SAVING gif & jpeg files in differ graphic titles

SAVING gif & jpeg files in differ graphic titles appear
presave settings... what are ?
gif
===
Row Order: Normal or Interlaced
jpeg
====
Format Options: Baseline-Standard or Baseline-Optimized or
Progressive

else if(fileName.endsWith(".jpg") || fileName.endsWith(".jpeg") || fileName.endsWith(".gif")) {
    response.setContentType("text/html");
}You're forcing images to use contenttype text/html instead of binary image.
This is a weak control though. Rather use URLConnection#guessContentTypeFromName() to retrieve the contenttype.
Also see the following articles for ImageServlet and FileServlet examples to get some new insights:

  • Saving a JPEG file for printing

    When saving a JPEG file for printing using Elements9, should one use "baseline standard, optimized or progressive"?

    Thanks, Andromeda....  I see that PSE8 Organizer has the ability to update the Caption as you have described.  The caption appears in the Description field in the General area and in the Description field in the IPTC area of the image file.  I was unable to update the Title or any other fields using Organizer.  Looks like PSE8 Editor must be used to update all the metadata fields in the image file.  Thus far, the only way I have been able to update the metadata in a JPEG file without having to re-compress it is with a HEX editor.  This, however, is a slow process at best.  Too bad Organizer or Editor does not provide the abilty to update all fields in the metadata without having to recompress the file.  I am not a programmer; however, it would appear to be a fairly straight-forward process.  Thanks, again.

  • Edited RAW files not saved as .JPEG files

    Before I updated to iPhoto8, when I edited my RAW files they were saved to JPEG files automatically. From the Help documentation, I believe that this should still be happening..... but it isn't.
    Do I have a setting wrong? Anyone know?
    Thanks.

    Check the entry "About nondestructive editing" in iPhoto Help. With iPhoto '08 you will not see the "save" progress bar unless the photo was previously edited in iPhoto 6. Here is a portion of the text:
    Nondestructive editing allows you to try different adjustments and effects at will⎯there’s no danger that successive edits and saves will degrade your photo’s quality. You’re never more than one version away from your original photo. Instead of saving a new version over the previous one every time you edit a photo, iPhoto ’08 simply remembers all your changes as an edit list.
    When you reopen your edited photo to view or do more work, iPhoto then reapplies those edits to the original version. You’ll see where you left off, so you can make incremental changes from there.
    IMPORTANT: For photos imported to earlier versions of iPhoto and never edited, nondestructive editing will apply in iPhoto ’08.
    However, for photos imported to earlier versions and edited either in iPhoto or in a separate application such as Photoshop, nondestructive editing does not apply.

  • How to convert images to gif/jpeg files

    I have created images in java. Now i want to convert this image into a gif/jpeg file so that i can save this gif/jpeg file in one particular folder on the system & also show the same file to the user.

    use
    javax.imageio.ImageIO.write
    for an introduction see:

  • Can doc files be saved as jpeg?

    Can doc files be saved as jpeg files on Macbook Pro?

    The problem with screen capture is that it only captures the section of the document currently visible on the screen, which is awkward.
    The better option is Print > Save as PDF, then open with Preview and convert to JPEG.
    The problem is that both .doc and .pdf are, or can be, multipage, while .jpg is a single image. Consequently, Preview will only convert to JPEG the current page, hence pages have to be converted one by one; which is fine, if the .doc consists of 1 or 2 pages; otherwise, you'd have to find another converter (eg, GraphicConverter) or script it. Perhaps the real solution is to examine why would you want to convert .doc to .jpg in the first place. PDF is well-nigh universal, and should be readable on any system, even quite old ones.

  • Java Swing - save JPanel as GIF/JPEG.

    WE are using Java swing to draw graph(Genes, SNP ,repeats etc related to bio-informatics).text files we are using are quite big eg- more than 25 MB. first it makes the process slow.One of our problem is to save whatever "we draw as an image file(GIF/JPEG file)" and another problem is save a data in a data structure(array,vector) which grow upto 15-20 MB.
    plotting this data makes the speed too slow.We want to optimize this.

