Question about transparent background

Hi,
I have created a simple graphic with 4 layers on a
transparent background. When I save this image as a jpg, gif or
flattened png, the transparent background turnsto white. What
should I do to save it as jpg or gif with a transparent background?
Thanks in advance

I set the Export settings and then exported as both Gif and

background looks transparent. I was happy.
Then I inserted the image in the blank HTML page. When I view
the page in Firefox, I can see the background color through the
image since the image background is transparent. When I view the
same page In Internet Expolrer, I see a bluish gray background
instead of being transparent. I don't understand where am I getting
this bluish gray color from.
Any clue?
Oh...sorry, yes. First, try index transparency, not alpha
transparency. For IE prior to version 7, you need to add some
JavaScript. For example, this script by
Drew
McLellan. Here's a
Google
search for more reading
Also, copying myself from
this
thread
quote:
JPG: This format has all 16.7 million colors, but it
compresses by throwing away "high-frequency" information (sharp
edges will blur funny). This format is good for photographs and
other images where colors change slightly from one pixel to another
(as in gradients). This format does not have transparency.
GIF: This format retains color information, but can only
support 256 colors -
any 256, though. It supports transparency, you can set one
of your 256 colors to be transparent. This format is good for
graphics with areas of solid colors. This format can also support
multiple frames in the same file, giving rise to animation.
PNG: This format retains color information like .gif and has
16.7 million colors, like .jpg. It handles transparency, too.
What's not to love? Well, not all browsers show .png files
properly. The major ones will, though, so if you know your audience
is mostly on one of the major or newer browsers (intranet use?
check your log files?), then you should be okay.
Index and alpha transparency. Index transparency means, more
or less, "make every pixel that is
THIS color fully transparent and every other pixel fully
opaque. Alpha transparency (often done with a mask of some kind)
means you can set the transparency of a pixel in the range from
fully opaque to fully transparent, from 0-255. These images are 32
bit: 8 bits for Red, 8 bits for Green, 8 bits for Blue, and 8 bits
for alpha transparency.
For the Web, you probably want to use index transparency,
because support for alpha transparency on .png files can be a bit
flakey. Support for index transparency is pretty good with the
newer browsers, but if a good portion of your audience is using
older browsers, you have some design trade-offs to make.
Probably good to read up on things:
Google
search for png support in browsers.

  • Question about alpha backgrounds

    Hello, I am just learning Motion and a bit confused. I am trying to drag in a picture that has a transparent alpha section. When I drag it onto the canvas the alpha background is black as expected, but when I drag the photo onto the timeline (which is what I want to do at the moment), the alpha background is white which I do not want. Why is there a difference, and if possible how do I get it to be black like when I drag it onto the canvas?
    I did a quick search through the manual and did not come up with anything. I also did a quick search through the forums and saw lots of stuff about setting the background to 0 or 100% in the project settings. That solution did not work for me. I also tried toggling on and off the alpha channel, but that just makes my image disapear, not the white background.
    I am more curious about why there is a difference in the two import methods, and if there is a way to avoid that.
    Thanks

    Check the alpha interpretation, sometimes Motion gets it wrong. Select the object in the Media tab of the Project Pane (not the Layers tab) and then go to the Media tab of the inspector, and try the different alpha interpretation options.

    This problem is related to GLOBAL NAMES.
    The simplest way to disable global naming is to alter
    the current session.
    alter session set global_names=false;
    The other solution is to add a global_name to the
    gateway/hs:
    HS_DB_NAME = <datasource>
    HS_DB_DOMAIN = <DOMAIN>
    But the HS_DB_NAME must not exceed 8 characters and
    must not contain any extra characters. If this is not
    possible, the globale naming can be disabled by setting
    GLOBAL_NAMES = FALSE in the init.ora of the database
    as well

    NO ERROR with TNSPING:
    This might be caused by an invalid SID configuration.
    Please make sure, that the SID in the listener refelects the
    SID specified in the TNSNAMES.ORA. Make sure you don't mix
    SID syntax with SERVICE_NAME syntax.
    If everything is configured well, please make sure that
    lsnrctl status shows at least one service handler for
    hsodbc. Probably restart the listener AFTER changing
    the listener.ora file.
    Still no error found, then please enable listener tracing
    (level support) and have a look at the listener.trace file
    after retrying the same select statement again.
    In the file you should see the connect from the Oracle
    database to the listener. After a few lines you should see that
    the listener tries to open 2 pipes. Does this work or does it
    fail and again a few lines later you see a hex/ascii block that
    conatins an error stack like:
    ERR=12500, CODE=12500, EMFI=4, CODE=12560, EMFI=4?
    Then please check again the listener.ora file; is the
    ORACLE_HOME directory specified within the listener.ora file
    correct? Or if you are using environment variables in the
    listener.ora please replace them with absolute paths.

    This behaviour can be found in situations with a version missmatch.
    For example the Oracle database is release 9.2.0.4 and the gateway
    itself 9.2.0.1
    => The fix is to apply the same database patchset (gateway patches
    are part of the database patchsets) to the gateway home as well;
    or if the gateway 9.2.0.1 was installed into a 9.2.0.4 database
    directory to reapply the database patchset.

