How do I write JPG or GIF files

Hi,
Is there anyway I can write the Image object into GIF or JPG file appropriately?
Thanks!
Regards,
Thomas.

I replied to a similar question in the Java programming forum. Here is the URL:

Here are steps to convert Image to BufferedImage,
1. Construct a BufferedImage object
2. Get the graphics context
3. Draw the Image object over this graphics context.
   public static BufferedImage convertToBufferedImage(Image img,
                                     int wid, int ht, int type){
       BufferedImage bi = new BufferedImage(wid, ht, type);
       Graphics2D g2d = bi.createGraphics();
       g2d.drawImage(img, 0,0,wid, ht, null);
       return bi;
   }The type parameter represents the type of the BufferedImage (such as TYPE_INT_RGB). See the Javadocs for the BufferedImage class.
To write to a GIF file, you may have to use a commercial package.

How to deal with addition of .jpg or .gif file

how do i add a LARGE .jpg or .gif image to a JPanel? and is it possible to add JTextField or other features onto the .jpg or .gif file after the addition of the image?
Thanks for the time and consideration.

If you want the image to just be the background for a panel then you will need to subclass JPanel and override the paintComponent(Graphics) method. In the paintComponent(Graphics) method you will need to draw the image yourself using the Graphics.drawImage() method. For loading the image I would suggest using one of the ImageIO.read() methods.

How can I write relative path in File, ImageIcon objects

I have downloaded examples from
http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/index.html
but for some reason images are invisible until I write absolute paths?(I use windows) How can I write relative path in File, ImageIcon objects?

Hello;
I've found a lot of complaints about this through the Forte forum as well as on Dejanews. I'm just curious as to whether any of you ended up finding a solution to this problem.
There was one posting about setting up the subdirectory as a URL rather than a String and then using that as the source of the ImageIcon ... but this didn't work for me.
Any help whatsoever would be appreciated.
Thanks!

Jpg and gif files not showing up on recipient's email

When I attach photos on an email sent from whichever email address through my Mail Application (the one that comes with all Mac OS), sometimes people using AOL or other mail servers don't even see the files. Usually, I think all the problems are with jpg, pdf, and gif files and not .doc files or any text files. they seem to see the text files without any problems. So then Im forced to go to my gmail through safari and attach one by one. Honestly, I find the click and drag en masse of the files I want as attachments much easier, but I want to know how and what is the reason that some servers continuously cannot see my files. Sometimes they see the files as I attach them, meaning as photos on the actual email. And they get confused and don't know how to download them because they say that on the email application they use (gmail for example) there is nowhere where it says download attachments. What is going on and what can I do on my mail application to change this. its really frustrating because my work makes me email lots of photos and sometimes this problem is extremely cumbersome and annoying

Some email readers have trouble with enclosures (particularly graphics) from within an email that is formatted as Rich Text. If you format your mail as Plain Text (see the Format menu) then I expect they will see the enclosures.

How to give write permissions to any file in mac os x 10.8.3

How can we give write access to the file in mac os x 10.8.3.It is not allowing to login as root user also.Can any one please help me in this.I think in mac os x 10.8.3 security update only bloocked this root access.We can give permissions to anyfile upto mac os x 10.8.2.How can we edit any system files?

Download TextWrangler from BareBones' website, not the Mac App Store. It will allow you to edit system files by authenticating. The Mac App store version doesn't have that capability.
You could also edit them in the Terminal with pico, nano, emacs (perhaps more). TextWrangler is much easier to use, though.

How to have my Jpg and RAW files in version sets (PSE10)

I take both jpg and RAW files on my camera so that most of the time I am pleased with the jpg and do little editing, but some of the time I need to really work on a photo which is where the RAW file comes in handy. In my photo well I have 2 of each picture displayed ie the jpg and RAW. How can I get it so only the jpg is displayed and the RAW either hidden or as a version set collapsed? Having 2 of each photo makes the photo well look untidy and full of duplicates.
Help appreciated.

