Tiff Image and Flex

I would to know if there is a way to open tiff files from a
flex application. Have already tried image control but it doesn't
seem to be able to handle them. Any solution?
Thx in advance.

Correction, PDF is not required to be geneated, but displayed.

MIME Content Type in HTTP Headers - They don't exist for TIFF images

Hello,
I think this may be a bug...
In an effort to stop client browsers from attempting to render TIF images served up from UCM 11g, I would like to change the MIME Typte to: application/octet-stream
Supremely, a browser would see this in the HTTP header and simply provide the "OPEN or SAVE" dialog.
Seems easy enough - from the UCM Configuration Manager, I can set/edit all the mime types I want. I did set .tiff and .tif to application/octet-stream. Apparently Weblogic does NOT honor these settings.
When I click on a PDF file, I get: application/pdf
When I click on a TXT file, I get: text/plain
When I click on a TIF file, I get: NOTHING - no mime type specified in the HTTP header at all.
Does anybody know where in the stack of Weblogic/UCM 11g that mime types are set? Does anybody know why I'm not seeing ANY mime type when I click on a tif?
Please let me know.
Thanks!
JDM

Yeah, that does seem a bit unwieldy. Try the following instead:
Navigate to the "<Middleware_home>/user_projects/domains/<yourdomain>/config/" directory and there create the following file :
mimemappings.properties
In this file add the below mapping :
tiff=application/octet-stream
Save the changes , restart UCM server and then test to see if the issue still shows up .

Color Changed when reading a Tiff Image

I have created a ImageIcon of a tiff image by using the following code. but when reading some images the color is Mis-Matching
BufferedImage bufImage = ImageIO.read( <tiff file path> );
JLabel jLabel= new JLabel(new ImageIcon(bufImage));whats the reason for this?.. anybody send me the code snippet to read the tiff image in its original color.. please..

Thanks for the reply.
When I render a tiff format image, I have a choice to either render with a alpha or not. I pick with alpha.
In CS2 Photoshop when I would open that tiff file, my image would come up and I would be able to see the whole image I rendered. The alpha would be in the channel tab where I would make active and apply to my image if I wanted to.
Now in CS5 when I open that same tiff file my image opens up with the alpha applied already. What I mean by applied is my background is gone or transparent. I have no other layer to turn on. Just my image with no background. Also in the channel tab I have no alpha I would have to create one from the original image.
I hope this explains my issue better, if not let me know I'll have to do some screen shot for you.

How export report SSRS to TIFF image programticlly

dear all,
I have in my application reports called from my page to the reporting service of SQL-Server.
I want in my web-form (with programming) to export this report to TIFF image ...

You can use LocalReport.Render method to export into TIFF format. Check
link. In the format parameter type it as "Image" and the file extension retain it to TIFF.

Display *.bmp images or *.tiff images

Hi All,
Need help in displaying *.bmp / *.tiff images at runtime.
I am working in an application where the user may upload
images (jsp) in any format (jpg/gif/png/bmp/tif) and I need to
display these images from an user interface built in Flex with zoom
effects. I am able to display jpg/gif/png using the standard Image
control with zoom but unable to display the bmp and tiff files.
Is there any way to display tiff and bmp files?
Please help.
Regards,
Paromita

All is well now. I used the Revo Uninstaller (www.revouninstaller.com) which scoured the registry and deleted dozens of left-behind pieces, then I reinstalled off the disk using all the default settings.

2 CCITT T.6 tiff images

Hello,
I am trying to display a CCITT T.6 tiff image file (say t1) in the browser (IE8). The file size is 15kb (I can see that it has II* bytes in the header). It does not display (all I see is a red x in place of the image). Then I open up the file using ms-paint, save it as t2 (this file has M* in it). Now the file size close to 2 MB. If I look at the file properties of t2, it still says CCITT T.6 however, this file displays ok in the browser.
When I say display, using jdeveloper to render it in a table region in an oaf page using servelet. Servelet reads 't1' from a blob cloumn.
What could be the potentiall difference between the 2 files?
Assuming that the compression is causing the t1 to not display, how would I un-compress the file? Can any one provide a sample code?
I am a java newbie, image file newbie trying to learn as much as I can. pls. help
Thanks,

JMF doesn't have the ability to do this, so you'd need to look elsewhere for help on doing this.
Perhaps the "Java Programming" forum would be more appropriate... or Google.