    Older gateways report this error instead of giving a

  • Question about transparent scroll bar?

    i have a Tree with some data in it. Verticalscrollpolicy = "ON". HorizontalScrollPolicy = "ON".
    When i click on one of my branches it expands, making horizontal width greater than the horizontal size of the Tree. The horizontal scroll bar springs into action, but the vertical scroll bar is still disabled because the data hasn't expanded that far vertically yet.
    However, when the vertical bar is disabled, the text overlaps the vertical scroll bar, like the bar is clear or something. I don't want this. I want the bar to be opaque, so the text never shows through it, even when the vertical scroll bar is disabled.
    any ideas? thanks!

  • Question about images with transparent backgrounds in inDesign

    Hi,
    I've recently switched from Quark to inDesign CS5.5, and I'm trying to figure out how to do something that was easy in Quark but doesn't seem to work in iD. I'd like to colorize a greyscale image that has a transparent background. In Quark, I could import it as a TIF and then specify different colors for the image and background (which I could specify to be transparent). In iD, seems that the transparency needs to be included in Photoshop (which wasn't the case in Quark; the method worked for any greyscale TIF), and that I need to chage the color of the in original image if I want to keep that transparency. Also, from what I've read, the imported image works better as a PSD.
    Is this correct? Does the transparency and color need to be specified in Photoshop for me to have a transparent image? (The image is too complex to include a clipping path, and it's being placed on a photographic background, so I can't simply change the bckground image to a solid color to make it blend in).
    If this is the case, it's really disappointing--I was able to get some great effects in Quark using the other method. I hope I'm misunderstanding what to do, or there's some kind of workaround.
    Thanks in advance for any help,
    --Harriet

    ID will only colorize non-transparent grayscales or bitmap mode images. If you don't need continuous tone, saving in Bitmap mode will render the white areas transparent when you colorize ( if the frame itself has no fill color, else that fill color will show), but that's not much good if you need a true grayscale. Changing the blending mode of a colorized grayscle to Multiply will cause white areas to be come transparent, but other areas will multiply over any background, which may not be what you want, either.

  • Question about background colors

    Greetings folks,
    I have a question about background colors using a DW template in CS4.The page in question is here: http://www.webrevamps.com/dw/assignment11.html
    On the left nav, I want the background color to extend throughout the entire sidebar. Not just where the text is. What am I doing wrong?
    And actually the same question applies to the main content area.
    Secondly, behind the graphic where the header is.... in DW it shows as a black background covering the entire header area, but that is not the way it looks when posted online. What am I doing wrong?
    Thanks!

    On the left nav, I want the background color to extend throughout the entire sidebar. Not just where the text is. What am I doing wrong?
    Nothing.  THis question is asked and answered several times a day.  Google "faux columns" to see a slick way to make it look like you have fixed this.
    Secondly, behind the graphic where the header is.... in DW it shows as a black background covering the entire header area, but that is not the way it looks when posted online. What am I doing wrong?
    No idea.  It looks exactly the same to me in CS5, nor do I see any reason why it wouldn't look the same in CS4.

  • Question about cutting out an object/removing white background

    Hello,  I will start this by saying that I am very new to photoshop.  Any input will be appreciated.
    What I am having trouble with is cutting a part of a picture out and the resulting white box that comes with the picture cutout.  Here is what I mean.
    I make a selection out of a picture and cut it out from the backround, like for example cutting a person out of a photo.  I cut the person out with the magic wand and what remains is the transparent background.  I then save as psd.  I then place the image in INDesign into a publication with a background color of say blue and have no problems there with the cutout of the person blending into the blue background.  Once the psd image is placed in INDesign I can move the image around anywhere in the publication and it blends in perfectly.  So all is good up until this point.  Here is where my problem is.
    Say I want to paste this image into a website, like a dreamweaver page and say the website page has a blue background.  I go to insert, image, and select the image psd to insert to the page.  What happens now is that the image inserts cutout person with a white background box and does not blend in with the blue background like I want.  The same thing happens if I insert as a gif or jpeg.
    What am I missing here to paste the photo in and NOT have this annoying white background?
    Thank you in advance for help!

    In Photoshop use File > Save for Web & Devices and choose the GIF or the PNG format.
    Note that the PNG has two versions, 8 bit  or 24 bit.
    Check the tranparency checkbox.

  • A few questions about Canvas and other Image related stuff.

