READ_IMAGE_FILE

The simplest way to load image in an image item on forms is on WHEN-BUTTON-PRESSED trigger:
read_image_file('/schite/test4.jpg', 'ANY', 'bl_Ctrl.image_item1');
where 'schite/test4.jpg' is an existing file on my Application Server 10g , a file with appropriate permissions. The form contains only one button and one image item, and the only pl/sql code is read_image_file above;
If the file exists in the Application Server path specified, form become unresponsive (hourglass, as is executing a long code). The code is not working for any file path existing in Application Server.
When i tested the code with a wrong path (ex: '/schite/nonexistingfile') the forms respond correct with message: FRM-47109 'Cannot locate file /schite/nonexistingfile'. If the path is correct form is showing the hourglass and becoming unresponsive.
It's a bug? It's something wrong with my application server? (evrething else is working ok).

The "imageNamed" method is only for images in specific locations. If you need to create an image from an arbitrary location, use "initWithContentsOfFile".
Also, development questions like this should probably go in the Developer forum: https://discussions.apple.com/community/developer_forums

Problem in using client_image.read_image_file

Hi all
I want to load a picture file into a forms item at Develeoper Forms 10g Rel.2 with the following procedure, but it doesnt work and i also get no error.
PROCEDURE import_image
IS
vFileName VARCHAR2(512);
BEGIN
-- Transfer Picture from File Directory to Forms Item.
GO_BLOCK('FOTO');
SET_BLOCK_PROPERTY(FIND_BLOCK('FOTO'), DEFAULT_WHERE,

SET_BLOCK_PROPERTY(FIND_BLOCK('FOTO'), INSERT_ALLOWED,
PROPERTY_TRUE);
SET_BLOCK_PROPERTY(FIND_BLOCK('FOTO'), UPDATE_ALLOWED,

SET_ITEM_PROPERTY(FIND_ITEM('FOTO.FOTO'), UPDATE_ALLOWED,
PROPERTY_TRUE);
BEGIN
vFileName := NULL;
vFileName := webutil_file.file_selection_dialog('C:\Temp\', '*',

END;
IF vFileName IS NOT NULL THEN
client_image.read_image_file(vFileName, 'BMP', FIND_ITEM('FOTO.FOTO'));
client_host('cmd DEL ' || vFileName);
END IF;
END import_image;
I think the WebUtil 1.0.6 works properly because the 'webutil_file.file_selection_dialog' (see above) works fine.
Now can somebody give me a tip?
Best regards
Martin

I found the problem :-)
When i change the following parameter in the file webutil.cfg it works fine.
transfer.appsrv.enabled=TRUE (old: FALSE)

Why READ_IMAGE_FILE is not working in Linux Appln Server?

Hello!
I have a form with a new_form_instance Trigger I wrote the read_image_file trigger to read a GIF file in an image item.It works fine on windows XP(development machine).I copied the GIF file to the same location where my fmx files are there in Linux application server.I copied and compilied my fmb file in linux application server.No compilation error is there.But when I run form from Linux the form hangs and my read_image_file command is at new form instance Trigger.I have checked the case sensitivity of the file and the permission etc in Linux.In windows Development machine the form runs successfully.What could be the problem.Please help.......

Hi
Incase if you find any server related error like "FRM-92101" happening on READ_IMAGE_FILE functionality, try to change the image item format from TIFF to BMP/JFIF.
Otherwise if you changed any Jinitiator or JRE Version, sign again for all the JAR Files and restart your server.

Client_Image.READ_IMAGE_FILE problems

Hi, I have search all over OTN and the web and can't seem to find a solution to my problem. Im using Forms 10gR2, and am trying to display a TIFF image in a form. I am not getting any errors, its just not displaying the image at all.
I have the images stored in C:\temp\0-GRAPHICS\. I have looked at the webutil.cfg file and updated it with the following:
#NOTE: By default the file transfer is disabled as a security measure
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
transfer.appsrv.workAreaRoot=c:\TEMP
transfer.appsrv.accessControl=TRUE
#List transfer.appsrv.read.<n> directories
transfer.appsrv.read.1=c:\temp
transfer.appsrv.read.2=c:\
transfer.appsrv.read.3=c:\DevSuite10_1_2
#List transfer.appsrv.write.<n> directories
transfer.appsrv.write.1=c:\temp
transfer.appsrv.write.2=c:\
transfer.appsrv.write.3=c:\DevSuite10_1_2
When I run the code, i get no error, it seems to work, just no picture displayed. Here is my code
When-Button-Pressed trigger:
DECLARE
tiff_image_dir VARCHAR2(80) := 'C:\temp\0-GRAPHICS\';

Am i not initializing the tiff_image_dir properly? Thanks for any help.

