String date = hour () + ":" + day() + "-" + month() + "-" + year();

be careful with this - windows doesn't like : in filenames.

i would also stick with just YYDDMMHH format because that way the files sort more sensibly. java's SimpleDateFormat is probably better than using hour() etc because hour() doesn't pad single digit hours and that will also cause confusion. (you can use nf() though)

Cool. Fixed my formatting. I've got an incrementing number to keep the files unique (I think?). Now I'm having trouble incorporating, @GoToLoop, your suggestion. The code looks really simple, but I can't get it to work. I added this to my setup:

  final String PATTERN = "H:mm:ss:SSS";
  final SimpleDateFormat formatter = new SimpleDateFormat(PATTERN);
  Date now = new Date();
  String formatted_date = formatter.format(now);

And then have this for my save in the for loop:

  sourceImage.save("/Users/Petros/Desktop/Chips/IndividualChips/NumberingTest/"+"Chip_"+file_number+"_"+formatted_date.png"); 
  file_number+=1;

But I'm getting the error "String literal is not properly closed by a double quote." Why should file_number not need a double quote but formatted_date does? Or, any suggestions on how to properly put the formatted date into the filename? I'm really thankful for all the help you folks have provided!

Thanks @koogs. Is simpleDateFormat included in processing already or do I have to add a library? I found this and this but my code isn't working for it. I put this in the setup section

int dateFormat;
  dateFormat = SimpleDateFormat("yyyy-MM-dd HH-mm-ss") ;

But the console (right term?) says "The function "SimpleDateFormat(String) does not exist". I'm probably doing something obviously wrong. Any pointers on how to do this right? I've read this and this.

Definitely get your point about the saveFrame() and #####; that was kind of a shot in the dark. When you say "Add X and y to the filename to save all of them" I'm not sure what you mean. Can you elaborate for me?

The ###### in the filename gets replaced with the frame number. But this is the same for all values of your for loop as they are all drawn in the same frame. So each is overridden by the next meaning you only see the last.

Add X and y to the filename to save all of them.

And look at Java's simpleDateFormat...

I have modified a lot of code, added them up and came up with this..Here the sound representing points are presented in horizontal ..I want these points to be put vertical..But with this code I cant get my logic right..Any help?TIA..

Hello guys! Need some help!

I am trying to use save frame to take a screenshot of a plot I have currently programmed with processing. The plot GUI has several Buttons (made with Cp5) and Toggles. I have set a function which is being called when a button is pressed. However, sometime the frame I take comes with the cp5 buttons GUI but sometimes doesn't. So some frames have the buttons but some don't. For example:

Hope, you can see the frames. The code I use for the button is:

Button b1 = cp5.addButton("takeScreenShot").setPosition(z, w).setSize(100, 80);

  b1.addCallback(new CallbackListener() {
    public void controlEvent(CallbackEvent theEvent) {
      switch(theEvent.getAction()) { 
        case(ControlP5.ACTION_PRESSED): 
        if (flag) {
          println("Taking photo...");
          takeScreenShot();
        }
        break;
         case(ControlP5.ACTION_RELEASED): 
         println("Done");
         flag = true;
         break;
      }
    }
  }
  );

and the function called for the takeFrame():

void takeScreenShot() {
      String photoDate = new SimpleDateFormat("yyyy_MM_dd-HH_mm_ss").format(new Date());
      String Date = new SimpleDateFormat("yyyy_MM_dd").format(new Date());
      int m = millis()/1000; //for seconds
      saveFrame("C:/Users/. . . .. . ./data/"+ Date + "/photos/" +  "/manual/"+ photoDate + String.valueOf(m)+ ".jpg");
    }

Is there any suggestions on how to tackle this problem?? I would appreciate any help, and any clarifications if needed.

ps. If the photos don't show, the buttons from cp5 configurations sometimes show sometimes don't. Can't find any reason why.!

Hi, I found some code in the old forum which I'm trying to modify to pull in image URL from a webpage. In the original code it is matching an image tag in the form of

<IMG SRC="image/1207/AR1520_071112friedman900.jpg"

Using

// Optional spaces, the IMG tag and its attribute, capture of the URL, anything after it
Pattern pat = Pattern.compile("\\s*<IMG SRC=\"(image/.*?)\".*");

However I want to match/extract a tag in the form of

<a class="link" href="GOPR0237.JPG">GOPR0237.JPG</a>

(where the 4 digits between "GOPR" and ".JPG" are unknown, ultimately it will be compiled into the url

"http://10.5.5.9:8080/DCIM/100GOPRO/GOPRxxxx.JPG" so the image can be downloaded.

