Most of the code below is from a ImageJ template, with only the last 6 lines being custom-made. The purpose is to choose only certain frames in a video, and export the smaller video as .avi. I wish to batch-process this. However, the last piece of code (that saves the video) doesn't seem to work... any ideas?
input = getDirectory("Input directory");
output = getDirectory("Output directory");
Dialog.create("File type");
Dialog.addString("File suffix: ", ".avi", 5);
Dialog.show();
suffix = Dialog.getString();
processFolder(input);
function processFolder(input) {
list = getFileList(input);
for (i = 0; i < list.length; i++) {
if(File.isDirectory(input + list[i]))
processFolder("" + input + list[i]);
if(endsWith(list[i], suffix))
processFile(input, output, list[i]);
}
}
function processFile(input, output, file) {
open(input + file);
run("Make Substack...", " slices=1-293-5");
run("AVI... ", "compression=None frame=1.96 save=&output+&file");
close();
close();
}
run("AVI... ", "compression=None frame=1.96 save=&output+&file");
You should use proper string concatenation here:
run("AVI... ", "compression=None frame=1.96 save=" + output + file);

I have used following code for file reading and writing.
private void StorePuzzleData ()
{
FileInfo fileInfo = new FileInfo (Application.persistentDataPath + "\\" + difficultyLevel + puzzleId + ".txt");
if (fileInfo.Exists)
fileInfo.Delete ();
string fileData = string.Empty;
foreach (CellInformation cellInfo in cellInfoList)
fileData += cellInfo.RowIndex + "#" + cellInfo.ColIndex + "#" + cellInfo.number + "#" + cellInfo.CellColor + "#" + cellInfo.CellDisplayColor + "#" + (cellInfo.IsGroupComplete ? 1 : 0) + ",";
StreamWriter streamWriter = fileInfo.CreateText ();
streamWriter.WriteLine (fileData);
streamWriter.Close ();
DataStorage.StorePuzzleTimePassed (difficultyLevel, puzzleId, GameController.gamePlayTime);
}
private void ReadPuzzleData ()
{
// format: rownumber, colnumber, number, cellcolor, celldisplaycolor, isgroupcomplete
StreamReader streamReader = File.OpenText (Application.persistentDataPath + "\\" + difficultyLevel + puzzleId + ".txt");
string fileData = streamReader.ReadLine ();
}
But I am getting following error in actual iOS device running. This code working correct in iMac as well in android device.
Please give me some suggestion what changes I need to do to make this correct.
It seems you're using Windows-style paths in a Unix-like (Apple Mac OS) environment. Notice that on windows you have paths with a backslash like
C:\Users\Maxi\Desktop
On Unix-like system however something like
/var/mobile/Containers
You notice that in your faulty path you have mixed forward and backward slashes, which makes the path invalid.
/var/mobile/Containers/Data/Application/2.....\debutan1.txt
The correct way to always generate the correct path is to use the Path.Combine(string, string) function. This will combine two paths using the correct directory path seperator, which can also be seperatly accessed through Path.DirectorySeparatorChar.
So, in order to make your code correct, you would do
using System.IO; /* must be imported */
private void StorePuzzleData ()
{
FileInfo fileInfo = new FileInfo (Path.Combine(Application.persistentDataPath, difficultyLevel + puzzleId + ".txt"));
if (fileInfo.Exists)
fileInfo.Delete ();
string fileData = string.Empty;
foreach (CellInformation cellInfo in cellInfoList)
fileData += cellInfo.RowIndex + "#" + cellInfo.ColIndex + "#" + cellInfo.number + "#" + cellInfo.CellColor + "#" + cellInfo.CellDisplayColor + "#" + (cellInfo.IsGroupComplete ? 1 : 0) + ",";
StreamWriter streamWriter = fileInfo.CreateText ();
streamWriter.WriteLine (fileData);
streamWriter.Close ();
DataStorage.StorePuzzleTimePassed (difficultyLevel, puzzleId, GameController.gamePlayTime);
}
private void ReadPuzzleData ()
{
// format: rownumber, colnumber, number, cellcolor, celldisplaycolor, isgroupcomplete
StreamReader streamReader = File.OpenText (Path.Combine(Application.persistentDataPath, difficultyLevel + puzzleId + ".txt"));
string fileData = streamReader.ReadLine ();
}
If this still gives an "Access denied" error it must be because of filepermissions. Post the output of ls -la <thatpath> then.
