[Flashcoders] flash changing size on mouseover
Hi FlashCoders, I'd like to make a flash movie that displays small most of the time but when clicked, or on mouseover, it opens up big (either covering up the rest of the web page - which will be standard HTML - or shuffling down the rest of the web page). This isn't for a banner, but I've seen it used with some advertising banners. Could someone tell me if this is something done in the flash, or is the actual resizing being done by javascript? Is there a standard name for this technique, as my googling is not turning up much. The closest I've seen is this: http://www.flashdesignerzone.com/tutorials/t1020.php But (in firefox with linux flash 9 plugin) that simply does not work - I see a big white rectangle for the expanded size, and it is covering up the text in the web page!

Re: [Flashcoders] Drawing pie charts?? (using Flash MX)
A month ago, Boyd asked: Anyone know where to find algorythms or code scraps that would let me draw pie graphs using dynamic data? I am using the older Flash 6. And, also a month ago, Eric Dolecki asked: Q: Has anyone seen a dynamic pie chart component that allows one to add slices with code, remove them with code, and also allows one to click and drag edges of slices around to allow a user to manually change the % data for slices? Then, nearly a month ago, Millie Niss asked: Are there good free charting (I need customizable bar graphs and line graphs of small data sets) components or class libraries? ... I would prefer not to have to learn an entire framework just to get the charts, and I definitely don't want something that weights down the published swfs. Sorry for the late reply. dcflash is an open source ActionScript 2 library with a main focus on charting (also support classes for storing time series data, statistics - especially for financial charting, back-end connections, etc.). Version 0.1.0 was release a month ago. Some chart styles are still to be brought in, but the pie chart class is quite solid and quite advanced. You can see my pie chart demo here: http://dcook.org/work/charts/pie_chart_demo.html To Boyd: all classes in the library work with Flash 6 (the above demo is Flash 7 solely because of using Aswing for the UI). To Eric: you can add/remove slices easily enough (modify the data array and redraw). Support for mouse actions is not in yet, sorry. (Actually, I've never seen an interactive pie chart like you describe - are you free to describe the application?) To Millie: for simple bar charts look in the Line/Shapes classes for the drawVerticalColumns(); for line charts look at drawLinesToRight() and drawMountain(). More complex charts, will be in the 0.3.0 release, a month or two away. Some other examples of what the library can do, or will do Real Soon Now: http://dcook.org/work/charts/ The library is hosted on sourceforge, here: http://dcflash.sf.net/ Please join the users or announce mailing lists if interested!

[Flashcoders] Re: [osflash] OpenSource Data Charting framework wanted ?
I'm currently search for an OpenSource Data charting framework,... I've been working on such a library for a long time, with the intention to release as open source. I've a sourceforge page set up ( http://dcflash.sf.net/ ) and some demos (links and screenshots on the SF page), and am in the process of preparing the code for a first release. There is also some code for statistics (with a financial charting emphasis), and also client code that ties in with a PHP XML server (also open source) that eases the pushing of financial data for charting (though is more general than that). Nagging me to get the release out the door will probably be effective, so let me know if you are interested :-).

Re: [Flashcoders] Flash 9 ready for kiosk use?
he was able to publish as 7, so he's having some other issue and I'm willing to bank that he is experiencing memory waste (a leak is different) ... No: the flash player is able to correctly delete the memory when I minimize then maximize the window. If I was still somehow holding on to a pointer to the memory (which was my original thought too) it would not be able to do that. Or in other words, whatever additional clean-up it does when I minimize the window it should be doing when running normally, every 10 seconds or something. It doesn't, even after running for hours. Therefore I describe it as a bug. It sounds like Flash 9 may have fixed that bug; hopefully my client will request a Flash 9 version and I can find out for sure.

Re: [Flashcoders] Flash 9 ready for kiosk use?
I've just downloaded the Adobe Flash 9 Public alpha and used it to compile one of my old kiosk projects. As far as I can see it has none of memory leak issues which affected Flash 8 and stopped it being suitable for kiosks. This is great This is very interesting. Is it just a matter of loading a Flash 8 fla, and making a Flash 9 swf? Or would we need to convert from AS2 to AS3, etc.? I have no idea what memory leak issues you're talking about with the Flash player. ... There is one described here: http://www.gskinner.com/blog/archives/2005/10/major_flash_pla.html And the one I've had problems with described in the thread here: http://chattyfig.figleaf.com/pipermail/flashcoders/2006-March/161859.html Beyond what is written there I convinced myself it is a player bug simply because it will correctly free up all memory if you minimize then maximize the player window. Without doing the minimize/maximize trick it seems like it does not do certain types of garbage collection (but it does garbage collect something, as I see the memory usage wobbling up and down).

