Export as CMYK jpeg

Greetings,
I tried to search, but couldn't find exactly the answer I was looking for. I need to export images as jpegs in the CMYK profile for printing in a catalog. Can Aperture do this?
Thanks,
Josh

Aperture will not export a jpg with CMKY.
You will either need to use tiff or do the conversion to CMKY external to Aperture.

How to set "embed icc Profile" option to export document as JPEG

Hi All,
While exporting the document as jpeg, through File->Export, there is an option "Embed ICC Profile" as figure shows.
How to set it if I am exporting the document through my program in which I rasterize the document and used
the sAIImage->AsJPEG(raster, jpegDataFilter, params);
I didn't find any option in AIRasterizeSettings or AIImageOptJPEGParams to set this flag.
plz anyone suggest me how to do so.
Thanks,
Rud.

thanks for you through out help.
I use the folowing code which executing properly,but there is no effect on JPEG whether the value of jpegparam.s.jpeg.embedICCProfile is 0 or 1.
/////Start
ASOptimizationSettings jpegparam;
jpegparam.fileFormat = asffJPEG;
jpegparam.s.jpeg.embedICCProfile = isICCProfileEmbeded;
ASInt32 optID;
optID = sAIOptSet->GetUniqueOptimizationSettingsID();
error = sAIOptSet->SetOptimizationSettings(optID, &jpegparam); // after executing this line error = 0
/////End
I guess it would work when we export document as jpeg through AIActionManagerSuite
not with rasterizing the layer's art and then exporting them as JPEG using AsJPEG().
thanks

How can I load a CMYK jpeg image

How can I load a CMYK jpeg image (originally saved from Photoshop) and then
turn it into an rgb BufferedImage, in order to display it on screen in an
applet?
I first tried ImageIO.read(), but that does not work for cmyk jpegs. I then
looked into the com.sun.image.codec.jpeg package, and tried methods like
decodeAsBufferedImage() and decodeAsRaster().
The first one (decodeAsBufferedImage) returned an image, but it seems that
it was interpreted as an ARGB, and the colors were incorrect.
I then read the documentation which (amongst many other things) stated that
"If the user needs better control over conversion, the user must request the
data as a Raster and handle the conversion of the image data themselves."
This made sense, so I took to decodeAsRaster(), only to find that I could
not figure out how to carry out the desired conversion.
Of course, I have looked into the documentation for BufferedImage, Raster,
ColorModel, ColorSpace etc, but after a while I was lost. (Before I got lost
I read that you can convert images with the help of methods like toRGB,
toCIEXYZ.)
I have a feeling that this is probably pretty simple if you just know how to
do it, but I sure would need some directions here.
Any help would be appreciated. Thanks.

You can either use the "Place" command from the main menu, under "File", or you can just open it, select the move tool "V", the click in the image and drag it to the other file's tab.

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.

ICC profile to convert RGB to CMYK,   jpeg is ok, png format have a problem

When I use ICC profile to convert RGB to CMYK, jpeg format is ok, but png format have a problem.the color is lossy.
It means, the png file color is shallow than jpeg file after convert.Could anybody help me?

Hi,
I am having similar problems. I have read somewhere that png format can not handle CMYK colorspace anyway, which I find odd (and plainly stupid IM(NS)HO) which would mean that converting to RGB and therefore using profiles is mandatory.
May be you should check if the internal format of the png files claims it is RGB or CMYK (using ImageMagick's "identify" command for example).

Export xmp from jpeg

Hi,
Photographer I use Internet in lots of coutries.
I have to work in jpeg and i want to export XML to send by Internet.
So Can I export XML from JPEG ?
Can I see the modifications if I put the sidecars XML in the directory of jpeg without modifications ?
Thx for your help
BLL

With ExifTool you can export xmp from jpeg to xmp files and vica versa. Just make sure you have the last version that support all your tags. And of course save the metadata to the jpeg file before you start using the tool and read the metadata after you done.

