InterMedia Image JPEG

InterMedia Image's JPEG compression allows 5 discrete compression values only - MAXCOMPRATIO, HIGHCOMP, MEDCOMP, LOWCOMP and MAXINTEGRITY. JPEG itself supports compression to any percentage 1 - 100. Why Intermedia does not support this full functionality? What are the actual values associated with those 5 discrete enumerated constants? Will the compression percentages associated with them change through versions?

We are looking into this in the future.

Capture images (JPEG) from IP-Camera

Hey there!
I have been trying to capture images from an IP-Camera. I understand that this has to be done by using a custom DataSource and I have tried many many example found here on the net, but with no results.
I think I've tried every piece of code found here at this forum regarding this subject.. :/
The best I could do was not getting an error while creating a custom DataSource from a BufferedStream..but the when I try to configure/realize the Processor - created with Manager.createProcessor(customdatasource) - it gives me an error which, I think, has something to do with unrecognized content..
I could post all the examples I tried but I think it would be too much of a confusion so...does anyone have a full working example of code to achieve this? WITH the frame grabber class? plizzzzzzzzz?
Thanks,
Edd

I felt Captfoss' solution was inspired and so gave it a go. The following builds a video from an ip cam jpg stream using a version of Sun's JpegImagesToMovie.java. It is hacked together quickly and with scope for improvement, but it works, proves the idea, and is a good example.
Run as:- java JpegImagesToMovie -w 320 -h 240 -f 30 -o file:test.avi

How to set a uniform display size of multiple intermedia image types - wher

I have read "If you want to limit the size of the file that can be uploaded, you can do this as a post generation
step, by adding the maxFileSize property to the <controller> element in the struts-config:
This does not address how to limit the *** display size *** where you have multiple intermedia image types - where the original size is not uniform.
If an image is uploaded where the true image display size is 1024 x 768 - it will display that way in the table/table-form. This will create un-even display size's where previous images sizes where different 384 x 384 and so on.
Is there a way to encode the display size so that *** ALL *** images regardless of their true size are displayed uniformly at least on one dimension (64 x ???)? This is possible when using products such as Dreamweaver or Flash.
BTW - JHS/***JDev*** synergy is truely magnificient!!! Way-To-Go Oracle!!!!!!!!!!! Keep it up!!!!
BG...

Bill,
I did some tests, and was able to reproduce it. The problem is that JHeadstart distinguishes between display types fileDownload and image, but UIX uses the same <media> tag to handle both display types. It will look at runtime whether it must render a hyperlink to download the document, or to render it right away as an image.
To get all images the same size, you can set the display width and height, AND the display type must be set to image.
However, to get the file name used as download link, you must set the FileName attribute AND the display type must be set to "fileDownload" ..
So, to solve your problem, it is easiest to set the displayType to "fileDownload" and set the width and height properties post-generation in the generated UIX page.
In the next release of Jheadstart, we will fix this, and always pick up width, height and fileName settings regardless of the display type.
Note that you should also set the FileName property against the attribute you are using to upload the file.

why are some of my still images (jpeg) Ok in my timeline, but skewed ofter output?

Skewed? Left or right? Could you post a screenshot? What format is your timeline? What is the frame size of the JPEG?

Convert canvas.toDataURL('image/jpeg') to java.sql.Blob.
I am using oracle adf so I am able to action a backing bean from javascript and pass in parameters as a map. I pass in the canvas.toDataURL('image/jpeg') which I then try to decode in my bean. Using BASE64Decoder and the converting the bytearray to a file I can see the image is corrupted as I can't open the file thus converting the bytearray to blob is also a waste.
Has anyone any ideas on base64 encoding from canvas.toDataURL to file or Blob?

Use Case:
A jsf page that enables a user to take photos using the HTML5 canvas feature - interact with webcam -, take photos and upload to profile
1. I have created the jsf page with the javascript below; this pops up as a dialog and works okay and onclick an upload image, triggers the snapImage javascript function below and sends the imgURL parameter to the serverside managedbean

function snapImage(event){
                var canvas = AdfPage.PAGE.findComponent('canvas');
                AdfCustomEvent.queue(event.getSource(),"getCamImage",{imgURL:canvas.toDataURL('image/jpeg'),true);
                event.cancel();

public void getCamImage(ClientEvent ce){
String url=(String)ce.getAttributes().get("imgURL");
decodeBase64URLToBlob(url);
private BlobDomain decodeBaseB4URLToBlob(String url64){
                BASE64Decoder de=new BASE64Decoder();
                byte[] bytes=de.decode(url64);
                File file=new File("abc.jpg");
                InputStream in = new ByteArrayInputStream(bytes);
                BufferedImage bImageFromConvert = ImageIO.read(in);
                in.close();
                ImageIO.write(bImageFromConvert, "jpg", file);
                return createBlobDomainFromFile(file);
----problem---
Accessing the generated jpeg file shows the image is corrupted, probably missing bytes or encode/decoder issues.and the blob image after uploading to database is saved as a binary stream which ondownload doesnt render as an image or anything i know of.
Is there anyways of achieving the conversion without errors?

InterMedia Image with Pro*C?

Can I write InterMedia Image application with Pro*C? Where may I get more information?
Thanks,
Louis

I am sure you can. But we don't ahve any pro*c examples. We dor have an OCI example in "c". That might be helpful. It is in <ORACLE_HOME>/ord/img/demo/imgdemo.c
The above should be a good starting point, you might want to ask in the proc*c forum how LOBs are handled.

