Loading image files

I know this may be a simple question because i just started with java but whenever i am trying to load a jpeg or another picture
file for an ImageIcon or something i hav to type the file pathname i.e. C:/Users/Zach/Documents/... i can do this but if i send sumone my program
it wont load the pictures cuz there path wont be the same. Ive tried just Name.jpeg but it always says the files doesnt exist unless i put a
full path in, my teacher cant help me because she knows nothing about java. So i was wondering if anyone could tell me a way to locate a file
on your computer so your program can get it without it being in an exact path or what im doing wrong.
Thanks

Something to think about anyway. In general one avoid using hard-coded file paths (for the reasons you mentioned) and instead uses urls to load resources with class loaders.
This has the advantage of working portably and in jars as well.

Failed to load image file-manager

Hello everybody,
I've recently install ArchLinux (0.6) on my machine. Then do a pacman -Sy and pacman -Su and fresh install xfree86, gnome and gnome-extra but when I run into gnome a window error appears:
error
Failed to load image file-manager
Details: file not found
I can't see mostly of the icons, like the foot of gnome in applications, the icon of file browser, the show desktop ..
what can it be?
well, thanks in advance.
Ps: xscreensaver should be added as a dependency when pacman -S gnome
Ps2: sorry my poor english

Yes, you're right.
To solve (until a next release) I done:
pacman -Rcd gtk2
pacman -A /var/cache/pacman/pkg/gtk2-2.4.0-1.pkg.tar.gz
And avoid to do pacman -Su ...
Thanks and bye.

How to delete a jar file after loading image files from it

Hi,
How can I delete a jar file after some image files have been loaded? For example, say, I have "a.jar" which contains an image "a.gif" in the root directory of the c drive. I would like to get the image size and then delete the jar file. Here is the code snippet:
    URL url = new URL("jar:file:/C:\\a.jar!/a.gif");
    Icon icon = new ImageIcon(url);
    System.out.println("icon size ? " + icon.getIconHeight());
    File file = new File("c:\\a.jar");
    while(file.exists())
        file.delete();
        try
            Thread.sleep(100);
        catch (InterruptedException ignored)
    System.out.println("file deleted.");I get the image size correctly but just can not delete the jar file. Apparently the file handle is not released, but how to close it? Any hint will be appreciated.
Justin Jan

I am sure the URLConnection.defaultUseCaches is set before it is connected otherwise I should catch an IllegalStateException on conn.setUseCaches(false).
        try
            URL url = new URL("jar:file:/C:\\a.jar!/a.gif");
         URLConnection conn = url.openConnection();
         conn.setDefaultUseCaches(false);
         conn.setUseCaches(false);
            Icon icon = new ImageIcon(url);
            System.out.println("icon size ? " + icon.getIconHeight());
            url.openConnection().getInputStream().close();
            System.gc();
         System.runFinalization();
            File file = new File("c:\\a.jar");
            while (file.exists())
                file.delete();
                try
                    Thread.sleep(10);
                catch (InterruptedException ignored)
            System.out.println("file deleted.");

Error in pda load image file performance in PDA

hello
i am using Windows CE with labview mobile module 8.6 in evaluation version. When trying to use "pda load imege file.vi" i get an error code 1, regardless of loading a .bmp, .gif or .jpg, of only 80kb (no diference in the color depth i use). I have tryed the same program in the windows mobile 5 emulator with the same error code. When i use "pda load bmp.vi" to load a .bmp, everything is OK. Some hints about this error?
some hints about missing dll are provided here
http://forums.ni.com/ni/board/message?board.id=170&message.id=185995&query.id=129565#M185995 -> can that be my problem? but then, why same error in the emulator?
Aditionally, if .gif or .jpg have to be "flatened" to pixmap for opeation inside my VI , is there any difference (in terms of speed and memory allocation) in loading .gif .jpg or .bmp? i have to operate with the raw pixmap data in "real time", and flatened .bmp images (320x220) do not load and update fast enough... any advice for that?

Michiel
acording to the info provided
LabVIEW 8.6 Mobile Module
The
LabVIEW 8.6 Mobile Module includes the necessary Microsoft tools. The
Mobile Module installs ARM Pocket PC and Windows Mobile targets. You
only need to download and install the following additional Microsoft
tools (linked below) if you need x86 emulator targets:
Microsoft eMbedded Visual C++ 4.0
Microsoft eMbedded Visual C++ SP 4 or later
SDK for Windows Mobile 2003-based Pocket PCs
Note: If you are upgrading from version 8.0 or later of the PDA Module, you probably already have the additional tools.
Since
i have an ARM pocket PC, i understand from the above that no extra
software is needed. Anyhow, i will try to install the recomended tools.
About the VI, well, basically not even the library examples work in my
pocket PC, so, you may try those to see if they work on your devices. I
am afraid that the pocket PC i got (it is actually a PNA and not a PDA)
has a reduced version of WINDOWS CE 5.0 installed and that can be the
reason for the error...