A generic error occurred in GDI+ while assing tiff image file to Bitmap and Image

Hi,
I am getting "A generic error occurred in GDI+" error while reading the tiff image file to Bitmap or Image.
Below is my sample code.
string filePath=@"c:\Images\sample.tif";
Bitmap bmp=new Bitmap(filePath); // here getting exception
int totalpages=bmp.GetFrameCount(.....);
etc......
I tried using Bitmap.FromFile() and also from FromStream() even for Image also but there is no use.
Moreover i m having full permissions for the file path and the tiff file is having multiple pages.
Can anyone help me to solve this issue please.
Thanks & Regards,
Kishore

Make sure that the Tif file is valid (can other software open it)? If you are able to save a Tif using GDI+, try saving that Tif, then opening it. Part of me wonders if there is something about that specific Tif that GDI+ doesn't like.
You could also try using WIC to open the TIF, perhaps you would have better luck there.

How to add a text Component ( text annotation) to the Tiff Image

Hi.............
This is the first time I am using Sun Developers Forum.......................
My problem is.............I want to add a component ( Text or Label ) to the Tiff Image which is displayed on the JIMICanavs [ from JIMI API ].
Even , if anybody knows about How to add a component to the JIMICanavs , Please help me..................................

I'm curious: is JIMI still popular? What advantange does it have over the current Java 2D support in the J2SE, or over JAI?

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

How can I merge two TIFF images in one...?

I need some help please, I am looking for a way to "resize" black & white single TIFF images.
The process I need to do is like cutting a small image and paste it over a new blank letter-size image (at 300 dpi), like a template.
Or better yet, is there a way to do something like this...?
Open image...
image.*width* = 2550;
image.*height* = 3300;
image.save();Some APIs and topics in the internet do or talk about resizing, but the final images get stretched or shrinked and I need them not to do so at all.
Also, I do not need to display the images, only to get the TIFF images processed and saved back to a file.
How can I do this with Java and JAI? Unfortunately I am almost new to this and I don't know how difficult it might be to deal with images.

If 2550 x 3300 isn't the original aspect ratio of the image, then the image is going to looked streched or shrinked in at least one dimension. There is no way around that. It would be like resizing a 2 pixel by 2 pixel image into a 3 pixel by 6 pixel image. The image would look like it's height shrunk or it's width stretched. Had I resized it to 3 pixels by 3 pixels or 6 pixels by 6 pixels, though, then it wouldn't look shrunken or streched.
Open image...
image.*width* = 2550;
image.*height* = 3300;
image.save();*1)* To open a TIFF image you can use the javax.swing.ImageIO class. It has these static methods
read(File input)
read(ImageInputStream stream)
read(InputStream input)
read(URL input) You can use which ever method you want. But first you need to install [JAI-ImageIO|https://jai-imageio.dev.java.net/binary-builds.html]. The default ImageReaders that plug themselves into the ImageIO package are BMP, PNG, GIF, and JPEG. JAI-ImageIO will add TIFF, and a few other formats.
The downside is that if clients want to you use your program on their machine then they to will need to install JAI-ImageIO to read the tiffs. To get around this, you can go to your Java/jdk1.x.x_xx/jre/lib/ext/ folder and copy the jai_imageio.jar file (after you've installed JAI-ImageIO). You can also obtain this jar from any one of the zip files of the [daily builds|https://jai-imageio.dev.java.net/binary-builds.html#Daily_builds]. If you add this jar to your program's classpath and package it together with your program, then clients won't need to install JAI-ImageIO and you'll still be able to read TIFF's. The downside of simply adding the jar to the classpath is that you won't be able to take advantage of a natively accelerated JPEG reader that comes with installing JAI-ImageIO (instead, ImageIO will use the default one).
*2)* Once you've installed [JAI-ImageIO|https://jai-imageio.dev.java.net/binary-builds.html] and used ImageIO.read(...), you'll have a BufferedImage. To resize it you can do the following
BufferedImage newImage = new BufferedImage(2550,3300,BufferedImage.TYPE_BYTE_BINARY);
Graphics2D g = newImage.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(oldImage,0,0,2550,3300,null);
g.dispose();Here, I simply drew the old image (the one returned by ImageIO.read(...)) onto a new BufferedImage object of the appropriate size. Because you said they were black and white TIFF's, I used BufferedImage.TYPE_BYTE_BINARY, which is a black and white image. If you decide to use one the BufferedImage types that support color, then a 2550x3330 image would require at least 25 megabytes to hold into memory. On the other hand, a binary image of that size will only take up about one meg.
I specified on the graphics object that I wanted Bilinear Interpolation when scaling. The default is Nearest Neighbor interpolation, which while fast, dosen't look very good. Bilinear offers pretty good results scaling both up or down at fast speeds. Bicubic interpolation is the next step up. If you find the resized image to be subpar, then come back and post. There are a couple of other ways to resize an image.
Note, however, if 2550 x 3300 is not the same aspect ratio as the the TIFF image you loaded, then the resized image will look shrunk or stretched along one dimension. There is absolutely no way around this no matter what resizing technique you use. You'll need an image whose original dimensions are in a 2550/3300 = .772 ratio if you want the resized image to not look like it's streched (you can crop the opened image if you want).
*3)* Now we save the "newImage" with the same class we read images with: ImageIO . It has these static methods
write(RenderedImage im, String formatName, File output)
write(RenderedImage im, String formatName, ImageOutputStream output)
write(RenderedImage im, String formatName, OutputStream output)You'll suply the resized BufferedImage as the first parameter, "tiff" as the second parameter and an appropriate output for the third parameter. It's pretty much a one line statement to read or write an image. All in all, the whole thing is about 7 lines of code. Not bad of all.
Now as for the 300 dpi thing, there is a way to set the dpi in the Image's metadata. I'm pretty good at reading an image's metadata, but I've never really tried writing out my own metadata. I know you can set the dpi, and I have a somewhat vague idea how it might be done, but it's not something I've tried before. I think I'll look more into it.