Highlight the two photos (using Ctrl+click), right-click on one of them and select "Stack...Stack Selected Photos".

end;can any please help me how can I overcome this problem
Thanks,

You can write by breaking it into small chunks. Also you can try to use DBMS_XSLPROCESSOR.CLOB2FILE. For UTL_FILE the code snippets may looks like
-- Read chunks of the CLOB and write them to the file
-- until complete.
   WHILE l_pos < l_blob_len
   LOOP
      DBMS_LOB.READ (rec.l_clob, l_amount, l_pos, l_buffer);
      UTL_FILE.put_line (l_file, l_buffer, FALSE);
      l_pos := l_pos + l_amount;
   END LOOP;

How can i write also to xml file the settings of the Tag property to identify if it's "file" or "directory" ?

The first thing i'm doing is to get from my ftp server all the ftp content information and i tag it so i can identify later if it's a file or a directory:
private int total_dirs;
private int searched_until_now_dirs;
private int max_percentage;
private TreeNode directories_real_time;
private string SummaryText;
private TreeNode CreateDirectoryNode(string path, string name , int recursive_levl )
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);
var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);
total_dirs += directories.Count<FTPListDetail>();
searched_until_now_dirs++;
int percentage = 0;
foreach (var dir in directories)
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name, recursive_levl+1));
if (recursive_levl == 1)
TreeNode temp_tn = (TreeNode)directoryNode.Clone();
this.BeginInvoke(new MethodInvoker( delegate
UpdateList(temp_tn);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
foreach (var file in files)
TreeNode file_tree_node = new TreeNode(file.Name);
file_tree_node.Tag = "file";
directoryNode.Nodes.Add(file_tree_node);
numberOfFiles.Add(file.FullPath);
return directoryNode;
The line i'm using to Tag is:
file_tree_node.Tag = "file";
So i know what is "file" then i make a simple check if the Tag is not null then i know it's a "file" if it's null then it's directory.
For example this is how i'm checking if it's file or directory after getting all the content from my ftp server:
if (treeViewMS1.SelectedNode.Tag != null)
string s = (string)treeViewMS1.SelectedNode.Tag;
if (s == "file")
file = false;
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
else
RemoveDirectoriesRecursive(treeViewMS1.SelectedNode, treeViewMS1.SelectedNode.FullPath);
I also update in real time when getting the content of the ftp server xml file on my hard disk with the treeView structure information so when i'm running the program each time it will load the treeView structure with all directories and files.
This is the class of the xml file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Windows.Forms;
namespace FTP_ProgressBar
class TreeViewXmlPopulation
// Xml tag for node, e.g. 'node' in case of <node></node>
private const string XmlNodeTag = "node";
// Xml attributes for node e.g. <node text="Asia" tag=""
// imageindex="1"></node>
private const string XmlNodeTextAtt = "text";
private const string XmlNodeTagAtt = "tag";
private const string XmlNodeImageIndexAtt = "imageindex";
public static void DeserializeTreeView(TreeView treeView, string fileName)
XmlTextReader reader = null;
try
// disabling re-drawing of treeview till all nodes are added
treeView.BeginUpdate();
reader = new XmlTextReader(fileName);
TreeNode parentNode = null;
while (reader.Read())
if (reader.NodeType == XmlNodeType.Element)
if (reader.Name == XmlNodeTag)
TreeNode newNode = new TreeNode();
bool isEmptyElement = reader.IsEmptyElement;
// loading node attributes
int attributeCount = reader.AttributeCount;
if (attributeCount > 0)
for (int i = 0; i < attributeCount; i++)
reader.MoveToAttribute(i);
SetAttributeValue(newNode,
reader.Name, reader.Value);
