Unable to process Lossless JPEG Images..

Hi,
I have jdk 1.6.0. and i installed the jai-Imageio pakage.i am not able view the true lossless jpeg
image.
I tried to open a lossless jpeg image from the code given in
http://forums.sun.com/thread.jspa?forumID=20&threadID=335960
but the
image does not open. It works for jpeg, jpeg2000 images. but not
lossless jpeg and jpeg-ls images..
when i try to code
String s[] = ImageIO.getReaderFormatNames();
for(int i=0;i< s.length ;i++)
System.out.println(s);
it prints

if i check with 'cl.canDecodeInput(imageInputStream)' it returns true.
i d't now how to load the image using 'CLibJPEGImageReaderSpi' class object
or is there any other way to load the image ?
can anybody write the full code to display the true lossless jpeg image
which is taken from dicom medical images. the images are available at
http://rapidshare.com/files/250911269/Lossless_jpeg.zip.html
is there any website has good tutorial about lossless jpeg image. what
is point transform in lossless jpeg ? what old pseudo lossless jpeg ?
what is equivalent for that in java ?

You can email me one of the Pics (zip it first) but it sounds like they are toast.

There are two images in that zip file. I have no problems reading the one called "lossless.jpg". It's a 16-bit grayscale image that's completely black. The one called "test.jpg" throws an exception. Is this what you're getting? I'm using JAI-ImageIO 1.1
is there any website has good tutorial about lossless jpeg image. what
is point transform in lossless jpeg ? what old pseudo lossless jpeg ?
what is equivalent for that in java ? In addition to describing normal jpeg encoding, the jpeg specification also describes what's called "lossless jpeg" encoding. Lossless jpegs - as described in the original specification - are obsolete. No common application can open them. It doesn't help that the png format (also lossless) provides much smaller file sizes then lossless jpeg's.
Both of the jpegs in that zip file are lossless jpegs. Incidently, I can't open them up with Irfanview or Adobe Photoshop CS4 (wich says alot). And I can only read "lossless.jpg" with JAI-ImageIO while the other one throws an IOException. By using lossless jpegs, the user cripples portability.
JPEG-LS is different from lossless jpeg. In fact, it was meant to replace lossless jpegs. While not actually lossless, jpeg-ls is described as a "near lossless" compression. I believe the files have a +.jls+ extension instead of a +.jpg+ one. While not obsolete (I think), JPEG-LS is not widely used. Using it can still cripple portability.
The JPEG2000 format also has a "lossless" mode, that again, is not widely used. Using it can still cripple portability. JPEG2000 files have a +.jp2+ extension.
Lastly, I don't know what you mean by this question
what is point transform in lossless jpeg?PS: I have no problems reading a lossless jpeg or a jpeg-ls that I write with JAI-ImageIO. So maybe there's something wrong with "test.jpg" in the zip file?

Unable to open saved JPEG images

I opened and modified several JPEG images with Photoshop CS2. Now none of these files can be opened by Photoshop or any other program. All of the files seem to have a non-zero size, but when I try to open them in Photoshop, it does not generate an error, it merely offers to create a new file with the same image properties (size, etc) as the saved image on disk.
I've also tried several other programs to open these files, and none of them can open them. FYI, one thing that all of the files have in common is that they are all saved with the absolute minimum compression settings.
Any assistance in helping me to recover these files would be greatly appreciated.
Thanks.

Unable to open saved edited jpeg image

Not being the most techie type person, sorry if this is repeated in numerous place on the forum. I can see, and open, the images in thumbnail form in my 'Picture - Library'. I can then edit them in PE 10, but when I 'save as' (and I save as jpeg image with a version of IMG_****.jpeg copy ) the 'copy' jpeg thumbnail appears in the library as a blank page and no image. I'm then unable to open the 'saved' copy as it's the 'wrong type'. I've tried numerous images but to no avail. Any advice will be greatly appreciated.

Change IMG_****.jpeg copy to IMG_****copy.jpeg

I am unable to import Raw still images from a Nikon D 80 into Premiere Pro cs 4. All jpeg images ok

I am unable to Import RAW still Images from a Nikon D 80 camera into
Premiere Pro. All jpeg images import Ok. A web search suggests I need "plug-ins" for RAW, but I can not find same. Any suggestions as to how to inport RAW files to PP CS 4 would be appreciated. I have just updated from Premiere Elements 4 which had no problem importing RAW still images.
Roygo

The way I see it (correct me if I'm wrong) but Raw is supposed to be where you have total editing control of the shot (as opposed to the camera). I believe the next step is to do the editing (i.e. color balance, exposure, etc) then make a regular image from that to use in whatever output you desire (print, web, etc.) Think of raw as the negative. Just being in raw doesn't in it self make it better.
Edit. This is from premiere help files....
Supported still‑image and sequence file formats
Adobe Premiere Pro supports 8-bit per-channel (4 bytes per pixel) and 16-bit per-channel (8 bytes per pixel) still-image files. It converts images with lower bit-depths to 8-bits per channel and images with higher bit-depths to 16-bits per channel on import. High bit-depth files are supported at one single-precision float per channel (16-bytes per pixel).

