Webutil - Read Image?

1.While reading image into image item of my canvas
if the image size larger then my image item size
i want it to be scroll both horizontally and vertically.
Is that possible.?
2.I want to give zoom in/out functionality to that image item.
How?
3.Also i want to restrict the user from select file type
other than gif,tif,jpg,jpeg,bmp etc...???

Dear Faheem;
For ur questions No. 1 & 2 if you open the property palette for the image item you search for the categeory[b] faunctional there is a property called[b] Show palette assign it to YES then if you run ur form you will get a control palette for zooming or moving the image.
For Quest. 3 I think you have to use it by coding like this code :
photo_filename := tiff_image_dir||LOWER(:emp.userid)||'.tif';
** For example 'photo_filename' might look like:
** /usr/staff/photos/jgetty.tif
** Now, read in the appropriate image.
READ_IMAGE_FILE(photo_filename, 'TIFF', 'emp.emp_photo');
Hope it help

I am facing a Problem with reading images from database

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...
string connect = "datasource = localhost; port = 3306; username = root; password = ;";
MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
MySqlDataReader reader;
try
conn.Open(); // Opening Connection
reader = sda.ExecuteReader(); // Executing my Query..
while (reader.Read())
byte[] imgg = (byte[])(reader["Picture"]);
if (imgg == null)
pc1.Image = null;
else
MemoryStream mstream = new MemoryStream(imgg);
pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches. I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data. The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data. The solution usually is to use UTF8 encoding instead of the default ascii encoding.
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

Problems with my Acrobat IX reading images

I have just started having problems with my Acrobat IX reading images. I have now noticed that when I open up a PDF, the images are now blacked out with a black box. These are all documents that I have been able to read just fine in the past. I have done some research online and have found others who are having the same problem but I cannot find a solution. Some solutions I have found are to make sure on the printer settings that it reads large images which I have done and that it prints in color which I have also done. When I print out the document, it prints just fine, I just cannot read it on the screen.
Please any help would be greatly appreciated.

Thank you so much for taking the time to respond but nope. unfortunately I have tried that a few times, both clicking and unclicking the view large images with no luck. Since I have Acrobat IX Adobe wont help me. Any other suggestions? Should I just uninstall and reinstall this program?? When I Google this problem it appears that a lot of people are having this problem.

Can't read image file

Dears,
I was having forms version 10.1.2.0.2 and I was using webutil to upload an image and to download it. My problem is sometimes the image files are uploaded and sometimes not => I got "Can't read image file D:\...\image.jpg"
I upgraded to forms 10.1.2.3 and the problem persists.
I'm seeing that the picture resides in the workspace environment and not uploaded to the database.
I'm not limiting the size of the pic in the frmweb.cfg file, instead this limitation occurs on form level.
Hint. If you save this picture in "photoshop" tool, than you can upload the same picture without any problem.
Any suggested help will be appreciated.
Best Regards,
Joe Farah

Yes dear, this is the way that we can follow in order to get rid of this problem. Actually we have to mention to all users of my system to save the image file in this tool. But, it's somehow cumbersome for them as they might not have any of the mentioned imaging tool on their systems, isn't it ?
But isn't there any way to fix this problem ? Or shall I go by using PJC/Java Beans ? We have to find an effective way.. :)
Thanks,
Joe

Image problem in java

I am experiancing a problem in reading an Image datatype from SQLServer7.0 using java. The Image is created using MSAccess application and I am trying to read the same Image using Java. I am using InputStream to read Image and writing bytes to another file(a.gif). When I opened the image it says invalid format. Below is my code. Help me....
          String s = "select * from Image where IMSCANUSERID='A'";
          java.sql.ResultSet rs = conn.createStatement().executeQuery(s);

what format image is it exactly. you say you are saving it as a gif but you seems to be saving at as a tif. these are not the same.

then save it as that type.

