I'm starting a project for browsers which requires some complex data processing. The algorithm I'm using is 50-100x faster when accelerated with GPU.
I could use JavaScript, Flash or other technologies with the browser.Is there any way I can access the GPU to accelerate the processing of my math?
I'm trying to figure out the extent of flash 10's GPU acceleration capabilities. Is it possible to get 100% of your code GPU accelerated, or is only certain sandboxed functions? Even if I have to go outside the browser to get it, or to know exactly how much and what kind of GPU acceleration I can achieve inside the browser.
View 1 RepliesActionScript3 states the following:
Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use.
My web application works with very large and small numbers that I suspect may see a difference depending on which machine is running it (especially with mobile devices whose processors aren't as powerful as desktop machines'). My question is, is this behavior a function of the language?
That is, I assume some languages implement their own algorithms for the above functions, and so may be more consistent (except for differences in round-off errors introduced by the choice of processor/CPU that would exist for all languages).
Anyone know if Javascript has it's own algorithms, or does it outsource them to the CPU/processor like ActionScript?
I'm wondering if its possible to do what I'm thinking, and if it is possible, does anyone know of a flash object that does what I need? I know a Flash object can provide a javascript API to interact with it, what I dont know is can Flash send an email directly without the need to talk to the webserver to do so? If thats possible would it not be possible to write a flash object that did nothing but provide an API to send emails? Has such a thing been created that is out there for others to use?
I'm looking to create a email form on a web page but the site is static (no server scripting). In my situation server scripting is not possible as there is no server, the site is 100% client side on a CD/DVD/USB Stick.
Here is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?
Wat is the diffrence between these two?

View 1 RepliesI am working on optimizing a page that has Flash on it. I am using optimization practices like moving Javascript to the bottom to not block. Removing inline scripts. And minimizing HTTP requests with minified css and js.The majority of the pages content is in the flash, so loading it as soon as possible is the goal. Currently there is a 2 ~ 3 second delay before the flash is even rendered (using firebug profiling)
I am wondering at what point in the page load does the browser start initializing flash on the page? Is it once the DOM element containing the flash has been rendered? Is it once the complete onload event has been fired? I imagine it probably differs with each browsers as well.
I need to plot a contour chart in the web browser. It needs to be interactive as well. Does anyone know good javascript library, flash or flex libary to do this?
View 1 RepliesI have a Flash application that sends a getURL request for an image file every 60 seconds.
This works fine in all browsers except IE9 with Internet Option set to automatically check for newer versions of stored pages. I setup Charles proxy (http://xk72.com) to watch the requests being sent by my flash app and confirmed that the request is being surpressed by IE9 when the setting is set to Auto, but works fine if I change the setting to check everytime I visit the webpage. This, however, is not an option! I need this to work in all browsers regardless of how the options are set.
Even if I do a page refresh (F5), the ASP page does not reload. The only way to get it to reload is close the browser and restart it.
I have tried adding content headers to disable caching but it does not appear to work.
For Example, here is my request headers:
HTTP/1.1 200 OK
Date Sun, 02 Oct 2011 23:58:31 GMT
Server Microsoft-IIS/6.0
X-Powered-By ASP.NET
Expires Tue, 09 Nov 2010 14:59:39 GMT
Cache-control no-cache
max-age 0
Content-Length 9691
Content-Type text/html
Set-Cookie ASPSESSIONIDACQBSACA=ECJPCLHADMFBDLCBHLJFPBPH; path=/
Cache-control private
I have read the Microsoft blog (http://blogs.msdn.com/b/ie/archive/2010/07/14/caching-improvements-in-internet-explorer-9.aspx) which states that if I add the content headers, the browser should respect my request, but it obviously does not.
I don't think this is a Flash issue since the html page that holds the Flash object will not even reload.
Ideally what I was initially looking for is an implementation of the HTML5 Media Capture API with a polyfill rolling back to Flash, however, my research has concluded that the API is in its infancy and is yet to be taken up by any of the major vendors, and in addition to that, Flash means for doing what I need seem scarce.

Can a SWF file, viewed locally in a folder on my PC, make a call to a function in a JavaScript file?I am facing a project where the technical architect is prescribing that all content exist in an all-in-one, giant JavaScript file. With my usual external content experience working with XML, I have always been able to load in XML into the SWF directly (for example, while viewing the SWF in the Flash authoring environment - a very speedy way to view your SWF), as well as when the SWF is actually viewed in the website. However, with the JavaScript approach, my only experience tells me that the SWF has to be embedded in HTML before it has access to the JS functions.

In Actionscript 3, I make a call to Javascript using:
ExternalInterface.call('javascriptFunction');
If in Javascript, there's an error or a blocking call, the entire browser will freeze. I can't use Firebug in Firefox to debug it because the act of stepping through the callback also crashes the browser. How do I go about debugging this?

I'm on an HP desktop with Windows 7, Firefox 5.0, IE9, and Chrome 12.0.742.122. Either alert call will randomly cause Firefox to freeze...it actually usually happens in bunches, where it'll freeze for a few times continuously (obviously restarting Firefox each time)..and then stop for a few hours and be alright.It has yet to crash IE9 or Chrome, though I haven't tested it as extensively with Chrome. Using the Firefox console doesn't help since Firefox just crashes all together. If anyone could shed some light on that, that'd be great!
I would like to do the following trick in a browser:
Create three image files of different size (small, medium, large) from one picture.
First, display the small image in a browser. When a user zooms in the small image replace it with the medium one. Now the user can scroll it within the window up and down, left and right. When a user zooms out the small image replace it with the small one, etc.
I would prefer JavaScript (Flash is the second option). What tool would you recommend ?