I'm creating the below which is doing fine except for one problem:
function showDevices() {
for (var i = 0; i < devices.length; i++) {
var value = devices[i].Value;
var geraete_id = devices[i].Key;
if (value.Name != "") { // if name exists, use that as heading, else, use UDID
$("#geraete-list").append("<li id='geraete-"+i+"'><a href='#'><h5>" + value.Name + "</h5>"
+ "<p>" + value.LastUsedBy + "</p>"
+ "<p id='geraete_DID'>" + geraete_id + "</p>"
+ "<p>Zuletzt Verwendet: " + formatDate(jsonToDate(value.LastUsed)) + "</p></a>"
+ "<a href='#confirm_device_removal' class='deleteListItem' data-rel='dialog'></a></li>");
}
else {
$("#geraete-list").append("<li id='geraete-"+i+"'><a href='#'><h5 id='geraete_DID'>" + geraete_id + "</h5>"
+ "<p>" + value.LastUsedBy + "</p>"
+ "<p>Anonymous User</p>"
+ "<p>Zuletzt Verwendet: " + formatDate(jsonToDate(value.LastUsed)) + "</p></a>"
+ "<a href='#confirm_device_removal' class='deleteListItem' data-rel='dialog'></a></li>");
}
}
$("#geraete-list").listview("refresh");
}
The problem is that class='deleteListItem'gets turned into class='deleteListItem ui-btn ui-btn-icon-notext ui-icon-delete'
Is this just the way Chrome is reading it or is jQuery Mobile adding this into my class?
The problem is I want to run the below code but the getDeviceIDforRemoval() isn't doing anything...
function getDeviceIDforRemoval(){
$(".device_to_remove").text($("#geraete_DID").text()); // sends the device ID into confirm submission dialog
}
function removeDevices(){
var geraetID = $(this).find('span').text(); //retrieves the DID inserted by above function
removeDevice(geraetID,loadDevices);
}
function removeDevice(udid,onSuccess){
Server.removeDevice(udid,onSuccess);
}
Elements can have multiple classes and when these are shown in the HTML they appear as
class="class1 class2 class3"
Order is largely unimportant.
This code...
$(".device_to_remove").text($("#geraete_DID").text());
...will select all elements with class device_to_remove regardless of whether other classes are also applied to those elements. It will then attempt to set the text of those elements to the text of the element with id geraete_DID.
Which of your elements actually has the class device_to_remove? I see no other reference to this in your code?
new to actionscript and looking at the GeolocationEvent.UPDATE examples, having some unexpected results with .appendText() and an array.push --I didn't know whether they might both be just the phone not keeping up with the updates?
first, the text problem is that it's overwriting rather than replacing the last write, so after a couple minutes of the app running on the phone, you can't read the numbers any more. --using this.removeChild() and then addChild() was about trying to get it to remove the last write before writing again.
and then second, the problem with the array is that it's outputting random .length numbers in the trace() --the length looks to occasionally reset to 2 before counting up again, and counts up to seemingly random numbers. I know that I don't want the overhead of an array in the final version, but I'm trying to learn from why it's not working.
I've commented out the different things I've tried --sorry if I've missed something basic here
var format:TextFormat = new TextFormat();
format.color = 0xff0066;
format.font = "Lucida Console";
format.size = 20;
var fl_GeolocationDisplay:TextField = new TextField();
fl_GeolocationDisplay.defaultTextFormat = format;
fl_GeolocationDisplay.x = 10;
fl_GeolocationDisplay.y = 20;
fl_GeolocationDisplay.selectable = false;
fl_GeolocationDisplay.autoSize = TextFieldAutoSize.LEFT;
//fl_GeolocationDisplay.text = "Geolocation is not responding. Verify the device's location settings.";
fl_GeolocationDisplay.text = " ";
addChild(fl_GeolocationDisplay);
var gpsArray:Array = [42.09646417];
if(!Geolocation.isSupported)
{
fl_GeolocationDisplay.text = "Geolocation is not supported on this device.";
}
else
{
var fl_Geolocation:Geolocation = new Geolocation();
fl_Geolocation.setRequestedUpdateInterval(60000); //android overrides setRequestedUpdateInterval()
fl_Geolocation.addEventListener(GeolocationEvent.UPDATE, fl_UpdateGeolocation);
fl_Geolocation.addEventListener(StatusEvent.STATUS, gpsStatusHandler);
}
function fl_UpdateGeolocation(event:GeolocationEvent):void
{
//gpsArray.push(event.latitude);
//gpsArray[gpsArray.length] = event.latitude;
gpsArray.unshift(event.latitude);
var speed:Number = event.speed * 2.23693629;
if (gpsArray[gpsArray.length - 2] != gpsArray[gpsArray.length - 1])
{
trace(gpsArray.length + "|" + gpsArray[gpsArray.length - 2] + "|" + gpsArray[gpsArray.length - 1]);
trace(gpsArray[1] + "|" + gpsArray[0]);
trace(gpsArray[gpsArray.length - 2] - gpsArray[gpsArray.length - 1]);
}
//this.removeChild(fl_GeolocationDisplay);
fl_GeolocationDisplay.parent.removeChild(fl_GeolocationDisplay);
//fl_GeolocationDisplay = null; //TypeError: Error #2007: Parameter child must be non-null.
