Re: [Flashcoders] Weird getURL behavior
Setup a http proxy (like proxytrace http://www.pocketsoap.com/tcptrace/pt.aspx) on your IE and you can thus see exactly what is being sent -- compare the HTTP headers, the url, the responses, of a working page and a non-working page. You will see exactly what is happening and most likely find the cause of your problem. good luck! B. 2006/8/2, Merrill, Jason [EMAIL PROTECTED]: Did you check your webserver's access log and see what you get when getURL( ) runs? I don't have access to that unfortunately. Big company. :) But good idea, I'll see if I can cut through some bureaucracy to get that information. Another quick test is to change your .doc extension to .html and see what happen. Maybe your webserver is configured not to serve that file type? (doesn't seem like it since you can get it when you try it at the address bar) No, it doesn't happen on other people's browsers, or if I enter the URL manually, so that wouldn't be the issue. Thanks though. Test it on Firefox too and see what happen... Actually, my site doesn't appear at all in Firefox, not sure why - probably just the way I am writing out the embed tags from external Javascript, but this doesn't need to work in Firefox anyway... Thanks anyway for your ideas. Any other thoughts?

Re: [Flashcoders] Problems getting the brightness of a color returnedfrom getPixel
In other words, to make your above code to compute brightness work from a
value returned by getPixel(), just change the few first line of the HSB
method from:
RGBtoHSB = function(rgb){
var r = rgb.r
var g = rgb.g
var b = rgb.b
...
to:
RGBtoHSB = function(var pixelvalue){
var r = pixelvalue 16 0xFF;
var g = pixelvalue 8 0xFF;
var b = pixelvalue 0xFF;
...
...then call it this way:
var pixel = getPixel();
var hsb = RGBtoHSB(pixel);
then simply use hsb.b
Hope it helps explaining :-)
B.
---
you could even recode the method to just return the brightness alone (no
Hue, no Saturation): (NOTE: this has not been tested - I simply stripped
off the unnecessary code from the previous method)
function computeBrightness(pixelvalue)
{
var r = pixelvalue 16 0xFF;
var g = pixelvalue 8 0xFF;
var b = pixelvalue 0xFF;
var bright = Math.max(Math.max(r,g),b);
return Math.round((bright/255)*100);
}
If I understand correctly, this should return a number from 0 to 100
representing the brightness. Which is in fact only the highest channel
value. (scaled down to the 0-100 range).
2006/7/29, Zeh Fernando [EMAIL PROTECTED]:
Thanks very much for your response Martin but I don't understand it. I
don't
have three vars called R G and B. I just have a number which was retuned
from getPixel. Am I being stupid? I can't see how I should do what you
sugest. Pease explain a little further.
That number you're getting is a color. You're just seeing it in decimal
form, rather than hexadecimal form. It's the same thing. For example, the
value for white is either 16777215 or 0xff (the two are the SAME
number,
just represented in two different ways).
On 0xff, the first ff pair is R, then G, then B. Like when you have
html color, #ff.
To extract the single R G and B values from a color, simply apply Martin's
code to the color.
var color = 0xffc1e2; // or the one returned by getPixel, same thing
var r = color 16 0xFF
var g = color 8 0xFF
var b = color 0xFF
Then R, G, and B will contain the values for each channel, going from 0 to
255.
Calculating brightness from that is one whole different matter, though.

Re: RE: [Flashcoders] Problems getting the brightness of a colorreturnedfrom getPixel
hum, I guess you missed my last post(?)
Here's the code again:
function computeBrightness(pixelvalue)
{
var r = pixelvalue 16 0xFF;
var g = pixelvalue 8 0xFF;
var b = pixelvalue 0xFF;
var bright = Math.max(Math.max(r,g),b);
return Math.round((bright/255)*100);
}
And for an optimized/faster version, you could try something like:
function computeBrightness(pixelvalue)
{
// returns the larger value of r, g or b -- and scale it down to a 0..100
range.
var r = pixelvalue 16 0xFF;
var g = pixelvalue 8 0xFF;
var b = pixelvalue 0xFF;
var bright = (rg)?((rb)?r:b):((gb)?g:b);
return (bright/255)*100; // no rounding.
}
(Again, this is untested code -- but it looks like it should work).

