Transformer un format image JPEG en calque transparent DNG

Bonjour
Comment puis je transformer une image en format JPEG en un autre format, comme DNG fond transparent.
Le but étant de mettre cette image en calque incrustation ou superposition ou produit dans une autre image pour faire du compositing ?
(le résultat étant comme les fichiers que l'on peut télécharger gratuitement ... , afin de les faire moi-même)
merci de votre aide
Bien cordialement
Christiane DELBECQUE

Raw formats do not support transparency therefore DNG is the wrong choice to begin with. That and of course your choice of format should/ will be driven by how people are actually able to open your file, meaning it will have to be TIFF, PSD or PNG. You can create transparency in a variety of ways using selections and so on, but really, this is something for which you can just read the help or watch a tutorial on the Internet. The rest is not relevant - even if you provide the file with transparency, it doesn't automatically mean that people will not need extra steps to actualyl use the transparency info.

Is there a practical size limit on JPEG format image files?

I have noticed when working with Photoshop v7.0 on Windows XP that, when creating a JPEG format image file from a very large scanned image (more than 800 Mb, maybe), the .jpg file will usually be saved on disk at any of the possible compression ratios available, without any reported error, yet when the saved file is re-opened, an error is reported - something along the lines of "missing or corrupted end of file marker" - and the image cannot be loaded.
If before saving the original image is substantially reduced in size, e.g. by reducing the resolution of the image, a viable JPEG format file can be created, which will subsequently load successfully, though technically with data loss.
This appears to happen only with JPEG format files - PDF format files can be saved from the original image at similar JPEG compression ratios, without error on reloading.
I do not know if this also occurs with any other Photoshop versions. I am working with Adobe Photoshop v7.0 on Windows XP, although we are preparing to upgrade to CS (which version I don't know) in the near future, for different reasons to those which are detailed above.
Does anyone know if there is a technical explanation for this behaviour? Is there a file size limit for writing viable JPEG files (which Photoshop does not report as an error when exceeded)?
Thanks

that's what I gathered from "JPEG cannot [...] in Photoshop (code difficult to replace)".
But if you say this is in the works right now, that's good news indeed.

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.

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

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

Change photos from PDF format to Jpeg

how do I change photos from PDF format to Jpeg?

Welcome to Apple Support Communities.
Open the existing pdf file with Preview.
In preview, select File, Save As, and click on the Format window to change PDF to JPEG.
Then click the Save button.
Quality may suffer in the translation from one format to another.
In a quick test, changing Quality to 'Best' and Resolution to 300 dpi, the text in my sample page was crisp, but the original photo area was very pixelated.
The original image in the pdf file was also pixelated when viewed at 100%
A portion of the test image and text at shown at 100%. (Click on the image to view full size):

jpg does not support Layers.
Just to make sure, what exactly do you mean by "stacking photos" and what do you want to achieve thereby?

When you make a DNG that's like making another raw file, so you will need to convert the DNG file just like your original raw. Don't use the Save button in the raw converter. That's just a link to the DNG converter. Normally you would click Open instead and then save in the editor as a jpg or other image format of your choice.

How do I place a large format image into Illustrator

I am trying to place a large format image that I created in Photoshop into Illustrator. I have tried PSD, TIFF, and JPG. I have even cropped down the image into smaller portions to try to make it easier to work with. Every time I try to Place the image I get a dialogue box saying,"The file 'Water 1.jpg' is in an unknown format and cannot be opened.' Can anyone help with this?

I would guess the file is simply too big. Make sure the document is in RGB mode. If I were you, I would never submit a file that size at 300ppi for large format. Large or grand format printers only need around 100 to 144ppi at 100% final size. Also, set the Illustrator file up at 25% scale and place the image at 25% @ 300ppi ( image resolution ends up around 75ppi which is still plenty when enlarged 400% to final size ). Getting back to the original error message, it could be the system is running out of both RAM and scratch disk space and cannot deal with the preview required. Better to scale the file down for large format.

Sorry I'm new to Final Cut Express. How do you make an image (jpeg file for example) move across the screen slowly as I've seen in many films.

Writing XMP to multiple file formats (PDF, JPEG, TIFF, etc)

Hi,
I am developing a server-side component that embeds XMP data into a file (of various formats) and then provides these files for client download.
I have been using the XMP toolkit for generating the metadata, however i now have the problem of getting this metadata into the relevant file. I could always develop this myself but it seems like a huge amount of work. So to make my life easier, does anyone know of any toolkits (from adobe or otherwise) that support writing XMP data into different file formats (PDF, JPEG, TIFF, AIFF, MPEG etc) ??
I am developing in Java so I would prefer Java libraries, however I can always use JNI calls to C/C++ (as i have with the XMP toolkit).
Any help would be very appreciated.
Regards,
Jude

Greetings,
I think we should standardize some information, I know for a fack, that I will support adding XMP metadata in the HDF, RIFF, IFF and OLE file formats. If you have any specific suggestions on the chunk information or signature information that I should use, let me know?
For my part, I was thinking of adding RIFF,IFF chunks with the name \ xmp in those file formats. For OLE, maybe an added stream with the xmp name (in UTF-16).
Comments welcome everyone!