    For saving images have a look at JAI - the Java Advanced Imaging API. It's got fairly straightforward ways of saving images. Note that saving as GIF images is not recommended; patents were placed on the encoding so it's no longer a free option. PNG will give you lossless compression like GIF but is more flexible.
    http://java.sun.com/products/java-media/jai/
    Saving the generated (mined?) data structure for future retrieval can be quite straightforward depending on how you're doing it. The easiest way is simply to serialise it (use an ObjectOutputStream) but this has compatibility problems if you change your data structure.
    Saving out in a custom format may seem like a lot of work but it's not all that hard to do. Alternatively you can use one of the Java to XML convertors - in your case this might generate too large a file, however.
    YOu can always use Java's zip functions to improve file size should this become problematic.
    Hope this helps

  • Gif@jpeg as map

    Hi,
    I would like to know how to insert gif@jpeg file to become Image object and after that as a Graphics object. Actually, I want to make that gif@jpeg file as a background(map) and I can click to that map to extract the coordinate for the specific city.
    below i list my "not working" coding
    Image img = Toolkit.getDefaultToolkit().createImage("kedah.gif");
    Graphics g = img.getGraphics();
    I found that method createImage() from Component class is working to create Image object but with parameter as below..
    public Image createImage(int width, int height)
    Anybody can help to solve my problem?

    This would depend on the release date. We have an application that our major client has used for a number of years which uses the SVG base maps only. We would like to migrate it to use oracle maps, we would need a time scale to present to our client so that they can decide how much to invest. The application is due for a revamp, given that Adobe no longer support the plugin it would make sense to move away from it, especially for cross browser and next gen windows support.

  • Importing JPEG files from powerpoint - Please help I'm on a deadline!

    I've been importing slides from powerpoint (saved as JPEG files) into imovie (there are 7 in all). I've done this without a problem. I decided I wanted to change some of the words so I went into my original powerpoint file, did my changes, and saved the slides as JPEG files as usual. For some reason now when I import each of the slides they're huge so the words are cut off. I've been trying to reduce the font size but now it's getting hard to read! Does anyone have any ideas as to why I'm suddenly having problems and how I can fix this? I need to ship this out today by 5pm EST.
    Thanks!

    Thank you for your help!
    Would you know why it's now importing these files in such a way that I"m not able to change the length of the slide? (it's importing it for 2 seconds almost as if it's a movie file - it has a little play button on the top which looks different from my other files)

  • How can i convert .gif/.bmp/.jpeg file to labview code(vi)?

    Hi,
    I am having a .gif file which consists of vi code. I want to convert that .gif file into vi & complile it. I am using LV 6.1 & 7 express. Is is possible?
    Reverse is surely possible like we can convert the vi diagram into .gif/.bmp file? But above i dont know?
    Your help will really appreciated.
    Best Regards,
    Nirmal

    If I understand your desire, it's to be able to convert a graphical image (bit map or screen photo, for example) into a functional block of LabView code, with all of the wire work done, etc. This is a task approximately equivalent to performing optical character recognition.
    In the case of a non-system subvi, unless that subvi is loaded, so that it's graphical representation can be recognized by comparing the bit-map image for the subvi on the photo with the available vi's.
    Another difficult problem to solve is when the bit-map has been scaled up or down, such that there's a pixel count mismatch between the VI iconic bitmap and the photographic bitmap you wish to import into your code diagram.
    And if you try to do recognition on objects that have h
    ad their RGB color representations changed, as can happen when JPG compression or other compression forms are used that reduce to total number of colors saved, that challenges the object recognition further.
    Also, what you're interested in having is only of value to Labview programmers, so there's not a very large market for such a tool to be sold to - unlike bitmaps of scanned text to ASCII or wordprocessor applications - traditional OCR software.
    All this ins't to say it can't be done, but that it's difficult, and for the person or company that undertakes it, the sales potential is limited.

  • File Info not saved (.gif) (Ps CS6 Extended, Mac)

    I'm not certain that I've been building my workflow properly before, so if this was not supposed to be supported, I'm open to that possibility:
    Modifying the "file info" for a gif file (in my case, "General" tab, "Document Title" and "Description") doesn't actually get saved with the file - or, at least, if it is saved, it's not visible when re-opening the file.
    I believe that I understood that metadata for .png format isn't supported, but I thought that .gif was. 
    (Test case is easy: open .gif file, add a Title and Description, save, and re-open - information is gone).
    Thanks for any help anyone has...

    hi Chris & thank you for your response
    it doesn't seem possible to add File > Info to a .png image in Photoshop itself. i've tried it a few different ways.
    (shoot, actually i should try adding it again in Ps to a .png file and then see if Bridge can read it. hmmmm??)
    in an other thread: [ http://forums.adobe.com/message/5642141#5642141 ] Gene told me that i could select Copyright and Contact Info from the Metadata drop down menu in the Save for Web panel to add the info to a .png image but this didn't work.
    i don't know if Ps is having one of its "fits" or what but nothing seems to be working.
    after a bit Gene was able to tell me that i can add File Info to .png files in the Bridge Cs6 or CC (no idea what the difference is between Ps Cs6 and Ps CC) and so i tried that and it worked.
    however, it appears that Ps still cannot read the data/info when the .png image is opened in Ps itself. Only readable in Bridge.
    which brings me to an other Q ... what's the point of Copyright info that can't be read? i am not being sarcastic i just really don't understand. granted, i need to read up on this topic but was hoping you could share your thoughts/knowledge w/me   oh, and if you have any handy links i would also much appreciate it. thanx 4 ur help!!

