How to display large image using JAI

dear all,
could anyone tell me how do i display an image which is around
5000x5000 pixels in JAI. I try to use BufferImage to store the image
but JVM throws" out of memory " error while program is running.
thanx a lot!

just a rough estimate, but a 5000x5000 image would require at least 24MB assuming each byte is one pixal, I believe they are 4 bytes per pixel in RBGA format. (5000*5000) = 25,000,000 pixals /1024/1024 = 23.8MB for 1 byte pixals, *4 for 4 byte = 95.3MB. I'm pretty sure that this is how it stores it. Maybe I'm wrong but it certainly explains the situation. assuming you have at least 256MB ramm, run java with -Xmx200M and see what happens.
java -Xmx200M app
or if you have more ramm, like 512, use 450 or 500.

Hi,
do you want to work with the image or do you only want to show it into a container?
you can increment the JVM Memory available space. Or you can split the image into smaller BufferedImage, draw it and call the gc...

How to display an image using MIDP on Palm?

How can I display an image using MIDP on Palm? The following code works on the Siemens SL45i, but not on Palm:
public class Test extends List
Image image = Image.createImage("/images/test.png");
append("item 1", image);

Have found the exact same problem when trying to display an image (other then the default (null)) in a list, on a Palm.
The image displays correctly on a form, but when set on an element in the list, it does not display. (mind you this is in both emulator mode and on the real device)
It does not seem to be related to size of the image.
The Sun documetation states, that you should not rely on it been displayed (obviously it's an implementation issue with the Palm, and other devices I have not tried)
But like to hear definitively from Sun though!

How to display dynamic images using Struts

I am storing the image name in bean. I want to use the <html:img> tag to display my images. How can i do that using struts.
Something or sort..
<html:img src=bean:write name="pageEntry" property="pageImg"/>
Thank You

* In your web.xml file, add the struts-html-el.tld definition from the struts\contrib\struts-el\lib directory
* Add this tag library to your JSP page; something like:
<%@ taglib uri="WEB-INF/struts-html-el.tld" prefix="html-el" %>* Refer to the following example:
<html-el:img src="${pageEntry.pagePic}" />* This assumes that pageEntry is a Bean, and pagePic is a bean variable accessed by the getPagePic() method.

How to display local image using JSP in Struts

I am trying to display image from my local disk (eg. file://C:/Documents%20and%20Settings/varshaaz/Desktop/DSC_6172.jpg). When I execute my JSP(http://localhost:8080/sharedgreeting/test.jsp) , Image doesn't display instead I see cross icon. Though properties of that icon shows correct file path.
Content of my JSP is :
<html>
<body>
<img src="file://C:/Documents%20and%20Settings/varshaaz/Desktop/DSC_6172.jpg"/>
</body>
</html>

Store your images in a folder (I've called mine gfx) under the WebContent folder of the WAR and make a call to that folder using a relative link rather than one on your hard disk, if it is a web project.
WebContent
--- gfx
--- stylesheets
--- etc...
--- createMeetingOrSomething.jsp
Then the link in the above jsp will be:
<img src="gfx/someJPEG.jpg" height="50">Illu

How to display iconic images using forms 9i

Hi,
i had created a simple push button ,and made its properties iconic=yes and icon file name =c:\temp\save
i had copied the save.GIF file in the c:\temp path
also i had made necessary changes in the orion.web file
and registry.dat
actually i had the metalink document 203846.1 and followed all the step written in that doc.
but then also during run time i am not able to see the icons.
Can you give me a sample code having only one push button
and all the changes in different files to make the icons appear in web.
I had tried all the steps so pl give me the sample step by step code.
Thanks ,
Kumar Iyer

Hi Kumar,
I think if you follow the oracle note 203846.1 more or less it should be fine. I took a little exception on step 7 which requires modifying the registry.dat file.
I ignored the step 7, try this in forms builder for button property
1) icon filename=save
2) create jar file for icons under c:\temp directory, using the command
C:\Temp>jar -cvf icons.jar *.gif
please note that file save.GIF should be save.gif since java is case sensitive.
3) modify the following entries in file <9iDS_HOME>\forms90\server\formsweb.cfg
archive_jini=f90all_jinit.jar,/forms90/icons/icons.jar
imageBase=codebase
so this should help in your test form to display icon at runtime.

