Image Reading Writing from TIFF format

I have tiff files which contain average 30 images, i want to split it in batch. batch can be of 5 images or 10 images, it can be varry.
Pls Help....

Java ImageIO can do this for you. You'll need to do a bit of reading about it, there is plenty to digest on this forum and in various parts of the internet.
If you have any further, more specific questions, please ask.

TIFF-VIs for reading/writing from/to files

To whom it may concern,
I'm looking for TIFF-VIs for reading/writing from/to files
for Labview 6 without any add-on package.
Unfortunately I can't use TiffRd04 and TiffSv05 from
Koji Ohashi due to the different file format!
Any hints?
Thank you in advance. Best regards from Germany

Hi Udo,
did you check these TIFF related libraries? .. maybe one of them is working.
Good Luck

Reading & Writing from/to OCR

Hi,
Is there a way to read and write the Oracle Cluster Registry.
Are there any API's available for the same.
Thanks

whatis wrote:
I have a SW application running on all nodes in the RAC Cluster.
The SW needs to write data to a place which is visible to all and can be read by all the other nodes. Also it should be able to gather information (especially about failover), so should be able to read from it.The OCR is not used to as a common data store for CRS applications - that is typically what a cluster file system is used for. This allows the same set of directories and files to be visible to applications on each and every cluster node.
The OCR is specific to CRS and should only be used by CRS software.
I found this link on the internet 'C Application Programming Interface to Oracle Clusterware'
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/crsref.htm#CHECGHGI
Yes, if you want to create a cluster application that you want to be managed via CRS. But this requires more thought than simply slapping a few calls together in an application to make it cluster enabled.
Is this the correct way to do it? Can reading/writing from/to OCR lead to fatal errors?Unsure whether it is the correct way for the problem you're trying to solve as that problem is pretty still much unknown to us as you have not described it.
Can one corrupt the OCR? Not if the API calls are used and used correctly.
It is a bit strange to see a posting about using the CRS API itself - usually we write our software in the RAC layer (as PL/SQL and Java stored procedures, using the cluster features of the database instances).
Do you intend to only use CRS? Or CRS with ASM and RAC? And why do you want external C application code to make use of cluster services?

Reading & writing from MS Excel files in Webdynpro ABAP

Dear experts,
We have a requirement to read and write from an MS excel file in a Webdynpro ABAP based application. The application would be deployed on WAS (Web Application Server) which is running as part of SAP ECC on UNIX platform.
What is not clear is
1) If we store the MS Excel template on the server which has UNIX, will the file be recognised for reading/writing programmatically in Webdynpro ABAP? If this works, we have a requirement where the end users will download the excel template and upload the same after filling data into the excel file. The data filled into the excel has to be read and updated in the SAP backend (ECC).
2) There is an article on "Modifying Excel using WD ABAP" at the following link
https://wiki.sdn.sap.com/wiki/display/WDABAP/ModifyingexistingexcelsheetusingWDABAP
But again it is not clear whether this approach will work on Unix based SAP server (ECC WAS).
Thanks
Suresh

I don't know if there is an application in Unix that can read Excel files - if that is what you are asking. However that has nothing to do with this forum. If you are uploading the file to ABAP using Web Dynpro ABAP, then it doesn't matter what Operating System the server is running on. Unix, Linux, Windows - all the processing is done in ABAP and is OS independent. The actual reading of the file in ABAP involves reading either an XML or Text Tab Delimited version of the Excel file however - if you read through the links on manipulating Excel in ABAP.

I think you should test this with one or two pictures - import/convert, save metadata to file, geotag, read metadata. Also try import/convert, make small adjustment, save metadata to file, geotag, read metadata. In iView I often write metadata to DNG's that have been adjusted, then read the metadata in Lightroom - sometimes I add more data in iView and do more adjustments.
I have seen the problem you describe, but it has been with raw files which I have adjusted in Lightroom but haven't saved out the metadata. I have then created an xmp sidecar in iView, and read the metadata in LR. So the sidecar had no ACR/LR instructions. The result was that my adjustments were wiped out. What I suspect is that something similar is happening with your DNGs - that conversion creates them but doesn't write the ACR/LR fields.
So try a few alternative sequences.

How to read data from PC format external disk, using Labview MAC

Hi folks,
For years I have not been able to read data files from a PC formatted (created) external disk, using Labview for Mac. More specifically:
- I have Labview 7.01 running on OS X 10.4.11 on a PowerBook G4
- I have a 500GB external USB/firewire disk that was formatted on a PC and has data files (custom format) that were created on the PC. I believe that C code actually creates the files, but Labview 7/PC opens the files and appends some info (I don't think the fact that C or Labview touches the files is actually relevant to this issue though).
- I can connect the 500 GB disk to my mac, and it will mount just fine and OS X can see all of the data files (and anything else on the disk).
- if I use my Labview app to open and read a data file it fails:
- open/create/replace.vi (with read-only access) shows a file dialog window that lets me navigate to any file on the external disk.
- but, the vi returns an error 7
- if I use OS X to copy the data file to my Mac disk, my Labview app works fine.
So, does anyone know if:
- I'm just doing something wrong in my Mac Labview app?
- Labview 7.x solves this problem?
- Labview 8/Mac solves this problem?
- OS X 10.5 solves this problem; with Labview 7 or 8; or does OS X 10.5 worsen the problem?
Thanks, in advance...

