Image orientation with UIImageWriteToSavedPhotosAlbum

I'm trying to write an image from a graphics context to the photo library using UIImageWriteToSavedPhotosAlbum. Problem is that the context might be rotated, and I want the image rotation to translate over to the photo library.
I can create a UIImage from the context, but the imageOrientation property is read-only. Does anyone know of a way to somehow set or hint at the proper orientation for the photo library?
Thanks a lot!

The size of the catalogue is almost certainly not at play here.
FWIW, I recall seeing something like this once a long time ago on a Mac, possibly with Lr 3 beta, or Lr 2.x. It went away with a restart. It almost looks like a threading issue, where a thread is suspended or preempted and then is lost or disconnected from the main UI thread.
I recall you can just rotate the image again and it will right itself.
Adobe fist-line support seem to want to use the number of images in the catalogue as some sort of catch-all. The problem with this is that most of us can demonstrate that there is little correspondence with the number of image IDs in the database and many reported UI artefacts.
I'd keep raising this with them, and suggesting that the size of the catalogue is probably not at play here. As a tactic, you can ask what the maximum size of a catalogue should be, and if it is raw images or the number of changes to the images and virtual copies that is the problem, and if this can be verified by second- or third-line support.

Image Orientation/Rotation Problem in Lightroom 3.2 Final

This is a continuation of my previous post regarding this same problem in 3.2RC. It's still happening in the Final version of Lightroom 3.2.
THE PROBLEM
Image orientation is not working properly in Lightroom 3.2. This affects newly imported images and images that were already in my Lightroom database - and which have been in the database since Version 1.
Here's a screen capture showing the strange displays I'm seeing in Lightroom's grid mode:
Notice the odd angle of the image. When I use the Rotate Photo Left tool, the display looks like this sometimes. After a second or so, it will snap to either a vertical or horizontal orientation by itself but rarely gives me the 90-degree rotation this tool should give. The image may flip 90-degrees or 180-degrees, there's no way to tell.
When I view the image in Loupe view or on my second monitor, the orientation shown in Grid view does not match that displayed in Loupe Vew. For this particular image, Grid view currently shows it as correctly orientated as a horizontal while Loupe view shows it rotated 90-degrees to the right. Shouldn't they match?
BACKGROUND
I never had a problem with image orientation in any preveious version of Lightroom prior to Lightroom 3.2RC and 3.2 Final. So, it seems to be a bug in 3.2. I'm still using the same computer and video card I used with previous versions. My operating system is Windows 7 Home Premium. Both Windows and Lightroom are 64-bit.
HELP!
Is anyone else having this problem? How can I solve it?

Image files with large pixel dimensions display out of focus in a Bridge viewer?

I Create image files with pixel dimensions 2048x1365. When I display these files from Bridge on my Mac, either by pressing the space bar or in a slideshow, the images are out of focus. If I left click or click/hold and move the images slightly on screen they display in sharp focus. Unfortunately, although landscape-orientation images display correctly with no change in position or size, portrait-orientation files are enlarged and display with top and bottom off the screen. The pixel dimensions of my monitor are 2450x1600 so, yes, if portrait images are displayed at 100% they should display off screen, but this does not excuse the out of focus display of landscape files on this large screen. Nor does this explain why the portrait files are out of focus when they fit on screen. When the same files open in a Camera Raw window they are in focus. When they open in Photoshop at 100% the files are in focus.

Photo orientation with AppleTV

Hello all
I have been having some problems with photo orientation in AppleTV screen saver and in viewing the iPhoto library on AppleTV. I did all the usual things, restarted the Apple TV, restarted computer, etc. What was really strange was the photos I had changed rotation in iPhoto were all good. It was AppleTV which wasn't seeing them as 'corrected' images. What AppleTV was doing, was seeing the original photos, rather than the edited versions (the correctly oriented photos).
What I had to do was go to the original source of the photo. So I had to click on the photo, then go to File, see original file. The original file was still in the incorrect position. Once I opened this in preview and corrected it, it seemed to work. Will keep you posted. What is also interesting to note is that AppleTV was having problems with the original picture files of photos taken with a camera, rather than with the iPhone. There seems to be a bug here about how the AppleTV sees original and corrected files when the photos are taken with a digital camera.
Keen to know what others have found.
Happy AppleTV travels everyone.

Updating the information regarding photo orientation with AppleTV screen saver.
Clear instructions: Click on photo in iPhoto, then go to File, choose 'Reveal in Finder', select 'Original File'. A window opens up where the original photo file is held. Open the photo in Preview. Rotate photo as needed. Close and save. You are done. Restart your AppleTV and turn your photos on and off to share in iTunes. Ta Da, it all works and it's very easy.
Hope this is helpful.

