I'd like to know a way to measure the real length of a text string in pixels. The problem is that every character has a different width.The length property informs us of how many characters does the string have...but how do we measure the pixels (x space) in a precise way?

View 1 RepliesI am wondering if anyone knows a way to determine the real length in pixels that a phrase uses.The problem lies on the fact that every character does not take the same space (x pixels). Let's say I have a dynamic text field and I want to know how many pixels does the sentence use.is not the same to have:phrase #1 =iiiiiiiiiithanphrase #2 =wwwwwwwwwweven though both are using 10 characters.What is the most precise way to find this out?

If you have an image whose sides are even for example 48 x 24 you may do this and you are just fine:
matrix.translate(-24, -12);
matrix.rotate(Math.PI);
matrix.translate(24, 12);
But if you have an image of size something like 49 x 25, then there is a problem with those odd pixels, how to compute when and where to add or remove those odd pixels so image gets allways perfectly rotated?

View 1 RepliesI am trying to find out what the max length is for a string because since as3 doesnt provide any methods for removing characters from a string by changing the initial string itself, i am going to have to stick to re-initializing.I did a little test to see how long it would take for my program to break using the following code:
Actionscript Code:
+[code]..............
The program crashed at a string length of about 500 million.
EDIT:however before it crashed,it performed the incrementations with reasonable performance.
EDIT EDIT: which is strange since my ram still had over 2 gig the program didnt use
I need to measure some text before I place it down in my scene programmatically. Is there something like a measureString(s:String, f:Font) function? If so, can someone give me some hints of where it is?

Is there an easy way to get the byte length of a string in AS3? String.length works in many cases, but breaks if it encounters mulibyte unicode characters.(in this particular case, I need to know this so I can preface messages sent across a TCP socket with the message length. This is in standard netstring format e.g. "length:message,").
View 1 RepliesI'm populating a dropDownList with arrayCollection of strings. I want the width of the drop down list control to match with the size (in pixels) of the longest string in the array collection. The problem I'm facing is: the font width of the strings in the collection are different e.g. 'W' looks wider than 'l'. So I estimated the width of a character to be 8 pixels but that's not pretty neat. If a string that has many 'W' and 'M' is encountered the estimation is wrong. So I want precise pixel width of strings. How can i get the exact length of a string in pixels??
My solution that estimates all character to be 8 pixels wide is given below:
public function populateDropDownList():void{
var array:Array = new Array("o","two","three four five six seven eight wwww");
var sampleArrayCollection:ArrayCollection = new ArrayCollection(array);

Is there an actionscript function I can use to pad a string to a certain length with a certain character?
Example: I have a number lets say 274 and I want to make sure that number is at least 6 characters long...with any open space receiving the character 'W'. So I'd call the pad function and my final number would look like this: WWW274
I have a string provided to my flash file that I need to break into a max of 3 sentences(strings).
I have written some actionscript to break it up by set lengths, but I also need it to not break words up.
To test you can place the following code in a blank as2 file.
Code:
var personalMessage:String = "You got this far so we reckon that you could be curious enough to learn a little more, we�ll contact you shortly to answer any questions you may have.";
_root.myArray = new Array();
_root.myArray = personalMessage.split("");

I have a string whose length may vary but will always be divisible by 3 and want to push every three characters to an array.
e.g.
var myString = "000111000111";
//magic code converts

just a simple example:
var a = new Array()
a["apple"] = "red"
a["orange"] = "orange"
a["banana"] = "yellow"
trace(a.length) //returns 0
get it work?
I am looking at "length" property in the Adobe AS3.0 language ref as I do not understand it. It says: An integer specifying the number of characters in the specified String object. (I understand this). Because all string indexes are zero-based, the index of the last character for any string x is x. length - 1. (I do not understand the "- 1". I understand that all string indexes are zero-based but I cant put this together with the last character for any string being -1 or whatever it is saying.
View 7 Repliesim just wondering if theres a way to get the real x and y positions of an object in the real movie ( the root screen) that is locted in another movie
i have an object which is within 2 movie clips, first one and then another , and then my object, now i want to know what the real x and y positions of it is, not the locations realtive to the movieclip it is inside.
I'm trying to do a test on the length of a string and then call a function depending on the result. This is the pertinent excerpt from the fla file:
Code:
_loc4._comment = candles[_loc3].comment;
// I want to find out the length of _comment and call differently depending
_loc4.onRollOver = function () {
if (_loc4._comment.length > 0 && _loc4._comment.length < 60) {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 50);
} else {
show_comment(this._comment, this._x + this._parent._x, this._parent._parent._y - 100);
}};
Basically I want to check the length (in characters) of _loc4.comment and if its under 60 call with an offset of 50 and if its not call with an offset of 100.
I am trying to assign a number to a variable that is dynically generated from a binded array...when i try and assign it and trace it out nothing happens, which means I am obviously doing something wrong but I am not sure? just for fun i decided to bind the data to a label like so...

Okay what I after is how to detect the length of the string populated from array...then auto rescale the height of the title_mc as shown in my AS as well as the dynamic created textfield ..so the textfield will display long string + "newline" for long string...(autowrapper)..

i made a function for replacing a text letter by letter. You've probably seen this effect of putting in place of a text a random one, with the length of the new text and then replacing the random text, letter by letter with the new one. It worked fine but I had to do some adjustments, because I needed to vertically align the text to the bottom, and I had the newline character in the text which gave me some issues with the aligning. Since I did this adjustments, string.length returns undefined even if trace(string) shows the correct text in the output window. On the other hand length(string) gives me the right answer. I also use the charAt function which also returns undefined, even if the trace function shows the correct text.
View 7 RepliesI am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

View 2 RepliesLet's say I have array foo and a positive integer y, where foo.length > y.I want to remove elements from foo so that foo.length becomes y (or very close to it).Also, I need to preserve the first and last element of foo. The indices of the removed elements must be spaced apart as equally as possible. Foo can be sliced, or it can be used to create a new array.
Example: if foo = [a,b,c,d,e,f,g,1,2,3,4,5] and y = 6, then trimmedfoo could be [a,c,e,g,2,4,5] or maybe [a,c,e,2,4,5], but not [a,c,e,g,2,4] because the last element of foo is missing.
how to do this
function foo(x:*, ...args):* {
}
function bar(x:*, ...args):* {[code].....
how to expand args ? when I call bar(1,2,3), I wish it call foo(1,2,3), but it call foo(1,[2,3])