addChild(fl_GeolocationDisplay);

//fl_GeolocationDisplay.text = (event.latitude.toString() + "\n");
//fl_GeolocationDisplay.appendText(event.latitude.toString() + "\n");
//fl_GeolocationDisplay.appendText(event.longitude.toString() + "\n");

}

I really can't understand what it is that you are trying to do, I mean you say one thing but your code seem to say something different.
There is also a serious issue about where the different code snippets are located? It Seems like the top part is inside a constructor. And then the bottom part are their own functions? If that is the case, make sure that the constructor is not run multiple times (which seems to be the issue and explaining why items are "overwritten" on top of each other.
Also your question states something about appendText but it seems like you want to replace the text inside the textfield? AppendText will add extra text inside that text field.
Anyways, I did an implementation from your code that gets the "longitude|lattitude" from the update event and then appends these to the textfield on a new line. Maybe this is what you wanted to do? I commented out the gps-array since I had no idea what it was that you tried to achieve by doing this:
package {
import flash.events.GeolocationEvent;
import flash.events.StatusEvent;
import flash.sensors.Geolocation;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
import flash.text.TextFormat;
public class Foobar extends MovieClip {
var gpsArray:Array = [42.09646417];
var format:TextFormat = new TextFormat();
var fl_GeolocationDisplay:TextField = new TextField();
var fl_Geolocation:Geolocation = new Geolocation();
public function Foobar() {
format.color = 0xff0066;
format.font = "Lucida Console";
format.size = 20;
fl_GeolocationDisplay.defaultTextFormat = format;
fl_GeolocationDisplay.x = 10;
fl_GeolocationDisplay.y = 20;
fl_GeolocationDisplay.selectable = false;
fl_GeolocationDisplay.autoSize = TextFieldAutoSize.LEFT;
//fl_GeolocationDisplay.text = "Geolocation is not responding. Verify the device's location settings.";
fl_GeolocationDisplay.text = " ";
addChild(fl_GeolocationDisplay);
if(!Geolocation.isSupported) {
trace("unsupported");
fl_GeolocationDisplay.text = "Geolocation is not supported on this device.";
} else {
trace("supported");
fl_Geolocation.setRequestedUpdateInterval(500); //android overrides setRequestedUpdateInterval()
fl_Geolocation.addEventListener(GeolocationEvent.UPDATE, fl_UpdateGeolocation);
fl_Geolocation.addEventListener(StatusEvent.STATUS, gpsStatusHandler);
}
}
function fl_UpdateGeolocation(event:GeolocationEvent):void {
/*gpsArray.unshift(event.latitude);
var speed:Number = event.speed * 2.23693629;
if (gpsArray[gpsArray.length - 2] != gpsArray[gpsArray.length - 1]) {
trace(gpsArray.length + "|" + gpsArray[gpsArray.length - 2] + "|" + gpsArray[gpsArray.length - 1]);
trace(gpsArray[1] + "|" + gpsArray[0]);
trace(gpsArray[gpsArray.length - 2] - gpsArray[gpsArray.length - 1]);
}*/
fl_GeolocationDisplay.appendText(event.latitude.toString() + "|" + event.longitude.toString() + "\n");
}

I have data read from 2d bar code pdf417. It contains an embedded image in the format of (jfif), The image is not at the beginning of the decoded data it has some data fields and the image is somewhere after, the data fields does not seam to have fixed lengths. How can I extract the Image from the decoded data. I used ClearImage Library to decode the barcode and I have it as text and Hex.