Can you lock the background image orientation?

Hello all
Is there a way to lock the image orientation? When I turn the iPad, I want the apps to rotate, but I want the background image to stay portrait.
If not, is there someplace i can suggest the feature?
Thanks!

No. It will orient along with your view. You can post feedback here: http://www.apple.com/feedback/

Indicated Image Orientation is Incorrect

Hi all:
Aperture 2.1.1 has begun to incorrectly tag images in the portrait orientation as “Landscape,” even though the images were correctly oriented as portrait during import and when viewing them in the Browser or Full screen mode. Doesn’t matter which camera (Nikon D80, Canon Powershot SD600 or Panasonic DMC-TZ1) I import from.
Additionally, when viewing the incorrectly tagged images in the Finder window, set to column view, portrait-oriented images correctly oriented in Aperture are incorrectly oriented as landscape in the Finder window. They also open as landscape-oriented images in Preview. If I correctly rotate the image in Preview, then save the file, the Finder correctly displays the image, but the thumbnail in Aperture becomes corrupted: The image orientation in the Browser window remains as portrait, but the image preview has rotated 90 degrees.
Can’t tell if this occurred since upgrading to Aperture 2.1.1 or Mac OS 10.5.5. Any ideas?

Thanks for the tip. I did exactly what you suggested and ended up with over 2000 extra versions (sometimes up to six) of my files, some with strangely cropped previews, and files long since deleted. All these extra versions did not include any metadata I added (i.e., keywords, description, byline, city, state, etc.). In some cases the file name reverted back to the original one assigned by the camera(s).
Meanwhile, rebuilding the database did not solve the incorrect orientation tag issue. All my images are referenced masters. No masters in my database are stored in the Aperture library.
Thanks for any advice out there.

CameraRoll & CameraUI image orientation

Hi,
I am trying to read the Orientation tag in EXIF image data grabbed with CameraRoll or CameraRollUI using AIR 3.6 on iOS 6.1
To achieve this, I use this library coded by Christian Cantrell :
http://blogs.adobe.com/cantrell/archives/2011/10/parsing-exif-data-from-images-on-mobile-d evices.html
Unfortunantly, it raises an error when I try to parse the Byterray containing the EXIF data :
var exifInfo:ExifInfo = new ExifInfo( eb );
TypeError: Error #1034: Type Coercion failed: cannot convert "<tags level="0th IFD TIFF Tags">
<tag tag_name="Image width" field_name="ImageWidth" id="0x0100" compressed="J">
    <uncompressed chunky="M" planar="M" ycc="M" />
... INSERT BIG CHUNK OF XML HERE ...
</tags>" to XML.
          at jp.shichiseki.exif::ExifInfo/readIFDs()[/Users/***/Google Drive/AS3/libs/jp/shichiseki/exif/ExifInfo.as:100]
          at jp.shichiseki.exif::ExifInfo()[/Users/***/Google Drive/AS3/libs/jp/shichiseki/exif/ExifInfo.as:63]
It seems that Air can't cast the data into XML, but it's kind of crazy because I am able to see all the data in the error text (I purposedly truncated it here for not flooding this post) and it's XML valid. I had a look into the ExifInfo class, but it's hard to see where the error comes from.
I really need to get access to these data, since it's the only way to determine image orientation in iOS. Or is there any native extention thaht I could use to achieve this ?
Any advice will be welcome as I am stuck on a project for a client because of this.
Thank you all !

Hello Frog,
a very (very) dirty solution could be :
- use a try...catch...finally block to prevent the error raising
- in the catch block, parse the error message to get your orientation value (String method, regexp...)
[code]
var myExifData:XML;
try {
     // try to get the exif data
     var exifInfo:ExifInfo = new ExifInfo( eb );
} catch(err:Error) {
     // fails, but maybe I can get the exif info in the error message...
     myExifData = parseExifError(err.message); // parse the error message to get your orientation info...
} finally {
    do what I have to do with my image : rotate, scale....
[/code]
BTW, PhoneGap is perfectly able to get orientation of an image from the camera roll. So there IS a solution somewhere.
Maybe you could try to make a native extension ? It's not so hard for little things like that...
My 2 cents

Image Orientation in Blog and Blog Summary

Inserted a picture into a blog entry and rotated it 90 deg.
In the blog summary, on the summaries page, the image reverts to its original orientation.
Can't see a way to change the image orientation on the summary page, which would be undesirable anyway - don't want to have to edit two pages for every entry.
Has anyone experienced this problem?
Are there any solutions?
Thanks

I played around with the orientation manually, and found that if I change the orientation, the image would be correctly "orientated' in the lower part of the split viewer, but the actual image would be off by 90 degrees. I then reoriented the image back (sideways view in the bottom file-strip) and the large image would display correctly again, and, the bottom image corrected itself to the normal orientation. So, by changing each sideways image 90 degrees once and then back again, seems to "fix' the issue. Still not sure how I applied this feature.