Get canvas.toDataURL('image/jpeg') and convert base64 encoding to java.sql.Blob

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?

IPhoto causes portrait format images to sort incorrectly in iOS

After importing photos into an Event in iPhoto, then on quitting iPhoto, the portrait format photos within that Event have their modification date/time changed from the creation date/time (which is what it should be) to the date/time that the photo was imported into iPhoto. This causes the Photos App under iOS 6.0.1 and above to sort the photos within that Event so that all the landscape format images are displayed ahead of all the portrait format images. This is because the iOS Photos App incorrectly sorts on modification date/time rather than creation date/time.
Steps to Reproduce: Take a number of photos with a camera that records orientation information in the EXIF data (e.g. Nikon DSLR or similar). Ensure there is a mixed assortment of both landscape and portrait format photos. Import those photos into an Event in iPhoto (with Sort by Date selected). You will see in iPhoto that the images are sorted correctly in chronological order. Examine the Info (CMD-I) on both types of image, and you will see that modification date/time is the same as creation date/time for every image (as it should be). Now quit iPhoto, and relaunch it. In iPhoto, look again at photo Info (CMD-I) of photos in that Event, and you will see that all of the portrait format images have now had their modification date/time changed to the date/time of import into the iPhoto library. Using iTunes, sync that Event with an iOS device (e.g. iPad). On the iOS device, look at the Event in the Photos App, and you will see it is sorted incorrectly, with all the landscape images first, followed by all the portrait images.

Sigh. I know I'm being troll bait, and I really don't believe you can be so obtuse, but I'll have one last stab, just in case you're genuine.
Point 1. Nothing on your Mac needs iPhoto. Every application on your Mac can deal with photos as files, without intervention or advice from iPhoto. Even the Finder gets it right, orienting the images correctly from EXIF information. Even Quicklook gets it right. You can remove iPhoto from your Mac and everything will continue to display images correctly. There is no need for iPhoto to change mod date in the EXIF data on a photograph inside the iPhoto library, simply because the camera was oriented vertically instead of horizontally when the picture was taken. It helps no-one and the only thing affected, adversely, is the Photos App on iOS.
Point 2. If it were really the warped intention of iPhoto developers that vertically oriented photos should be considered to have been modified when they were imported into the iPhoto library, then iPhoto should treat them the same as it treats other photos modified in iPhoto. It should put a copy of the original file, as modified, into the Modified section of its library, and it should leave the original in the Originals section. And it should offer a 'Revert to Original' option. It does not do that for these vertical images. There is no copy in the Modified part of the library. And 'Revert to Original' is greyed out, unobtainable.
Point 3. It is only in the past 5 or 6 months that iPhoto began clobbering the modification date of vertical images. For the previous 9 years that I've been using iPhoto and the 18,000 images in my iPhoto library, everything had been fine. Only the vertically oriented photos imported into iPhoto since version 9.3.2 have had their mod date trashed. This is a pernicious and no doubt unintentional bug, that fortunately impacts nothing else on the Mac (and assists nothing else either). It does affect the Photos App on iOS. It might affect the iPhoto App on iOS too. I don't know, as I don't have it.
Point 4. The iOS Photos App is also incorrect in sorting on mod date instead of creation date. This began with iOS 6.0.1. I have also submitted a bug report to Apple on that issue.

Excel Rendering Extension: Unknown Image Format Imag/GIF - SSRS Excel Export

We are using the SSRS 2012 [ExportOpenXML].
When a report is export to excel, getting the message Unknow Image Format IMage/GIF.
Please suggest a fix the above issue.
As per article Excel Rendering extension: Unknow Image Format image/x-png suggestion verified in Visual studio selected the gif file in the Solution Explorer panel, checked the Properties
the MIME Type which is already set as image/gif.
Note: Dev environment its working as expected and but issue is observed in QA environment. I wonder some setting is missing on QA enviornment which I'm unable to get the difference exactly.
Quick help would be higly appreciated.

Hi Niranjan,
Based on the current description, I understand that there should be no issue when exporting the report containing image which is Image/Gif type in Dev environment because you have changed the MIME type to Image/Gif.
To narrow down the scope to find the cause, I want to confirm some information below:
1. Check Reporting Services edition in QA environment, if the Reporting Services edition is same between QA and Dev environment, you can back up the .rdl file and copy the .rdl file to QA environment and then export the report in Excel format to check
whether the issue persists.
2. If you export the report to other format such as PDF rather than Excel format in QA environment, please confirm whether the issue persists.
3. If you change the MIME type to Image/Png and then export the report to Excel in Dev and QA environment, please confirm whether the issue persists.
Supposing there is error message, please post the details to the forum for further analysis.