HI Guys, Thanks very much to you all for your help and explanations. I
understood that the number represented a colour value but I now have a
much better understanding of how it does so.
In your opinion what is the most efficient way to retrieve the
relative brightness of that colour.
What I need is a value between 0 and 100 where 0 is black and 100 is
white and the numbers in-between represent the shades in-between.
What I am going to try is this.
Split the number into its components RGB
use this code which came from the Flash API project
//colorModel converter RGB-HSB
//returns a hsb object
RGBtoHSB = function(rgb){
var r = rgb.r
var g = rgb.g
var b = rgb.b
var hsb = new Object();
hsb.b = Math.max(Math.max(r,g),b);
var min = Math.min(Math.min(r,g),b);
hsb.s = (hsb.b = 0) ? 0 : Math.round (100*(hsb.b - min)/hsb.b);
hsb.b = Math.round((hsb.b /255)*100);
hsb.h = 0;
if((r == g) (g == b)){
hsb.h = 0;
} else if(r = g g = b){
hsb.h = 60*(g-b)/(r-b);
} else if(g = r r = b){
hsb.h = 60 + 60*(g-r)/(g-b);
} else if(g = b b = r){
hsb.h = 120 + 60*(b-r)/(g-r);
} else if(b = g g = r){
hsb.h = 180 + 60*(b-g)/(b-r);
} else if(b = r r = g){
hsb.h = 240 + 60*(r-g)/(b-g);
} else if(r = b b = g){
hsb.h = 300 + 60*(r-b)/(r-g);
} else{
hsb.h = 0;
}
hsb.h = Math.round(hsb.h);
return hsb;
}
to turn it into an object with three values hue saturation and
brightness and then just make use of the brightness.
If there is a better way especially a more efficient way I would
really like to know.

Subject: RE: [Flashcoders] Problems getting the brightness of a

You seem to be thinking of numbers as if they are stored like strings.
They aren't.
RGB colors are stored as 3-byte (24-bit) numbers.
For example, red looks like this in binary:
b
...which is the same thing as this in hexadecimal:
0xFF
... which is the same thing as this in decimal:
16711680
To isolate, for example the red portion, you can use SHIFT RIGHT () to
shift all bits to the right by 16 bits. Binary:
b 16 = b
Hexadecimal:
0xFF 16 = 0xFF
Decimal:
16711680 16 = 255
Generally it's a good idea not to presume that there may not be more
bits to the left, so you can filter them out using a bitwise AND (). To
explain, this better, here's how to extract the green value from bright
cyan (0x7F):
The binary value of the color:
0111
Split into colors:
0111
Shift right 8 bits:
10111b 8 =
In hexadecimal, this result is:
0x
In decimal, it is:
65535
Clearly this is too large, because it includes the red value. To remove
it, we use a bitwise AND.
b 0xFF = b = 0xFF
To illustrate, we are taking this value:
b (=0x; =65535)
...and doing a bitwise AND with this value:
b (=0x00FF; =255)
This compares each bit in the first number to each bit in the second
number. If both bits are 1 (on), that bit is 1 (on) in the result. If
both bits are 0 (off), both bits are 0 (off) in the result. So the
result is:
b (=0xFF; =255)
...which is, indeed, the green value of the color.
So Martin Wood's example (slightly edited):
var r:Number = color 16 0xFF;
var g:Number = color 8 0xFF;

Re: [Flashcoders] Attention Recursion Speed Experts
I am assuming this is for AS2 - right?
If you want speed that probably means you are dealing with a lot of data(?)
1- What is the typical recursion level?
2- What is the typical number of items?
3- What is the typical size of sub arrays?
In general making a function call is not fast at all. Better iterate than
recurse.
B.
2006/7/25, Steven Sacks | BLITZ [EMAIL PROTECTED]:
Is there a way to make this script any faster?
Array.prototype.flatten = function(r) {
if (!r) r = [];
var l = this.length;
for (var a = 0; a l; a++) {
if (this[a].__proto__ != Array.prototype) {
r.push(this[a]);
} else {
this[a].flatten(r);
}
}
return r;
}
This function takes an array and flattens it, meaning any nested arrays
will get flattened into a single array.
Example:
x = [a, b, c, [d, e], f, [g, [h]], [[], i], j];
y = x.flatten();
y [a,b,c,d,e,f,g,h,i,j]
Issues:
Array.reverse() and Array.unshift() are notoriously slow and any speed
gained from doing a reverse while loop would be lost.
I don't see how this script could be sped up, but I'm not a recursion
expert. The current speed increases I have are:
1) Single character variable names
2) this.length stored in a variable avoids computation every loop.
3) Most common if true (not a nested array) comes first
I'm not clear which, if either, is faster:
if (x != y) vs if (!(x == y))
That's the only other place I can see a spot for a possible speed
improvement.
Thanks!