Facetime image orientation?

I held a facetime chat with a friend and was completely unable to cause both phones to properly display horizontal oriented images. Each person saw the other horizontal image as a belt-line horizontal you would see on a vertically oriented iPhone.
With both vertical-no problem.
The ads clearly show several examples of both ends of the conversation captured in horizontal orientation, but nothing we could do would convince the phones to behave this way.
Any clues?

Found it!
After searching the iPhone docs several times with no success, an article on the internet pointed to the easy Image Orientation Lock/Unlock control.
For others with this "issue", it's found by double clicking the Home button on the iPhone, then flicking the line of apps to the right. Most/many of us are familiar with flicking this to the left to search back in our app usage, but when you flick to the right, there's a set of iconic controls, including the circle around a lock symbol.
All well now. Thanques to all.

[solved] Image orientation issue

Hello,
I have a problem with image orientation.
I am using Arch64 and KDE 4.4.5 from Arch.
When I look at my pictures in digikam (1.3.0) or gwenview, portrait pictures are displayed fine. If I send them with thunderbird, portrait images are displayed with landscape orientation.
The only workaround I found is to rotate twice the image with digikam (once on the right and once on the left to set it back to previous orientation).
I have noticed that EXIF information change...does anyone have the same issue and knows what is the cause of it ?
before, orientation is "droit, haut" = "right, top"
after, orientation is "haut, gauche" = "top, left" and width and heigth size is set...
regards

Digital cameras create images that aren't rotated as such -- as plain images they're always in landscape format. If your camera has an orientation sensor, it will merely hint at the intended orientation by setting the exif orientation value in the jpeg file (instead of really rotating the image and creating a jpeg with a portrait format).
Not all programs interpret all exif data. Programs that don't interpret the exif orientation (as thunderbird seems to do it) will display the image as it is (always in landscape), while others (like digikam) use the exif data to decide on how to rotate the image for display. So digikam is just smart enough to show the image in it's "logical" portrait format while it's "physically" remains in landscape format.
To make a real portrait jpeg, you have to really rotate it and adjust the exif orientation accordingly, which is what effectively happens if you use digikam in the way you describe it. So that's not a workaround, but required to make sure that all programs display the images in the desired format, and not just those that are smart enough to honor the exif orientation.
See the jpegexiforient and jpegautotran programs for an explanation and an alternative way to rotate images based on their exif orientation value.

Photoshop-When opening image without tab view, image opens with only a portion in view

I having an issue with CC.
When electing in the preferences to not open image in Tabs. The images open with only about 25% of the image area showing. Forcing me to (command) 0 for full to screen preview or (command) +/- to see the image.
I am not talking about seeing the image at 100% resolution just the entire image within the floating window without having to command before view.
Sidenote: Adobe Customer Service is all based in India. I spent 4 hours on the phone only to hear that this is that way photoshop works.
There would be no logical explanation for this. Since the first version of Photoshop this has not been the case.
I think this should be called view porn with wife in the room mode. Other than that I see no point.
Can anyone help?

Image processing with imaq vision with 2 webcams on the same computer

Hi,
I'm currently trying to set up 2 usb webcams (logitech quickcam for notebooks pro). I want to be able to have them both run simultaneously and do some image processing with the images that I get from both cameras with labview and imaq vision.
As of right now, I'm having trouble getting both cameras to run at the same time. Any help would be gladly appreciated. Thanks.

The USB IMAQ driver will not support running 2 USB cameras at a time (I believe it is a limitation of the DirectShow interface). You could open one camera, acuqire an image, close the reference to that camera and then do the same for the second camera.
If you need simultaneous acquisition, look at possibly moving to 1394 cameras or analog cameras.

How Do You Make an Image Flow with the Text?