Preview - saving resized CMYK JPEGs

I can't save a resized CMYK JPEG with Preview:
Take a JPEG, any JPEG.
Duplicate it, make an RGB and a CMYK version (create whichever one did not already exist) using
GraphicConverter or a similar tool.
Open each in Preview and use "Adjust Size..." to adjust the resolution.
Save. RGB version saves fine. CMYK version fails with "The document 'CMYK.jpg' could not be saved."
Can anyone confirm or deny?

Just been bitten by the same problem. It seems to work fine on Leopard but seems broken in SL?

Exporting full size Jpegs from DNG converted files

Hi there
I imported some RAW files into Lightroom 4, which I then copied/converted to DNG, then edited them. I now want to export them as full size, high-quality jpegs but I only seem to be able to export them at a maximum of about 800kb, which is far lower than full-size. Is this to do with first the conversion to DNG from RAW on the import? Am I best copying them from raw and not converting them to DNG at all? Next question is, will I have to import the original RAWs again and re-edit them to be able to export as full-size high quality jpegs or is there some way to not have to do them again? Many thanks, Sophie

The curious thing is that when I try to export full size jpegs through the email function,
Do you mean exporting through the e-mail the EXACT SAME photos that you were discussing above?
Have you done any cropping of the photos? What is the size, in pixels, of one of these photos according to Lightroom? What is the size, in pixels, of the corresponding exported photo, according to your operating system?
Can you show us screen captures of the export dialog box?
At this time, I am not going to deal with the print at A4 size being pixelated, as printing introduces a lot of other places where something can go wrong. To see if the problem is in the export, I want to know if you look at the exported photo outside of Lightroom, does it appear pixelated or not?

I see inconsistent ImageNew() failures for CMYK Jpeg Images (CF10)

Weird problem.
I have a set of test cases that pass just fine loading a known CMYK jpeg via ImageNew(). Later, with no restart of the app server, these same test cases fail. Again, after a while, the test case passes again. I've dug into the Java a little bit, and I wonder if the ImageReader implementation being used doesn't switch out once in a while -- like maybe a hashtable of ImageReaders reorders or something.
I know the CMYK is only partially supported, but I could get data with ImageNew and ImageInfo showing it was a CMYK file, then later on, it would throw "Image Not Supported" errors.
Anybody have knowledge of these inner workings to provide some insight? Smells a bit like a bug to me, but I can't consistently replicate it.
-Dave

From what I can tell, it does appear to be a bug. I have submitted a bug report to Adobe on it.
https://bugbase.adobe.com/index.cfm?event=bug&id=3596008
What seems to be occurring is that coldfusion.image.ImageReader is trying to find the CLibJPEGImageReader class from the collection returned by javax.imageio.ImageIO.getImageReadersByFormatName("jpeg"). This works fine if it is the first object returned in the collection, but if not, it will return another JPEG ImageReader that does not support CMYK images. I have two systems (both RedHat) which are currently in each state. One has the CLibJPEGImageReader as the first element in the ImageReader collection, and in the other, it is the second element in the collection. The code below will work fine when the correct reader is found, but not when it isn't the first element in the collection.

Exporting document as jpeg using kAIExportDocumentAction creating html file also

hi,
I used this action (kAIExportDocumentAction) to export the document as jpeg.And it is creating a html file aslo.
And also it not prompt the "JPEG Option" dialogbox. When I set the kDialogOff to kDialogON it shows first the" Export Dialog" .
is there any way to get only "Jpeg Option" dialog box while exporting through this action?
plz Help!!!
here are the code ....
ai::FilePath filePath(ai::UnicodeString("C:\\Documents and Settings\\rudreshp\\Desktop\\Export\\rudresh\\hi.jpeg"));
AIActionParamValueRef actionParam;
//create a new action param value.
sAIActionManager->AINewActionParamValue(&actionParam);
//include the path where to save
error = sAIActionManager->AIActionSetStringUS(actionParam, kAIExportDocumentNameKey, filePath.GetFullPath() );
error = sAIActionManager->AIActionSetString(actionParam, kAIExportDocumentFormatKey, "JPEG file format");
error = sAIActionManager->AIActionSetString(actionParam, kAIExportDocumentExtensionKey, "jpg");
error = sAIActionManager->AIActionSetBoolean(actionParam, kAIExportDocumentSaveMultipleArtboardsKey, false);
error = sAIActionManager->PlayActionEvent(kAIExportDocumentAction, kDialogOff, actionParam);
//delete the actionParam
error = sAIActionManager->AIDeleteActionParamValue(actionParam);

