I ahve no idea where to begin (I'm new at this) :)
p.s - I know there are other ways of doing it, but I was having all kinds of trouble with using the SVGs as a background, I want to avoid that way of doing it.
Thanks :)
Svgeezy's API is not all that intuitive or powerful, but it's simple. The first parameter is the class name you want to avoid replacing (if any) and the second is the type of fallback. This works at the document level, so you can't replace some SVGs with JPG and others with PNG.
// will replace all SVGs with PNGs
svgeezy.init('nothing', 'png');
// will replace all SVGs with JPGs except those that have class="noreplace"
svgeezy.init('noreplace', 'jpg');
Your fallback should have the same file name as the original SVG. So, for example, if you want to replace logo.svg, then logo.png should be in the same directory.
To load the javascript put this just before the closing </body> tag:
<script type="text/javascript">
svgeezy.init('whatever', 'png');
</script>

I have a site that is using fontawesome. I am lazy loading many of the CSS files to increase first page load time, etc.
However, I need the fa-phone-alt to working on first load because it appears at the top of the page.
Can anyone provide guidance as to how I an add inline style just for the fa-phone-alt so that it works without having to load the entire style sheet?
Hope I am explaining this well enough.
Thanks.
I'm not sure how to solve exactly what you're asking, but a workaround could be that you download an SVG of a phone and place it so it loads instantly.
I just started trying out the TideSDK to deploy a website to .exe and .app, which for the most part is fantastic.
The problem that I'm currently coming across is that all my CSS styles are written in .less styles utilizing the less.js framework. Inside of here, I have custom font-faces declared, and when deployed to a standard web browser, they apply fine to all the elements that use them.
When deployed through Tide, it doesn't seem to stick unless I take all my styling out of .less style sheets and put them back into regular .CSS files, which leads me to believe that there is some sort of compile time change that Tide is using internally when deployed the actual view of the application.
I have no idea how to go about fixing this. As a note, I'm not getting any
[Error] Error finding
errors from the Tide console, which leads me to believe that the .svg's are being found, just not applied.
UPDATE:
It seems I was using wrong syntax in the src: url('...'), so the CSS in the .less file was actually failing silently. I'm getting a pretty strange [Error] Error finding... file for the .svg now. The URL that is inside this line of CSS is being prepended by app: 3 times.
After several hours of looking at this problem, I eventually have figured it out. Couple of things to note when you are using the combination of these frameworks:
less.js spits out really odd path directories when using
src: url('...');
As a solution for this, you can use the import directive that is available to you in less and put the #font-face declarations inside of that .css style sheet. By importing a plain .css style sheet, you are telling less.js to treat it as regular .css, and the muxed url that gets spit out won't happen.
#import "../css/style.css";
After putting the import directive and confirming that the SVG was indeed being generated under Resources - Fonts in the Chrome inspector, I proceeded to take a look at the SVG file itself to determine if there was something wrong in the CSS naming conventions for the SVG file. According to this answer, and the blog post within it, your SVG name should be using:
font-family
value in the naming scheme from the SVG meta data
src: url('YourSVGFont.svg#Silkscreen') format('svg');
when in fact, you should be using the font id, at least that was the solution in my case:
src: url('YourSVGFont.svg#slkscrb') format('svg');
This is the image embedded in the blog post so that you can see what I'm talking about, and see where in the SVG meta data these two names are placed.
I am trying to create an interactive map where users can click on different provinces in the map to get info specific to that province.

So far I've only found solutions that have limited functionality. I've only really searched for this using an SVG file, but I would be open to other file types if it is possible.
If anyone knows of a fully functioning way to do this (jQuery plug-in, PHP script, vector images) or a tutorial on how to do it manually please do share.
jQuery plugin for decorating image maps (highlights, select areas, tooltips):
http://www.outsharked.com/imagemapster/
Disclosure: I wrote it.
Sounds like you want a simple imagemap, I'd recommend to not make it more complex than it needs to be. Here's an article on how to improve imagemaps with svg. It's very easy to do clickable regions in svg itself, just add some <a> elements around the shapes you want to have clickable.
A couple of options if you need something more advanced:
http://jqvmap.com/
http://jvectormap.com/
http://polymaps.org/
I think it's better to divide my answer to 2 parts:
A-Create everything from scratch (using SVG, JavaScript, and HTML5):
Create a new HTML5 page
Create a new SVG file, each clickable area (province) should be a separate SVG Polygon in your SVG file,
(I'm using Adobe Illustrator for creating SVG files but you can find many alternative software products too, for example Inkscape)
Add mouseover and click events to your polygons one by one
<polygon points="200,10 250,190 160,210" style="fill:lime;stroke:purple;stroke-width:1"
onmouseover="mouseOverHandler(evt)"
onclick="clickHandler(evt)" />
Add a handler for each event in your JavaScript code and add your desired code to the handler
function mouseOverHandler(evt) {};
function clickHandler(evt) {};
Add the SVG file to your HTML page (I prefer inline SVG but you can use linked SVG file too)
Upload the files to your server
B-Use a software like FLDraw Interactive Image Creator (only if you have a map image and want to make it interactive):
Create an empty project and choose your map image as your base image when creating the new project
Add a Polygon element (from the Shape menu) for each province
For each polygon double click it to open the Properties window where you can choose an event type for mouse-over and click,
also change the shape opacity to 0 to make it invisible
Save your project and Publish it to HTML5, FLDraw will create a new folder that contains all of the required files for your project that you can upload to your server.
Option (A) is very good if you are programmer or you have someone to create the required code and SVG file for you,
Option (B) is good if you don't want to hire someone or spend your own time for creating everything from scratch
You have some other options too, for example using HTML5 Canvas instead of SVG, but it's not very easy to create a Zoomable map using HTML5 Canvas,
maybe there are some other ways too that I'm not aware of.
Just in case anyone will search for it - I used it on several sites, always the customization and RD possibilities were a perfect fit for what I needed. Simple and it is free to use:
Clickable CSS Maps
One note for more scripts on a site: I had some annoying problems with getting to work a map (that worked as a graphic menu) in Drupal 7. There where many other script used, and after handling them, I got stuck with the map - it still didn't work, although the jquery.cssmap.js, CSS (both local) and the script in the where in the right place. Firebug showed me an error and I suddenly eureka - a simple oversight, I left the script code as it was in the example and there was a conflict. Just change the front function "$" to "jQuery" (or other handler) and it works perfect. :]
Here's what I ment (of course you can put it before instead of the ):
<script type="text/javascript">
jQuery(function($){
$('#map-country').cssMap({'size' : 810});
});
</script>
Go to SVG to Script
with your SVG the default output is the map in SVG
Code which adds events is also added but is easily identified and can be altered as required.
I have been using makeaclickablemap for my province maps for some time now and it turned out to be a really good fit.
I had the same requirements and finally this Map converter worked for me. It is the best plugin for any map generation.
Here is another image map plugin I wrote to enhance image maps: https://github.com/gestixi/pictarea
It makes it easy to highlight all the area and let you specify different styles depending on the state of the zone: normal, hover, active, disable.
You can also specify how many zones can be selected at the same time.
The following code may help you:
$("#svgEuropa [id='stallwanger.it.dev_shape_DEU']").on("click",function(){
alert($(this).attr("id"));
});