Hi, I have faced a similar problem and solved it using the morena api http://www.gnome.eu/Twain/examples/studio.html
Problem is the scanner works fine with TWAIN, but with SANE, it is totally failing. There is a permanent connection refusal form the scanner ip whenever

Read Image File Error

When I read image with Read_Image_File procedure i got an error in specified files 'FRM-47100 can not read image c:\abc.jpg'
i think it is on high resolution please promply resolve it. its very urgent
best regards
R E H AN M I R Z A

Hello,
Found this on Metalink:
Problem Description
You are trying to use READ_IMAGE_FILE in forms to read a JPG image,
but you receive the following error:
FRM-47100: Cannot read image file <file name>
You checked the following:
o You are able to open the image file from Netscape or Internet Explorer and
see your image correctly.
o You are also sure that the file exists under the location mentioned in the
first parameter to READ_IMAGE_FILE built-in.
o You tried other JPG files that are located in the demo directory of the
Developer home and you can see the image loaded in the image item.
Solution Description
There are many JPEG formats. The only JPEG format supported in Forms is the
JPEG File Interchange Format (JFIF) which is the baseline sequential DCT JPEG.
Progressive JPEG (as well as Lossless JPEG and Hierarchical JPEG),
are not currently supported.
Possibly your image file is stored using one of the non-supported formats.
As a workaround, you can convert progressive JPEG format to and from baseline
JPEG. There is a free set of programs provided by the Independent JPEG Group
that allows this.
The Independent JPEG Group home page is: http://www.ijg.org/

Read-image-file show jpeg photo cause error

I use read-image-file to show a jpeg photo (edited by ACDSEE) cause frm-47100. I know that Oracle may not support the Jpeg format of ACDSee. But, anyone know how to solve this problem. (I have to keep using ACDSee)

If you remove the metadata from a JPEG it should usually do the trick. I don't know how to do that in ACDSee, though.

Image problem in V4.0

Hi,
Previously I had lots of problems with showing a BLOB image from a table
in a report using the apex_util.get_blob_file_src function.
Varad put me right on several ocassions: see the thread at
Confusion with get_blob_file_src
Eventually everything went well, and I got my images of a specific size on the screen.
In the last month or two, the host database that I rent went up from version ten to version
eleven, and the apex version changed too from 3.2.1 to some version of 4.
I've only now discovered that the images don't display any more. I've re-read the thread
mentioned above but can see no deviation from Varad's sterling advice. It still doesn't work,
so my current guess is that something has changed when Apex went to its new version.
Can anyone point me in the right direction regarding Image problems in version 4 ?
I guess I'm not the first to experience such issues, and a checklist of things to try would
be most welcome.
I've done a View->Source on the page that doesn't work, and the issue with a missing value
for the "d=" parameter on the apex_util.get_blob_file seems to have recurred:
src="apex_util.get_blob_file?a=130&s=1718106956127950&p=13&d=&i=25615931827270369&p_pk1=5&p_pk2=&p_ck=947078FC54BB5126E7E0D19F8A24C416"
Suggestions welcomed please; thankyou in advance.
Mungo

Hi Folks,
I've found a solution to my "image" problem that caused this thread, hence the decent thing is to
post it here.
I read various other threads and stumbled across:
PDF viewing with apex_util.get_blob_file_src not working with 4.0
PDF viewing with apex_util.get_blob_file_src not working with 4.0 &# 4404695
That thread mentioned the requirement for an "Automated Row FETCH" process as well as having
an "Automated Row PROCESSING" process too.
I had the latter, but didn't have the former, so throwing caution to the wind I tried adding a dummy
Automated Row Fetch process and the damn thing worked!
Haven't got a clue why on earth either of these are requirements on a page that is selecting data
from the database - I don't understand where such processes are called in the big scheme of things.
That's just me baiting some kind soul to spell out the fundamentals for this idiot... please?
Happy to be corrected on any points.
Regards until the next crisis...
Mungo :-)
P.S. How come there is no reasonable way to get the URL of a single post in a thread - I'd like to give
reference to the single post that helped me, but all I seem to be able to get is the whole blooming thread.
Suggestions?

Photosmart D110 All-In-One Printer - Shadow image problem

I have been having a problem with this printer, ever since we purchased it about 2 months ago, where it will print a shadow image of text or pictures on some documets but not others. It is specific and consistent in that it will print this shadow image on some documents every time and on other documents none of the time. I have a PC and a Mac and it doesn't matter which computer I use, only which document. Sometimes it is only a part of a document, like the computer generated part of an email where it says " this person at this time on this date wrote.." but the other text will be fine. It happens on some coloring pages but not others. I spent 2 hours on the support line yesterday; it's still doing it. She had me unplug it, take off the printer software and reinstall it, update software (on my Mac) and it did not fix it. Any ideas on what may be causing this & how to fix it? I like the printer but am about to return it because of this problem. The printer we had been using was an HP C4280 and did not have this problem. I'd like to keep the printer if I can fix this problem.