Load image file into a LONG RAW column via SQL*Loader

Does anyone know how to load a image file into a LONG RAW column via SQL*Loader?
Thanks
-Hsing-Hua-

Are you trying to import the image on the client into Oracle lite, or from the server end into the main oracle database for download to the client?
On our system images are loaded into the the oracle lite database (10g R1 at the moment) on the client (DELL X50 PDA's) into a BLOB (Not LONG RAW) column using Java (relatively standard functionality in Java) as this is what our application software is written in.
From the server end, we do not at the moment load images as such, but we do load the application software into the database for deployment of new versions to the clients (the DMC/DMS updates we have found very unreliable), and the technique should be the same for images. Again the file is imported into a BLOB column.
NOTE a column defined as BLOB on the main Oracle database appears as a LONG VARBINARY on the client Oracle lite database, but the synchronisation process handles the conversion with no problem.
To import into a BLOB column on the server try the following
1) you will need to create a DIRECTORY (CREATE DIRECTORY command) within the database, pointing at a directory on the database server (or accessible from it). This is needed for the file location.
CREATE OR REPLACE DIRECTORY PDA_FILE_UPLOAD AS '/pdaapps/jar/'
NOTE create directory needs to be run as SYSTEM
2) define your table to hold the image and other data. Our tables is
SQL> desc pda_applications
Name Null? Type
ID NOT NULL NUMBER(12)
PDAAT_CODE NOT NULL VARCHAR2(10)
VERSION NOT NULL NUMBER(5,2)
PART_NO NOT NULL NUMBER(3)
FILE_OBJECT BLOB
DEPLOY_APPLICATION_YN NOT NULL VARCHAR2(1)
3) copy the image (or in our case a .jar file) to the database server directory specified in step 1
4) the actual import is done using a DBMB_LOB procedure

PSE10 and PSE11 changing original date of image file on loading file to editor.

There seem to be a problem with PSE10 and PSE11 on my computer when loading image files digitized on my film scanner. When loaded into the editor the image file immediate takes today’s date and time, and thus changes place on the timeline. However, sometimes the original image file date remains intact, for no obvious reason. I find this very frustrating.
My setup is an HP computer running Windows7 Ultimate 64 bit, with i7 processor and 12GB memory. My film scanner is a Minolta Dimage Elite II working with a Windows XP-based computer, and data are transferred using memory stick.
Is there anybody out there able to advise me on what to do about the problem?
It might be mentioned that I have made tests with a fixed set of image files on several computers running WindowsXP 32 bit, and several versions of PSE , including PSE10, without seeing this problem.

If you have had a look at your other post,
Why does PSE10 change my file date to today?
you may be able to spot what can have triggered the updating of the catalog. There are too many date types in the exif, some of them are misleading. What is really interesting for a scan? For me (familiy history, genealogy) it's the supposed 'Date taken' or 'CreateDate' to display file chronogically. The file date in the OS is useful for backups.
It's possible that the date digitized has some meaning for you.
If you want to compare the different dates shown by John R Ellis in the Organizer database with those you see in an exif browser (or the properties in the editor, or the information panel in the organizer), you have to note that the 5 types of dates stored in the catalog database are;
-pse:FileDate
-Pse:FileDateOriginal
-xmp:CreateDate
-pse:TagDate
-pse:LastOrganizerModifiedTime
What's important to troubleshoot your problems is to find what operation triggers the updating of the catalog from the files or vice versa.
That can be: Update thumbnail, Write Metadata to files or...

Can load image from file using LabVIEW and display on IMAQ graph?

I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?
Thanks!

Hey werwr,
In response to: "I dont have IMAQ Vision for LabVIEW on my computer. Is it possible to load image file and display on an IMAQ graph?"
As of right now, in order to read an image from file, you actually do need the IMAQ Vision software. The IMAQ driver without the Vision VI's will allow you to collect images from a framegrabber, and it will allow you to save those images to file. But the function that allows you to read an image from file does require the Vision VI's. Once you have the VI to read images from a file, you will be able to display the image on an IMAQ "Graph" or otherwise known as an Image Display.
I hope this helps. Please let me know if you have any further questions.
Thanks,

Using Power Query to import image files for Power View

I am trying to use Power Query to import image data from a SQL Azure database for use in Power View. I've selected both the source image table and the ?images table in the workbook query. The files seem to load as binary data in the Power
Query editor but when loaded to the data model with Power Pivot, the field becomes "text" type rather than binary. Does anyone know the procedure to use PowerQuery to load image files into PowerPivot?