    I am just starting to play around with Canvas in the hopes of using it to make a little game (not an applet) in my spare time. I have gotten a ball to bounce around the screen and switch colors when it bounces without too much work. (hooray for me!).
    I was wondering:
    1) If you always have to repaint the whole area of the canvas, or can you repaint sections of the screen?
    2) Can there only be one canvas per frame, or if you can have more, like say, one for each sprite (I tried in my own simplistic way but the second canvas overrode the first when I added it to the frame) or do you have to lay out all the sprites in one canvas every time before you paint?
    3) Is Canvas the best platform for rendering my animations and doing collision detection, or are other ways of presenting the images better? By better I mean lower usage of resources, higher speed, accessibility of events that occur. (I have read in the mindprod java glossary "[Canvas] receives all the raw mousing events. Panels, in contrast, see only a few.")
    4) In a call to paint which tells it to display some images which are much larger than the frame the canvas is in, is time and effort spent working on those pixels that aren't displayed or does it take about the same amount of resources as for images that fit in the frame since the same amount of picture is actually displayed?
    5) Is there any convenient way to layers with canvas besides just controlling the order in which the images are painted. (I will admit I haven't searched for this information yet, because I just thought about it.)
    6) Is there any other information you guys would care to bestow on me?
    If any of this question is ridiculous, obvious, ignorant or any other negative adjective, then I apologize. I will continue messing around in the meantime.
    Thanks

    Okay, well I got it to work by drawing them both to the same canvas. duh I guess.
    Can you have more than one canvas in a frame? How do you set the size if so.
    How do I implement the z-order? I thought of doing it manually by sending the paint method a list of objects to paint and manually managing the order of that list. Would that be an acceptable way to do it?
    Should I only be trying to paint to one canvas? What I would like to do is have several canvases with transparent backgrounds so that I can draw different layers in the same frame. That way flying stuff would be painted on a different canvas than stuff on the ground, and then putting it all in a frame would tie the pictures together into a scene. Kind of like how they do distance in animation by having different layers of drawings on clear plastic that they can move at different speeds to give the illusion of depth.
    Any advise? Sorry for the douba-post
    Thanks

  • Combining 100 pngs with transparent background, vertically into one image PSE9

    As the question suggests,
    In PSE9 is it possible to combine 100+ PNG files (with identical dimensions & transparent background) into a single PNG file where the images are stacked vertically? and without trimming/cropping the transparent part of the image! I want to retain the exact original image dimensions so that they all stack neatly and precisely. 
    So far what I've tried is opening up the 100 PNG files in PSE9, create a new document with transparent background using the same width as the individual files and the height set to the individual file height multiplied by 100. (i.e. original image is 36 x 120 so the new file will be 36 x 12000) Then I get stuck! Whenever I drag a single file into the newly created document, it seems to be cropped to the image edges and no longer retains it's original height and width. Not to mention that hand dragging 100 files seems like a long-winded way of doing things... My automate button seems to be greyed out (so no contact sheet?) and I can't find any other automated process.
    Any help would be greatly appreciated,
    Thanks

    Please compare the resoultion of the two documents too. And a better way of arranging the layers would be to use distribute option in the move tool. You can find more about the move tool at http://helpx.adobe.com/photoshop-elements/using/moving-copying-selections.html#main-pars_h eading_0
    Thus your workflow would be:
    Create a new document with the required dimension.
    Use File>Place to place all your png files on the created document as layers
    Use distribute option in move tool
    A still better workflow would be to use put all the files in a folder and write an ExtendScript to read the files and place them as layers on the document of said dimension

  • Printing Images with Transparent Background

    Sorry if this question has already been asked, but I couldn't find anything similar to it in a search through the archives.
    I have a couple of images with transparent backgrounds in a document, much like the shells and the blue flowers in the "Classic Brochure" template in Pages 2.0.1. These images show up perfect on the screen, and when printed as .pdf files, but when I print to either an hp color laserjet 4600 or an hp laserjet 1320, the images show up with a clear box around them; the colors under the box (where it should be transparent) are faded and slightly blurred. This happens both with my document, and the unaltered "Classic Brochure" template. I've tried moving various objects backwards and forwards, but it doen't seem to have any effect. It even happens with one of the text boxes I have in the document.
    Another odd thing is that the printed "box" isn't the same size as the box that appears when you click on the object in the document. It's a bit bigger. I've seen other posts about problems with hp printers, but I'm not sure it's related. Any insight would be appreciated.

  • Transparent Backgrounds

    This is a beginner's question. I am using Illustrator v.10. I am just trying to produce some text that has a drop shadow and a transparent background. I want to export to a jpg file and put it in a website header so the gradient of the header with show underneath the text. I have no problem with the text, or the drop shadow, but how does one create a transparent background? Do I need to create a layer just for the background, and make it transparent? How would I designate a layer as "the background". I haven't seen anything in Illustrator about "background".
    I would appreciate any help you can provide.
    Thanks.

    What Rob said, unless the image is supposed to fade into a background of varying colour; in that case, tick the Anti Aliasing in the Image Window in Save for Web, tick Transparency, and set the Matte colour to an average value of the background colour.
    You can find the hex colour values by choosing Web Safe RGB in the Color Window.

    I'm no expert, though, but it seemed a pretty clear reply saying you can't do what you want to do. But I wouldn't put much weight on what I think about that point.

    I go to HELP, FORUMS, etc...I get no response or HELP directs me to  a page about  some other software. SO my question is: how do I create a transparent background?

    Thank you, that was a tremendous help. There must be some way of typing in a topic and one gets presented the proper page in the HELP section, but I keep being redirected to  pages for other software or pages that have no correlation to the topic I have asked about. May I ask, do you have any insight as to how I can navigate my way through?