Re: [Flashcoders] AS3, BitmapData and domain security
I am not sure this is relevant to the discussion but: Your proxy trick will not work to access resources from local machines within a client's NAT. The flash player could potentially access those since it is already located behind the NAT. What I mean is that the flash player might have network access to some non-internet-public stuff.

Here's an example: http://www.neave.com/temp/proxy.php?proxy_url=http://www.google.com/intl/en/images/logo.gif The image looks as though it's coming from my server but it's actually coming from a domain I don't have server-side access to.

In AS3: var request:URLRequest = new URLRequest(http://www.google.com/intl/en/images/logo.gif;); var loader:Loader = new Loader(); loader.load(request); addChild(loader); would work fine, but I can't use BitmapData methods on the image. If I replace the URL with the proxied one above, I'd be able to use BitmapData without any problem. As far as I can see, any potential hacker could use a proxy script like this so I don't see what security benefit there is apart from just annoying developers! I'm now left with two options: 1) either proxy the image so I can access BitmapData (which costs me bandwidth and is much slower than direct access, especially if you're accessing many images at once) or 2) don't use BitmapData and put up with having the images pixelated when scaled or rotated.

Firstly, Actionscript does have the equivalent of a HashMap.
Everything derived from Object can be treated like so:
var obj:Object=new Object();
obj[someKey]=Hello;
trace(obj[someKey]); // traces Hello
The bracket access on an object actually accesses the properties and
methods of that object.
Hence:
var myClip:MovieClip = ...some movieclip...
trace(myClip._visible);
trace(myClip[_visible]); // equivalent to the last line
myClip.doSomething(1,2,3);
myClip[doSomething](1,2,3); // equivalent to last line.
myClip._y=20;
myClip[_y]=20; // again, equivalent
When you create/attach an instance of a MovieClip to a parent
movieclip, you are actually creating new properties on that parent
clip.
So:
var myClip:MovieClip=someClip.attachMovie(Symbol,aNewClip,1);
trace(myClip==this[aNewClip); // traces 'true'
To get back to your original question, this means you can type:
var myClip:MovieClip=myMovie[anInstanceName_0];
to retrieve your clip.

Re: [Flashcoders] HashMap?
For some AVM1 and AVM2 flash representation of objects, fire up this breeze presentation about the flash player 9. http://seminars.breezecentral.com/p64058844/ Around minute 28 into the presentation, it talks about AVM1 and AVM2 representation of an object. Like I suspected, AVM1 uses a straight hash table. B. 2006/5/16, Ron Wheeler [EMAIL PROTECTED]: Bernard Poulin wrote: If you can not tune a HashMap it will be worse than an ordinary array. It will take more space and more processing time. This will of course depend on the size and usage - it *may* be more efficient with hashmaps. Do you really think we can generalize being it worse all the time? I will not be far wrong. If your primary allocation is to small, many array keys hash to the same spot and you have to search a long linked list. It is is too big, you waste a lot of space. It is not trivial to increase the size of the allocation dynamically since you must rehash all of the entries. Keeping an array ordered to be able to do binary searches can statistically cost a lot of copying at insertion time. You are only adjusting links unless you want a balanced tree. Binary searches may involves a lot more string comparison. In a binary search comparing the string hash value is of no use to know if the value is greater or lower (to decide for the next search direction). In hashmaps, the lookup in the chain after the hash jump can, most of the time, skip a string entry without even looking at the characters by comparing the 32bit integer hashes. String hashes are only useful for looking up a specific value. It is unlikely that the hashes are even stored since once you store the key/value you no longer have any need for the hash since the position in the main table is known and you can follow the links in the overflow back to the main table(usually). If you are hashed into the overflow, you have to examine each key since the hashes are identical for everyone in the list (otherwise they would not be in the list - they would be in another list of collided hashes). About Arrays (this is more than slightly OT) :-) I still believe Arrays are implemented as associative arrays. But this is just pure belief since I have no proof and it could easily change from one version of the VM to the other. Associative array is not a physical description of the implementation. It describes the logical way that an Actionscript programmer finds the value associated with a key. The implementation of Array probably involves a fairly simple linked list of key objects that point to value objects. Whether the keys are linked as a tree structure to speed up access is an interesting question which was raised earlier. var a:Array; a[0] = 'abc'; a[123456789] = 'high index value'; a[this is text] = 'non-integer index'; trace(a.length); /// should output 123456790 Sidenote: I often use this feature of Arrays to make an ordered associative array in one single object. This may look a bit like a hack - but it is perfectly valid. I can both traverse the keys in a fixed custom order and lookup one item with its key directly. Also you can retrieve quickly how many items there are using length. For example, when inserting a new entry, I do something like: a[key] = value; a[a.length] = key; I would really like to have insights into the flash VM implementation so I could do better choices regarding maps and arrays.