Hi Massif,
if you set the picture depth to 1 you can´t have any color in it. Use 24 bit and change the background color. Or another solution, save your picture as bitmap, open it and save it as jpg. See the attached example.

Unable to set action of opening image/jpeg in Firefox

I just want to open and view a jpg link in a firefox tab, but it instantly ask me if I want to save it or open it by other application. Fine. I go to Options - Applications to change the action of handling jpg. There are 2 kinds of jpeg, one is "JPEG Image (image/jpeg) and the other "JPEG Image (text/html). I can change the action of "text/html" to use Firefox as the default action, but for "image/jpeg", no matter how many times I tried, it just doesn't allow me to choose Firefox but other actions or applications. Precisely, I can choose Firefox in the "Select Helper Application", but after I clicked "OK", it reverted to the old action. I tried to restart Firefox and tried again, but no good at all. It frustrates me so bad.

Try to delete the mimeTypes.rdf file in the Firefox profile folder to reset all file actions.
*http://kb.mozillazine.org/mimeTypes.rdf
*http://kb.mozillazine.org/File_types_and_download_actions#Resetting_download_actions
Note that the extension will allow to open this image file in a Firefox tab as that is the purpose of this extension.

How do I grab an image (Jpeg) of a Network camera?

There was a question 3 years ago, which remained unanswered: How do I
grab an image(JPEG) from the Web(http://) using the datasocket in
LabView?(http://forums.ni.com/ni/board/message?board.id=200&message.id=847)
I have the same problem. I would like to capture the image of an AXIS
2006 wireless Network Cam with Labview, for further processing. A
sample image with such a cam is available at:

If you just want a URL, you can use this example, which someone posted a while back.

Start up Image (.jpeg) for a .flv

Is there a way to have a nice start up image (.jpeg) showing instead of the 1st frame of a .flv without creating a .swf . in Flash.
Looking to create it using html code- is this possible???

You shouldn't need to create another swf file. You should be able to set the poster frame in Flash for a Flash Video. Here's a good tutorial on it:

Problème de mise à l'échelle (non voulue) à l'importation d'images JPEG dans InDesign.

Bonjour, lorsque j'importe un image JPEG (sans création de bloc image au préalable) celle-ci se voit appliquer une mise à l'échelle qui la réduit, alors qu'elle devrait être importée à 100% de sa taille. Comment éviter cette réduction à l'importation sachant que j'ai ce problème uniquement sur l'import des JPEG ? Merci.
Voici un exemple du problème : je crée un carré bleu (pour faire simple) sur Photoshop, de 800 pixels de côté, j'aplatie mes calques, j'enregistre en JPEG.
Lorsque j'importe ce carré bleu dans mon document InDesign (sans avoir créé de bloc image), celui-ci est importé en subissant une mise à l'échelle de 50%
et il ne fait donc plus que 400 pixels de côté au lieu des 800 pixels. J'ai ce souci qu'avec l'import des JPEG (j'ai re-enregistré ce même carré bleu, en Tiff, en PNG
ou même en PSD et il est correctement importé à 100 % de sa taille dans InDesign). Pourquoi l'import des JPEG pose t-elle problème avec cette réduction de taille ?
Y a t-il quelque chose à paramétrer, une option, une préférence ?

Même pour le résolution le conseil était quand même bien venu car parfois
on peut passer à côté de choses évidentes^^, mais là j'ai cherché partout,
j'ai regardé dans les préférences InDesign, j'ai regardé dans les options
d'importation, j'ai fouillé partout et rien. Je n'avais pas non plus ce problème
d'import auparavant. Je me dis que c'est peut-être un bug qui est apparu
soudainement vu que ça fait longtemps que je n'ai pas formaté l'ordi et que
ça doit être un sacré bazar dans les fichiers systèmes ou dans la base de registre^^.
En attendant oui je vais utiliser ta solution de créer un bloc image et d'y importer
l'image puis faire "ajuster le bloc au contenu", c'est ce qu'il me reste de mieux à faire.

InterMedia Image Accelerator for 9i?

Hi
I am using interMedia in oracle 9.2.0.6 and I am finding that the process method is unacceptably slow.
I checked on metalink and found that there is something called the interMedia Image Accelerator which when intalled speeds up the process method. The note on metalink was related to Oracle 10g - does the Image Accelerator exist for version 9i too?
thanks
paul

Yes the Image Accelerator is critical for image performance on 9.2 Refer to Metalink note 277612.1 for information on how to determine if you are running with the accelerator (or NCOMP as it is often called) installed.
If you find that your are running without the NCOMP libraries, then you will need to install the accelerator libraries from the companion CD of the base 9.2 release (9.2.0.3). Then you will need to re-patch the database back up to 9.2.0.6, your current patch level. The re-install of the patches will apply the patch updates for the NCOMP components. These components would not be patched if they did not exist in the original database.
Finally, have you read the documentation on tuning LOB performance? This is Chapter 11 of the Oracle interMedia User's Guide for 9.2.
please post your findings and let us know if we can help you more.

AQ message containig image (jpeg,tiff...)

Hi,
I need to build an app that buils a AQ message containing an image (jpeg,tiff...)without any Oracle SW installed on that box.The message will then be enqueued
to a AQ queue on a remote system.
1st - Is it possible to have a message containing a queue?
2nd - Do you think Java and AQ Java API is the best solution?
Thanks.
Luis

If you do not need any Oracle SW at the client build an XML message using the IDAP specification (supported in 9i) and post it to an AQ servelet running where your database queues are located. This will gice you maximum independence at the client side. The XML/HTTP message can be generated using any language and needs only to follow AQ's IDAP spec.
