Request: Support DNG as Option to Pass Images to Photoshop

I see you've added the option to Export to disk in DNG format. Love it. But I'd also like to see the option of passing an image with Develop module adjustments to Photoshop and other external editors in DNG format. At the moment, only JPEG and TIFF are supported, but that means a potential loss of dynamic range. If you support DNG as an option for the "Edit in...Photoshop CS5" for example, that dynamic range can be preserved. This would, of course, cause Photoshop to first launch ACR, which is exactly what's expected. Yes, one could make the same adjustments in the LR Develop module as in ACR, but some people use LR only to organize images or only to make certain adjustments and it would be great to use DNG as in interchange format. You already have that capability for Export, why not use it in this way as well? It would also drastically improve the way Lightroom works with third-party external editors/plugins such as Photomatix Pro.
FYI, I've been researching this issue and publishing it on my blog: http://www.blogarithms.com/index.php/archives/2012/01/10/editinproblem/

We don't want to encourage this hybrid workflow, because it breaks many of the auto-update functionality. For example, images edited externally (e.g., DNG edited in ACR) don't get automatically reflected in Lr -- Library preview wouldn't auto update.
More problematic is the file handling. Normally when you do Edit-In-PS, no physical file needs to be generated, because there's already a mechanism whereby Ps can receive output-referred image data. If you tried this with a DNG and opened that in ACR, and clicked the Done button, where do the settings get saved to? Auto-updating the Lr catalog and its settings from ACR isn't an option. The only way to do that would be to write out a physical DNG file, and that would make the Edit-In... feature much slower, and less valuable.
Ultimately, Lr is about streamlining the workflow, and it's unclear to me what is accomplished by moving to a hybrid workflow where the image quality achieved in ACR will be no different than what's achieved in Lr.

Lighroom 5 not passing image to Photoshop 5.1

When choosing "Edit in... Photoshop CS5.1" the modified Lightroom image does not get passed to Photoshop. Instead, the original image appears in Photoshop, even though Lightroom has created a stacked copy. I have uninstalled and reinstalled both Lightroom 5 and Photoshop CS5.1, to no avail. I have a secondary editor configured as as "Edit in..." option, and Lightroom passes the modified image to that program just fine. It just has problems passing the image to Photoshop CS5.1. Is there a setting in the Registry that needs to be tweaked?
Michael

When you use LR5 edit in function you should get a warning dialog that the ACR version in PS CS 5 is not up to date.
If you are not getting this warning, in LR 5 go to edit> preferences> General tab> Prompts > click on "Reset all warning dialogs".
When you next go to the edit in function the warning dialog will pop-up, select render using Lightroom.

Guest LAN and DHCP Options not passing through

Managed to get the Guest LAN up and running for wired clients and all's working well. Users are sat behind a proxy and if I force the use of a appropriate wpad file I can get the WLC auth to happen and then push off to the proxy.
I'm trying to use option 252 in DHCP to present the WPAD url. Only issue that happens is that while the DHCP server on the egress interface is handing out addresses to clients on the ingress interface correctly, the WLC doesn't appear to be handing through the option 252 I have set in DHCP. I've used network monitor to see what the dhcp request process is dishing out in terms of options, and all look good if I'm not behind the WLC.
Anyone know if theres a limitation on the WLC that prevents DHCP options being passed through to the guest LAN?
TIA

When configured as a DHCP server, some of the firewalls do not support DHCP requests from a relay agent. The WLC is a relay agent for the client. The firewall configured as a DHCP server ignores these requests. Clients must be directly connected to the firewall and cannot send requests through another relay agent or router. The firewall can work as a simple DHCP server for internal hosts that are directly connected to it. This allows the firewall to maintain its table based on the MAC addresses that are directly connected and that it can see. This is why an attempt to assign addresses from a DHCP relay are not available and the packets are discarded. PIX Firewall has this limitation.

How can i view nikon images in photoshop? i have cs4 so the camera raw plug-in is not an option and i've lost my disk from the initial purchase of the D90.

how can i view nikon images in photoshop? i have cs4 so the camera raw plug-in is not an option and i've lost my disk from the initial purchase of the D90.

The NEF file only gives a little "nef" icon. i was able to convert the NEF to DNG on the old computer and then brought the files over to the new computer. On the old computer, the NEF files were depicted as little jpeg's so I would be able to see a picture of what each file represented. On the new computer, both the NEF files and the DNG files are depicted with icons, "nef" or "dng", but not as little pictures. On the new computer, though, I am to import the DNG's into Adobe and edit them so that is working regardless of whether or not a picture is present for the icon of each file. I've downloaded the DNG converter from Adobe and will try the conversion directly on the new computer when I get home from work. I do appreciate your responses and will let you know how it works.
I am curious then, since right now the files are represented by little "nef"'s and little "dng"'s: If I also download the viewNX (spelling might be wrong, sorry) from nikon, do you know if that maintains the file as a RAW format file but allows a picture representation of the RAW file for the icon? (That would make it easier to choose which RAW files I would choose to edit and which to not even bother with as an initial culling if that makes sense.
Cheers.

