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,

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.

How can I convert a wave file to a jpeg file (picture) is it possible???

Hello:
How can I convert a wave file to a jpeg file (picture) is it possible???

zuckini;
I am pretty sure you know, but just to be completely sure: a wave is (usually) sound signal and a jpeg file is an image.
If you mean how to display the wave signal in a graph and then save the graph as a jpeg file, then just drop a graph indicator in the control panel, wire the signal. Check any of the example shipped with LabVIEW on how to do this. To get the image, drop a graph indicator's invoke node in the block and select "Get Image". Check this page for detailed information.
If you have something else in mind, please reply to this message with additional information about the wave signal, the image, etc.

How can I convert my Tiger DVD into a CD without spending more money?

How can I convert my Tiger DVD into a CD without spending more money and time? I've spent over seven hours trying to upgrade an iMac 350 Hz OS 9.1 to Tiger. I have changed the iMac firmware to 4.1.9, but found that my Panther disc was only an OSX Upgrade, although the 3 cds are labeled as Installation Discs. Since I have a Tiger disc I thought I would use that. Unfortunately, my iMac only reads CDs, not DVDs. I tried networking the iMac to my G5, but upon shutdown, the OSX disc cannot be accessed. I copied the DVD files to my iMac hard drive, but again, the OSX disc cannot be accessed after shutdown.
Is there a way I can burn a CD from the files of my Tiger DVD to get this task accomplished?

Excuse me, but I never thought of that, nor did I have any intention of trying to rip off your company.
I purchased four iPods for my family this Christmas. I have six iMacs just sitting around not being used. I thought that I would turn one into an iPod work station, so everyone can use one computer to recharge and hook up to iTunes 7.
Unfortunately, iTunes does not work very well in OS9. Apple decided not to continue to support OS9 very well. I’ve spent several hours attempting to upgrade the iMac so I could set up iTunes 7. Unfortunately, my 3 Panther Installation Discs were mislabeled, and did not allow me to install OSX over OS9. My OSX 10.2.7 Installation Disc is a DVD, and my Tiger Installation disc is a DVD. Neither usable to update the iMac.
All I want to do is set up a dumb iMac as a network interface to my G5 because I've use all of the G5's ports for our recording studio and the iPods need external power source if they are plugged directly into the G5.
If you could show me an easier way to run iTunes 7 on the iMac I wouldn't be as ****** off as I am at Apple for not supporting the 9 older computers I own with usable help and upgrades.

Once i realized to change the tick box in Camera Raw to 8 bit instead of 16 bit and Flatten image ( sometimes can flatten image if the flatten option isn't greyed out) hey presto i thought i was up and running. However after saving the photograph as a jpeg and renaming it e, after the word edit. I switched off/on my computer only for all the images i had spent time working on to have disappeared. Feeling very upset as there is no Technical Help to telephone at adobe and i don't know what to do.

My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

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.

Convert a Tiff Image to png and show

Hello;
I wanto to convert a Tif image to png and show this in my web page but i dont want to save the png iamge in my server.
Actualy i do that:
byte[] bytes = imagenData;
                ByteArraySeekableStream tiffStrm = new ByteArraySeekableStream(bytes);
                String[] CdcNms = ImageCodec.getDecoderNames(tiffStrm);
                ImageDecoder tifDecoder = ImageCodec.createImageDecoder(CdcNms[0], tiffStrm, new TIFFDecodeParam());
//                 Check the number of pages
                int IFDs = tifDecoder.getNumPages();
//                 Get the first page
                RenderedImage ren = tifDecoder.decodeAsRenderedImage(1);
                byte[] bytes2 = doSingleConversion(ren);AND
protected byte[] doSingleConversion(RenderedImage tifImage) throws Exception
          byte[] bytes = null;
          String out = "temp.png";
          try {
               //      Create the PNG file
               PNGEncodeParam pngParm = PNGEncodeParam.getDefaultEncodeParam(tifImage);
               JAI.create("filestore", tifImage, out, "PNG", pngParm);
               //Read the file into a byte array
               File f = new File(out);
               FileInputStream in = new FileInputStream(f);
               bytes = new byte[(int) f.length()];
               in.read(bytes);
               in.close();
               return bytes;
          catch(Exception e) {
               e.printStackTrace ();
               throw(e);
     }But this code save de image in the server; it�s posible do it without save.

I do not have NI-IMAQ or NI Vision.
I acquired the image using a picolo board then just saved it as a bitmap file.

You want to convert it to an array of what? Of numbers? Of LabVIEW colors?
The "Read BMP File.vi" VI outputs a 1-D array of the pixels, but I suspect it is not exactly in the format that you need. I am NOT sure, but I think that each group of 3 elements of that 1-D array (which is inside the cluster "image data" that the VI outputs) represents the red, green and blue levels of a single pixel (but it may be hue, saturation and lum.). Also, since it is a 1-D array, you would have to divide it by the width (which is also included in the "image data" cluster) to get some sort of 2-D array of data.
You can find the "Read BMP File.vi" VI in the functions palete> "Graphics & sound">"Graphics Formats".
