Is it possible to read pixels of gif in java

Does anyone know about gif files and reading them?
If you have a gif file and there are blue dots on the gif file. What do you do to check to see if a pixel is a certain color/attribute, ie blue... ? Please give code only - many other posts are general and obvious -. No acme.

Load the Image with Toolkit and MediaTracker,
create BufferedImage: BufferedImage image = new BufferedImage(loadedImage.getWidth(null),loadedImage.getHeight(null), BufferedImage.TYPE_...);
Then get the image's Raster: Raster raster = image.getRaster();
Now read pixels: raster.getPixel(x,y, intArray)
where intArray is to receive the sample values of the pixel (with ARGB 4 values ...)
Look at Core Java, Vol II

Possible to read/ write word files using Java?

I'm planning to write a Java application that can read an MS word document, extract something (including mathematics equations created with the equation editor) from the document and write it to another word document.
Is it possible to do this?
Can anyone give me some idea?
Any idea is much appreciated :)

I think I may have misunderstood your question, but in case I didn't and you find this helpful, following is the code to read a word doc, replace certain strings, then write it out as a new doc.
import java.io.*;
public class Copy {
     public static String endResult;
     public static void main(String[] args) {
          String oldAuthor = "Samuel Foote";
          String newAuthor = "New Author";
          String oldDate = "1720-1777";
          String newDate = "1975 -- ";
      try {
          File inputFile = new File("C:\\document.doc");
          BufferedReader input = null;
          input = new BufferedReader(new FileReader(inputFile));
          StringBuffer contents = new StringBuffer();
          String line = null;
          while ((line = input.readLine()) != null){
               contents.append(line);
               contents.append(System.getProperty("line.separator"));
          String text = contents.toString();
//     Replace the author and the dates
          Copy y = new Copy();
          y.replace(text, oldAuthor, newAuthor);
          text = endResult;
          y.replace(text, oldDate, newDate);
//     Copy the new, improved text to another file     //
          Copy z = new Copy();
          z.finalReplace(text);
          input.close();
     catch (FileNotFoundException ex) {
          ex.printStackTrace();
     catch (IOException ex){
          ex.printStackTrace();
     String replace(String text, String oldSubstring, String newSubstring) {
//          Search the text for a string, then replace it //
          int fromIndex = 0;
          int e = 0;
          StringBuffer sb = new StringBuffer();
          while ((e = text.indexOf(oldSubstring, fromIndex)) >= 0) {
               sb.append(text.substring(fromIndex, e));
               sb.append(newSubstring);
               fromIndex = e + oldSubstring.length();
          sb.append(text.substring(fromIndex));
          endResult = sb.toString();
          System.out.println("final string = " + sb);
          return sb.toString();
     String finalReplace (String args) throws IOException {
//          Move the altered text to a new file //
          File outputFile = new File("C:\\copied document.doc");
          FileWriter out = new FileWriter(outputFile);
          Writer output = null;
          try {
               output = new BufferedWriter(new FileWriter(outputFile));
               output.write(endResult);
          finally {
               if (output != null) output.close();
             return endResult;

Generating Animated GIF in java is it possible

Hi,
I have worked on generating GIF / JPG Files in java. Now that i would like to know if its possible to create animated GIF in java. I have'nt got any examples on that. If anyone has any, can you pl post them here?

This is an animated gif encoder : http://jmge.net/java/gifenc/
Animated GIF Example :
import net.jmge.gif.Gif89Encoder;
void writeAnimatedGIF(Image[] still_images,
String annotation,
boolean looped,
double frames_per_second,
OutputStream out) throws IOException
Gif89Encoder gifenc = new Gif89Encoder();
for (int i = 0; i < still_images.length; )
gifenc.addFrame(still_images);
gifenc.setComments(annotation);
gifenc.setLoopCount(looped ? 0 : 1);
gifenc.setUniformDelay((int) Math.round(100 / frames_per_second));
gifenc.encode(out);

I have an external hard drive, from Iomega. that I can open and see my files. However, I cannot copy or save any file to it. On my PC I have it says that is possible to read and write in it, but in my Mac, it says I can only read. can somebody help me?
Also, Im a photographer, so I like to name a lot of files at the same time (used to do in on PC and it was very usefull.) cannot find out how to do it on my Mac. Really appretiate if some one can give me a solution! Thanx

Your drive is formatted with the NTFS file system. OS X can read but not write to the NTFS file system. There are third party drivers available that claim to add the ability to OS X to write to an NTFS partition. I have not tried them and don't know if they work.
The only file system that OS X and Windows can both write to natively is the FAT32 file system.