// add new node to Parent Node or TreeView
if (parentNode != null)
parentNode.Nodes.Add(newNode);
else
treeView.Nodes.Add(newNode);
// making current node 'ParentNode' if its not empty
if (!isEmptyElement)
parentNode = newNode;
// moving up to in TreeView if end tag is encountered
else if (reader.NodeType == XmlNodeType.EndElement)
if (reader.Name == XmlNodeTag)
parentNode = parentNode.Parent;
else if (reader.NodeType == XmlNodeType.XmlDeclaration)
//Ignore Xml Declaration
else if (reader.NodeType == XmlNodeType.None)
return;
else if (reader.NodeType == XmlNodeType.Text)
parentNode.Nodes.Add(reader.Value);
finally
// enabling redrawing of treeview after all nodes are added
treeView.EndUpdate();
reader.Close();
/// <span class="code-SummaryComment"><summary>
/// Used by Deserialize method for setting properties of
/// TreeNode from xml node attributes
/// <span class="code-SummaryComment"></summary>
private static void SetAttributeValue(TreeNode node,
string propertyName, string value)
if (propertyName == XmlNodeTextAtt)
node.Text = value;
else if (propertyName == XmlNodeImageIndexAtt)
node.ImageIndex = int.Parse(value);
else if (propertyName == XmlNodeTagAtt)
node.Tag = value;
public static void SerializeTreeView(TreeView treeView, string fileName)
XmlTextWriter textWriter = new XmlTextWriter(fileName,
System.Text.Encoding.ASCII);
// writing the xml declaration tag
textWriter.WriteStartDocument();
//textWriter.WriteRaw("\r\n");
// writing the main tag that encloses all node tags
textWriter.WriteStartElement("TreeView");
// save the nodes, recursive method
SaveNodes(treeView.Nodes, textWriter);
textWriter.WriteEndElement();
textWriter.Close();
private static void SaveNodes(TreeNodeCollection nodesCollection,
XmlTextWriter textWriter)
for (int i = 0; i < nodesCollection.Count; i++)
TreeNode node = nodesCollection[i];
textWriter.WriteStartElement(XmlNodeTag);
textWriter.WriteAttributeString(XmlNodeTextAtt,
node.Text);
textWriter.WriteAttributeString(
XmlNodeImageIndexAtt, node.ImageIndex.ToString());
if (node.Tag != null)
textWriter.WriteAttributeString(XmlNodeTagAtt,
node.Tag.ToString());
// add other node properties to serialize here
if (node.Nodes.Count > 0)
SaveNodes(node.Nodes, textWriter);
textWriter.WriteEndElement();
And this is how i'm using the class this method i'm calling it inside the CreateDirectoryNode and i'm updating the treeView in real time when getting the ftp content from the server i build the treeView structure in real time.
DateTime last_update;
private void UpdateList(TreeNode tn_rt)
TimeSpan ts = DateTime.Now - last_update;
if (ts.TotalMilliseconds > 200)
last_update = DateTime.Now;
treeViewMS1.BeginUpdate();
treeViewMS1.Nodes.Clear();
treeViewMS1.Nodes.Add(tn_rt);
TreeViewXmlPopulation.SerializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
ExpandToLevel(treeViewMS1.Nodes, 1);
treeViewMS1.EndUpdate();
And when i'm running the program again in the constructor i'm doing:
if (File.Exists(@"c:\XmlFile\Original.xml"))
TreeViewXmlPopulation.DeserializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
My question is how can i update the xml file in real time like i'm doing now but also with the Tag property so next time i will run the program and will not get the content from the ftp i will know in the treeView what is file and what is directory.
The problem is that now if i will run the program the Tag property is null. I must get the ftp content from the server each time.
But i want that withoutout getting the ftp content from server to Tag each file as file in the treeView structure.
So what i need is somehow where i;m Tagging "file" or maybe when updating the treeView also to add something to the xml file so when i will run the progrma again and read back the xml file it will also Tag the files in the treeView.