Hi Jeff,
Here's a class that will generate an array for N elements that blends
between two RGB values.
Example:
import org.bespoke.color.ColorBlend;
var myBlender:ColorBlend=new ColorBlend(0xFF,0x00FF00);
//to get the RGBN value at 46% between the two...
var resultColor:Number= myBlender.getRGBAt(.46);
//get the blend in an array of 20 steps
var myRGBArray:Array=myBlender.getArrayOfLength(20);
Hope this helps,
Cheers,
t

Re: [Flashcoders] Whats the best tooltip component (actionsciptable)
As an ActionScript programmer, I personally liked this one: http://www.neo-archaic.net/blog/2006/05/09/tooltip.htmSimple and effective: No .mxp, no .fla, no super-complex code to setup, just a single .as file to drop in. Additionally, it seems lots of people are building super-fancy tooltips and somehow simply forgot the basics(!): It must work well and behave as expected. Looking at the source, it sounds like it works with or without the mx components automagically.

Re: [Flashcoders] Whats the best tooltip component
Note: the Firefox issue is a problem in the Demo html page. Not a problem in the tooltip itself of course. About the Width: The width parameter should be named maxwidth. It really does take the size of the text in consideration when computing the width. It simply max it out to the specified size (without being bigger than the whole Stage width). B. 2006/6/9, Marc Hoffman [EMAIL PROTECTED]: Hi Karina, This has some nice features but some problems viewing the demo. In FireFox it doesn't show at all. In I.E. 6 it doesn't show and I get a Flash required message. I was able to view it only by looking at the source and opening the swf directly. It would be nice if the tooltip width were dependent on the text string. That shouldn't be too hard to add, just draw the background after establishing the textfield.text.width.

I believe Outlook uses resources located in mime attachments in the email. I do not think it uses that special data: URI scheme. I did a view source from an email in Outlook and got an image URI like the following: img src='cid:image001.jpg@01C6863F.C5CB6260' It seems that cid: is actually a standard described in RFC 2392.

The original page has since been removed, and the only evidence I can now find of this is at http://www.mustardlab.com/developer/flash/standards/, a page being kept around for archival reasons (see the official fixes section). Though I don't need this technique as an Eolas workaround, I'm still really curious about it. Is it possible to base64 encode a swf file and include that raw data in your web page instead of hosting a separate swf file on your server? Anyone have experience with the Data: URI Scheme? I find it odd that Microsoft would include it in their list of workarounds if their browser didn't support it, but then again, maybe that's why the page was removed. I'd like to at least get this working in Mozilla browsers. Tom, Hey, it's Mustard Lab--that's us. I actually work with Sean Christmann, the author of the page that you referred to, and would refer you to him, but he's out until Monday so I'll take a stab at elaborating on this. The very short answer to your question is that that the data: URI scheme (RFC 2397) is not supported by Internet Explorer. It does, however, work with most other browsers on the market, including Firefox, Opera and Safari. As such, it is not helpful in terms of working around the recent change in IE to bring it into compliance with the Eolas patent. To answer your second question, yes it is possible to use this technique to encode a SWF file within a containing HTML page. A while back, I actually managed to write out a second SWF to a HTML page from another SWF with a bit of Javascript. You can see a working example with source code here: http://dev.psalterego.com/datauri/. Originally, I was experimenting with using the data URI scheme as a possible means to obfuscate SWFs encoded within an outer wrapper SWF to make it slightly more difficult for relatively unskilled script kiddies to quickly recover and decompile the bytecodes for the inner SWF via a simple attack with a decompiler. However, as such a scheme would result in the inner protected SWF being completely inaccessible to Internet Explorer users, I never pursued this idea further. Keep in mind that this technique is not particularly efficient in terms of file size, particularly if the base 64 encoded data is stored in HTML. There are also limitations on the maximum possible length of a URL supported by each browser that effectively limit the size of the data that you can include via a data URI scheme.

