Adding private IFD and IFD pointer to TIFF image metadata with jai-imageio

Hi,
I searched on the Internet for the answer but I was only able to find this post from the old forum/mailing list:
http://www.java.net/node/698039
The question in the post went unanswered and I am in a very similar situation now. To re-iterate the questions:
* How to merge the metadata of the private IFD into the root IFD?
* What to populate for the offset parameter in the private IFD pointer tag (the parent tag)?
I am modeling it after the EXIF tag sets, very similar to what is in the above link.
Any help would be greatly appreciated ...
Thanks,
Dennis

Hi Jim,
Thank you for posting in the MSDN forum.
You know that this forum is to discuss the VS IDE issue,
I am afraid that the issue is out of support of
Visual Studio General Forum
To help you find the correct forum, would you mind letting us know more information about this issue? Which kind of app do you want to develop, a WPF app or others?
If it is the WPF app, maybe this forum would be better for it:
http://social.msdn.microsoft.com/Forums/vstudio/en-US/home?forum=wpf
Thanks for your understanding.

Recovery and Black Point on JPEG images

I'm not a big fan of trying to do much editing on JPEG images aside from non-exposure/white balance type stuff. I'll crop and straighten, etc.
My question pertains to (for those in the know) applying slight Recovery and Black Point correction to images that aren't shot in RAW format. A) will applying these slight changes having any effect (hopefully a positive one) on the images? B) if not, will it indeed have a negative effect?
Thanks for your time and expertise.

Jim,
Thanks for chiming in on a topic where I didn't expect to get many replies. All of your comments are well appreciated. I was basically asking because I was under the impression that unless your master is in RAW format, making adjustments to exposure, contrast and even recovery and black point would not do much and could even be detrimental to things such as skin tone, etc. I like to shoot in RAW for the reason of being able to have more fine control to adjustments, but for everyday shots and portraits I don't always go to RAW format since a lot of the time I have trouble getting the shot right with the manual controls. I also don't want the large RAW files for every shot that I take. Still, a lot of JPEG's need adjustments, even if just minor tweaks. The tweaks I make look fine on the screen, but I wasn't sure if they would look okay when printed out and I didn't want to spend countless hours making adjustments and spend (waste) money on prints that weren't going to come out good.
Anyway, that is the background to my thinking in making this post. Thanks again for chiming in.

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.

Java returning incorrect values for width and height of a Tiff image

I have some TIFF images (sorry, I cannot post them b/c of there confidential nature) that are returning the incorrect values for the width and height. I am using Image.getWidth(null) and have tried the relevant methods from BufferedImage. When I open the same files in external viewers (Irfanview, MS Office Document Imaging) they look fine and report the "correct" dimensions. When I re-save the files, my code works fine. Obviously, there is something wrong with the files, but why would the Java code fail and not the external viewers? Is there some way I can detect file problems?
Here is the code, the relevant section is in the print() routine.

Figured it out. The files have a different vertical and horizontal resolutions. In this case the horizontal resolution is 200 DPI and the vertical is 100 DPI. The imgage width and height values are based on those resolution values. I wrote a section of code to take care of the problem (at least for TIFF 6.0)
 private void setPageSize(int pageNum) throws IOException
 IIOMetadata imageMetadata = _reader.getImageMetadata(pageNum);
 //Get the IFD (Image File Directory) which is the root of all the tags
 //for this image. From here we can get all the tags in the image.
 TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
 double xPixles = ifd.getTIFFField(256).getAsDouble(0);
 double yPixles = ifd.getTIFFField(257).getAsDouble(0);
 double xRes = ifd.getTIFFField(282).getAsDouble(0);
 double yres = ifd.getTIFFField(283).getAsDouble(0);
 int resUnits = ifd.getTIFFField(296).getAsInt(0);
 double imageWidth = xPixles / xRes;
 double imageHeight = yPixles / yres;
 //if units are in CM convert ot inches
 if (resUnits == 3)
 imageWidth = imageWidth * 0.3937;
 imageHeight = imageHeight * 0.3937;
 //convert to pixles in 72 DPI
 imageWidth = imageWidth * 72;
 imageHeight = imageHeight * 72;
 setImgWidth((int) Math.round(imageWidth));
 setImgHeight((int) Math.round(imageHeight));
 setImgAspectRatio(imageWidth / imageHeight);
 }

TIFF images, Working with Color Palette.

I would like to read in a tiff image, change some of the color values and then write out the new file. Is this possible?
Thanks.