Without actually being able to test your form, my only remaining guess is that the version you are using has a defect. Since you did not mention exactly which version you are using, I will guess and say that you are using an unpatched version. Please ensure that you are using Forms 10.1.2.3. If you are not using this patch version, I recommend you download and install it. You must have a current MyOracleSupport (and Support) account to do so. The patch ID number is: 5983622
Also, since version 10 is no longer entitled to Premiere Support, it might be a good time to consider upgrading to the latest release, 11.1.2.2
http://www.oracle.com/technetwork/developer-tools/forms/downloads
Installing WebLogic Server 10.3.6 is a prerequisite to installing Forms/Reports 11.1.2.2, so be sure to download and install it first. Be sure to review the product documentation before installing any software.

Hi,
Copy your all image files into directory where your
HTML files directory ( Oracle search these image files in
local directory ( directory of HTML file ))

WebUtil - Read_Image_File Issue

In the process of converting from 6.0 to 9i certain forms require WebUtil which has been installed successfully. However, when using the procedure 'Client_Image.Read_Image_File' I have discovered a 'problem'.
After the .bmp files have been read and processed I need to 'rename' and 'move' these files to another directory via Host commands. But, there seems to be a sharing violation where the source or destination may be in use. The only way I have found to 'release' the files is to close the Oracle9iAS Forms Services. Since this is unacceptable, is there a command which I could use to close/release the open .bmp files ?!
Any help/suggestions would be greatly appreciated.
Steve D.

Hello,
I am facing similar problem while trying to delete downloaded/stored temporary word documents. It is possible to delete the files manually only after the browser is closed. Is there any work around for deleting these temporarily downloaded/used files no longer in use from the application without closing the browser?
When we have to leave downloaded copies of docs from database on to local end users machines it puts us in a very bad shape.
Thanks.

READ_IMAGE_FILE question

Hi,
I am wandering if anyone is aware of a bug or else with READ_IMAGE_FILE within Forms 6i, its just that I have been successfully storing away images to the DB by the hundreds without any problems but have just a handfull of cases that refuse, infact as soon as I capture the image the application just hangs forcing a CTRL+ALT+DEL.
Please throw any suggestions at me.
Cheers

Hi Grant,
The equipment used to capture all images is exactly the same and all is hard coded within the form. I have included the code line if it helps.
Read_Image_File(:GLOBAL.image_filename,'ANY','table_images.image');
(Have I interpreted your comments correctly ?)

READ_IMAGE_FILE built in on Forms 6i

Hi all,
I have learned there was a bug in Forms 6i (Win2000) using READ_IMAGE_FILE built-in. It was not possible to load JPG images without converting them in JFIF.
Is this bug fixed? And is it a way to use an URL instead of a filesystem path to locate the image wanted?
Thanks, Marco.

Marco,
If you can provide me with a bug number, then I can look it up and tell you if its fixed. Actually the read_image_from_file is supposed to read an image from the filesystem. Read image from a URL is not supported in Forms.

Read_image_file issue resizing when format= url

Hi,
I'm migrating from 6i
I have some images to display, let's say logos and such, which in c/s I loaded with read_image_file into an image_item.
Now, in the 11g version, I've put all that logos in a jar, as the read_image_file is now relative to the weblogic server, not the forms client.
So, I'm changing this code:
Read_Image_File ('H:\mypath\logos\mylogo.tif', 'TIFF', 'block.image_item1');
by this:
synchronize; -- now this is neccesary
Read_image_file (file_name => 'aenor.gif', file_type => 'url', item_name => 'BLOQUE.LOGO1');
after converting my logo to gif and putting it inside a jar (which I load properly in formsweb.cfg).
The problem:
I see the image, but,
If I set sizing style property to adjust, the image appears very tiny inside the image_item .
If I set that property to crop, the image crops as expected (the gif is bigger than the item).
Any hint or workaround (other than resizing the gif)?