You have quite a few options for this:
1 - If you can find an SVG file for the map you want, you can use something like RaphaelJS or SnapSVG to add click listeners for your states/regions, this solution is the most customizable...
2 - You can use dedicated tools such as clickablemapbuilder (free) or makeaclickablemap (i think free also).

jQuery(function($){
$('#map-country').cssMap({'size' : 810});

I am using Raphael to create a dynamic visualization. Is it possible to allow the image generated on the Canvas to be downloaded as a SVG/PDF or another image format?
There are pieces of information missing here, namely browser support, server-/client-side solution and whether costs are okay or not. So I'll try to give you an exhaustive answer.
For a client-side solution, you can use DocRaptor. Just feed the SVG tree to DocRaptor This works for the SVG-producing browsers (all since 2005 except for IE prior to version 9). Note that DocRaptor has a fee for converting documents into PDF. For a free server-side solution for converting an SVG tree to a PDF, I would suggest using wkhtmltopdf as proposed in this answer.
For IE6-8, which Raphaël produces VML for, you could create a PHP solution using the Vector Converter library. When the conversion from VML to SVG is finished, sent the SVG to DocRaptor (or wkhtmltopdf).
There is no free client-side VML/SVG -> PDF solution that works for VML or SVG. To build that would mean interpreting SVG and/or VML, creating a PDF from it using JavaScript (there are JS PDF library attempts), and sending it to the client using some Flash technique. I guess nobody has attempted to build that yet. I might.
pdfkit seems to be the way to go, with using browserify to make the node code run client side. There is a nice demo here
You can save as an image using canvg and canvas2image libraries

I made the following observation:
If I create an svg image that references an external raster image via xlink:href and try to load the svg in browsers, the external images are only shown if I use the <object> tag, but not when using the <img> tag.
Rendering with the <object> tag is quite slow and not as clean as using the img tag for images so I was wondering if there's a way to make it work through the <img> tag.
At first I thought it doesn't work because of a same origin policy, but even if the referenced image is in the same directory and I reference it through its name only, it wont load.
Any ideas?
Are you using IE? IE doesnt recognize SVG anyway. Microsoft is always ten years behind, yet they are more popular and far more costly, for some reason. Name brand propaganda?
SVG loads in Firefox. Both as an XML document referenced directly in the URL, and also if you embed it into an XHTML (fully XML compliant) document with proper namespacing, the SVG should render properly. The great thing about this option is that DHTML can manipulate your SVG. Everything I said in this paragraph also applies to MathML, if youre curious.
Aside from that, SVG doesn't load from an image tag. I do believe Firefox is working on this upgrade, though. Im not entirely sure.
Using the object or embed tag is reasonable, I suppose... but one of my earlier fixes was to use an iframe. Embed an iframe in your html that references the complete SVG file. Using CSS you can make the iframe look flush with the rest of your document, appearing and acting like an image. Encased in a div or span tag, you can have onhover and onclick event handlers.
Using the image tag, your src can be a PHP file on server side. If properly coded and with the appropriate cgi apps, you can rasterize your SVG on server-side, and have that PNG data sent back to your image via the PHP src.
There's no particular reason <object> should be any slower to load than <img> apart from possibly the interaction aspect (img's are static while object's are fully interactive documents). The images inside the svg should load in both scenarios, so it sounds like a bug in the browser.
Could you post a link to your example?
I think you are at least 10 months behind...IE9 supports SVG, and pre-release versions (including a beta) have been out for quite a while. Check out www.ietestdrive.com to grab the platform preview - it's pretty good. In my opinion, parts of their SVG support are much better than Firefox currently (but they don't support SMIL yet).