Re: [Flashcoders] server-side FLV encoder ?
are there any linux tools that can use a PHP or command-line interface to batch convert incoming files to flash video? ffmpeg is probably what you want: http://ffmpeg.sourceforge.net/ Note that it can only convert from/to the older flash video format (i.e. the Flash 7 format). what is needed to serve flash video? is apache OK? I believe so, and I believe it streams (i.e. it starts playing before the flv is fully loaded).

Re: [Flashcoders] Find Nearest Color?
Hi,
A minor optimization, but you can drop the Math.sqrt(). I.e.
x^2 y^2 == x y
for all positive values of x and y.
Darren
That's what I actually ended up doing, and it worked out pretty good:
private function getClosest (red1:Number, green1:Number,
blue1:Number):Number {
var totalColors:Number = __palette.length;
var tempDistance:Number;
var closestColor:Number;
for (var i:Number = 0; i totalColors; i++) {
// first, break up the color to check
var red2:Number = (__palette[i] 0xFF) 16;
var green2:Number = (__palette[i] 0x00FF00) 8;
var blue2:Number = __palette[i] 0xFF;
// now, get the distance from the source
var tempD:Number = Math.sqrt ((Math.abs(red1 - red2) ^ 2) +
(Math.abs(green1 - green2) ^ 2) + (Math.abs(blue1 - blue2) ^ 2));
if ((tempD = tempDistance) || tempDistance == undefined) {
tempDistance = tempD;
closestColor = __palette[i];
}
}
return closestColor;
}

If a color can be treated as a point in a 3-d cube 256 units on each

to calculate the distance between 2 colors.
I have not tried this but it would seem logical that this would work

K, here is some better math for getRGB, performance will probably be
important:
return [c16, c8~0xFF00, c~0xF00];
You can also try using the ColorTransform or Color class to get the rgb
values, except they might be slower than getting the raw math right.

I tried comparing the hex values directly, but there were

maybe the same ones you've been having. I think since the value of a
particular color precedes with a 0 even when it's below 17(0F), the
preceding 0 causes a shifting in the comparison. It would, for
example,
cause 0x00 to seem farther to 0x123456 than 0x00FF00, where
visually you
can see clearly that black is closer to 0x00.
btw in my example, var a = 0x12345 where it should be 0x123456.
The numbers hold to be accurate after correcting this typo.

Does anybody know of any formulas available for comparing multiple

searching Google for a while, with no luck. Any good resources on
color formulas such would be appreciated.

Re: [Flashcoders] If not Zinc, then what?
I always had this feeling Flash is not meant to be run for a long period of time - no one will interact with your Flash movie on browser for 24 hours continuously, so that's absolutely fine. But can anyone tell me if you have successfully developed 24/7 app using Flash wrapped in Zinc/SWFStudio/mProjector/Screenweaver without having issues such as memory leaks? Conversely I've started using a projector (screenweaver) for a 24/7 application because flash has a memory leak. The leak is simply that the garbage collector is not freeing everything, and it is easy to see it is the flash player's problem because minimizing then restoring the window *does* free up the memory. It happens with both Flash 7 and Flash 8 (only analyzed on windows XP). See flashcoder's Memory leak in Flash projector thread for more background (feb 25 2006 and mar 14-16 2006). I had two options: 1. Use a projector to a minimize then restore the window. 2. Start a 2nd application window, initially hidden, then when ready, close the 1st application window, then make the 2nd window visible. I needed a projector to be able to make the application hide/show itself and be hidden initially. The 2nd option is more complex but I chose it as then I can be sure it avoids any memory leaks that the minimize/restore trick does not; and because I was concerned about the desktop appearing briefly using the first option. (The PHP back-end was already controlling the creation of the flash front-end so I had much of the logic already there.)

Re: [Flashcoders] Memory leak in Flash projector
There was also a utility that someone on the team found that would force it to release the memory. But it was Windows only, and we had to support Mac so we ended up taking it out. Do you have a link or a name for that utility (I only need to support windows in the current project so that may do the trick)?

On Feb 25th 2006 Andreas Rønning wrote: This is very serious. The majority of my work is kiosk apps. Any more details on this, official Macromedia stance on it? Future fixes? Does anyone have more information on this? For instance what kind of features or media types or actionscript are causing the leak? We have a flash 8 application that has to be able to run for months without rebooting, but was leaking memory at 31Mb/hour! I realized I still had a textarea logger running but having removed that it is still leaking at 5MB/hour. We've tried running it as Flash 7, and also tried disabling all flv movies, but it still seems to leak at the same rate. Does that sound like something wrong we're doing in the actionscript (e.g. somehow holding on to references so stopping the garbage collector freeing the memory?) or like a player bug? Is there a way to force the garbage collector to run? (our application often has the CPU near 100% - I wondered if garbage collection only happens when the CPU is quiet?) Has anyone seen the memory leak go away when switching to zinc or a similar projector?