The URL option does not support scaling.
Consider what Francois suggested in this other post: Display an static image

READ_IMAGE_FILE jpg format

I'm not able to open a jpg image file with the READ_IMAGE_FILE command.
I try
READ_IMAGE_FILE('C:\TMP.JPG','JPG','BLOCK.ITEM')
it make the FRM-47100 error.
The "block.item" is an image item, but its "image format property"
don't include the jpg format.
Any suggestion?
How can I open jpg image files?
Thanks!

I found this thread from 2002 in search and today, 2011, i have the same problem.
There is not any patch to make forms work with all jpg?
My design team upgraded to Photoshop CS5 and it no longer has support to generate a compatible jpeg.
I had to let a computer with photoshop cs3 just for it.
If ther is no way to make forms work with enchanced jpeg, there is a way to make it work with PNG?
Thanks.

Read_image_file command does works on Linux application server

For me, attempting the following:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'GIF', 'IMAGE7');
gives this error:
  FRM-47109: Cannot locate image file bullet_ball_glass_blue.gif
Changing my command to:
  READ_IMAGE_FILE('bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
loads the image successfully.
If you truly are not getting an error message (mine appears in the status bar), then perhaps the file is being found, but the image format is not recognized or otherwise incompatible. Test this by loading one of the the images that load successfully into your iconic buttons. If that image loads successfully into your image item, fix the problem GIF image. (Recreate or open & resave with a graphics program, etc.)
If this does not appear to be the problem, the only things I can think of are for you to confirm that, in formsweb.cfg:
  1. The archive_jini entry includes your image JAR
  2. If imageBase=DocumentBase, change to imageBase=codebase
The second change may temporarily break your iconic buttons. This can be fixed by updating the buttons' Iconic Filename properties specifying only relative paths found within the JAR. Since my image is stored in the root of my JAR, no path need be specified. Had I placed my image in a subdirectory within my JAR, named images, my call would have to be changed to the following:
  READ_IMAGE_FILE('images/bullet_ball_glass_blue.gif', 'URL', 'IMAGE7');
I'm not sure whether any of these suggestions will help, but since I had no problems, I suspect it's simply a matter of differing configurations. The two items that I listed are the only two likely differences I could think of.

READ_IMAGE_FILE problem?

Using Forms 6.0.8.22.1 and Oracle 10.2.0.2 our form calls READ_IMAGE_FILE() to display TIFF files. It works for most files except a couple of files. Without an error message, the form suddenly shuts down as soon as it displays images. These images that shuts down the form can be displayed with other software and TIFF files are not corrupted.
Although I found the document describing that in patch 9 the problems with TIFF were fixed, I wonder if my problem is related to these problems. Or is there any size limit on files? Any comments would be appreciated.
Sarah

You may want to consider this.... I havent used it, but wish I had something like this in the past.
http://fdegrelle.over-blog.com/article-4018412.html
My experience is that forms mangles on insert and/or decides on a daily basis what it wants to display even for supported formats. I do know that not all tiff formats are supported. I cannot seem to find a current link to whats supported though... I know its out there..
Heres an old revised metalink note 1009546.6 as of 2005 that says tiff 4,5, & 6 are supported. This may be old data though. More may be supported now.
Is it possible that these problem tiffs were created with different software than the displayable tiffs? The problem software may be saving the tiffs in a different tiff format than what a forms image item likes to display? Could you download one of the problem tiffs, resave it to the PC with a image program that is known to generate a tiff format that Forms likes. Then upload the image again via something like TOAD, and then see what forms does with it on display? Its probably a format thing just for those few tiffs...
for example...
If I recall correctly, could be wrong, that a tiff can have layers. If you read_image_file a tiff with layers and then save it, the saved image will not have layers. Pretty sure. This kind of mangling makes me wish I knew of this java solution above beforehand.