Hi kehander,
Thanks for the reply. I tried filling a constant path with the Mac-defined path to a data file on the USB disk (ie "DATA2:file1.dat"). This resulted in the same error message.
I then considered that maybe I was misinterpreting the LV error message, and that perhaps I was supposed to address the file using PC-notation (ie. "DATA2\file1.dat"), even though the app is running on a Mac. No joy with this, but I get a different error msg:
"Error 1430 occurred at Open File
Possible reason(s):
LabVIEW: The path is empty or relative. You must use an absolute path."
Can you share what your reasoning was for your suggestion... I'm not sure I understand why a constant path would produce different results?

Reading/writing from the standard streams of a process

Hi all
I try to start an external program trough my java application and then try to communicate it. After the external process has started, I want to send input to it and get output back from it. That, however, doesn't work.
My external process gives some output data when it starts up, and i can catch this with no problem at all.
Thing is, my program hangs while reading from the stream when there is no more to read from it. How can I read and write to the streams without it stopping and hanging?
Here is some source code I use to test this:
//The constructor
   try {
     ProcessBuilder pb = new ProcessBuilder(args);
     //I combine the error stream with the output now, just to get stuff to work. Will change later
        pb.redirectErrorStream(true);
     Process p = pb.start();
     input = new BufferedReader( new InputStreamReader(p.getInputStream()));
     output = new DataOutputStream(new BufferedOutputStream(p.getOutputStream()));
     String line = null;
       //I get this far, but after the last line of input has been read, I the program seems to stop in this while loop
     while( ( (line = input.readLine()) != null) )
               System.out.println(line);
     }catch(IOException e) {
               e.printStackTrace();
//This is code for communication with the process after it's started
   output.writeBytes(id);
   String t = null;
   while( (t = output.readLine() ) != null)
          System.out.println(t);
   String line = null;
   ret[0] = output.readLine();
   while( ( (line = output.readLine()) != null) && (!line.startsWith("[")))
       ret[1] += line;
   ret[2] += error.readLine();
   while( (line = error.readLine()) != null)
     ret[3] += line;

You either have to do read and write in two different threads.
Or if you can modify your external program you can implement some protole which tels the reader that message is orver (Ex:- "OVER" word used when using halfduplex communication devicies)
Or you should meke your program smart enough to understand the external program so it can decide whether there are more data to be read by looking at the data which is already read.
Or you can use the method available() in the input stream which return the number of bytes that can be read without blocking. But this can be problamatic since when you call it it mighe return 0 when there are no data at the your end of the pipe but the external program is actually writing to the pipe

How does the TIFF format compress images?

When we choose "File> Save As" to save an image to a TIFF file, a TIFF Options dialogue box appears with 4 image compression options( None, LZW, Zip, Jpeg). What is this for? Does the TIFF format compress images? Are they destructive to the image quality? THANK YOU

If you select no compression, it will take up too much space, guaranteed. TIFF lets you pick any compression method supported by your program and the viewing program. Some are lossy, some are lossless. Most TIFFs tend to be compressed in LZW or ZIP, both of which are lossless. You can also choose to compress your TIFF using JPEG compression, which is lossy, but I can't imagine why you would do this instead of simply saving as a JPEG file, which is more likely to be properly opened in browsers than a JPEG-compressed TIFF file.
And in response to one of the previous posts, not all compression throws away details from your file. Only lossy compression (e.g., JPEG, or in the music area MP3) throws away data. The lossless compression techniques simply encode the data in fewer bits if possible. (One important fact not relevant to the web, where you will use 8-bit-per-channel files: If your photos are 16-bit-per-channel, don't save in LZW compressed format; they will actually become larger than the uncompressed image.) For a simplified example, if there is a series of 16 pixels of solid white, a losslessly compressed image will have code that says, in effect, 16 pixels of (255,255,255) using an abbreviated code instead of simply listing (255,255,255) sixteen times. It builds up a directory of byte combinations and can use just a few bytes to refer to many bytes of image data. Because the coding and decoding is exact, there is no change in the image data when it's opened.
JPEG is a lossy compression technique that doesn't actually record pixel values at all. It uses formulas to specify averages and changes within regions. In effect, it records the fact that a given group of pixels has values centered on X color, and that the upper left is much pinker and the lower right is much greener than the average. When you pick the degree of quality for JPEG compression, you tell it how small to make the comparison cells. As you can imagine, if the image has text, tree branches, or other highly contrasty subject matter, this will cause serious weirdness if the comparison cells aren't very small (i.e., you don't have the quality set to max).

I need to crop image in TIFF format. what product i need to buy

i need to crop image in TIFF format. what product i need to buy

Photoshop should be able to handle cropping your TIFF file, possibly Photoshop Elements as well which would cost less. You should get the trial version to make sure rather than buying before trying.
You might also want to check if you already have something on your machine that can do it. On a PC you should be able to right click the image and choose "Open With" whereby a menu of programs should appear with programs that can open the file. You can check to see if any of those listed provide the cropping tool.
If you have further questions you should try posting in the Photoshop forum instead of here (http://forums.adobe.com/community/photoshop?view=discussions). This forum is primarly for questions about downloading and installing Adobe applications.