Why no SCALE option for lightbox images?

Need SCALE options for lightbox images!
Must have SCALE DOWN option.
Images must scale down to display correctly on a smaller screen.
Currently Muse Lightbox FAILS on smaller browser screens.
Adobe please include this feature ASAP!

Thanks for the reply
The problem with the Fullscreen Lightbox is that the images scale up and pixelate on a larger browser viewport.
(To avoid this requires a very large image that makes loading slow)
So for Fullscreen Lightbox I would like a SCALE DOWN ONLY option (requested previously). Then the images would not scale up above 100% and would float centred on larger browser viewports (FIT PROPORTIONALLY option used).
And for the standard lightbox a scale option, as requested above, would mean the image doesn't overflow on a smaller browser viewport.
The reason for asking for scale options is to keep images looking their best at 100%, and downscaling for smaller browser ports.

Gateway BOPF Integration - Support of query options $top, $skip, $inlinecount

Hi Experts,
I am using GBI to consume data from a BOPF BO via OData. For some special cases I need the query options $top, $skip and $inlinecount.
But it seems that these query options are not supported until now (I have Component SAP_BS_FND 747 SP04 installed).
Is that true? If yes, is it planned to support the query options in an upcoming version.
Thx for your help.
Florian

Hello Florian,
I cannot speak for GBI and I hope that someone else will have an answer for you. Still I hope that the following might help:
As you are requesting for $top and $skip I guess(?) you have a read-only UI for a large number of entries. If this is the case, upcoming versions might offer a solution for you with SADL-based gateway services. Please refer to this post.
Kind Regards,
Ivo

HT204003 how can i print a boarding pass image file from passbook?

how can i print a boarding pass image file from passbook?

I do not believe that Passbook supports printing. You can email, but not print. Then again I'm not sure what it actually emails, if that is a graphic of the card or what. I'm going to try it with my Starbuck's card, but there is no setting for printing within Passbook.
EDIT: Actually it sends the email as an attachment for a Passbook card file, that cannot be handled by my computer. Hope that answers your question.

Rich text box used in Infopath Form not displaying option to get images from Computer

Hello,
We have used "Rich text box" in Infopath Form which is not displaying option to get images from Computer.
Options available are : From Address, From SharePoint
But if we Rich text box in list, then it works fine with "From Computer" option.
can you please help me out to get this option.
Thanks in advance.
REgards,
Jayashri

Hi,
From your description, there is no “From Computer” option to get images with rich text box in InfoPath form.
Per my knowledge, by design there are “From Address” and “From SharePoint” options without “From Computer” option in rich text box in InfoPath form. As a workaround, you can develop a custom InfoPath Rich Text box to do it.
About developing a custom InfoPath control, I suggest you create a new thread on the forum “Visual Studio Tools for Office”, more experts will assist you with InfoPath development.

Passing images to different views

Hi all,
I am currently working on integrating the camera into an app I am developing (first time working with camera and images), and I am trying to pass images to different views. I have worked with passing text with text fields to labels using prepareForSegue methods, but have not come across any clear examples of tutorials on how to take a photo, and move that captured photo along to different views, pretty much the same as the instagram camera process (image below to illustrate).
In short, my scenario is:
...launch camera from button on home screen, then take a photo (currently want to use AVcapture framework) which once photo is taken/captured is sent to a UIImageView in a second view to crop and overlay text over the image, then submit to feed. If anyone can provide some sample code that would be very much appreciated.
Thank you very much for any feedback.

Hi Sethuraman,
This is not possible with current design of product as exploration views are combination of components from different information spaces.

Passing Image data through JNI?

Hello,
I am trying find the fastest way to pass image data from Java through JNI. Passing Java images through JNI seems to be a very common thing to do so I expect there's an oft-used approach. Can anyone give me a good explanation of this or point me to some references?
I need to pass the image data to a C++ function which operates on this data, writing the results to a destination buffer which goes back to Java and gets put back into an image.
Currently, I'm using BufferedImages and getRGB to get an int array from my source image, passing this through JNI along with another int array to be used as the destination buffer, then calling setRGB with my destination buffer after the JNI function returns. getRGB() preserves the alpha channel of png files, which is functionality I need. The problem with this approach is that getRGB is extremely slow. It can take up to two seconds with a large image on my 1.2 Ghz Athlon. It seems to be performing a copy of the entire source image's data. Maybe there is a way to decode a jpg or png directly into an int array?
-Aaron Dwyer