How to process and imbedded JPEG image data

I am using a flowable XFA form . and i would like to embed some JPEG images in a subform.
My form is working but I need this additional behavior/capability.
Can you direct me to where i would find a good example of how to do it or to good documentation on this can be done or any combination of these two things.
thanks

Hi,
I am trying to understand what you are trying to achieve. If you want to embed a static image, then drag an "image" from the object library. If you want the user to be able to select (or change) the image, then insert an "image field" into your subform.
For what it is worth, I have uploaded a basic PDF with a static image and a dynamic image field.
If you are dictating the images then select "image" objects. If the user has input, then select "image field" objects.
I cannot provide any direction to your second post. If you have the form working with "save as TIFF, I don't know how you would script additional parameters.
Good luck,
N.

Unable to display a PDF image on the page - Mac 10.6

Hi,
Running an iMac with 10.6.8 and Indesign 5.0.4. Just wanting to export a PDF as per usual via File > Export function. However, I keep getting the error message, "Unable to display a PDF image on the page'. No idea what this is and have never seen this error before. The only info on the internet reveals error code 0x2511(9489).
I've deleted prefs, closed down and re-opened Indesign and even restarted the computer. I've also re-linked the images contained in the document and even created a new document and set it up the same, but still the same problem. Investigating further, other Indesign documents still export properly.
The only ones that don't export are 2 documents, both giving this same error message. Both documents are ones where a client has sent a PDF, I've imported into two of these into an 2-page A4 Indesign document (each PDF is 48MB each) and then just added a text layer (using Times) which is properly installed on the computer. I basically have to 'update' course dates for the client and add PDF to the website, all very basic.
I've tried importing a jpeg and other PDFs into the file (replacing the existing ones) and they export fine.
All my software is legal and I've exported this document before now in exactly the same File > Export without any problems (under 10.5 and 10.6).
OK... I've just imported the offending PDFs into Acrobat, optimized and shrunk the file size, re-imported back to Indesign and the PDF export works fine. So it seems InDesign / PDF Export doesn't like large imported PDFs? I think they were originally exported from Publisher, so maybe that's the problem or a file conflict somehow.
Any ideas on the culprit? I've googled it, searched these forums and Apple discussions and haven't found anything. Although I've found a workaround, I do get large files to import and then export. Thanks for any help
Steve

It does sound like a problem with the original PDF files the client sent you. You can check how they were made in Acrobat Pro from the Additional MetaData button on the Description tab of the document properties dialog. It will be under Advanced at the bottom of the list when the metadata opens.
You might be able to salvage them by running the optimzer and not changing the size, or just doing a Save As in Acrobat.

I think it does that for QuickTime if you don't define the lineStride value in the VideoFormat (lineStride = pixelStride * width).

