How can BufferedImage convert to  Image?

I want to use a BufferedImage to create a new ImageIcon, as ImageIcon(Image img), How to convert it to image without creating a new Image.
Thanks.

In other works, a BuffedImage is an Image.
Kinda like a Ford is a Car. Of course, not necessarily that any Car is a Ford, neither is any Image necessarily a BufferedImage. But a BufferedImage is always an Image.

  • How can you convert an image to ydbr format?

    Hello all. I can not work out how to simply input an image and convert it to ycbr and save it as a new image.
    Can anyone help please?
    Kind Regards

    OK I have also found this code:
    public static void rgb2ycbcr(int r, int g, int b, int[] ycbcr) {
              int y = (int)( 0.299 * r + 0.587 * g + 0.114 * b);
              int cb = (int)(-0.16874 * r - 0.33126 * g + 0.50000 * b);
              int cr = (int)( 0.50000 * r - 0.41869 * g - 0.08131 * b);
              ycbcr[0] = y;
              ycbcr[1] = cb;
              ycbcr[2] = cr;
    However I have no idea of how to use it. The source did not specify what all the parameters are. How can I use this in my code from a bufferedimage to displaying the new image?
    Thanks again.
    Looking forward to your answers (3 more Dukes added)

  • How can I convert an image created in Photoshop into a format that Java's ImageIO library will take?

    Hi all,
    I've been trying to write an image resize tool to use the Lancoz resample algorithm to resize images to a high standard in Java.  The library with the algorithm/filter in it is mortennobel's image scaling library and it takes a buffered image as an input and returns the resized image as desired.  However the trouble I’m having is that the ImageIO library in Java, a standard library, which converts images given to its read method to buffered images doesn't accept certain images created in Photoshop and so it throws an exception.  My library needs to be fully automated to process possible thousands of images at a time and so manually converting them by resaving them as JPEG's is really feasibly.  Is there some way I can convert these images from Adobes Exif format to standard JFIF format?  I've tried simple inserting the APP0 marker from a JFIF image in-between the SOI and APP1 marker but the ImageIO library still failed.
    The above image is a screenshot of the binary in hex of one of the images that cause an Invalid Format exception when passed to ImageIO.
    Any help you could offer me with this would be much appreciated.
    Kind regards and thank you,

    NB: I previously posted this post in Developers but was told to post it in a Photoshop forum so apologies if this is the incorrect formum

    The image scaling library does have a BiCubicFilter in it so I'll experiment around with them and see what happens.  As for the imageIO library I think it accepts Exif image types, but still for some reason it just doesn't like Adobe Photoshop types.  Maybe its the colour map it doesn't like I just can't seem to work out what's wrong which is slightly frustrating but looking round to see if I can find an answer

  • How can I convert an image into a color swatch set

    I have some experience with Photoshop and some with Elements 11 but I'm still getting used to it. Gimp, which is what I'm used to can do it so I'm sure Element should be able to. I have some really pretty Irises I'd like to onvert to a swatch.

  • How can I attach an image without the image is in the email body? (using the new mail the Lion)

    How can I attach an image without the image is in the email body? (using the new mail the Lion)
    I want in attachment, not in the body mail.