Re: [Flashcoders] HashMap?
Ah yes, now that you mention it, I just checked the Java HashMap code and it is not limited to a power of two, here's a snippet: index = (hash 0x7FFF) % table.length; That way, they can still use the same set of 32bit hash values when growing. There is no maximum that can be declared.

Also when rehashing you do not need to really compute new hashes - you just need to re-distribute them based on more bits of the complete hash.

Re: [Flashcoders] HashMap?
I think there are no tuning parameters simply because the language does not (and should not) specify how the Objects are implemented (and not because they are not hashmaps). From what we know so far (i.e. nothing!), this could be anything - like a straight array up to, say, 3 entries and switching to another more complex structure after that. By variable key length did you mean automatically growing the relevant hash size (i.e. involving re-distribution) - A bit like what is happening with the Java HashMap implementation ? B. 2006/5/15, Ron Wheeler [EMAIL PROTECTED]: The tree would make sense. The garbage collection for an associative array is an interesting problem with variable key and value lengths. Ron Scott Hyndman wrote: Well, yes. Now that I think about it my test didn't make much sense, since there would be no way of determining how keys are generated by insertions alone...I was assuming a uniform distribution, and it can't be done without knowing more.

Wouldn't it be true to say that hash maps will get slower as the probability of collisions increase? As the primary area fills up, there will be more occasions when the new key to be added, hashes to a storage location already occupied and a link structure will be needed to store the key(s) in the overflow. Similarly, lookups will start to hit links rather than data which will require that the links into the overflow area be followed. This is where tuning comes in. The fact that there are no tuning options makes it unlikely that hashing is used. Defaults would be hard to set without wasting space or turning the whole thing into a small set of linked lists which work be long to search.

Re: [Flashcoders] Grab IP address
It also depends which IP you want to display. Do you want to display the IP of the client machine or the external IP as seen on the internet? You have to watch out these are not the same as the user might be behind NATs/proxies. For a client-only solution: (wild guess) I think your only chance is to make a socket connection back to your server and look at some of the structures involved in the connection?- The external IP might be available in there (really not sure). I do not know enough about NATs to know if it is even possible(!). The better/safer way is surely a server-based solution. If you want the IP of the client machine - then you will have to look at a flash / javascript / Java solution running on the client machine. One of the core problem is that some connections might not even use TCP/IP and thus there are no IPs involved at all. For example: if you open an html page located on your local hard drive. So any solution you might have on the client side will be some kind of hack one way or the other. I think it can't be standard.

Re: [Flashcoders] HashMap?
If you can not tune a HashMap it will be worse than an ordinary array. It will take more space and more processing time. This will of course depend on the size and usage - it *may* be more efficient with hashmaps. Do you really think we can generalize being it worse all the time? Keeping an array ordered to be able to do binary searches can statistically cost a lot of copying at insertion time. Binary searches may involves a lot more string comparison. In a binary search comparing the string hash value is of no use to know if the value is greater or lower (to decide for the next search direction). In hashmaps, the lookup in the chain after the hash jump can, most of the time, skip a string entry without even looking at the characters by comparing the 32bit integer hashes. About Arrays (this is more than slightly OT) :-) I still believe Arrays are implemented as associative arrays. But this is just pure belief since I have no proof and it could easily change from one version of the VM to the other. var a:Array; a[0] = 'abc'; a[123456789] = 'high index value'; a[this is text] = 'non-integer index'; trace(a.length); /// should output 123456790 Sidenote: I often use this feature of Arrays to make an ordered associative array in one single object. This may look a bit like a hack - but it is perfectly valid. I can both traverse the keys in a fixed custom order and lookup one item with its key directly. Also you can retrieve quickly how many items there are using length. For example, when inserting a new entry, I do something like: a[key] = value; a[a.length] = key; I would really like to have insights into the flash VM implementation so I could do better choices regarding maps and arrays. regards, B.

