Height and Width of an image - URGENT!!!!

how I make to catch the height and the width of an image being used one upload JSP?
Since already I am thankful!

Toss the image up in the air. Turn both of your hands so the palms face skyward and towards the image while keeping them next to each other. As the image descends into your palms, close both hands tightly around the image.
No, seriously, what do you mean by catch the width and height of an image? I'm assuming you mean how does one determine the width and hieght, right? You can probably stream out of the posted request into a byte array which you could pass to a javax.swing.ImageIcon object. You could then call getIconWidth() and getIconHeight() to get what you want. This approach would work for GIFs and JPEGs.

  • Trying to determine the height and width of an image.

    Hi Everyone,
    I am currently trying to work out the height and width of a number of pictures. I have tried a couple of techniques. One involved using BufferedImages, which kept on throwing null pointer exceptions. So I am now tring to use the Image class from java.awt.Image. However I need to use an ImageObserver or some such thing, of which I have absolutely no knowledge. If there is anybody out there who knows how to gather the information I speak of from a number of photos, and is feeling kind enough to impart their knowledge to me it will be greatly appreciated. Thanks.

    Well, maybe your problem is loading in the images, but I'm assuming you know what your question is since I don't feel like going into what ImageObserver does (That's what google is for).
    Anyways, to get the height and width of an image you do this:
    You initialize your image:
    Image image = getImage("file.jpg")  //I don't remember the if this is correct, it's just my memory.To get the dimensions"
    image.getHeight();If these return 0 it's more than likely because the image hasn't loaded correctly, which is why you need ImageObserver (IIRC there is a better API in the new ImageIO library, check the API).
    Best of luck.

  • How to resize and maintain height and width ratio IR image column

    Hello, I am upgrading from 3.2 to 4.1 reports that include images in report columns. I have had good success with this except for one thing. If the height and width is fixed it distorts the photos, and if I do not have fixed dimensions the image may be too large depending on the original dimensions of the :P1_PHOTO item which is File Browse... BLOB column. I do not want to restrict users ability to upload large image files, or files with different dimensions, but I want them to display as a thumbnail size proportional to the original dimensions in the report, or maybe I need a different approach? Report region template is No Template. I appreciate any suggestions.
    select decode(nvl(dbms_lob.getlength(photo),0),0,null,'<img src="'||apex_util.get_blob_file_src('P1_PHOTO',id)||'" height="75" width="75"/>') photo from table.
    I tried using percent i.e.: width="10%" that does not work.
    I have tried several variations of <style> in page HTML header to change column width, but the image size does not change.
    td[headers="PHOTO"] {
    #apexir_PHOTO{width: 75px;}

    Try to go with max-width / max-height. However, if you have IE browser, hang on for pain. For some ideas, some links:
    http://wordpress.mfields.org/2011/scaling-images-in-ie8-with-css-max-width/ (ignore object-fit, it is not yet supported on most browser)
    etc. Be sure to try out your chosen solution on the target browser(s)!
    IE is just nasty :(
    What i have done before is not to have my browser scale my images, especially when the images can be large(r) and you expect quite some traffic. All those extra (kilo)bytes won't help it load faster. I just added an extra column in the table, like photo_thumb, and create a scaled version of the uploaded picture when it is being inserted.
    For example, i have the following process on my apex page, and i'm using wwv_flow_files.
    Have some code:
         v_id number;
         v_small_photo blob;
         v_large_photo blob;
         v_mime_type apxt_contacts_img.mime_type%type;
         v_content_type apxt_contacts_img.content_type%type;
          SELECT blob_content a, blob_content b, mime_type, content_type
          INTO v_small_photo, v_large_photo, v_mime_type, v_content_type
          FROM wwv_flow_files
          WHERE name = :P3_FIND_PHOTO;
          IF lower(v_mime_type) NOT IN ('image/jpg', 'image/jpeg') THEN
             raise_application_error(-20001, 'File for upload is not a jpg!');
          END IF;
          -- Rezise the photo so that it is proportionally 125*125
          -- ordimage is an oracle type able to manipulate all sorts of pictures
          ordimage.process(v_small_photo, 'maxScale=125 125');
          -- If contact is of type personnel, then no need to store
          -- a large photo since it wont be displayed
          IF :P3_CONTACT_TYPE_ID = 2 THEN
            v_large_photo := NULL;
          END IF;
          -- Delete previously uploaded picture
          IF :P3_ID IS NOT NULL THEN
             DELETE FROM apxt_contacts_img
              WHERE contact_id = :P3_ID;
          END IF;
          -- Insert the data into the contacts_img table as a
          -- SELECT from WWV_FLOW_FILES
          INSERT INTO apxt_contacts_img
          -- Remove the image from the apex wwv_flows_files table
          DELETE FROM wwv_flow_files WHERE name = :P3_FIND_PHOTO;
    END IF;

  • How do I view the height and width of an image as I adjust the crop handles

    How do I view the height and width in pixels of an image as I adjust the crop handles before I actually crop the image?

    If you are in Photoshop CC, go into Preferences, click Interface, and turn on Show Transformation Values. In the picture below, setting it to Top Right means the pixel height and width appear to the Top Right of the Crop tool pointer.
    (Edit: The picture only shows Height because the bottom edge is being dragged. If a corner was being dragged it would say H and V.)

