Convert Image Map Data To Actionscript
I have a website that has a gallery full of hotspotted images. I would like to convert the gallery to Flash. However, I do not wish to "re-hotspot" all the images. Is there a way to convert the hotspot coordinates into Actionscript and receive an equivalent shape and assign actions to it.
<map name="Map">
<area shape="poly" coords="62,104,32,29,97,67,170,32,145,99,166,133,7 7,169,20,163" href="#">
</map>
Any help would be greatly appreciated.

Convert A MC To Image Using Binary Data
How can I change this so it saves the image as binary data. This code works fine but when the image is created the file size is too big.PLEASE HELP!!

Must-read: How To Batch Convert Image Files To Swf (for Image Galleries)
Sorry for cross-posting, but I thought this was important.
If you ever need to create an image gallery in Flash using loadMovie(), read this:
Last night, I was trying to create a Flash image gallery where each of the images are loaded dynamically using loadMovie(). As you know, this is usually a very painful process, since you have to create a movie for each of the image files, adjust the size of the movie, import the picture, set the quality, test, adjust, etc. etc. A conservative estimate of 5 minutes per picture gives us a whopping 2 hours for a gallery of 25 images.
Well, Fireworks 4 allows you to export to swf. Using its javascript API for extending, I was able to create a command where you specify the files to convert, the output dir, and the JPEG quality for bitmaps, and with that info the command batch converts all of the files to swf. The total process takes about 30 seconds!
Here's how you can use it:
Copy everything between these lines (not including the lines) and paste it into an empty NotePad:
Code:
//Batch export to swf; a script for Fireworks 4
//By Patrick Mineault
//patrickmineault@sympatico.ca
function checkForPC(){
if(fw.platform == "win"){
return true;
}
else{
alert("Sorry, this script works only with Fireworks 4 for Windows
" +
"If you would like to help me make the script compatible for the Mac,
" +
"please contact me at patrickmineault@sympatico.ca");
return false;
}
}
function noWindowsOpen(){
if(fw.documents.length == 0){
return true;
}
else{
alert("Please close all documents
before running this script");
return false;
}
}
function getDocs(){
alert("Select the image files
to batch convert to swf");
theDocList = fw.locateDocDialog(50, ["kMoaCfFormat_BMP",
"kMoaCfFormat_GIF",
"kMoaCfFormat_JPEG",
"kMoaCfFormat_PICT",
"kMoaCfFormat_TIFF",
"PNG"
]);
if (theDocList == null || theDocList.length == 0) {
return false;
}else {
return true;
}
}
function getExportPath(){
alert("Please choose an export folder");
thePath = fw.browseForFolderURL();
if (thePath == null || thePath.length == 0) {
return false;
}
else{
return true;
}
}
function getJPEGQuality(){
fw.dismissBatchDialogWhenDone = true;
var notFinished = true;
var result;
while(notFinished){
JPEGQuality = prompt("Non-vector objects will be converted
" +
"to JPEG's during the export process.
" +
"Please enter the JPEG quality.","75");
if(JPEGQuality == null){
notFinished = false;
result = false;
}
else if(!(JPEGQuality >= 0 &&
JPEGQuality <= 100 &&
JPEGQuality == Math.round(JPEGQuality))){
alert("Please enter a valid value");
}
else{
notFinished = false;
result = true;
}
}
return result;
}
function batchProcess(){
fw.batchStatusString = "Exporting as swf... please wait";
fw.progressCountTotal = theDocList.length;
fw.setPref("SwfMaintainObjEditable", true);
fw.setPref("SwfMaintainTextEditable", false);
var numOpenDocs = fw.documents.length;
for (var i = 0; i < theDocList.length; i++) {
fw.progressCountCurrent = i + 1;
var theDoc = theDocList[ i ];
theDocWindow = fw.openDocument(theDoc, false);
fw.setActiveWindow(theDocWindow);
convertToSWF(theDoc);
theDocWindow.close(false);
}
alert("Done!");
}
function convertToSWF(theDoc){
var lastSlash = theDoc.lastIndexOf("/");
//This part won't work on the Mac, since there is no last dot
var lastDot = theDoc.lastIndexOf(".");
var name = theDoc.substring(lastSlash+1,lastDot);
var url = thePath + "/" + name + ".swf";
fw.setPref("SwfJpegQuality", JPEGQuality);
fw.exportSWF(null,url);
}
if(checkForPC()){
if(noWindowsOpen()){
if(getDocs()){
if(getExportPath()){
if(getJPEGQuality()){
batchProcess();
}
}
}
}
}
Save this as "Batch export as swf.jsf" in C:Program FilesMacromediaFireworks 4ConfigurationCommands. The next time you open Fireworks, you'll see a new item in the Command menu, "Batch export as swf". Just run it and follow the instructions.
The script works with gifs, jpegs, bmp, tiff, pict and Fireworks PNG. Note that for Fireworks PNG the paths are exported as vectors, not as bitmaps. I've only tested the script on Windows, it probably won't work for the Mac; luckily there's an if that checks for the platform.
Anyway, enjoy!
Note: If you can fix the incompatibility with the Mac (look at the comment in the convertToSWF() function), please either e-mail me at patrickmineault@sypatico.ca, or post a meesage below.