Help with managing RAW and jpeg images and installing iphoto 9

Greetings: Fist, let me make the neophyte apology and plea - I'm sorry, I should have come here first; I didn't and now I need your help.
I have just purchased a macbook pro (still in its box) with updated software for my older imac os x. I have a number of Canon related photo editing programs (that came with my 40D digital SLR) and Adobe photo elements 6 for mac on the imac. Following some erroneous advice I have made a complete mess of the pictures folder's content by trying to delete images directly from that folder (there are now 6000+ images in the folder, many of which are duplicates(?). Most of the images are not tagged or labeled and some have been organized in/by iphoto (I corrupted the iphoto's library structure very early on by disrupting and editing its images - which might explain why iphoto had a difficult time 'finding' and displaying some of my photos). The picture folder now holds jpegs, smallRAW images (a Canon 40D photo format) and various duplicates of the orignal images - (some of the duplicates don't display as images, but as jpeg logos, which, when opened contain duplicate image or are completely black) The first time I downloaded RAW images into iphoto 6 the RAW data displayed as a black image. When shooting in smallRAW on the Canon 40D, the camera produces a jpeg image for 'easy viewing and editing in the camera' but it looks as though iphoto 6 made duplicates of the jpeg and the RAW data and stored them in different locals in the picture file. In an attempt to get the number of images down, I have been trying to delete them from the picture folder. (My daughters both download images rather indiscriminately in hopes of 'editing them on the computer' which inevitably does not happen) and there is a lot of experimental bracketing of images - shooting raw and different Camera formats etc., all of which need to be cleaned up before I proceed.
Sometime in the not-too-distant future I would like to have iphoto 9 running on my imac with a clean library of images and a seamless way of downloading, editing and storing images (including the RAW data).
The macbook pro is for my highschool-aged daughter, who will run iphoto 9 but not have any RAW image data on her system. She would like to copy some of the old iMac's images to put into her own iPhoto 9 library (probably using a disk, email or on-line photo service - ideally, I would like to be able to copy and remove a number of those images from my HD and give them to her for the macbook)
A few questions and queries: Can I 'dis-able' iphoto 6, while I delete images (RAW and jpeg) from the picture file? (and is this even a good idea).
Once I have edited the # of images down to a reasonable size, should I re-launch iphoto 6, rebuild the iphoto library and then update to iphoto 9 or skip v6 and rebuild with v9?
And now for the 'how stupid is this guy question' - I really had planned to purchase an external backup; but between new the macbook, car repairs and braces it has never come to fruition. So, I have never properly backed up my images. What is the bare-bones, least expensive method for me to do this? I'd even consider burning everything to disks if that works. I can't afford the $ to purchase a new external hard drive right now (really). Budget is set aside mid-November for one though.
I've been looking through some other discussion boards and it looks like I'm not the only one having RAW image issues. I know that shooting smallRAW with the companion jpeg is probably not helping things but I take my camera equipment on extended canoe trips - and we like the ease of on-the-spot editing with this format.
Thanks in advance for your help - Mark

Terence, Is the picture folder the primary source for the images or does that data reside somewhere else?
If you gathered them there, then yes.
I really don't want to have to go through 14,000 images looking for the pictures that I want to keep (or is that my only option?).
Only you can decide what you want to keep.
Why does the computer keep making copies of the images and filing them under date and events?
That's how iPhoto works. It's not a problem usually, only you did go in there and make a problem, and now we are trying to fix it.
You advise not to muck around in the picture file via preview,
No I don't. I advise not to much around in the iPhoto Library Folder.
but if I download images through a program other than iPhotos - image capture or adobe aren't I doing that anyway?
Adobe what? Adobe is a software manufacturer who make many excellent applications, you need to be more precise. And no, if you import photos with Image Capture or “adobe” no you are not interfering with the iPhoto Library Folder.
Can you edit a base image file somewhere and remove it from the HD without iphoto making a copy of it and storing it somewhere else?
This is stunningly easy. Don't use iPhoto. Use an image editor.
I want to look the negatives, decide which ones I want and throw the rest away. Can that be done or am I way off course?
Yes, and iPhoto (or similar apps) make this really easy.
Hook up your camera. Import the pics to iPhoto. Go through the imported pics. Trash the ones you don't want. Then process the ones you do. But you must learn how to use iPhoto to do this successfully
To trash: put the pic in the iPhoto trash and empty it. This removes the file from iPhoto and the Hard Disk.
Process it: If you want to use another editor: You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

How to make Photoshop save Aperture imported JPEG images as JPEGs

Recently, I upgraded from Photoshop CS 5 to CS 5.1.
My point and shoot cameras record in JPEG format. Often, I'll import those photos into Aperture and then tweak them in Photoshop using the Edit in External Editor command. My preferences for the external editor in Aperture were set to 8-bit, Photoshop
With Photoshop CS 5, I would edit the photo and choose Save and the edited photo would be saved back to Aperture as a new version, in a JPEG format.
Now, using Photoshop CS 5.1, when the imported image from Aperture is converted into a PSD file and when I save back to Aperture, I end up with a PSD file.
How can I revert to how it was before? JPEG image in Aperture, opened in external editor Photoshop as a JPEG, edited in Photoshop, then saved back to Aperture as a new version JPEG?
(Though this question is approached in this forum, a solution to my question is never found as each dicussion ends up going off-topic from the original question)

Any further ideas from anyone who's experienced trying to open a JPEG from Aperture in Photoshop as a JPEG?
Like I said before, you cannot open a jpeg as a jpeg, the file must be decompressed to open in PS or in Aperture, and that has always been the case.
I do not know how it used to work, but I tested and you are correct that with PS 12.1 and with Aperture 3.2.2 a JPEG sent to open in external editor (PS) is opened into your choice of lossless format and then goes back to Aperture in the lossless format you chose.
IMO this is the way it should be, because every save into JPEG loses image data, so such saves should be limited to the final export, in this case when the image actually leaves Aperture. If the file was compressed as a JPEG when leaving PS, decompressed and edited in Aperture, then compressed again to export as JPEG from Aperture, unnecessary additional image data loss would occur.
It is always better to save the application of lossy compression until the very last step in a workflow because other usages (printing, for instance) may occur before applying the lossy compression.