"With the recent new 10.3 player this should be much easier, since there are new events for this specific situation."

I have a website with a simple Flash animation behind some text and semi-transparent images as a background. I have used swfobject to embed it and set wmode opaque to make it display correctly in most browsers.For browsers without Flash, the user gets a static background image instead and would not know they were missing anything. However, Android users get the flash background on top of everything as per the known issue with how Flash content is rendered in the Android browser making the site unusable.
I have added a crude browser sniff javascript function to the swfobject code to prevent it from loading for any user agent whith 'Mobile' in it:
<script type="text/javascript">
if (navigator.userAgent.indexOf('Mobile') == -1)
{[code].....
The only problem I have left is for Android users browsing with 'Mobile View' turned off as the user agent pretends to be a desktop version of Safari (I think). I do not wish to disable the Flash animation for all Safari users. Is there a way of blocking it for just Andriod users - even if they have 'Mobile View' disabled?
Possible ideas include:detecting the Flash version with JavaScript or Flash. Does Android use specific versions (version numbers) of Flash which are different from the desktop equivalent? blocking the specific user agents used by Android devices with 'Mobile View' disabled.
My webpage loads a background flash which will connect to the server using socket. If a user open multiple windows/tabs of my website, the server will get multiple socket connections. Any idea of how to make sure that only one socket is connected from the same user and same browser?
I am thinking of using Javascript to monitor the window close event, if a window that was connected to the server is closed, one of the other windows will try to connect to the server. But I can't find a way to listen to that event.I was thinking of Flash's LocalConnection too, but can't find a way to assign unique connection names and let other Flashes know.
do you know any browser-side component, in HTML/Javascript, Flash, Applet or Silverlight, that would allow source code edition with syntax highlighting and auto-completion.

Currently I'm searching for a free solution to simple edit some photos at the users browser. Resizing and Cropping would be mandatory. I'm not searching for an online service (for example SUMO or PIXLR which are great), because I want to include the software into a WYSIWYG Editor. JavaScript would be really nice, but it would have to work in IE 8. Pixastic is a great example, but works only in modern browsers (not IE 8 :-/) Maybe setting up some kind of image processing service with ImageMagick and communicating with it through AJAX could also be an solution? Has anyone gained some experience with such a solution?
View 2 RepliesGoal: I want flash to have accurate information about the width and height of the browser viewport in device pixels when intializing, resizing, or on browser zoom events.
Specifics: I need to embed flash into an html page that runs in chrome, safari, firefox, ie. The swf must fill the entire browser viewport.I don't want the flash to zoom.Inside of flash I can set StageScaleMode.NOSCALE so that flash renders to Device Pixels.I also set the state's alignment to StageAlign.TOP_LEFT.Now all I need is the number of device pixels in the browser!
Problem: when there is a browser zoom or I open the site while the browser is zoomed, I cannot easily get information on the browser's dimensions in device pixels.
Solution: acrobat.com's online document editor (formerly known as buzzword) handles this problem just fine (free to play with with an account).What are they doing?In webkit browsers, they are able to keep the document.width to report device pixels every time. I am not sure what they are doing in firefox and ie.
What doesn't work:Swffit does not support this.Just loading the swf into the browser is not a solution, as the swf needs to be embedded.This solution scales a swf to accomodate different browser zooms but does not get information on the browser window dimensions.
I was wondering how to achieve the native scrollbar effect which TheFWA (thefwa.com) has managed to do pretty well (I am not a fan of Flex scrollbars).and implemented the technique, as I am calling a JS function through ExternalInterface every time, when the flash object changes size. This JS function simply resizes the div which holds the flash object, which creates the native bars.Unfortunately, when I resize quite rapidly (from 800 to 1800 height, for instance) the flash object simply gets warped for several milliseconds (as if it hasn't changed its size, but simply got pulled in all directions). After these milliseconds, things get back to normal, but the whole situation is really visually annoying.
Originally I thought that it's simply a timing issue, but after a bunch of attempts to set a delay, the effect was the same ... just delayed.How can I resolve that? I know it's technically possible. Just take a look at TheFWA, and see how smoothly flash and the browser are communicating with each other to make the native scroll bars work, without any flickering, or mismeasurement

I'm working on a project that originally required me to use <area> elements and 40 copies of a single GIF image to have a hoverable and clickable <img> tag. I suggested SVG, and the client agreed to use SVG instead, as it was easier to work with for both of us.
Anyways, my question is, what cross-browser JavaScript SVG library will allow me to display and interact with pre-made SVG images.
I know of these libraries:
Raphaël: I'm currently using this along with a SVG loading plugin. But that plugin does not support Inkscape or Adobe Illustrator SVGs (i.e. most SVGs). cang: This library looks promising, but it requires <canvas> support, which IE doesn't have natively. svgweb: Another more-promising library. It requires Flash, but most IE users have Flash. jQuery SVG: It seems to be able to load SVG images, but development seems to have died. And it requires me to use a modified version of jQuery 1.3.
My client would like to provide somewhat-arbitrary images to my script and have chunks of them be "selectable" (see my demo here).