Ah dude, that's super-easy.
In JAI there is a call to convert to grayscale, but here is how to remove the red from every pixel in an image:
Assuming you have a BufferedImage called image...
// get image dimensions
int width = image.getWidth();
int height = image.getHeight();
// create pixel array
int pixels = new int[width*height];
// copy data from image into pixel array
pixels = image.getRGB(0,0,width,height,pixels,0,width);
// remove red from entire image
 for (int x=0; x<width; x++)
 for (int y=0; y<height; y++)
 int index = x+y*width;
 int pixel = pixels[index];
 int red = (pixel & 0xff0000) >> 16; // don't really need this, but whatever
 int green = (pixel & 0xff00) >> 8;
 int blue = (pixel & 0xff);
 // Check intensity of pixel for each band
 if (red > tolerance || green > tolerance || blue > tolerance)
 // rebuild pixel with only green and blue values
 pixels[x+y*width] = ( 0xff000000 | (0 << 16) | (green << 8) | blue);
 }There you go!

Open Tiff image failed with imageio package

I'm trying to open tiff files with javax.imageio.ImageReader. When openning the image file, "bad.TIF" with the following codes, I got an error. However, I can open the image with "Windows Picture and Fax Viewer" (WPFV). After I opened/saved as File "good.TIF" with WPFX, I can open the image with the progarm. Would someone please help?

Can you upload the bad tiff to an [image hosting site|http://www.imagehosting.com/]?
In general, when you set the input stream on a reader for a second time, it's a good idea to call reset.
errorPos = 2;
file = new File(testFile2);
tiffStream = ImageIO.createImageInputStream(file);
reader.reset(); <----- this line
reader.setInput(tiffStream);
tiffImage = reader.readAll(0, reader.getDefaultReadParam());I don't think that's the source of your problems though. You can add an IIOReadUpdateListener and a IIOReadWarningListener to the reader to see just how far it gets just before the exception is thrown. It may very well just be a badly saved tiff, or it could be a tiff image reader bug.

Pivot point in image rotation with JAI...

I'm using JAI to rotate some images...
but it doesnt seem to rotate around the center of the image..
here is my codes..
float xOrigin = ((float)src.getWidth())/2;
float yOrigin = ((float)src.getHeight())/2;
float angle = (float)v * (float)(Math.PI/180.0F);
Interpolation interp = Interpolation.getInstance(Interpolation.INTERP_BICUBIC);
ParameterBlock params = new ParameterBlock();
params.addSource(src);
params.add(xOrigin);
params.add(yOrigin);
params.add(angle); // rotation angle
params.add(interp); // interpolation method
des = JAI.create("rotate", params);
displayImage(des);
note: src and des is defined as PlanarImage.
any clues why the center point isn't height/2 and width/2??
thx

It seems that on problem with the code, I use same code when I rotate the image. How do you display the image? maybe problem is there, after the ratation, the origin of the image changes, if your display method can not handle this, you may not display it properly.

How to Render a TIFF image sequence with After Effects or Premiere

So I shot a timelapse in RAW using my D5200. Developed the images, imported into after effects to make a composition at 1080p 24fps, the clip is 15 seconds long. Then I rendered the clips a few ways and none of them are what I want:
I used the H.264 first, its just pixelated and blocky, doesn't retain a smooth resolution. H.264 output an MP4 that was 6.5 MB.
Then I tried lossless and it output an AVI which is awesome resolution but the file is 2 gigs! Not even VLC media player will play it smoothly without buffering.
Last I tried H.264 BluRay which output an M4V file which is 45 MB and I can't get it to play.
So now I'm here asking you all what the way to go is. When I download films, I will aim for a 1-2 gig 720p or 1080p file on roughly 2hr films. The resolution is great, the audio is great and the file like I said is only 1.5gigs average. So what are the rendering settings I should be using to get a file like this? Should I be importing it into Premiere Pro first or what?
-Thanks
Bruno
For Reference, here was my workflow:
I generally followed an Adorama Rich Harrington Time-Lapse youtube video on workflow which was:
Developed the Raw files in Camera Raw
Used the Image Processor to create the Tif files
Imported into After Effects as a TIF sequence
Interpreted the sequence as 24fps
Changed the Composition settings to 1080p 24fps
Then did the rendering as detailed above

1. You don't need to export your TIFF sequence so as to import it into After Effects, you can import RAW image sequence into After Effects directly. Camera RAW will start automatically on importing. What is more, you will be able to change your Camera RAW settings at any time you want inside your AE project: in Project panel select your RAW image sequence, right-click, choose Interpret Footage -> Main... In the dialog box click More Options... button (at bottom left), and Camera RAW opens.
2. Do NOT export to H.264 out of After Effects directly. If you need to export your composition to H.264, export it out of Adobe Media Encoder. Start from HDTV preset. If your goal is to upload your media file on e.g. YouTube, done. If you want to play it back on your computer, but your mediaplayer can't playback it in real time, start to decrease bitrate settings. Keep in mind that modern AVCHD cameras shoot with 28 Mbps, first AVCHD camcorders were shooting with 17 Mbps, YouTube preset in Adobe Media Encoder sets bitrate to 10 Mbps, Vimeo preset - to 8 Mbps.
Choose VBR, 2 Pass so as to benefit from better quality out of smaller file size.
See this The Video Road blogpost on Understanding Colour Processing and benefits of Render at Maximum Depth option.
3. If you're planning to use your After Effects composition in Premiere Pro project, you can use Adobe Dynamic Link. If your After Effects composition is quite complex, render a Digital Intermediate out of After Effects and import it into Premiere Pro. See this discissuon in AE Forum on some production codecs comparison.
P.S. See also this FAQ: What are the best export settings? entry.