Convert Xml Data To Number Variable :(
This is really doing my head in?
Could someone please let me know what I am missing.
scenario:
loading xml into flash...all good
retrieve a number from xml...all good
_root.number=my_xml.firstChild.childNodes[0].firstChild
display number we have retrieved...all good
trace(_root.number)//returns 3
add 2 to this number...all goes pear shaped
_root.number+=2
trace(_root.number)//returns "NaN"
I guess I have to convert the parsed xml value somehow but unable to find out how.
Any help greatly appreciated.
Kind thanks

Convert Net.socket Data To String
Hi,
I have a ProgressEvent.SOCKET_DATA listener on my socket object and I am
trying to convert a tutorial to recieve joystick data from a C# project.
I want it to recieve data from a VB6 winsock control. I would prefer
string data here. I though readMultiByte would be the right function but
it doesn't work so well.
Maybe the data send from winsock control istn't the right way or maybe I
am using readMultiByte the wrong way. The application also slows down.
Or shouldn't I use net.Socket because it is more for binary data?
Any ideas?
TIA

Unable To Convert XML String To Number Data Type
Hi all;
I wonder if someone has seen this problem. I am reading a number of text values from an XML file, including one which I would like to identify as the point value (it's a multiple choice game). When I read the childnode value, it is recognized okay in Flash;
ActionScript Code:
pointValue = xmlData.firstChild.firstChild.childNodes[nextCount].childNodes[1].firstChild.nodeValue;
trace window indicates "100" for pointValue (but this is a text string)
When I try to convert the data type to a number;
ActionScript Code:
pointValue:Number = Number(xmlData.firstChild.firstChild.childNodes[nextCount].childNodes[1].firstChild.nodeValue);
This statement (above) gives syntax errors.
If I try something like this;
ActionScript Code:
pointValue = xmlData.firstChild.firstChild.childNodes[nextCount].childNodes[1].firstChild.nodeValue;
pointValue_n = Number(pointValue);
trace window indicates "100" for pointValue
trace window indicates "NaN" for pointValue_n
This seems like it should be an easy step, but I can't figure out why it won't work??
Thanks in advance for any help.

Convert SWF To Image
Hello All,
I'm working on somewhat of a templated system
where I've got a SWF file as a template and then
people upload their own images and place them in
the certain masked areas of the SWF to create
like a scrapbook page.
My question is this, what would be the best way
to convert those images to an image that people
can save and thus print? Would I have to do this
while their viewing the SWF or is there a way to
generate an image with some sort of command line
tool that I'd pass the swf the user's settings to make
the SWF unique each time?
Let me know what'd be best.
Thanks,

Convert Image Format
I need to display images inside a Ruby on Rails project as flash or swf. anyone have any ideas on how this would be done?
I upload images, resize them with mini-magick ( a ruby wrapper for imagemagick) and then place them in the filesystem. I would then like for when they are displayed inside of html to be displayed as swf to prevent people from downloading the files.
Thanks in advance for any ideas.