Hello all,
I am using CS4 InDesign on Windows Vista. I am fairly new to Indesign but try to do my research and homework well before asking what I hope is not a really dumb question.
I am writing a book of approx. 350 pages that is an illustrated encyclopedia of 156 plants and their oils.
Each 2 page spread is a single entry for a plant. The graphics frames on each spread are identical in size, position and styles for a consistent look throughout the document.As you can see (hopefully) each page is a single column. See screenshot below
In order to overcome my first problem of positioning and sizing the graphics frames uniformly, I created the master pages with the graphics placeholders sized, positioned and formatted to my liking. This worked wonderfully and I placed all of my 300+ graphics by simply over riding each frame.
Then in my editing I decided to add another 2 page spread somewhere in the middle of this fairly large document.
What a NIGHTMARE. The text predictably shifted but now ALL of my graphics were no longer associated with the corresponding text! Arrrgghhh.I had not anticipated this behavior (used MS Word for 15 years) or I would have done something different.
3 hours later I finished re -"placing" the images associated with the correct text.
I researched the help file and found out about the neccessity of anchoring graphics to text. I have read through the threads in this forum, followed links to "indesignsecrets.com/make-an-image-flow-with-the-text" and " Working with anchored objects by Anne Marie Concepcion"
My concerns are this.
An inline graphic places the graphic back onto your text layer for some reason ( Previously my graphics each had their own layer)
Not wanting to start (again) from scratch with my graphics I converted them to inline/custom anchored objects.
But to select then cut then paste every pre existing graphic to anchor it inline seems to be cumbersome and counter intuitive although the top smaller graphic did position well and the text seemed to wrap ok.
When I placed the larger bottom graphic on the left facing page using custom positioning I was not able to get the text to wrap at all.( The in line anchoring did not seem to allow for positioning on anything but the 'Y' axis).
It seems that there would be a simpler way to place text and graphics where you want them and have them associate and flow together (or not) when you want them to and have text wrap easily around an anchored object without keyboard gymnastics. It would seem that the concept of a certain graphic being associated or linked with certain text would not be an unusual concept in desktop publishing.
Am I missing something?
Can you place an anchored graphics frame on the master page with your desired options?
How would this be done if possible?
Is there any other way (i.e grouping) to keep graphics associated with the desired text so that it flows together if extra pages are added?
Is the fact that my graphics frames are on my master pages responsible for my text wrap difficulty? (I have text wrap enabled on my master pages)
Are there any settings, redundant or otherwise, I need to be aware of?
Thank you in advance for any suggestions or directions
L.N.

Hello Again,
Thank You Bob but I am still a little fuzzy on this. I have already created object styles for the graphics frames. For instance the small graphic underneath the heading (Its a drop of oil) has an object style applied. Now I checked and it has the anchored object options checked in the style dialog box. When I reapply the style to the next similar graphics nothing happens. It is still not anchored. Do I need to create a new style based on "nothing" add my effects plus the anchoring options? Basically start over. If thats what I need to do thats OK. As to your instruction that object styles could accomodate this anchoring thing...thats what I thought too but somehow I can't get it to work. See object style dialog box screenshot below:
For the larger graphic on the bottom of the left facing page. I still cannot get any text to wrap. In the screenshot example the text describing this particular plant doesn't go to the bottom of the page so the wrapping issue on this page is moot. However I have some entries where the body of the description is more involved and does go to the bottom of the page and the text WOULD need to wrap around the plant (larger ) graphic.
Hi there Harb, Yes I found out early on that object styles can't apply size (that would be on my wish list for sure) That is why I found that creating my graphics frames on the master page with the correct size, effects and positioning tickled me so much. Can you believe I originally went through and MANUALLY resized and repositioned each and every 300+ graphics in this book but it still wasn't right. I'm nothing if not persistent. (Now if I could just get my grown sons to pick up their socks!)
Anyway the master page graphics frames idea would be perfect if I could get the images to anchor in their respective spots on the master page as well.
For your second suggestion. I am not clear about why I would need to break the threads of each spread so that each spread is a seperate article. Is the threading issue the thing that is causing my text to move on leaving their associated graphics behind? If so how do I go about doing this?
So to recap:
1. I need to know if I can modify my object style or recreate from scratch with the anchoring option (as I said it didn't work)
2. Can't get text to wrap around the Custom anchored graphic at bottom of page at all
3. Im not clear on the breaking the threading on the spreads
I am willing to go back through and start from scratch (new master pages, styles etc ) if neccesary. This book is the culmination of 7 years of research and artwork.Basically the project is DONE. Now if I can just format it correctly.
I can't thank you both enough for your time, suggestions, expertise and patience.
Thanks again