This is the current full code if anyone's interested

import processing.net.*;
import java.util.regex.*;
import java.util.*;
import java.text.*;

Client c;
String URL_BASE = "http://10.5.5.9:8080/DCIM/100GOPRO/";  // Where the Gopro stores it's images

PImage GoProImage;

Pattern pat = Pattern.compile("\\s*href=\"(GOPR.*?)\".*"); //NOT CURRENTLY WORKING!

void setup()
{

  size(4000, 3000); 
  background(50);
  fill(200);

  DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
  String imageName = "GoPro-" + df.format(new Date()) + ".jpg";

  c=new Client(this, "10.5.5.9", 80);
  c.write("GET /bacpac/SH?t=oakh6214&p=%01 HTTP/1.0\r\n");
  c.write("\r\n");

  String url = findImageURL(URL_BASE);
  print(url);
  if (url != null) // Found
  {
    GoProImage = loadCachedImage(imageName, URL_BASE + url);
  }
}

void draw()
{
  image(GoProImage, 0, 0);
}

String findImageURL(String pageURL)
{
  String url = null;
  String[] lines = loadStrings(pageURL);
  for (String line : lines)
  {
    Matcher m = pat.matcher(line);
    if (m.matches())
    {
      url = m.group(1);
      break;
    }
  }

  return url;
}

PImage loadCachedImage(String fileName, String url)
{
  PImage img = loadImage(fileName);
  if (img == null) // Not downloaded yet
  {
    img = loadImage(url);
    if (img != null)
    {
      img.save(fileName); // Cache of the file
    } else
    {
      println("Unable to load the image from " + url);
      exit();
    }
  }
  return img;
}

I changed your receive function to this other way shown below. Not sure if the negative offsets artificially introduced are due to working with int data types. It will be great to have a better way to do the conversion. Can you comment about that negative value?

Kf

import java.nio.ByteBuffer;
import java.util.Date;
import java.text.SimpleDateFormat;


void receive( byte[] data )  // <-- default handler
{   
  // NOTICE ByteBuffer.wrap(data, 40, 4).getInt() is same value as your variable "af" in your code
  ByteBuffer bb =ByteBuffer.wrap(data, 40, 4);
  //2*1104494400   is the offset to get correct time
  //Factor of 1000 to convert seconds to msecs
  Date date = new Date( (long)(ByteBuffer.wrap(data, 40, 4).getInt()-2*1104494400)* 1000);
  SimpleDateFormat sdf = new SimpleDateFormat("EEEE,MMMM d,yyyy h:mm,a");
  System.out.println(sdf.format(date));

}

Hi,

I've written the following code to convert a CSV file into JSON and it all works fast and efficiently. The only issue I have is that it produces an 'unminified' JSON format rather than my preferred format of 'minified'. Is there a simple change I could make to the program or an option I could use to produce a minified format?

Many thanks!

Table csv  = loadTable("D:/09SEP16.csv", "header");
JSONArray values = new JSONArray();
int i=0;
String isoDate; 

for (TableRow r : csv.rows ()) {
      JSONObject json = new JSONObject();
      try{ 
       isoDate = new SimpleDateFormat("yyyy-MM-dd").format(new SimpleDateFormat("ddMMMyy").parse(r.getString("DATE")));
      } 
      catch (Exception e){
        println("Date Error");
        isoDate = "01-01-2017";
      }

      json.setString("T", r.getString("TIME"));
      json.setInt("S", r.getInt("S"));
      json.setString("U", r.getString("USER"));
      json.setString("F", r.getString("FULLPATH"));
      json.setString("i", isoDate);
      values.setJSONObject(i++, json);
    }

    saveJSONArray(values, "D:/09SEP16.json");
    println(csv.getRowCount());
    exit();

Look at java's SimpleDateFormat

do you have multiple beginRecord()s as well as multiple endRecord()s? i think you need to.

just change the filename in the beginRecord(). use a counter, or frameCount, or simpleDateFormat to generate a unique filename.

SimpleDateFormat is a Java Class; so the nearest equivalent for use with p5js is JavaScript's built-in Date object...

...though as koogs says; depending on your needs a substring might be simpler.

Is SimpleDateFormat compatible with P5.JS? I need to convert "YYYY-MM-DD HH:mm:ss" to just a simple "HH". I can't seam to find any instruction on how to set it up. Thanks.

Java's simpleDateFormat was made for this.