Convert Actionscript 2.0 To 3.0
Hi,
I've found the following code to generate snowflakes.
however it is from actionscript 2.0.
How can i convert it to actionscript 3.0 ?
i mean that when i test this under actionscript 3.0, flash cs3 tells me
for example 1120: Access of undefined property amount.
and this points to amount = 100.
thanks a lot.
----
amount = 100;
mWidth = Stage.width;
mHeight = Stage.height;
for (var i = 0; i<amount; i++) {
thisFlake = this.attachMovie("flake", "flake"+i, i);
with (thisFlake) {
_x = Math.random()*mWidth;
_y = Math.random()*mHeight;
_xscale = _yscale=_alpha=40+Math.random()*60;
}
thisFlake.yspeed = Math.random()*2+.2;
thisFlake.increment = -0.025+Math.random()*0.05;
thisFlake.radian = 0; //declare for actionscript 2.0
thisFlake.onEnterFrame = function() {
this.radians += this.increment;
//trace(this.radians);
this._x += Math.sin(this.radians);

Convert Canvas To Background Image
Hello, I'm working on a small drawing app.. all is working well for drawing simple shapes. I have a pen tool that simply draws small line segments while the user holds the mouse down and draws. After a while the app really slows down because I have ton's of layers. I really don't need to be moving these shapes around.. so there's a lot of overhead in the layering.
Is there a way to capture all the pixels on the screen, erase all the shapes, then drop down the captured image as a background image. I figure every 100 shapes or so I could do this (if it's a slow process to do).
I found some classes that would probably do it.. but still a bit baffled on how to capture my canvas into an image.
This example I found in the docs seems almost there..
Code:
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.BitmapDataChannel;
var bmd1:BitmapData = new BitmapData(80, 80);
var bmd2:BitmapData = new BitmapData(80, 80);
var seed:int = int(Math.random() * int.MAX_VALUE);
bmd1.noise(seed, 0, 0xFF, BitmapDataChannel.RED, false);
bmd2.noise(seed, 0, 0xFF, BitmapDataChannel.RED, true);
var bm1:Bitmap = new Bitmap(bmd1);
this.addChild(bm1);
var bm2:Bitmap = new Bitmap(bmd2);
this.addChild(bm2);
bm2.x = 90;
Of course this is just putting random noise in the BitmapData, I'd like to capture the current screen and put it in there. Any help would be appreciated
thnx
Daniel

Convert A Javascript To Actionscript
I'm in MX2004, and need to convert a javascript function into an actionscript function. The original function was created by a developer friend who knows nothing of Flash, and I have no idea what he did.
The function is supposed to round a number up to the nearest 1/8 value and it works beautifully - in HTML. There is an input field named rawValue and an output field named calcValue. The function is below, and if anyone could help me with this I would be eternally grateful:
function roundUpTo(fromField,toField,fracValue){
// Get the "source" value field object reference
fromField = (fromField && typeof fromField.value != "undefined") ? fromField : null;
// Get the "target" value field object reference
toField = (toField && typeof toField.value != "undefined") ? toField : null;
// Make sure there is both a "source" and "target" field object reference
if(fromField && toField){
// Get (or evaluate) the "Fraction" parameter passed (if present) -- Default is 1/8
fracValue = (fracValue && (fracValue.match(/[^0-9.*/+-() ]/) == null) && !isNaN(parseFloat(eval(fracValue)))) ? parseFloat(eval(fracValue)) : (1/8);
// Get the original source value (NOTE: parseFloat is executed)
oV = (fromField.value != "" && !isNaN(parseFloat(fromField.value))) ? parseFloat(fromField.value) : 0;
// Get the Integer portion of the supplied original value
cVI = parseInt(oV);
// Get the Decimal portion of the supplied original value
cVF = oV - cVI;
// Round the Decimal portion down to the nearest "fraction" value
cVFD = (parseInt(cVF/(fracValue)) * (fracValue));
// Find the nearest "higher" fractional value
cVFD = ((cVF == cVFD) ? (cVF) : (cVFD + (fracValue)));
// Set the "target" field value to the "rounded up" value (to the nearest "higher" fraction value supplied, or 1/8 if not supplied)
toField.value = cVI + cVFD;
}