Creating a .jpg image from with in the J2ME app

Hi,
I want to send a document to the printer over bluetooth to print.
For that I searched on net, but couldn't find any APIs supported by J2ME to print it. I also found a link http://www.hcilab.org/documents/tutorials/Brother/ where I found that I can send the data by creating an image and then writing data (text or image ) in to it, and then sending that image to print.
Image img = Image.createImage(816, 40);
Graphics g = img.getGraphics();
g.setColor(0, 0, 0);
g.setFont(Font.getFont(Font.FACE_PROPORTIONAL, Font.STYLE_BOLD,Font.SIZE_LARGE));
g.drawString("Printing test from "
                         + System.getProperty("microedition.platform") + " on "
                         + new Date(), 10, 10, 0);
driver.print(img, btAddr);This code is working fine on this printer.
I am using HP 460cb printer, and I tried the same thing, but am not getting any results. Can any one of you tell me what mistake am I making.
                Image blankImage = Image.createImage(SpotBilling.MAX_IMG_WIDTH, SpotBilling.MAX_IMG_HEIGHT);
                Graphics g = blankImage.getGraphics();
                g.setColor(0,0,0);
                g.setFont(Font.getFont(Font.FACE_PROPORTIONAL, Font.STYLE_PLAIN, Font.SIZE_SMALL));
                g.drawString("Printing test on Wednesday - 18th Jan, 2006", 10, 50, Graphics.TOP|Graphics.LEFT);
                g.drawImage(imgTest, 60, 150, Graphics.HCENTER | Graphics.VCENTER);
                int width = blankImage.getWidth();
                int height = blankImage.getHeight();
                int y = 0;
                os.write(CMD_UNIVERSAL_EXIT);
                for(int i = 1; i<=height; i++){
                         blankImage.getRGB(temp, 0, width, 0, y, width, 1);
                         byte[] pixels = new byte[width];
                         for (int x = 0; x < temp.length; x++) {
                              pixels[x] = (byte) ((((temp[x] & 0x00FF0000) >> 16)
                                   + ((temp[x] & 0x0000FF00) >> 8) + (temp[x] & 0x000000FF)) / 3);
                         // Transfer Raster Graphics
                         os.write(TRANSFER_RASTER_DATA);
                         byte[] len = numToDecimal(pixels.length);
                         os.write(len);
                         os.write(DATA);
                         os.write(pixels);
                         y++;
                    }I have another query, if I can not do this. Is there any way I can create a .jpg image from with in the J2ME application.
I have some text and an image that I get by invoking camera from the code and then capturing a picture. I need to combine them both, and then send it to the printer.
If there is any way, I can convert this blankImage mentioned above (containing both text and Image), please provide me the solution.
Any document or any source code is appreciated.

                     img = Image.createImage(50, 60);
     protected void paint(Graphics g){

          graph.fillArc(0,0,10,10,0, 360);
     }Now I want to create a .jpg image of this img image(Mutable image).
What I am doing is that,
1. I am converting this image in to int array, using getRGB() method.
2. Then I am converting int array in to byte array.
3. And then I am opening a file(extension is .jpg)
4. Then I am sending this byte array in to the file which is .jpg
The .jpg file is getting created, but the data in it is very absurd, like yyyyyyyyyyyyyyyyyyyyyyyy.
Please help me in this matter.

Photos in my from my iPhone have same numbering as photos from my dig camera. They all go into iPhoto fine but when I backup to my ext hard drive it will only save one with the name IMG 1002 and I have two separate images both with that name. Help?

Photos in my from my iPhone have the same numbering as photos from my digital camera. They all go into iPhoto fine but when I backup to my ext hard drive it will only save one with the name IMG 1002 and I have two separate images both with that name. How do I get them all to save on my ext hard drive and hope do I prevent this numbering overlap in the future? I'm really hoping I don't have to go through and manually rename every single picture. Thanks.

How are you backing up the photos? The best way is to backup the library itself as that will preserve your organizational efforts as well as all metadata like keywords, titles, faces, places, books, etc.
You can use a backup application that does incremental backups. Thus only the first backup is a full one and subsequent backups just copy those files that are new or changed. I use Synk Pro. The lower cost version, Synk, will do the same job. Other similar apps can be found at MacUpdate.com.
OR: upload your camera to a folder on the Desktop. There you can rename the files to something that is more informative than just the file name. I use the date (international format) along with a brief desc: 2007-1-20-adian1stbday-001.jpg. File renaming apps can also be found at MacUpdate.com. Also you can give the folder an informatve name which will become the Event name when you import the folder of photos into iPhoto.