Sychronisation AD - OID: Is it possible to read the user password from AD?

Hi.
We are using the Oracle Internet Directory shipped with the Oracle 9i Database Rel. 2 (9.2.0.1).
I try to synchronise the user accounts from AD to OID using JAVA JNDI. I'm able to read all necessary user information except the user password (MD5 value). Even if I connect to the AD using SSL, it's not possible to read the attribute userPassword.
Is anybody out there who got this work or knows a way (may also be by the use of another programming language or tool) to get the user password out of AD? Is this possible? How does the Oracle Integration Agents accomplish this?
Thanks in advance.
Hermann S.

Hermann,
I am working with this as well, though from AS10g, not RDBMS. According to the OID Administrator Guide chapter 43, page 43-52:
<snip>
Synchronizing passwords from Microsoft Active Directory to Oracle Internet Directory is not possible in the Oracle Application Server 10g release because passwords in Microsoft Active Directory are not accessible by LDAP clients. However, if a deployment requires passwords to be available in Oracle Internet Directory, then the following two methods are recommended:
Build a custom plug-in for Microsoft Active Directory that captures a password change and synchronizes it with Oracle Internet Directory
Manage Active Directory passwords from the Oracle environment. This enables passwords to be available in both Oracle Internet Directory and Microsoft Active Directory because the Active Directory connector can synchronize passwords from Oracle Internet Directory to Microsoft Active Directory.
</snip>
As10g can however look up the password in AD using the "Active Directory External Authentication Plug-In". This is documented in the same chapter.
Hope this helps,
Jens

Hello Blake,
Try this:
READ TABLE lt_action_fld WITH KEY STATUS = '0' BINARY SEARCH.
wf_index = sy-tabix.
loop at lt_action_fld from wf_index.
if lt_action_fld-status ne '0'.
exit.
endif.
delete lt_action_fld index wf_index.
endloop.
Let us know, if this helps.

Is it possible to read digital data using an external clock (PCI-6259 M)?

I’m using a NI PCI-6259 M Series card and trying to write my program in VC++6.0 using the functions in the DAQmx driver.
Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?
Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present.
Example 1
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxCfgChangeDetectionTiming(m_ReadTrimTask,"Dev1/port2/line6","Dev1/port2/line6",DAQmx_Val_FiniteSamps, 10);
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);
Example 2
// Create tasks
Status = DAQmxCreateTask("", &m_ReadTrimTask);
// Set up read task
status = DAQmxCreateDIChan(m_ReadTrimTask, "Dev1/port2/line0", "", DAQmx_Val_ChanPerLine);
status = DAQmxSetSampTimingType(m_ReadTrimTask, DAQmx_Val_SampClk);
status = DAQmxSetSampClkRate(m_ReadTrimTask, 1000.0);
status = DAQmxSetSampClkActiveEdge(m_ReadTrimTask, DAQmx_Val_Falling);
status = DAQmxSetSampClkSrc(m_ReadTrimTask, " Dev1/port2/line6");
// Read data
int32 sampsPerChanRead, numBytesPerSamp;
status = DAQmxReadDigitalLines(m_ReadTrimTask, 10, 10.0, DAQmx_Val_GroupByChannel, result, 10, &sampsPerChanRead, &numBytesPerSamp ,NULL);

Hello Magnus,
Thank you for contacting National Instruments.
"Question1: Not all functions listed in the NI-DAQmx C Reference Help seems to be supported by my NI-card, where can I find information about which of the functions that are supported?"
The best place to look for this information would be the M Series Help Manual. There you can find the features of your PCI-6259 and what operations it supports.
"Question2: I want to read data from a device that clock out data on the falling edge of a clock signal. The clock signal and the data signal are routed to two DIO terminals on the NI-card. The question is if it is possible to read data using the clock as a sample clock? See two code examples below that doesn’t work. In both cases 10 samples are read at once, even if the external clock is not present."
Look at the "ContReadDigChan-ExtClk_Fn.c" example project which ships with the NI-DAQ driver. This is located at: C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Read Values\Cont Read Dig Chan-Ext Clk.
You will have to make some minor modifications to convert this to a finite acquisition, but that is simply a matter of changing the "sampleMode" parameter of the DAQmxCfgSampClkTiming() function. You will also have to route your clock signal to a PFI line and specify which line in your code.
I hope this helps.