The export document action is an action for exporting the doument as you have seen, it is not a Export Jpeg action.
So, no it is not possible with the export action.

Aperture won't export full-size jpegs

I'm trying to export full-size jpegs, but Aperture is sending out 24 KB images. I'm selecting the edited versions I want, then going File>Export>Version. I have the dialog set to JPEG - Original Size. Still, what comes out is a thumbnail.
Aperture 3.4.5
OSX 10.8.5
MacBook Pro
2.4 GHz Intel Core 2 Duo

Check, if your export preset "JPEG - Original size" is still set correctly.
In the "Export" panel set the "Export Preset" pop-up to "Edit".
In the "Edit" panel make sure, that "Size to" is set to "Original Size", and the quality to a high value, at least 10.

How do i export a single jpeg frame from a video file in final cut x

how do i export a single jpeg frame from a video file in final cut x

You can also use the 3 finger method of COMMAND+SHIFT+4, then drag across what you want to copy from the image. That will show up on your desktop, which then you can edit using Photoshop, if you want too.
You can then change the file format from a PNG to either a .JPG or TIFF or even a Photoshop image.
Make sure, you have stopped the playback, to what you want to save as a still.
Either method works, to make a still image from video.

Exporting RAW into JPEG, color differences

I've done a lot of searching in these forums and I can't find a solution to my problem. I just spent 30+ hours editing a set of 123 wedding photos in RAW file format. When I export to JPEG, the colors change on just about every photo. I understand that if I would have correctly set up the camer calibration prior to editing, this would have possibly solved my problem. However, the photos are already edited. When I export the files in TIFF, they look fine. It's just the JPEG file format that changes the look of my images. I'm using Lightroom 2.3. My last brainstorm involved importing the already edited TIFF files and then trying to export those into JPEG, the color format was still off. Can anyone Help?

What program do you use to look at the jpegs?
Is your screen calibrated?
What OS are you using?
There is a free upgrade available for you to the latest LR2 version 2.7. Win and Mac

Exporting RAW to JPEG and TIFF

Evaluating LE to hopefully improve some workflow. I noticed however, that when export to a JPEG or TIFF format the file size seems much smaller that I'm accustomed. A D100 9.5MB RAW file converts to appx 2.7Mb JPEG at 100% and appx 7MB in TIFF. Currently when I convert I get a 17-20MB JPEG. I'm I missing something in the setup or is this the larger file size LE produces.

Excuse me Lightroom. I currently use Portfolio 8 to review and tagged a large number of images for production. They have a conversion process that allows you to convert a NEF file to JPEG or TIFF. When converting to from a NEF file that is appx 9.5MB in size to a JPEG at 100% @300DPI which is what my clients require, it produces a a JPEG file that ranges from 17-23MB depending the amount of information. But I still have to pull that image into editing SW to do some cleanup or slight exposure adjustments. It was my hopes that by using Lightroom, I could slimline a couple of these processes. But if LR only provides a exported JPEG file size of what I've seen thus far, then I would unable to accomplish this.
Is this better clarification of my question?

Trying to export as a JPEG 2000 but very jumpy when I view it in quicktime. Is this just because the player doesn't support JPEG2000?

JPEG2000 for a digital projector? The option you see in Compressor, or the QT export is NOT the format they need. You can only make that with special software. I had that asked of me to deliver, I tried using Compressor and the JPEG2000 codec...and it wasn't right. Ended up sending it out of house.
FYI