Please help. Thank you in advance
I was able to extract the image thanks to many experts in StackOverflow, I have being reviewing their posts. The following code explains how to extract the image from a mixed binary file, the code is not so beautiful but it can do the job. It searches for (JFIF) image header and extracts it into an image file.
public static void ExtractImage(string fname)
{
try
{
FileStream fs = new FileStream(fname, FileMode.Open);
BinaryReader br = new BinaryReader(fs);
//read the first binary
char[] soi="Empty".ToCharArray();
br.BaseStream.Position = 0;
long imgpos = 0;
ushort r = 0;
while ((r = br.ReadUInt16())> 0)
{
Console.WriteLine(r);
if (r == 0xd8ff)
{
Console.WriteLine("Detcted----->");
imgpos = br.BaseStream.Position;
break;
//UInt16 jfif = br.ReadUInt16(); // JFIF marker
//Console.WriteLine("jfif " + jfif);
//if (jfif == 0xe0ff || jfif == 57855)
// Console.WriteLine(" also Detected--->");
}
}
//now copy to stream
FileStream str = new FileStream("bcimage.jpg", FileMode.OpenOrCreate, FileAccess.Write);
BinaryWriter bw = new BinaryWriter(str);
br.BaseStream.Position = imgpos-2;
int l = (int)(fs.Length - imgpos - 2);
bw.Write(br.ReadBytes(l));
fs.Close();
br.Close();
}
catch (Exception exp)
{
MessageBox.Show(exp.Message);
}

I want to display a twitter feed of a user on my website. What is the simplest way to do this? I guess Javascript. What I want specifically is for the last 5 tweets to load & then, when another tweet is made, for that to automatically appear at the top of the Tweets. It needs to cover pretty much the whole website, apart from the header & footer. Any suggestions/code to do that?
Cheers, help greatly appreciated!
Loading new data without refreshing will need to be AJAX. To get the data, ses the Twitter API http://apiwiki.twitter.com/. The API will allow you to get the data in the format of choice (xml, json, ect...) which you can then parse and return either the data or HTML to the page that submitted the AJAX call. That should give you a push in the right direction.
Simplest way would be adding the Twitter widget : http://twitter.com/goodies/widget_profile and it updates new tweets automatically (using AJAX I think). You ca set the dimensions too.
use any twitter wrapper calss for example this http://emmense.com/php-twitter/ to get the status and display it. than use javascript time function inside function make ajax call to php script and append latest tweet on top of your container.
you can use jquery for dom update
$('#dividhere').prepend('Bla bla bla');
use jQuery, sry for my programming language, but i like our czech lang
<script type="text/javascript">
jQuery(document).ready(function($){
$.getJSON('http://api.twitter.com/1/statuses/user_timeline/##USERNAME##.json?count=2&callback=?', function(zpravicky){
$("#twitter").html(formatujExtSocialniProfil(zpravicky));
});
});
</script>
in external javascript file code like this
function formatujExtSocialniProfil(twitters) {
var statusHTML = [];
for (var i=0; i<twitters.length; i++){
var username = twitters[i].user.screen_name;
var status = twitters[i].text.replace(/((https?|s?ftp|ssh)\:\/\/[^"\s\<\>]*[^.,;'">\:\s\<\>\)\]\!])/g, function(url) {
return ''+url+'';
}).replace(/\B#([_a-z0-9]+)/ig, function(reply) {
return reply.charAt(0)+''+reply.substring(1)+'';
});
statusHTML.push('<li><span>'+status+'</span> <br/><b>'+relative_time(twitters[i].created_at)+'</b></li>');
}
return statusHTML.join('');
}
function relative_time(time_value) {
var values = time_value.split(" ");
time_value = values[1] + " " + values[2] + ", " + values[5] + " " + values[3];
var parsed_date = Date.parse(time_value);
var relative_to = (arguments.length > 1) ? arguments[1] : new Date();
var delta = parseInt((relative_to.getTime() - parsed_date) / 1000);
delta = delta + (relative_to.getTimezoneOffset() * 60);
if (delta < 60) {
return 'seconds ago';
} else if(delta < 120) {
return 'minute ago';
} else if(delta < (60*60)) {
return (parseInt(delta / 60)).toString() + ' minutes';
} else if(delta < (120*60)) {
return 'hours ago';
} else if(delta < (24*60*60)) {
return 'ago ' + (parseInt(delta / 3600)).toString() + ' hours';
} else if(delta < (48*60*60)) {
return 'yesterday';
} else {
return 'since ago' + (parseInt(delta / 86400)).toString() + ' days';
}
}