  • Creating GIF or JPEG files

    Is it possible to render a graphic object into a GIF or JPEG file and save it in a Java application?
    Thanks.

    For JPEG:
    1) Try JAI (http://java.sun.com/products/java-media/jai/) or the Java Image I/O from JDK 1.4.
    2) Try PJA (www.eteks.com)
    There is a pitfall if you want to do imaging in a Unix/Linux machine and the Java program can not access a X Server (maybe the machine is not running X). In this case you must install a "fake X Server", or use PJA.
    For GIF:
    Due to LZW patent problems with GIF compression the packages that generate GIF files have(had) to get a Unisys license.

    I am batch processing in PS 2014 (watermark and saving as jpeg from ps file). I get the message for some but not all 'this file needs to be saved as a copy with this option'. And then I have to save it manually. Does anyone know why this happens? (It is just a plain photoshop file, a watermark is added, then save as jpeg - the jpeg is saved to a different folder than the original photoshop file.)  It happens for about 10 of 30/40  files approximately . Thank you, Kathryn

    I believe I have figured it out - I need to flatten the image, even though there are no layers except for layer 0, first.

  • Newbie question: saving jpeg files in indesign document

    hi there,
    i'm rather new to indesign and i can't get this thing to work:
    whenever i place a jpeg image (or for that matter, any other image format) into an indesign document and later move
    the jpeg file to a different location on my harddrive and then reopen the indesign file, the image is all pixeled. it seems like the image
    isn't saved inside the .indesign file, but is more of a referal to the file on my hard disk.
    is it possible to embed external files (like jpeg) into the actual indesign document and save them within this document?
    i'd be gracious for any help.

    Grant's answers are correct. You SHOULD use linked images and you should update them on the Links panel.
    There are specialized reasons it might be necessary to embed an image, but in general it's not a good idea: (1) It makes the files unnecessarily large, (2) if you make changes in the image, it can be updated in the InDesign file.

  • My .cr2 files turn a tinted blue after saving as jpegs in ACR CS5

    After color correcting a batch of about 100 images, I saved as jpegs and then hit done and a select few of the photos turn a tinted blue. All of the other settings stayed the same.. Does anyone have a clue as to what is going on? Or need me to explain more?

    It sounds like user-error where an image off screen is still accidentally selected when tint is being adjusted on another group of images, perhaps with a mixture of fluorescent and daylight images, which have a significant difference in tint so the adjustment of one would be obvious on the other.
    Since you posted here, I’d guess you don’t feel it is user-error and the ACR plug-in is doing something to cause the issue.  Because it is across two different versions of Photoshop and occurring with different people, a bug would have to be longstanding, but I don’t recall others reporting it.  Sometimes there are sliders that stick or become activated when an unrelated context is exited from (maybe I’m remembering things in Lightroom not ACR, though) so when the mouse-wheel is moved a slider unexpectedly moves instead of the thumbnail list scrolling, but that sort of thing should be obvious on-screen and not only when the JPGs are written.
    Does the WB adjustment ever happen near the end of the process so it is the last thing done and a last-minute error might go unnoticed if ACR had not had a chance to redo all the thumbnails?
    Is this a relatively new crew of people or a very light or very heavy load, where lack-of-attention or pressure could be leading to selection errors when and adjustment is applied and extra photos are getting selected by accident?  Is there anything different about the one person who hasn’t seen the problem?
    Is there anything with the computer monitors that make it difficult to see what images are selected?
    It might be interesting to look at the timestamp of the XMP files (if you use those) to see if the one with a bad WB was updated at a different time compared to the ones surrounding it that all were probably done at the same time. 
    Are these files all local to each computer or are they being shared from a central location?
    With a bug it would be nice to have a documented procedure that will always lead to the problem.  Something intermittent that cannot be reproduced by Adobe isn’t going to get fixed. 
    If it happens relatively often, then you could record an entire session using a screen recorder (like camtasia or similar), or using a video camera over someone’s shoulder, and then play it back and look for either user-error, or as proof that there was none, but strange things happened.