  • Height and width of image loaded into blob?

    i am loading images into my database which is all working fine. in parts of my app i am displaying these images so i am wondering is there a way to get the dimensions (height an width) of the image you are loading in so that when it comes time to display you can scale as needed but the aspect ratio is the same so then the image is not distorted by just putting some random values for height and width.
    instead of
    select decode(file_type,'I','<imge src="OWNER.download_file?p_file=' || nvl(file_id,0) ||'" height="100" width="100" />','') from project_file
    where file_id = :P31_FILE_ID
    i want to replace 100 with values from columns in table that were loaded at time of save
    Message was edited by:

    thanks scott. is it correct to say that this example is storing the image at whatever size the user puts in the width and height boxes on screen? thats what it looks like to me anyway. i see there are functions to get these but does the user have to enter them still? it will be just what i need if indeed I do need it!
    Yes, that's correct. Of course you could modify the code so that you choose the size of the image, and not allow the user to change it.

  • Animated Height and Width

    I'm trying to write lingo, that tells a certian object, upon
    the mouse leaving, to scale down by x amount. However I want it to
    be animated and happen over time. But I want it to all be in Lingo,
    within the cast member. I have it looking like this right now, but
    this just makes it go from one size, immediately to a smaller size.
    Like I said, I would like this to happen over a period of say, .5
    on mouseLeave me
    sprite(2).height = 438
    sprite(2).width = 292
    I'm doing this for something like a portfolio. You can roll
    over images and they get larger, but when you roll off of them,
    they get smaller. I just want them to get smaller over time, and
    not immediately. Any help would be great. Thanks.

    Since mouseLeave only happens once it can't easily be used to
    something... so, you need to set up a system where the
    shrinking happens
    on an event that happens more often (like enterFrame)
    property pShrink
    on beginSprite me
    pShrink=0 --set it to not shrink when it starts up
    on mouseLeave me
    pShrink=1 --start shrinking now
    on enterFrame me
    if pShrink=1 then
    if sprite(2).height>400 then
    pShrink=0 --now it will stop shrinking
    end if
    end if
    This script kind of assumes that the sprite is square, since
    it adjusts
    the height and width evenly. Change those lines where the
    width and
    height are lowered by 2 to a greater number to make it go
    faster or a
    lower number to make it go slower (it has to be an integer,
    so 1 is as
    slow as it gets). Also, if the height and width are not
    equal, then
    adjust those same numbers accordingly. I also chose the
    number 400
    fairly arbitrarily.. that should be whatever height the
    sprite should be
    when you want it to stop shrinking.

  • Height and width question in an applet

    I have loaded a picture into an applet. Is it possible to get the pictures height and width?

    I assume you loaded it into an image. In this case, you can call Image.getHeight() and Image.getWidth(). If you get -1 returned, search for a useful thread on ImageObserver.

  • Can PDF's be resized? (height and width)

    I have a large PDF booklet that I would like the height and width reduced.  Is this possible?

    If Dov see's this, I'll get reprimanded, but...I do not see him here often.
    Downscaling will not have the caveat of upscaling, where there would be an effective loss of image/pixel resolution.
    Obviously for a one time print, you could use the page scaling from the print dialog. If you need a more permanent solution, you could set up a custom page size and print to pdf, effectively re-frying the pdf. The result would include a loss of color management, multimedia content, bookmarks(?), live transparency and other behind the scenes elements within a pdf. To much extent, it would appear and behave as a typical pdf, but advanced features are stripped out when handling a document this way. (Sometimes, for the better, IMO)
    Optionally, preferably, and untested, I would place the pdf into InDesign, scale accordingly and Export to pdf. Given the proper export settings, I believe more original structure would be maintained.

  • Can I turn off the setting that displays the height and width in a little black box when using the marquee tool?

    In Photoshop CC, on a mac...
    When using the marquee selection tool, a little black box pops up next to the curser and displays in real time, the height and width of the selection.  The same annoying box also appears when dragging an item with the move tool, displaying the numerical location of the cursor.  Is there anyway to turn off the display of that little black box?  It is driving me bonkers.

     In the property nodes, i am just able to read the bound values but cudnt write to it.
    How can i set the bound values for a control?

    Not all controls can be sized this way. For example to change the vertical size of a simple numeric, you would need to change the font size.

  • Dynamically size movieclip to fit text's string height and width

    I am trying to dynamically size a movieclip to fit the size of a text's string height and width (This text is inside the movieclip)
    here is my code so far..
    var Font1_ = new Font1();
    var Format2:TextFormat = new TextFormat();
    Format2.size = 36;
    Format2.align = TextFormatAlign.CENTER;
    Format2.font = Font1_.fontName;
    var MessageBox:MovieClip = new MessageBoxMC();
    MessageBox.Text1.defaultTextFormat = Format2;
    MessageBox.Text1.embedFonts = true;
    MessageBox.Text1.antiAliasType = AntiAliasType.ADVANCED;
    MessageBox.Text1.wordWrap = true;
    MessageBox.Text1.width = 800;
    MessageBox.Text1.height = 400;
    MessageBox.Text1.textColor = 0xFFFFFF;
    MessageBox.Text1.cacheAsBitmap = true;

    this isn't working for me.. anyone know the best way to do this?
    I also want the text to be centered in the movieclip, with a border of around 2-4 pixels
    I am also not sure if i should be using text.length? any advice and input is greatly welcomed.
    thanks in advance!

    Essentially, you need to check for a change in .textWidth or .textHeight, which are different from .width and .height.
    This code works for me (assumes a background box called bg and a foreground text instance fg inside a moveclip and an X and Y bounds offset variable to say how far away you want the box from the text and a textFrameNudge to provide a tweak value).
         // Resize background box
         thisBox.bg.x = thisBox.fg.x - boundsOffsetX + textFrameNudge; // I'm using .4 as the tweak value for textFrameNudge
         thisBox.bg.y = thisBox.fg.y - boundsOffsetY;
         thisBox.bg.width = thisBox.fg.textWidth + boundsOffsetX*2 +textFrameNudge*thisBox.fg.getTextFormat().size;
         thisBox.bg.height = thisBox.fg.textHeight + boundsOffsetY*2;