How do I Convert a Tiff image to a jpeg without being FORCED to 8-bit Color?

I am an Artist. I have High quality TIFF images. When I convert the tiffs to jpeg it forces me into 8-bit color automatically. (Forget about 32bit - it will not allow me to jpeg that at all) The only way I can get back to 16bit color is to use the already SMAshed file and bring it up to 16bit. THIS makes NO sense. Once the jpeg is smashed, HOw in the world is it supposed to convert up again. ?? Then even though it says you converted the file to 16 -bit , the metadata refers still to the file as 8-bit.
On top of all of that confusion, One picture, for example, when supposedly converted to 16bit, gets much BRighter then even the original Tiff image. It looks good on one hand and over exposed on the other. I assume that is photoshop throwing in fake resolution, am I right?
Am I wasting my time with this imaginary 16bit conversion?
Is there ANY way to take that original Tiff image and convert it to 16bit jpeg without the Default 8bit? I have been trying all kinds of things. I even have asked my web guy. My web guy says that 8-bit is unexceptable for printing, even for web.
Could this have anything to do with my computer and scanner?
I have the iMAC OS X 10.8.3 (3.2 GHz) 8 GB memory.
And I also have an Epson Expression 10000XL graphic arts scanner capable of scanniing at 48bit color.
This color stuff Really matters! It MATTERS! I HAve FINE art files. I am already losing so much quality with the jpeg conversion. (which I am required to do for SmugMug, in addition to compressing all my files to 50mb or Under)
Anyone who knows anything that could help me would be much appreciated.
Aloha,
-Melissa

First of all jpeg is 8 bit only there is no way to save as a 16 or 32 bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are in 8 bit as that is the only way to view it as there is no 16 bit or 32 bit monitors to view it. All but a few pro monitors are 8 bit monitors.
If you care about the color gamut and want the full range of color that 16 and 32 bit provide, then why jpg? Jpg by its own nature throws out color just to compress, thats why it is popular on the web, because of its small file size not its quality. If you need 16 or 32 bit for anything it must be in a format that supports that color depth.
That being said a jpg image at 8 bit will display 16+ million colors, 256 shades of red, 256 shades of green and 256 shades of blue.
Now here is where I think your bit information is off. a jpg image is a 24 bit image that will produce 8 bits of red, 8 bits of green and 8 bits of blue.
The 8, 16 and 32 are per channel not total color information.
If the overall image was 8 bits, the image would be gayscale.

The images imported to my stage turn up as blank and render every image previous to the rogue imported image as red squares that fill the perimeters of the image which then renders the publishing and scene testing features in flash useless, what can i do

I have been working on animating a scene in flash for a few weeks and recently I have encountered a problem with importing my images on to the stage where the images I import do not turn up, however the key frame that I attempted to import the image onto shows that it is occupied by an image and every frame previous to the key frame that just imported an image that does not show turns up as a red square that fills the original perimeters of the image, there is no solution to this problem any where on the forum and the adobe technical support staff will not help me find a solution to this problem what can I do to get Flash running normally again and fix this problem?????
Also after the first time i publish a preview after i begin using flash, flash renders the publishing and scene testing features as useless and claims that there is no HTML template found, or if the images if i import any images onto the stage that come up blank and render every image previous to that image as a red square and then try and publish a preview flash renders the publishing and scene testing features as useless and claims that there is no HTML template found. What can I do to fix this problem??? there is no solution on the web anywhere to this problem either.

I don't know if Flash has a memory limit of its own. The memory for your Flash file is based on the available memory on your computer.
There is a limit on the number of frames that you can have in any given timeline. I think that it's about 15000 frames, but that's a guess. Flash does all of its work at runtime, this means that no part of your animation is pre-compiled like it is in a video file. So the more objects that you have on the stage, the more work Flash has to do. It follows that the more objects that there are to animate, the more work your processor and the video card have to do.
Here's a list of articles on memory management that might be useful:

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);
 }