How to display a image in webdynpro view using a bytearry

Hi,
byte[] img = wdContext.nodeYywwwdata_Import_Input().nodeOutput().nodeOutMime().currentOutMimeElement().getLine();
use this code to create resource and you need to set this value to the context created to display the image suppose in the image UI and set the source property with this attribute:-
IWDResource res=WDResourceFactory.createCachedResource(b,"MyImage",WDWebResourceType.JPG_IMAGE);
IPrivateAppView.IVn_ImageTabElement imageEle=wdContext.createVn_ImageTabElement();
imageEle .setVa_Name(res.toString());
wdContext.nodeVn_ImageTab().addElement(imageEle);
Hope this may help you.

How to display the image which in KM folder using url iview

Hi Friends
How to display the image, which is under KM folder structur using the url iview.
i trying using url iview url as \document\testfolder\abc.jpg as url for the iview.
but its now working .. so please help me how to slove this problem
If is not the correct way then please suggest me best way to achive this.
Thanks
Mukesh

Hi Mukesh,
I think this may work,
1, Create a HTML Layout.
    You can put your image wherever u want with HTML Codes.
    Check this, [Article|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3915a890-0201-0010-4981-ad7b18146f81] & [Help|http://help.sap.com/saphelp_nw04/helpdata/en/cc/00c93e9b2c3d67e10000000a114084/frameset.htm]
    With this, u can use the standard KM commands also.
2, U need to use KM Navigation iView for this rather than KM Doc iView.
3, In the Nav iView, u can use &rndLayoutSet=nameOfUrHTMLLayout to force the view with this new layout.
Regards

Image display - How do I display an image using an absolute path?

How do I display an image using an absolute path in a compiled WebHelp?
Our developers use RH8 map IDs within our in-house applications to display in a model window created using Telerik Rad Window.
Unfortunately images disappear from these model windows because RoboHelp removes absolute links to [inserted] images and changes them to relative in the compiled WebHelp.
How do we overcome this? Is there a solution in RH8?

I have tried again and changed the path in the topic HTML
from : ..\..\HelpTopics\Icon_Search.png
to : \HowDoI\Help_CMS\WebHelp\HelpTopics\Icon_Search.png
I am obviously unable to see it in RH8 as I have removed the relative link so it is "outside" of the project.
This time, on compilation, it has not stripped out the absolute links. The developer was working with me on this last week and we did have any issue in that they did not hold the absolute link. Most odd!
Checking the published help it appears to be working in the application, which is great.
So my apologies for raising the issue but it really did not work last week.

How to dispaly large images?

Hi!
I have a simple problem, hope somebody could help me!
I would like to display images from a LONG RAW type column of an Oracle database (Oracle8i Enterprise Edition Release 8.1.6.0.0) in a BC4J application. I use JDEV 9.0.3.
The wizard generated entity object's attribute type for the image field is raw, i could not find the LONG RAW type in the java types. The maximun size of the raw type is 2000 bytes, so my app can not handle and display large images. How could i solve this problem? Pls help me!
I have read the otn forum tips, but they did not help me :((
Thanx
Bence

You may try mapping your column to BlobDomain!
If that doesn't fit the need, you'd have to create a similar LobDomain (see BlobDomain.java source in bc4jdomorcl.zip) for LongRawDomain so that it uses streamnig apis to fetch data from jdbc rather than using a column-value fetch.