Convert Actionscript 2.0 Code To 3.0
I would like to incorporate a very basic paint program into my Flash movie.
I must use AS 3.0.
I followed the tutorial from the URL below, which I think is for AS 2.0.
[url="http://www.pixelhivedesign.com/tutorials/Flash+Painting+Program/"]
It doesn't even work for me using AS 2.0. When I try to play my movie it says "A script in this movie is causing Adobe Flash Player 9 to run slowly. If it continues to run your computer may become unresponsive. Do you want to abort the script?"
The code in the tutorial is:
canvasAbove = attachMovie('canvas_mc','can',2);
canvasAbove._alpha = 50;
painting = createEmptyMovieClip('painting',1);
theBrush = new Object();
theBrush.onMouseDown = function(){
isPainting = true;
painting.moveTo(_xmouse,_ymouse);
painting.lineTo(_xmouse+1,_ymouse+1);
}
theBrush.onMouseMove = function(){
if(isPainting){
painting.lineTo(_xmouse,_ymouse);
}
}
theBrush.onMouseUp = function(){
isPainting = false;
}
Mouse.addListener(theBrush);
painting.onEnterFrame = function(){
ranWidth = Math.round((Math.random() * 10)+2);
painting.lineStyle(ranWidth,0x006600,100);
}
clear_btn.onRelease = function(){
painting.clear();
}
Can anybody help me to convert this code into Actionscript 3.0?
Or do you have an alternative way to make a basic drawing program using AS3.0 and Flash?
Thank you,

Convert Form To ActionScript
I'm working with a flash designer, and we're both trying to convert an html form into actionscript so we can use it in flash, for my new site http://www.AutomaticMoneyMachine.com.
The form needs to call some variables from a line of php, so if it were all php and html, it would look something like this:
<?
session_start();
include("AMMscript.php");
?>
<form method="post"
action="http://www.webbootcamp.com/mail/signup.php">
<input type="hidden" name="list" value="19">
<font face="Sydnie"><font color="#00FF00"><font
size=+2>NAME/font></font></font>
<input type="text" name="fname" value="" maxlength="30"
style="font-family:arial; color:003300; font-size:15pt; background:ffff00;">
<p>
<font face="Sydnie"><font color="#00FF00"><font
size=+2>EMAIL/font></font></font><input type="text" name="email"
maxlength="80" style="font-family:arial; color:003300; font-size:15pt;
background:ffff00;">
<p><input type=submit class="link" value="CONFIRM TRANSACTION"></center>
<input type=hidden name=overwrite_dupes value=1>
<INPUT type="hidden" name="amount">
<INPUT type="hidden" name="user2" value="<? echo $Sponsor; ?>">
<INPUT type="hidden" name="user3" value="<fname>">
<INPUT type="hidden" name="user4" value="<? echo "$Firstname" ?> <? echo
"$Lastname" ?>">
</form>
The actual design elements of the form are not needed (my flash designer has duplicated that portion already). What we need to know, is how to send the hidden fields, and all values, and submit the form.
Also - is there anything special to know about grabbing php session variables into the flash, or can we just put the flash within a php page?
NOTE - the form goes to a mailing list, so it is imperative to somehow define the list number as shown here <input type="hidden" name="list" value="19"> after the form action.
I would be happy to give you free memberships to two separate bu^siness oppo^rtunities I run, http://www.WebBootCamp.com and upcoming http://www.AutomaticMoneyMachine.com to anyone who can help us out with this.

Convert String Into Actionscript Code
I need one function that converts string into actionscript code,
i've been searching but I don't find anything. I'm using Flash 8.
Example:
myString = "Number(var1.txt) * Number(var2.txt) + 1000";
result.text = desiredFunction(myString); // is equal > result.text = Number(var1.txt) * Number(var2.txt) + 1000;
Thanks