Lose Jpeg images when editing an existing PDF Form in Acrobat X - All other edits update OK

Have just upgraded to Acrobat X and am having problems trying to update an existing PDF Form which includes jpeg images. After all edits are done and I save, previewing the PDF identifies that all of the existing jpeg images within the form no longer display. Unable to figure out what to do to retain these images from the existing PDF.

Hi,
Based on your other post, the original form was developed in LiveCycle Designer. Therefore you would need to edit the form in LC Designer, to reestablish the link to the image files.

Problem displaying CMYK jpeg images

I have a problem with a CMYK jpeg image.
I know that about supported JPEGs in JRE - JCS_CMYK and JCS_YCCK are not supported directly.
And I found here how to load the image:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4799903
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5100094
I used both the suggestions described to load it, but when the image is displayed the colors are wrong, are very different from the one displayed in PhotoShop, for example.
Any suggestion are very appreciated. If it's necessary i can send you the image.

The loading process It takes about 10 seconds, and every repaint it takes the same time.The painting yes, the loading no. It shouldn't take much more time to load the image then an ordinary JPEG. In particular, your now using a "natively accelerated" JPEG image reader, so it should take less time on average to load any JPEG. 10 seconds is absurd. Are you sure your not including the drawing time in that figure?
- Another problem: JAI-ImageIO is not available for MAC OS X platform.This is somewhat true. You can take the imageio.jar file and package it together with your program (adding it to the class path). This will give you most of the functionality of JAI-ImageIO; in particular the TIFFImageReader. You just won't be able to use the two natively accelerated ImageReaders that comes with installing.
Right now, you're using the accelerated CLibJPEGImageReader to read the image. You can't use this image reader on the MAC, so you have to take the approach mentioned in the 2nd bug report you originally posted (i.e. use an arbitrary CMYK profile).
The conversion is too long more than 30 seconds.The code you posted could be simplified to
BufferedImage rgbImage = new BufferedImage(w,h,
            BufferedImage.3_BYTE_BGR);
ColorConvertOp op = new ColorConvertOp(null);
op.filter(cmykImage,rgbImage);But again, 30 seconds is an absurd value. After a little preparation, converting from one ICC_Profile to another is essentially a look up operation. What does,
System.out.println(cmykImage.getColorModel().getColorSpace());print out? If it's not an instance of ICC_ColorSpace, then I can understand the 30 seconds. If it is, then something is dreadfully wrong.
the RGB bufferedImage that i get after the transformation when it is displayed is much more brightThis is the "one last problem that pops up" that I hinted at. It's because some gamma correction is going on in the background. I have a solution, but it's programming to the implementation of the ColorConvertOp class and not the API. So I'm not sure about its portability between java versions or OS's.

Improve quality of JPEG images

Hi
I have an application which saves images in JPEG format after editing (well, many applications does that, but this is only a fraction of what this application does) :-)
I can't use any other formats due to size restrictions. The problem is Image Editing module of this application has operations like line drawing and text inserting. When I save the image, fine lines (especially texts) are getting blurred.
Is there any way I can increase the quality of JPEG files saved? I understand that JPEG is not meant for sharp lines and texts but with Photoshop, even fine lines and texts appear good when saved as a high quality JPEG file. Is there any such method in Java by which I can increase the quality of JPEG images?
Thanks in advance...

I understand that JPEG is not meant for sharp lines and texts but with Photoshop, even fine lines and texts appear good when saved as a high quality JPEG file. Is there any such method in Java by which I can increase the quality of JPEG images?I JPEG is a non-conservative compression format (you do not get back exactly what you put in, it has "acceptable degredaton"--I talked with the author before it became popular and he explained what JPEG was all about--high compresses resulting in a small size for internet communications over dialup.
In more recent times I've seen quality factors brought into play with JPEG, but as you have stated, even in Adobe Photoshop under the highest quality, you still have degradation. I've seen some hint and some state that you can get a lossless JPEG, but I've not encountered it yet.
In any case, if you do find a "lossless JPEG" the size of that file is going to be bigger than you are looking at now. You may consider other file formats--TIFF or there are even more recent files formats that have higher conservative compression algorithms.

Is there a reliable way to determine if the content of a page is a jpeg image?

I have a need to readily detect that the content of a particular page is a JPEG image.......
Is there a way to ascertain this as I am processing each page ?

I see - something more like the following code ? -
Thanks Leonard - I can see that this will take a while but - it is good to know that I am on the right path to start out.
I suppose that I can use the dump type to see what a jpeg looks like , etc.
Thanks again .