How to Display an Image on my FORM

Good Day!
I would like to ask some help from you guys with my problem on how to display an image on my form. I would like to display my uploaded image on my form but instead of an image, the get_blob_file is showing. By the way, I'm using Apex 4.1
I downloaded the Order Entry Sample Application and followed the Page 6, the Product Details. I even made snapshots of each details from Page Rendering to Page Processing in order not to miss a thing.
At the moment, I was able to upload or store the image on my created Oracle table and also able to retrieve it on the Download Link Text with Content Disposition value of Inline, provided by APEX Settings. If I invoke the Download link beside the file browser, a page with the image will be shown, below is the address:
http://127.0.0.1:8080/apex/apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6&p_content_disposition=inline
However, instead of showing the image on a region, below is the one showing on my Form:
<img src="apex_util.get_blob_file?a=200&s=339877802936975&p=230&d=7107921433296839&i=7107601420296838&p_pk1=54&p_pk2=&p_ck=7D6512D967336C4B94258EEA3CDF1BE6" />
As you can see the parameter values are the same but I know I missed something that's why I'm here :)
I would highly appreciate all the help you can provide and many thanks in advance.
I tried to change gear by making an html region of type PL/SQL (anonymous block) and a procedure but still no image :(
Below are the scripts.

else
htp.p( 'No Image ');
END IF;
htp.p( ' ');
end loop;
end;

INTO l_mime,lob_loc,l_file_name,l_length
FROM wsemployee
WHERE empid = p_image_id;
-- set up HTTP header
-- use an NVL around the mime type and
-- if it is a null set it to application/octect
-- application/octect may launch a download window from windows
owa_util.mime_header( nvl(l_mime,'application/octet'), FALSE );
-- set the size so the browser knows how much to download
htp.p('Content-length: ' || l_length);
-- the filename will be used by the browser if the users does a save as
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(l_file_name,instr(l_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
END my_image_display;

Displaying large images in MIDP 2.0

Hello,
I've been building a little file browser in MIDP 2.0. Now I'd like to add some file opening in, too.
Videos and sound can be played quite easily using the MMAPI.
But images are a tougher case. I haven't found any way to display images using the MMAPI, and loading big images with Image.createImage causes an OutOfMemoryException.
So, does anyone know a trick (extensions are OK too) to display large images with? Naturally downsizing, as in the case of videos, is OK too.
-- Mikko

about image resizing, it is very difficult issue.
I did this code for my company in 2 whole weeks. and sure I can not post it.
pluse this code was only for Jpeg files.
I still can give u some hints,
1- There is open source code I dont remeber its name ,I think it was JPEG Decoder for J2ME try to search for this.
this code is said to be for J2ME, pulshit . when u just instansiate instance from this class u got OutOfMemory Error. but this code still good as concept.
2- Use the previous code to do the decoding while reading, I mean u will have to open stream on ur file then decode the data and resize.
Good Luck

How to display an image, which is stored in a database?

Hi All,
I would like to display an image with Web Dynpro.
I already know how to display an image which is stored in the path src/mimes/Components/...
But does anybody knows, how to display an image which is stored in a database (e.g. MaxDB)as a datatype of binary?
Thanks in advance!
Regards,
Silvia

Hallo John,
yes, you can use the Image UI element.
Further you have to create a String for the URL. Implement like as follows:
IWDCachedWebResource cachedResource = null;
String imgUrl = null;
WDAttributeInfo attInfo = wdContext.getNodeInfo().getAttribute(IPrivateXYView.IXYElement.PIC_DB);
IWDModifiableBinaryType binaryType =
(IWDModifiableBinaryType) attInfo.getModifiableSimpleType();
binaryType.setMimeType(WDWebResourceType.JPG_IMAGE);//Example *.jpg
WDWebResourceType type = binaryType.getMimeType();
byte[] file = wdContext.currentXYElement().getPicDB();
if (file != null)
cachedResource = WDWebResource.getWebResource(file, type);
try
imgUrl = cachedResource.getURL();
catch (WDURLException e)
IWDMessageManager msgMgr = wdComponentAPI.getMessageManager();
msgMgr.reportException(e.getLocalizedMessage(), true);
I hope it will help you.
Regards,
Silvia
