Display image from binary code in web service(Sharepoint portal)

Hi All,
We have converted a BAPI into web service.We are able to access it and fetch the data in sharepoint portal. The content which gets published in the sharepoint needs one image also to get displayed.The problem is we have the binary format but we are not able to decode that and display that as image in sharepoint portal.
We are using VS2003 to make the portal component and then deploy it in sharepoint portal.We are stuck how to decode the binary format and display the image.
Any Help will be appreicated.
Regards
Sachin

Displaying image from binary code

I am converting a image file(jpg) into a binary file and sending it. In the receiving side i get the binary file and want to display the image in the applet or store the image in a file. while trying to do this i am not able to read the image from the buffer. Below here i have given my code.
      File f= new File("image.jpg");
       FileInputStream fis = new FileInputStream(f);
       byte [] buffer = new byte[(int)f.length()];
       fis.read(buffer,0,buffer.length);
       fis.close();
      File f1 = new File("input.txt");
      int length = buffer.length;
      PrintWriter pw;
       pw = new PrintWriter(new BufferedWriter(new FileWriter(f1)));
      for(int i=0;i<length;i++)
          pw.println(Integer.toBinaryString(buffer));
pw.flush();
pw.close();
converting back to image i get error
File f1 = new File("inp.txt");
FileInputStream fis = new FileInputStream(f1);
buffer = new byte[(int)f1.length()];
fis.read(buffer,0,buffer.length);
Toolkit tk = Toolkit.getDefaultToolkit();
img = tk.createImage(buffer);
Reply me as early as possible.thanks.

You have two glaring problems here.
Firstly, you are writing via writers, which are intended for text and are probably corrupting your data. You want to be using a FileOutputStream.
Secondly, when reading in you are not checking the number of bytes read and may well not be fully populating your array. You want to change your reading code to something like this,
    buffer = new byte[(int)f1.length()];
    int read = 0;
    while (f1.available() > 0)
        read += fis.read(buffer, read, buffer.length - read);
    }

Displaying image from binary data using java

hi there,
i have created a swing applet displays me a url, what the url returns me is the image in binary format, and i want to show the complete image using that binary data
so how do i do it.
some thing like this :
URL url = new URL("http://192.168.1.1:8086/file-storage/download/Zerg.jpg?version_id=35688");
JEditorPane jep = new JEditorPane();
jep.setPage(url);
output is in binary on my applet window.

Hey,
This displays an image from a url, you could check if your url is and image or not using URL.getFileName() and see if it ends in gif jpeg etc. and then display it this way.
hope it helps

How to retrieve and display image from database in a web page

Hi all;
I have been trying this for some time now. I have found some tutorials so far but none of them addresses my concern. Here it is:
I have built a web application that can connect to an Oracle DB.
I have a table called "employee", where I record any employee details, among which the employee picture. I stored the pictures and the finger prints using "Oracle sql developper" as blob type.
How can i retrieve and view all these information when i run the application?
I can easily retrieve all other types of value, but the image(BLOB type) has been a nightmare for me.
HELP PLEASE.

I believe your Binary Large Obejct will come back as an array of int, and you'll need to use BufferedImage it's associated API to get it to a viewable image configuration.I don't think BufferedImage immediately solves the problem -- this is a web app, so I assume the image will be displayed using the HTML IMG tag.
Solution: google. There are many example of how to do this. For example, any book on servlets will have an example of dishing up a dynamic image.

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at low resolution. The camera on my phone works fine, but any web related photo content is now pixelated and low res, what's the deal?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at a low resolution. I have IOS 7.0.4. My phone camera works fine, but any web based photo content from Safari, Yahoo images, Google images, and Flickr all come in pixelated and low res. What's the deal?

It happened to me but later I figured out that cellular signal was not that great and so the Internet was very slow. It took me about 2 minutes to get the full resolution picuture on either of the app you've described. Try to get faster internet either by wifi or good signal and then check.

Problem Displaying image from blob

Hi all,
I m using,
Database : 10g Rel 2
Frontend : DevSuite 10g
OS : WinXp
Browser : IE 6
Problem : In my forms i m displaying images from blob column but some of the images are not displayed. I have tried with all image formats available in combination with all available display quality but no luck. What could be the reason for it and how do i solve it?
Can anyone help me plz?
Thnx in advance.