Here's how you could do it for TYPE_4BYTE_ABGR
BufferedImage img=new BufferedImage(13,10,BufferedImage.TYPE_4BYTE_ABGR);
img.setRGB(0,0,0xff0000);
img.setRGB(5,1,0x00ff00);
img.setRGB(1,1,0xcafebabe);
DataBuffer db=img.getRaster().getDataBuffer();
int dataType=db.getDataType();
if (dataType!=DataBuffer.TYPE_BYTE)
     throw new IllegalStateException("I can do it only for TYPE_BYTE");
int imgType=img.getType();
if (imgType!=BufferedImage.TYPE_4BYTE_ABGR)
     throw new IllegalStateException("I can do it only for TYPE_4BYTE_ABGR");
DataBufferByte dbi=(DataBufferByte)db;
byte[] array=dbi.getData();
SampleModel model=img.getSampleModel();
if (!(model instanceof PixelInterleavedSampleModel))
     throw new IllegalStateException("I can do it only for PixelInterleavedSampleModel");
PixelInterleavedSampleModel pisModel=(PixelInterleavedSampleModel)model;
if (pisModel.getPixelStride()!=4)
     throw new IllegalStateException("I can do it only for pixel stride of 4");
if (dbi.getNumBanks()!=1)
     throw new IllegalStateException("I can do it only for 1 band");
int scanlineBytes=pisModel.getScanlineStride();
// Access the green Pixel on Position 5,1
System.out.println( (int)array[5*4 + scanlineBytes] &0xff);     // Alpha
System.out.println( (int)array[5*4+1 + scanlineBytes] &0xff);     // Red
System.out.println( (int)array[5*4+2 + scanlineBytes] &0xff);     // Green
System.out.println( (int)array[5*4+3 + scanlineBytes] &0xff);     // Blue     I've added some checks to make sure we're accessing the data the right way.

Lion will only let you add documents to iCloud through iCloud.com, iCloud.com requires the iOS apps before you can use it.
Mountain Lion will let you add documents to iCloud from the iWork apps themselves, you don't then need the iOS apps before they can be opened on another Mac.

Pass Image to .dll

Hi,
I found quite a lot of topics on passing images to a .dll, however I didn't quite find an answer to my problem.
I want to pass a reference to an Image to a .dll.
The reference is of Type void* myImage in the LabView configure-dll, and when I create a .c file, it changes to uintptr_t* myImage.
If I pass that reference to the function
     void* IMAQ_STDCALL imaqImageToArray(const Image* image, Rect rect, int* columns, int* rows);
with the conversion (Image*)myImage, the function will always return a NULL-Pointer.
I know I can call all these function as VIs outside a dll, however I would really prefer calling them inside the .dll.
Some posts sounded as if this weren't possible, however I guess it has to be, as all the Vision-VIdo it.
Thanks for your ideas
Greetings
Solved!
Go to Solution.

Hi,
solved it myself, sorry to have bothered you!
For veryone who might run into the same problem:
Use the Image Datatype to Image Cluster.vi and pass the cluster to the .dll. It is in the folder National Instruments/LabViewX.x/vi.lib/vision/DatatypeCoversion
In the generated c-code, there will be a struct:
typedef struct {
    LStrHandle elt1;
    uint32_t elt2;
    } TD1;
where elt1 is the name of the picture and elt2 the address.
Say you've gt a function
void __declspec(dllexport) MyFunction(TD1 *ImageCluster, otherparameters)
you can now use the address elt2 to call tne imaq functions eg. like this:
Image *testImage;
testImage = (Image*) ImageCluster -> elt2;
uint8_t *ptr;
ptr = (uint8_t*) imaqImageToArray(testImage,imaqMakeRect(0,0,50,50),&x,&y);
Sorry again
Greetings

DNG Profiles with 32bit Tiff images

I am wondering what the correct procedure for creating these new 32bit HDR Tiff files in LR4.1 is, when you also want the image to have custom DNG profiles that were created from the XRite color checker. I know how to take 6 images, merge them to HDR in photoshop, save the image as a 32bit tiff. But how can I be sure my DNG profile went with the image over into PS. Also, do each of the images going into the HDR have to have the exact same whitebalance. Does lightroom secretly create tiff files before sending them to PS, or is it sending PS the RAW files to combine? Any help would be much appreciated! Thanks Rick

Hi Eeric, Having so many control points was in a effort to match the profile to the output of Capture NX, so that I could integrate all my workflow into Photoshop. I could not do without the use of as many control points because as you could see, so many hues of green were off. we should find a way around this problem. either like developing a set methodology of aproaching color adjustment or something else. I also suggest having a "Color Curve" probably something on the lines of the tone curve with input and output values of Hue.
I feel that there should also be a way to adjust the color range that each color control point can influence. That way there will not be a need to put too many control points close together.