Re: FW: [Flashcoders] sprouts data structure
oh my apologies, I really did not realize that you had to implement an actual player and thus do all the AI. Actually had no clue about what this game really looked like. I understand it a bit better now: The game plays with 2 players, lines are not straight, new dots can be placed anywhere on the line, one wins when its opponent cannot do a move. Interestingly enough, the outcome is somehow deterministic: from Wikipedia: http://en.wikipedia.org/wiki/Sprouts_(game) []By enumerating all possible moves, one can show that the first player is guaranteed a win in games involving three, four, or five spots. The second player can always win a game started with one, two, or six spots. At Bell Labs http://en.wikipedia.org/wiki/Bell_Labs in 1990http://en.wikipedia.org/wiki/1990, David Applegatehttp://en.wikipedia.org/w/index.php?title=David_Applegateaction=edit, Guy Jacobsonhttp://en.wikipedia.org/w/index.php?title=Guy_Jacobsonaction=edit, and Daniel Sleator http://en.wikipedia.org/wiki/Daniel_Sleator used a lot of computer http://en.wikipedia.org/wiki/Computer power to push the analysis out to eleven spots. They found that the first player has a winning strategy when the number of spots divided by six leaves a remainder of three, four, or five, and conjectured that this pattern continues beyond eleven spots.[] Regards, B. 2006/5/12, Weldon MacDonald [EMAIL PROTECTED]: The reqiurement is that the software be able to play the game, so I need a data structure to store the game position for analysis. The intersection check is moot until I can store the current state of the game, update it, and analyze the potential moves. If moves are made that create a cycle, then the possibility of a vertex, or even a subgraph, being contained by that cycle exists, which removes the possibility of edges to a vertex outside the cycle, but not to the vertexes in the cycle. That would have to be incorperated into the data structure. I think the adjacency list might store the position, but then the AI for the game will be very tough to do. As for the intersection check this will work to prevent an illegal move, but the tougher part will be making the computer move if the best move is a line that loops around other vertices. Or maybe I should forget programming and try my hand at cartooning!

Re: [Flashcoders] HashMap?
I cannot say for AS3 implementation because I never tried it. (Which is the original subject of this topic.) In AS1, AS2 and javascript, I am pretty sure that all objects (including Arrays) are key/value maps. (i.e. Associative arrays) http://en.wikipedia.org/wiki/Associative_array#JavaScript It is very possible that the internal implementation is not a hashmap, but I still think it is a highly efficient map of some sort because this is so central to the language. ...at least this is what I think. I might be completely wrong. B. 2006/5/12, Ron Wheeler [EMAIL PROTECTED]: I would be a little surprised. There does not seem to be any way to control the hash parameters and every array would have a lot of wasted space for nothing and without any way to control the hash size and the percent utilization, you would not get a lot of advantage for the big arrays. The Java HashMap defaults are pretty modest and would yield less than optimal performance with a big array. You can set the parameters if you have a big array and know a bit about the randomness of your keys to get fast lookups with a reasonable trade-off in wasted space Perhaps someone who knows the Flash Player internals could tell for sure.

Re: [Flashcoders] Fitting squares into an area
Aaaah, the Monday-effect: Yes, in fact: the problem with Steve's algorithm is that the squares will almost never entirely fill the area. There will always be empty gaps at every line / column and/or the last line will not be filled completely. If you have 5 squares to fill for example, there will be some space lost somewhere. Unless it exactly fits a 5x1 or 1x5 ratio. Danny: I do not understand your algorithm - could you shed some more (high-level) light on what it is doing? hey! this is actually fun! I love these little algorithms. To compute the square size: I am thinking that we should work with the area ratio somehow. Just to be sure I understand what you want: I am assuming that this is showing a list of things and that it is okay that the last line has less items. If the area is width=305 height=400 and N is 10, it will result in square size is 100 -- the first 2 lines will be almost full (5 pixels gap on each line) and the last line is 1/3 full. Visually: 1 2 3 4 5 6 7 8 9 10 - - Here we are showing a 3x4 rectangle which is the best ratio to fit 10 squares in 305x400. ...is this what you are looking for?

Re: [Flashcoders] Fitting squares into an area
Wow!
I just tried your algorithm with my previous example numbers and it does
output the correct square size (100) - also, internally it has the right
number of columns/lines: e.g. 3x4 (p=3, q=4) As for performance, it took 6
iterations: Since the output was 3x4, the number of iterations was (3 + 4 -
1) = 6. (it started at 1x1 and did 6 iterations: something like: 1x1, 1x2,
2x2, 2x3, 3x3, 3x4)
For N = 100, the number of iteration depends on the ratio: it could be
anywhere from 19 (10x10-1) to 100 iterations (worst case happens if the
output is a single line or a single column). So that would make N
iterations (in worst cases) and ~2*SQRT(N)-1 best case.
I took the liberty of optimizing the method a little bit and renaming a few
internal variables to my personal liking. ;-) -- I did not do any real
life testing on this. But it seems to work on paper.