Hi,
We currently do not support loading binary data from Power Query into the Power Pivot data model. This is something we'd like to address soon. For now, you will need to use the Power Pivot import capabilities if you want to achieve this.
Sorry about the inconvenience - we will try to enable this feature over the coming months.

Referencing loaded images in APEX

Hi all:
Up until this point, I have used the same method of getting images to be recognized by an Apex
installation. That specifically has been through loading images into a physical directory on the
machine where APEX was installed. This was made available to me by the DBA that installed APEX.
This is Application Express 2.2.0.00.32 running on AIX Unix.
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
This arrangement worked. I was able to reference any image loaded to that directory using
"/i/[image].gif". "/i/" was set as my pseudo directory by default on Apex.
Over time, I developed an application that is now ready to deploy in like environments and I have
never had a problem with viewing graphics.
For the purposes of demoing to a specific customer, I was asked to deploy this to a different environment
temporarily, I was given the option of loading my application to a Windows XP environment running
Oracle XE and Application Express 2.1.0.00.39.
Since there was no physical directory that I could locate for images, it seemed to me that my only
option was to load my images using the wizard for loading image file components (which I understand
means using XDB)...
I was not been able to get this to work. I went back to my AIX Unix/Oracle 10g installation and attempted
to do the same (load images as a file component and reference them). To my surprise it didn't work there
either.
These are the steps I took in attempting this:
1.) Within my application definition, go to "Shared components"
2.) Under the Files section, I click on "images"
3.) Click on the button labeled "Create"
4.) The page "Create Image" appears. I click on the "Browse" button and I pick the image from my local file system.
5.) I leave the drop-down list as is (reading "No Application Associated")
6.) I click on the "Upload" button.
I then go back to my application under "Edit Attributes" and reference the file as /i/[file].gif
I find that the images do not show up. On IE, all I get is the standard red "X" indicating that
an image file failed to load.
I can't help thinking that I'm missing an obvious step. Let me know if there's any other info I should
provide.
Thanks

HI,
To reference images loaded through shared components use:
#WORKSPACE_IMAGES#filename.gif (when you set it to No Application Associated)
or
#APP_IMAGES#filename.gif (when you associate it with a specific application)

Error: BFILE not exists when i insert an image file(.jpg)

Hi,
i have created a directory
called sampl_dir as '/home/oracle/files'
i have an image file(.gif) and 3 pdf filesin the
directory.
i insert 4 rows in to the table using BFILE for all
the 4 LOB.
i get output in TOAD, where for all the pdf files, but when i select * from table.
for all the pdf files output says 'EXISTS' but for the image(.gif) FILE, the
output says 'NOEXIST'
I tried putting all the files in different locations
and tried giving different file owner, and group owner
but whatever permissions i set or wherever i put the
files, the output always says 'EXISTS' for pdf files
but not for gif file.
so i was thinking there is something got to do with
the format of the image file, or is there someother
way to select image from the table. i mean i thought
"select * from table" may be does not work for images
but it does work for text, pdf documents. am i right?
how do i solve this?
Thanks,
Philip.

Hi Kamal,
this was the plsql code i used to load image file and read the length. and it did not work
DBMS_LOB.LOADBLOBFROMFILE(v_dest_blob, v_source_locator1, DBMS_LOB.LOBMAXSIZE, v_dest_offset, v_source_offset);
DBMS_OUTPUT.PUT_LINE('Size of BLOB post-load: '||(v_dest_offset -1));
but now i modified the above as the following one shown below and it worked, can u tell what was the problem with the above code
DBMS_LOB.LOADBLOBFROMFILE(v_dest_blob, v_source_locator1, DBMS_LOB.LOBMAXSIZE, v_dest_offset, v_source_offset);
DBMS_OUTPUT.PUT_LINE('SIZE OF IMAGE FILE: ' ||DBMS_LOB.GETLENGTH(v_dest_blob));
i did the select query as u told for selecting the length and now it works and i am able to see the output length as 27342.
Okay Kamal, now is there a way that i can view a pdf file and image file after i select them from the table. i mean when i do a select query on the blob column, i only see result as "(HUGEBLOB)". BUT instead can i see whether what is the blob that is stored like whether it is a pdf or image and what is the name.
how can i actually see the blob file names etc.
Thanks,
Philip.