I'm having the same shadow imaging problem on my Deskjet F4580, so if anyone knows how to correct it please post.. I've reinstalled/updated the driver, disabled advanced features, and deslected "Enable HP Real Life Technoliges".

Persistent Image problem

Okay, I just had the screen on this iMac replaced because of this problem with a dark line at the top of the screen. The screen has been replaced, and the dark line isn't there anymore. However, I am now having persistent image problems. This is noticeable when I use the Aurora desktop. If I have a window open (e.g. Safari) for a long enough time, and then I X out of it, I will see a shadow/ghost of it. It's most noticeable with a dark background. However, I DID change some of the settings in "Appearance," so I wonder if that might have done it. But I can't see a way to change everything back to default. Do you know if there's a way?

Hi again - a couple of ideas:
If you haven't printed the images or a while, it could be that you prepared them under a previous version of the Aperture raw and they've since been reprocessed, resulting in a slightly different look
I had an occasion about 12 months ago when an update to the Epson printer drivers caused me to have to go back and change my print setups in Aperture, due to new colour interpretations. Don't know why, but it happened... maybe your settings have changed since last printing?
Could be that you did or didn't have the appropriate soft-proofing turned on - are you using this feature?

Strange short-term persistent image problem

Hello,
I'm well aware of the typical image persistence problem, where an image can stay "burned in" after the monitor displays the same thing for hours on end.
I have a much shorter-term persistent image problem. Let's say I open a web-page, leave it open for 10 seconds and then open a new window in Safari (thus getting a pure white page). Well when that happens, the previous web-page is still shadowed on the new white.
30 seconds later it has faded, but then the same thing will happen again with anything else that's displayed.
Any ideas?
thanks
Loa

Huh, now I'm really stumped. The cyan border is also present in FCE once I render, but it doesn't seem to happen for each instance when the paper image is used. Did you import the paper image as a .gif or something else? And did you add any filters to it? Did you also add any effects? The only I'm using with the paper image is the page peel and I have not tried any other effects to see if the cyan effect comes up.
I've put a screen capture of my FCE project showing the cyan border present in the canvas as my movie is playing. Its on my idisk as FCE movie problem.tiff

Read Image XMP Metadata

Hi All,
Hope I'm not spamming this thread to your mailbox as I felt this question asked in unrelated forum.
Question: Can we read image meta data from Flex ?
I tried it with xmp core library and passed a jpeg file to xmpMeta object :
private function getImageMetadata(jpeg:File):void
                              var meta:XMPMeta = new XMPMeta(jpeg);
                              var packet:XML = meta.serializeToXML();
                              var photoshop:Namespace = XMPConst.photoshop;
                              var value:String = meta.photoshop::AuthorsPosition;
                                trace(value); // returns null, not sure why
Can any one help me to get the image metadata.
Thanks in advance

How Read image from slingRequest

Hi,
We have a user input form which contains input file (image) selection. When user submits the form, we want to read the file selected by user and store it as base 64 encoded data. We have following code to do the same. This code gets executed when the form is submitted.
//Read image data from slingRequest
String userImage1 = slingRequest.getParameter("userImage1");
//Apply base 64 encoding on the data received in slingRequest
String encodedUserFile = "";
byte[] userFileBytes = userImage1.getBytes();
encodedUserFile = Base64.encodeBase64String(userFileBytes);
These statements are not throwing any error. But, when I try to apply base 64 decoding on the contents available in 'encodedUserFile', its' not the image user uploaded. There seems to be some problem, which I am not able to figure out. Can someone please help me with this?

Hi,
You need to use the Sling RequestParameter interface to get an uploaded file.
See:
http://sling.apache.org/site/request-parameters.html
http://sling.apache.org/apidocs/sling6/org/apache/sling/api/request/RequestParameter.html