Danny: I do not understand your algorithm - could you shed some more
(high-level) light on what it is doing?
Sure. The idea is that the optimal size will always be an exact fraction
of
either the width or the height. So what we do is drop down by multiples of
these until we get to the first size that will contain N or more squares.
At
any particular width, we keep track of the two 'next-smallest' widths and
drop down to the largest of these. Run through the algorithm with a few
sample numbers and it should make sense.
It may be that there's a more algebraic approach. The problem is, though,
that there is no simple relationship between floor(x), floor(y) and
floor(xy), which would be needed to come up with any truly useful
solution.
In the end, it turns into quite a complex optimisation problem, and given
that the brute force algorithm is actually pretty fast, it hardly seems
worth the effort :)

Re: [Flashcoders] coordinates of a scaled movieclip
The problem is that even if you change the scaling, you are not changing the
position of the black box in relation of your local movieclip. Your black
box is only moving in relation to the movieclip parent.
What you seem to want are the coordinates in relation to the parent
movieclip.
To get that, you have to convert the coordinates values from your local
movie-clip to its parent. In short: get the bounding rectangle and convert
xMin,xMax, etc. There are methods specifically for that
(localToGlobal/GlobalToLocal). It will do all the dirty computation
(translation, scaling, rotation).
good luck!

Hi,
as far as I know, there is no clean solution to this problem.
However, if you feel hackish, this /could/ work:
var w = myClip._width;
var h = myClip._height;
var clip = myClip.createEmptyMovieClip( foobar,
myClip.getNextHighestDepth() );
with( clip ) {
beginFill( 0x00ff00, 100 ) {
lineTo( w, 0 );
lineTo( w, h );
endFill();
}
var x = myClip._width - w;
var y = myClip._height - h;
clip.removeMovieClip();
Now, (x, y) should be the coordinates of your origin (i.e., top left
is at (-x, -y)).
Maybe. I haven't tested it.
Good luck...

how do I know the coordinates of the topleft corner of an (off-centered)
movieclip, or
the coordinates of the topright corner of a centered movieclip while
scaling
it?
I'm really stuck on this, help would be very much appreciated.
greetings,

Re: [Flashcoders] coordinates of a scaled movieclip
Hey! I may have found a simpler version: MovieClip.getBounds seems to have a parameter for the target space. Example: var bounds = mc.getBounds(_root); ..which, I believe, should convert the bounding rectangle automatically to the _root coordinates. (I think it uses localToGlobal and globalToLocal internally). cheers, B. 2006/4/24, Zeh Fernando [EMAIL PROTECTED]: When I found this out It confused the hell out of me as localToGlobal had never worked like that before - I just assumed I'd never used it with anything scaled by hand before and wrote that off as the reason. Now if what you're saying is true then it gets even more confusing. One difference may be that I'm actually attaching an MC to point MC and trying to get it's coords? I bet when you attach an MC it doesn't inherit the transform matrix info from its parent. Maybe - or maybe because you're loading content from an outside SWF. I've never tested localToGlobal with both attaching and loading; I'd guess it should work, but I can't test it right now to really know. I'll keep it in mind if I have problems with localToGlobal in the future though; thanks for the info, it has made me curious. - Zeh ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] Forcing XML connection closed from SWF
Here's some random ideas: - The keep-alive option is a good thing (everything goes faster) and normally does not impose a problem. If you have a problem on the server because of that (too many threads or too many sockets taken), always remember that it is the responsibility of the server to control this and not the client (browser). - Note that the connection should disconnect by itself after some time. Did you measure how much time you had to wait? (probably a couple of minutes). I think it should never be foreever. Maybe you did not realize this timeout potentially makes this less of a problem. (?) For Internet Explorer, the keepalivetimeout registry setting is KeepAliveTimeout under: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings - If you just want to turn off keep-alive temporarily just to do a test on your machine, it is possible that you can turn it off in your browser's options (set it to not use HTTP 1.1) or by modifying a registry key. Or else, you can try to find a proxy or tcptunnel that could force it off. - A potential brute-force solution (not sure it is really reliable): I know that you can control the keep-alive on a request-basis by modifying the http headers (at least in IE). You can try to use XMLHttpRequest (from javascript) and force to turn off the keep-alive option by setting HTTP Headers. That is - after you finished doing your XML query. -- that's on the client (browser) side - Make many connections to be sure you saturate all the available connections (something like 2, 3 or 4). - Make sure you use a keep-alive-friendly proxy (or tcp tunnel) to really test that the connections are kept alive and that your method really makes a difference. - I do not know if we can control the HTTP Headers from within flash - if you can, try to modify the headers to shutoff the keep-alive option. It *might* be possible with the recent flash player 8 (raw sockets). hope this helps, B. 2006/4/21, Nathanial Thelen [EMAIL PROTECTED]: Thank you for the idea on that one. I am particularly looking for a browser side only solution in this case.