Convert String Into Actionscript Code II
Please.. help me with this.
The function above arithmeticParser() by abeall works great BUT,
it doesn't read variables, if I have a variable name "var1" or an instance name "var1.text"
How can I assign to the array the value instead of the variable string?
actionscript layer1:
<code>
/************
/* String arithmetic parsing function - abeall.com
/* takes a string like "1+(5-2)/7((25+3)*2)" and does the arithmetic, respecting parenthesis
/* returns: Number
/************/
function arithmeticParser(str){
if(typeof str!='string')return str;
//clean up
str = str.split(" ").join('').split("Number").join('');
//CORE ALGORITHM///////////////////////////////////
//create nested arithmetic array based on parenthesis
//ex: 1+(5-2)/7((25+3)*2) => ['1','+',['5','-','2'],'/','7',[['25','+','3'],'*','2']]
var arithArr = [];
var currStr = "";
var arrayScope = [arithArr];
for(var i=0 ; i<str.length ; i++){
var char = str.charAt(i);
var currArr = arrayScope[arrayScope.length-1];
if(char=="("){
if(currStr!="")combineArray(currArr,currArr.length ,arithStrToArray(currStr.split("(").join()));
currStr = "";
arrayScope.push(currArr[currArr.length]=new Array());
}else if(char==")"){
combineArray(currArr,currArr.length,arithStrToArra y(currStr.split(")").join()));
currStr = "";
arrayScope.pop();
}else{
currStr = currStr + char;
}
}
combineArray(currArr,currArr.length,arithStrToArra y(currStr));
//dump(arithArr);
str = arrayArithmetic(arithArr);
return str;
//FUNCTIONS////////////////////////////////////////
//splices all elements in the Array 'insertArr' into the Array 'ar' at 'index'
function combineArray(ar,index,insertArr){
for(var i in insertArr){
ar.splice(index,0,insertArr[i]);
}
}
//performs arithmetic() to 3D arrays from deepest array to the top array
function arrayArithmetic(ar){
for(var i in ar){
if(typeof ar[i]=='object'){
ar[i] = arrayArithmetic(ar[i]);
}
}
return arithmetic(ar);
}
//converts arithmetic string to array
//ex: 7+2/8-12 => ['7','+','2','/','8','-','12']
function arithStrToArray(arithStr){
var ar = [];
var currStr = "";
for(var i=0 ; i<arithStr.length ; i++){
var char = arithStr.charAt(i);
if(char=="/" || char=="*" || char=="-" || char=="+"){
if(currStr!="")ar.push(currStr);
ar.push(char);
currStr = "";
}else{
currStr = currStr+String(char);
}
}
if(currStr!="")ar.push(currStr);
return ar;
}
//performs the four basic arithmetic operations to arithmetic formatted array
function arithmetic(ar){
for(var i=0 ; i<ar.length ; i++){
if(ar[i]=="/"){
var n = Number(ar[i-1]) / Number(ar[i+1]); //perform operation
ar.splice(i-1,3,n); //splice out the number,operation,number subarray and replace with the answer number
i=0; //since the array has been modified(spliced) the operation must start over to get all operations
}
}
for(var i=0 ; i<ar.length ; i++){
if(ar[i]=="*"){
var n = Number(ar[i-1]) * Number(ar[i+1]);
ar.splice(i-1,3,n);
i=0;
}
}
for(var i=0 ; i<ar.length ; i++){
if(ar[i]=="-"){
var n = Number(ar[i-1]) - Number(ar[i+1]);
ar.splice(i-1,3,n);
i=0;
}
}
for(var i=0 ; i<ar.length ; i++){
if(ar[i]=="+"){
var n = Number(ar[i-1]) + Number(ar[i+1]);
ar.splice(i-1,3,n);
i=0;
}
}
return ar[0]; //the array should be down to one element: the answer
}
}
</code>
actionscript layer2:
<code>
myString = "(var1 * 2) + 1000";
result.text= arithmeticParser(myString);

Convert FlashVars (html) To Actionscript
How do I convert a FlashVars statement (inside an HTML file) to a statement in actionscript?
Example, suppose I have this snippet of code in an HTML file:
Code:
<embed src="ordering.swf" FlashVars="xmlfile=ordering1.xml&actNum=1"
In English, the above code passes in two parameters "xmlfile" and "actNum" to the loading of ordering.swf.
MY QUESTION: How can I emulate this behavior of FlashVars if I wanted to bypass any HTML file -- using actionscript. How do I pass two parameters into a loading movie?
In other words, I think I need to use the loadmovie command - but how do I pass these two parameters using loadmovie? If I'm not supposed to use loadmovie, then any other suggestions are greatly welcomed!
I have 2 files:
1. Ordering.Swf (as noted in the code above)
2. Parent.Swf (which loads the external ordering.swf passing the two parameters xmlfile and actNum into it)
What is the code for step 2?
Thanks!

How Can I Convert An ActionScript 2 Website To ActionScript3?
I have a website which currently uses Action Script 2.
When I change the Publish settings from Flash 7 to Flash 9 and from ActionScript 2 to ActionScript 3, then publish the file, I get the following warning:
WARNING: Actions on button or MovieClip instances are not supported in ActionScript 3.0. All scripts on object instances will be ignored.
What can I do to correct this error?
Is there a simple tutorial that explains how to make the changes?
I subscribe to Lynda.com but I haven't seen useful there.
I should warn you that I am a beginner when it comes to coding.
Thank you