    I think your only solution is to zip the image files first and then attach them.
    Read this from a site I found:
    Sending Graphical Attachments -- When you attach a graphical image to your message, the recipient of your message sees the image inline (that is, in the body of the message) if her email client supports inline display. ("Take Control of Email with Apple Mail" contains a table listing the capabilities of popular Mac and PC email clients.) If a client does not support inline display (or the recipient has turned off the inline display option), the file appears as an attachment that must be opened in a separate program.
    On the one hand, an inline image is easier for the recipient to see - all she has to do is look at it. On the other hand, inline images can be frustrating to scroll through. If you do not wish to send a graphical image inline, you must compress the file before attaching it - Mail, sadly, lacks a built-in compression option, though fortunately for Panther users, the Finder offers Zip compression without requiring a separate application.
    Note that when you compose a new message, Mail always shows attachments in the body of your message. You can manually drag them somewhere else, but many email clients display all attachments in a separate list, regardless of where you place them in the message body.
    If you paste an image into a message or drag & drop an image from another window (say, a Web browser), Mail converts the raw image data to an attachment in TIFF format. On the other hand, if you drag & drop the icon of an image file (or use the Attach button to locate the file using the file browser), Mail leaves the attached image in its original format. This difference is significant, because although most email clients can display JPEG images just fine, support for TIFF - especially in non-Mac email clients - is less common. If possible, I suggest attaching image files as opposed to pasting or dragging in raw image data.

  • How can I convert a large batch of NEFs to JPGs in one step or action?

    How can I convert a large batch of NEFs to JPGs in one step or action?  I'm very new to Lightroom and know almost nothing about it, so I need to know step-by-step.  I've seen online advise about exporting but I don't know what that means - export from where to where?  Can anyone help me?  Thanks!

    I suggest you take a little time to watch some tutorials. If you are that new to Lightroom that you don't understand what export means then it would probably be a good idea for you to get some other information as well. If you don't I think you'll find Lightroom can be very confusing. You haven't indicated what version of Lightroom you are using. The link I'm providing you is a series of getting started videos for Lightroom 5. And just about everything in this series will apply to other versions. You will note that there is one video devoted exclusively to exporting images. But I think you really need to watch the whole series.

  • How can I convert iWeb page to html with NO javascript for email campaign?

    I have a holiday greeting I made in iWeb '09 for my business. The service I'm using to use to manage my mailing list wants me to strip all javascript code from the page so it is not seen as spam when it is emailed.
    How can I convert the page made in iWeb to an html page with no javascript?
    Thanks

    How can I convert the page made in iWeb to an html page with no javascript?
    You cannot. There will be nothing left. iWeb pages rely a lot on JavaScript.
    Use a template from Mail.app. Or create such template. These are simple TABLES and have no JavaScript in it.
    Do Cmd-Shift-G in the finder and type :
    /Library/Application Support/Apple/Mail/Stationery/Apple/Contents/Resources/
    Open one of the folders and open each successive folder until you see files like Picnic.mailstationery.
    Right-click to show the package content.
    Then navigate thru Contents, Resources until you see the files and images you need.
    Edit them to your hearts content.
    Double-click the file Picnic.mailstationery and it will open in Mail.app for further processing.

  • How can I convert (or switch) the RGB percent values from the LR histogram into RGB values which are shown e. g. in PS/CameraRAW?

    In LR 5.5 (same in previous versions) the RGB values in the histogram are shown in percent (relativ) values. I prefere to see the absolute values, but I can`t find any way to switch. Maybe this option is intentional disabled, because LR works in 16-Bit mode this would result in values up to 2^16. But as i compared the relativ values from LR with the absolute values from PS i run into a conversion problem. The following example shows the differences:
    CameraRAW : RGB, 128,0,0
    Lightroom: RGB, 43,8%, 19,0%, 6,2%
    CameraRAW: RGB, 0,128,0
    Lightroom: RGB, 29,8%, 47,5%, 17,5%
    Mainly i have two questions:
    1. Is there any possibility to change the percent RGB values in LR to absolut values?
    2. How can i convert CameraRAW values to LR values (see above)?

    TThe reason that a design decision was made from the beginning of LR to show only the percentage values was that RGB values are dependent on the color space and the LR histogram and numerical readout are derived from the Develop module's display space which is a hybrid color space with ProPhoto RGB primaries and the sRGB TRC. Thus the numerical values in the display would be different from the exported RGB image (in an orthodox space) and it was feared that this would be misleading. When soft proofing was introduced, because it involved converting the display to an orthodox space, it became possible to use the 0-255 scale in that mode.