Is it possible to read archive files outside of SAP?

Hi Experts,
I would like to read SAP archived data (*.ARCHIVE.ARCHIVING) with non-SAP application. I already know, that data is automatically compressed (and maybe encrypted?).
My question: Is there some possibility to read archive files outside of SAP? I suppose that would be needed to do some decompress first.
Your help is appreciated. Thank you!
Jan

Hi Stefan,
Thanks for your reply. I found some points with your hint. Some summary for others:
460620 - Migrating archive files:
"Archived data may have to be migrated. One solution is to perform an SLO service archive migration. You can also perform an archive migration for archive files using the Archive Development Kit (ADK)."
153433 - Access to archived data from other logical systems
"For data security reasons, the ADK checks whether an archive file was created in the same system and client where it is to be read. If the client, system or file key do no longer correspond to the meta data that were valid at the time of archiving, you can no longer always access the archive file, particularly for reloading. If only the system ID changes when a new installation due to a system copy is carried out, read accesses are still possible. No solution is provided in the standard system. The access to archive files from other logical systems must be taken into account and carried out in a migration project."
Unfortunately, I still do not know if it is possible to read archived data outside of SAP.
Best Regards,
Jan

Is it possible to read the file using File Adapter which is in client machi

Is it possible to read the file using file Adapter which is in client machine(on the same network).Then what is thee need of FTP Adapter?

You can achieve that by exposing your client machine as a drive, then you can go using file adapter.
FTP adapter will help you to communicate with different machine which is in different network.
It is considered good etiquette to reward answerers with points (as "helpful" - 5 pts - or "correct" - 10pts).

1.is it possible to read a .xls file and load it into an oracle table

1.is it possible to read a .xls file and load it into an oracle table, using oracle database or oracle forms i.e. either utl_file, or text_io, or any other oracle tool.
As far as I know we need a csv file or a txt ( tab delimited) file ?
2.Are there any windows tools for the same

Hi,
If you want to use the DDE package to read the XLS file then yes, you will neeed to know the number of rows and columns in the input file.
i.e. How will you know :
1) How many columns are there in the input file.
If I have a XLS file with the following data :
R1C1 R1C2 R1C3 R1C4 R1C5 R1C6 R1C7
xxx xx x
Where R represents row and C represents column, then how will you know the each row has 7 columns. If you know the answer upfront, then it's not a issue.
Using the DDE apprach, you will have to specify the RowNum and the ColumnNo of each idividual cells to read/write data from xls sheet.
Look at the syntax in my ealier post.
using the other approch (i.e. comma delimited text file - CSV file) , you need not know the number of columns as you can loop thru the input record till the last column is read.
All you have to do is to look for the 'n' occurances of the field delimiter say ',', do a substr from the current position to the point where the ',' was found.
This process is to be repeated in a loop till all columns are read.
The TEXT_IO package can trap for EOF (End Of File).
Hope I made myself clear.

Is it possible to read the description of videos that you can see in iTunes on your iPod Touch 4th Gen or 5th Gen?

I was wondering if it's at all possible to read the description of videos that you have on your iPod Touch 4th or 5th Generation. It's available on iTunes, but I was wondering if there was a way to see it on your actual device.
Any answer would be a great help! Thanks

You can omit the title altogether in the URL (together with the succeeding slash, of course). For example, my own podcast URL in the Store is
https://itunes.apple.com/gb/podcast/the-sound-of-78s/id166389425?mt=2
but this works perfectly well:
https://itunes.apple.com/podcast/id166389425
Indeed you can even put your own title:
https://itunes.apple.com/podcast/any_old_title/id166389425
So it's as simple as that!