How to load compressed tiff image formats with JIMI

this method
Image image=image = Jimi.getImage(imgResource);returns incorrect Image width & height (-1) for TIFF compressed formats.
is there any jimi example showing how to properly load the tiff compressed image ?
thanks.

Wild guess: how old is JIMI technology? Has it been
kept uptodate, or has
it been abandoned? And is LZW compression in TIFF
format a more recent feature?yes i checked jimi docs and here is what they say :
TIFF
* Bi-level / Greyscale / Palette / True Color images
* Uncompressed images
* CCITT compressed Bi-level images with CCITT RLE, CCITT Group 3 1D Fax, CCITT Group 3 2D Fax, CCITT Group 4 Fax, CCITT Class F Fax
* Packbits compressed images
* LZW Compressed images
* Tiled TIFF files
* Handles all values of Orientation
* TIFF / JPG compression variant
* any color space except RGB
* True Color images not of Red/Green/Blue format

Private dictionaries and Namespaces

Private dictionaries and Namespaces
We ran into an issue with some email templates in converting from RC2006 to RC2008.3 where Namespace values from Private service dictionaries were not populating correctly in RC2008.
In the upgrade process from RC2006, any private dictionaries are converted to actual dictionaries. They are created in the Dictionary Group UPGD: PRIVATE DICTIONARIES and the dictionary name is based on the service name: PRIV_ServiceA.
What I found as we were testing is that the Namespace parameters in Email templates (and, presumably, conditional statements and other places) no longer worked.
The reason is that the Namespace Parameter for a private dictionary did not use a dictionary name, e.g. #SERVICE.DATA.Field1#. In order for the RC2008 version to work, we had to add dictionary references: #SERVICE.DATA.PRIV_ServiceA.Field1#.

Hey M.VAL,
Thanks for the question. If your dictionary is not available after updating your device, you may need to redownload it:

I want the smilie to show up in the "hole" and where it is positioned now makes it show up there.

Hi,
I am new to MSDN and require some help on dealing with TIFF images.
How do i extract the values from TIFF images, edit their values, and resave them as TIFF images?
I saw the MSDN information on "How to: Encode and Decode a TIFF image".
But still have the following issues.
1)Image^ myImage = gcnew Image(); --> error: Image is ambiguous. I am apparently missing some includes or namespace, but i can find the System::Windows::Image namespace.
2)How do i extract the grayscale values from the TIFF images? What variables are they being stored in?
Thanks!

Editing metadata in a TIFF image

Hi everyone,
I'm trying to edit TIFF image metadata using ImageIO v1.1 APIs, but something goes wrong...
For a TIFFImageWriter I get the following results:
writer.canInsertEmpty = true
writer.canInsertImage = true
writer.canRemoveImage = false
writer.canReplaceImageMetadata = false
writer.canReplacePixels = true
writer.canReplaceStreamMetadata = false
writer.canWriteEmpty = true
writer.canWriteRasters = false
writer.canWriteSequence = trueSo editing metadata with writer.replaceImageMetadata is not possible (I verified this, an exception is thrown). I thought I could remove an entire image and reinsert it with new metadata, but as you can see writer.removeImage is unavailable, too.
How can I edit a TIFF image without rewriting it to a totally new image file?
Any help will be appreciated,
Giuseppe

Huh... I am in bitmap... OK, how would I go about changing to RGB? Not a complete novice, but never had a similar problem before.

How to display TIFF images?

Hello all.
My web application needs tiff images viewer with a very primitive functionality like zoom. I'm a new in working with graphics and it seems like java.awt.image package doesn't support TIFF images format. From searching this forum I understood there are 3 party products like JAI to work with those images.
Can somebody send me an example of how to read and display those images with zooming option; and/or how to convert from tiff to GIF/JPG formats (which also can be a solution for me).
If somebody has a ready applet that implements the required functionality and can share it with me, I would appreciate it very much.
Email: [email protected]
Thanks in advance.

I am also looking for Tiff Image zooming functionality. Please through your ideas or suggestions. I will appreciate your advises. If anyone has developed API, Please let me know, I am ready to look in to it. I will appreciate your quick response.

Activex image viewers to view multipage tiff images

I have some multipage tiff images which i need to show up on forms. but the image item doesn't support multipage images. does any body know any other activex components which can replace image item and can display multipage tiff images. or is there any tricky way to show multipage images on oracle forms. thanks.

where are your images in? file system or table?
do you want to show one image at a time and navigate to another one or show multiple images at one time?
in table, you may use query and next_record; in file system, you may read next file by read_image_file() eatch time clicking a button.