How to find out image size (in pixels) of jpg and gif files

this seems to work, though i doubt that it would very time:

               int w = img.getWidth(null);
               int h = img.getHeight(null);
               while(w <= 0 || h <= 0)
                  try{Thread.sleep(10);}catch(InterruptedException ix){}
                  w = img.getWidth(null);
                  h = img.getHeight(null);

We've a requirement that we need to find out the size of a java object at run time, is there a direct java API to get the size of a composite object in memory?
Here is my requirement: We are adding string objects (which is an xml string of considerable size) into a List. After reaching certain size limit (lets say 5MB) of the list i need to put this data into DB as a CLOB. So every time I add a string object to the list, I need to see if the total size of the list exceeds the limit and if yes, flush the results into DB.
I am not sure if java has a direct API for this, if not what is the beast way to do it, it s critical requirement for us.
It would be really great if someone could help us out.
>
Could you explain your actual requirement a little more fully.
1. Is each individual string a separate XML string? Or is it just a fragment? Why would you just concatenate them together into a CLOB? That won't produce valid XML and it won't let you easily separate the pieces again later. So provide a simple example showing some strings and how you need to manipulate them.
2. Are you using these xml strings in Java at all? Or are you just loading them into the database?
For example if you are just loading them into the database you don't need to create a list. Just create a CLOB in Java and append each string to the CLOB. Before you append each one you can check to see if the new string will put you over your length limit. If it will then you write the CLOB to the database, empty the CLOB and start appending again to the new clob instance.
If you explain what you are really trying to do we might be able to suggest some better ways to do it.

How to save copyright information into Gif files?

URGENT - can someone please help. i have photoshop cc and I need to know how to copyright my gif files

c. is correct in that it's a little ambiguous what you're trying to achieve. Here are three ways:
Under US law your image is already copyrighted at the moment you create it, but you greatly improve your legal standing in court if you register the image with the US Copyright Office.
To add invisible copyright metadata inside an image, choose File > File Info in Photoshop, click the Description tab, and fill out Copyright Status and Copyright Notice. Then do what c. said in Save for Web to make sure it's included on export. However, while this works with most formats including JPG and PNG, I do not think it will work with a GIF. As far as I can tell, GIF doesn't support metadata. If you want better support for modern standards for non-photographic web graphics, use PNG instead of GIF.
To add a visible copyright watermark over the image, download the Adobe Watermark panel and install it.

HOW CAN I   WRITE   TEXT IN A     FILE

HI,
I have problems with saving files on my hard disk with an JAVA Applet.
Do you know how to do it in the best way?
here is the code i'm trying:
public String getCount()
      int count=456;
      String rec=null;
      DataOutputStream dos = null;
      try
        URL                url;
        URLConnection      urlConn;
        url = new URL(getCodeBase().toString() + "counter.txt");
        urlConn = url.openConnection();
        urlConn.setDoOutput(true);
        urlConn.setUseCaches(false);
        urlConn.setRequestProperty ("Content-Type", "application/x-www-form-urlencoded");
        rec=""+count;
        dos = new DataOutputStream(urlConn.getOutputStream());
        dos.writeChars(rec);
        dos.flush();
        dos.close();
       catch (MalformedURLException mue) { return mue.toString(); }
       catch (IOException ioe) { return ioe.toString(); }
      return rec;
    }this code is simply saving the value ot count in the file "counter.txt"
I think the problem comes at the line: dos = new DataOutputStream(urlConn.getOutputStream());
It doesn't throws exception, it just stopes there and doesn't show any result.
WHY?
If you have some ideas ...thanks.
the class DataInputStream is working perfectly. I'm reading, but saving does not work.

You're using getCodeBase() to construct the file name, apparently, so I guess you are wanting to write to a file on the server where the applet was loaded from. And it looks like you're trying to do a POST to the URL that you construct, or something like that. But the URL ends in ".txt" so most likely your server isn't exposing that URL to the outside world.
You're on the right track, but you need to write to a URL that can accept POST requests and knows what to do with them. You can't just write to a file on the server -- if you could do that in your applet then anybody in the world could do it from a simple program, so consider the security implications of that.