Possibly you could use a php file (or whatever server scripting language you use ) on the server, which does only 2 simple things: 1. Send a HTTP header that indicates not to use keep-alive.

Re: [Flashcoders] SourceSafe??? Recommendations needed.
Few Notes: - CVSNT tries to minimize binary file growth. Do not know how it compares to others. - To compare binary documents, you will probably have to find tools tailored for each file type. For example: for Microsoft Word documents, you can use the built-in Word compare utility. I do not know if anybody tried that, but for SWF files (or even FLAs?) , you could maybe try to convert it to a text file of some sort for the purpose of comparing - there are few tools that can do that (at least for swf files you can use swfmill - not sure for FLA files). Although that technique is not very visual for comparing changes in graphic elements. You can at least know that this graphic named abc changed. Also, for FLA files, we put virtually no code in the files (only a single import statement for the Main class). All the code is stored in external .AS text files - which are easy to compare and update. Bottom line - whatever decision you take: even the worse source-control system will be a far better than nothing. good luck! B. 2006/4/21, [EMAIL PROTECTED] [EMAIL PROTECTED]: Now I will be upfront and state clearly that I don't neccessarily believe that StarTeam has done a lot on the to minimize binary file growth other then to apply compression to the file. What I mean by that is if you were to say take a text file in CVS and look at how it stores it. It does so by saving all the changes into a single text file and uses a markup and indexing system to track what the latest version should be and who made all the individual changes up to that point. Something that can be easily done in text files is not something that can be so easily done with a binary file. As Jester points out, all version control systems to date cannot tell you what changed between saves of an fla or for that matter a swf. ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] Firefox, CSS overflow=scroll, flash buttons bug
I know there is a problem with:
flash + firefox + scrolling regions + mouse coordinates + wmode != window +
Windows Operating System (linux seems fine)
Have you tried using wmode = window? (it might fix your mouse coordinates -
in other words, your buttons may start to work again)
B.
2006/4/21, Mike Guerrero [EMAIL PROTECTED]:
So I am having a weird problem. I have a fullscreen flash displayed in on
html page using flashobject from this example:
http://blog.deconcept.com/flashobject/fullpage.html
I wanted to have scrollbars appear in case it didn't fit the browser
window.
So I changed my css as follow.
/*
html {
height: 100%;
overflow: hidden;
}
To
html {
height: 100%;
overflow: scroll;
}
**/
In IE if you shrink the window, you can scroll the page and click any of
the
flash buttons. In Firefox the buttons do not work. When you try to
rollover
them, the cusor stays as an arrow and the buttons flicker. I believe this
a
bug with firefox. Oh well.

Re: [Flashcoders] New wrinkle in IE activation issue...
Another drawback: (that might be problematic in some cases). This technique has the double run problem. I mean, the flash movie might start running, before the javascript had a change to do its magic of replacing it. Depending on what the flash movie is doing and timing, the result might do a sudden blink. I didn't do extensive testing, but I suspect it might impact the load time of the page since loading a flash movie in IE always seems to hangs the browser for a split second. (depending on the complexity of the flash movie) - so the hanging time would be doubled presumably. I want to point out that this technique is not 100% bad. It is actually one of the best bang-for-the-buck for existing pages. (unlike the FlashObject which requires much more changes). It is great for many cases - it is a brute-force, extremely low-cost method.

Re: [Flashcoders] Re: Active X and Microsoft IE ...
I am sorry, I didn't try your version explicitely but another similar
technique. Probably I jumped on conclusions too fast.
To be precise, what I found is calling innerHTML on an parent object of an
object tag (on IE) does not renders all the attributes correctly. You
could see it by looking at the resulting string in a debugger.
But there are differences that could explain this. The parent object was not
a noscript tag like yours. Also maybe there was a question of timing: I
was calling my external javascript from the end of the page - it was
taking care of all flash objects on the page at once. (unlike your
technique).
I do not recall the exact IE version I was using (probably a very recent
one) and I do not have a quick test bed to try it out again now.
Another drawback I saw is the double initialization of all my flash
movies. Each movie would load and run twice.
hope that helps,