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

Display Images from HTMLDB_APPLICATION_FILES Table?

How do I display images from the HTMLDB_APPLICATION_FILES Table?
Are the contents full available potentially for display? Or only after I have written them to another display?
Please advise what I need to do or what corrections below is required:
The calling procedure is a item in a SELECT statement as part of a report query:

<(img src="#OWNER#.download_HAF_file?p_file= ' || nvl(ID,0) || ' height="50" width="50" )>, HAFimg<P>

I believe you put HTML "pre" tags around your quote (with square brackets, I can't type them here because they'll be escaped).
If the example below looks formatted then using "pre" works, if not...then ignore me ;)
begin
select
    count(*)
into
    v_count
from big_table;
end;

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.

Don't store the images in the database. Store the image file names in the database and put the images in a folder.

It is working upto "working".
If any body has any solutions please post.

[Forum FAQ] How to display an image from Http response in Reporting Services?

Question:
There is a kind of scenario that users want to display an image which is from URL. In Reporting Services, if the URL points to an image file, we can directly display it by typing the URL in embedded image. However, some URLs are just sending Http requests
to server side, then redirect to another position and the server will return the image. For these kind of URLs, Reporting Services can’t directly render the image from Http response.
Answer:
To achieve this goal, we can add custom code into the report. Pass the URL as argument into our custom function so that we can create HttpRequest and get the HttpResponse. Then we can use custom function to return the Bytes() from the HttpResponse and render
it into an image in report.
Ps: In Reporting Services, it only support drawing Bytes() array into image, so we need to have our custom function return Bytes array.
Add the assembly and custom code into the report.
Public shared Function GetImageFromByte(Byval URL as String) As byte()
                Dim photo as System.Drawing.Image
         Dim Request As System.Net.HttpWebRequest
       Dim Response As System.Net.HttpWebResponse
              Request = System.Net.WebRequest.Create(URL)
                 Response = CType(Request.GetResponse, System.Net.WebResponse)
             If Request.HaveResponse Then
                  If Response.StatusCode = Net.HttpStatusCode.OK Then
                       photo = System.Drawing.Image.FromStream(Response.GetResponseStream)
                 End If
            End If
              Dim ms AS System.IO.MemoryStream = new System.IO.MemoryStream()
             photo.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
                Dim imagedata as byte()
                imagedata = ms.GetBuffer()
                return imagedata
End Function
Grant the permission for assemblies.
Go to:
C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\RSpreviewPolicy.config
C:\Program Files\Microsoft SQL Server\MSSQL\Reporting Services\ReportServer\rssrvpolicy.config
Give “FullTrust” for Report_Expressions_Default_Permissions.
Insert an image into report.
Expression:
=Code.GetImageFromByte("https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSrVwPoAtlcA2A3KaiAJi-XjS4icr1QUnKYr7uzpX3IL3g2GPisAQ")

Hi, I'd like to display a dynamic image from the web inside a JLabel or any other swing component it could work in. I've been looking on the Swing tutorials and others forums, all I can have is that a JLabel can load an Icon object, defined by an image URL, but can this URL be like "http://xxxxx/image.jpg" somehow or can it only be a local image URL?>
I do not know why you start talking about an image on the web then go on to show concerns about whether it will work for a 'local' URL.
But perhaps this answer will cover the possibilities.
So long as you can from an URL to the image, and the bytes are available for download (e.g. some web sites wrap a direct call to an image in HTML that embeds the image), the URL based icon constructors will successfully load it.
It does not matter if that URL points to
- a web site,
- a local server ('localhost'),
- an URL representation of a File on the local file system, or
- it is inside a Jar file that is on the application's run-time classpath.
How you go about forming a valid URL to a 'local resources' (or indeed what you regard as local resources) is another matter, depending on the form of the project, and how the resources are stored (see list above).
Probably the main reason that examples use images at a hard coded URL on the net is that it makes an 'image example' self contained. As soon as we compile and run it, we can see the result. I have posted a few examples like that on these forums.
