Problem with colors

hi friends,
iam new to java. iam developing gui using swings. i have menus,buttons in my main page. i had given some background colors to all components. when i placed on any component, some back ground like main page is seen. how to avoid this problem. if any body aware of this problem please help me.
thanks
sriram

Why not use each component's default background and foreground colors? If you have to set different background and foreground colors for your components, make sure that each component's setOpaque(false) method is called.
However, I think its natural for the background or foreground to be seen if your top components do not take up the whole size of its container.

    Hi
    I have a problem with color prints from photoshop elements 12. The pictures are too light and with strange colors. I have a Canon pixma mg615I0 printer and use mac os X yosemite. The pictures are taken with a coanon eos 550d in the color space sRGB. I have followed adobes recommendations and have tried both letting the printer respektive photoshop manage the colors. But nothing works. I see that there are different opinions about which is best to do so I tried both. I have the latest printer driver installed. Can anyone help me with this?

    Do the following:
    Print a test page from the printer. Perhaps the print head needs cleaning via its maintenance facility.
    Let the printer manage colors, not PSE

  • Problems with colors running CS4 and W7.

    Hey everyone.
    I'm having some MASSIVE problems with colors on my system.
    Windows 7 Prof 64bit
    Photoshop CS4 64bit
    6g Ram
    1T hard drive
    Nvidia GeForce 9800 GTX+
    Dell SE198WFP Monitor 
    The system itself is a Dell Inspiron 530 that I put into a Black Widow V9 gaming tower. 
    Here is an example of the issue I'm having: 
    http://findae.deviantart.com/art/Converge-101214480
    http://i38.tinypic.com/bjcymr.jpg 
    The top image is a (admittedly old and crappy, but it shows the problem) photo that I had previously edited and put in my portfolio. The tinypic below is the result of copying that photo from the portfolio, pasting it into photoshop, and then saving it into a jpg. As you can see, the transitions between colors and the contrast are a complete mess. 
    Thing is, my hard drive recently quit on me, and I had to install the operating system and such on a new drive. I remember having this problem with the system when I first had it, but it either went away on its own or I fixed it somehow before. Now I can't remember for the life of me how I got rid of the problem, and I certainly don't know what the problem is in the first place. I'm tempted to think it may not be photoshop itself, but the problem seems to be especially bad when I'm working with photos. 
    Anyone have any idea what the problem might be and how to solve it? 
    Edit: I also noticed it when viewing http://findae.deviantart.com/gallery/#/d1hni37 in firefox, whereas the other photo appeared to be ok before I copied and pasted it. It has extremely obvious lines of green and orange in the transition from light skin tone to dark skin tone. Annoyingly enough, this doesn't show up in the thumbnail within my gallery at all, only when I click on the thumbnail and see the fullsize image. Extremely frustrating.  
    Here's another good look at the problem while selecting a color in photoshop: http://i37.tinypic.com/2h6t7gh.jpg  All I did was screenshot it a few times, and it deteriorated to that point.

    Screen glitches like color blocks appearing where they shouldn't could indicate a problem with your video drivers.
    Go to the nVidia site and see if they've released any updated drivers; people often report that updated drivers are correcting current problems with Photoshop.

  • Problem with colors showing in PE10

    Is there a known problem with color in Elements 10?
    I have a gif that when opened in paint shows the light blue color correctly but in PSE10 shows as a buff color.
    Red, yellow and blue seem about right.
    It doesnt matter if it is the gif or the psd file the color showns the same in PSE10.
    Is there a setting or could something be corrupted.

    Bump.
    I have uninstalled and reinstalled Elements and get the same result.
    Is there a way to adjust the colors represented in Elements 10?

  • Strange problem with color measure in Mac.

    Hello, I am having a strange problem with color measure in Mac. For example i create a gradient in Photoshop from color 200 200 200 to color 240 240 240. When i measure the color of the gradient with the color measure tool of Photoshop or with the built in OS X color measure tool the measured color is from 200 199 197 to 240 240 238. I have measured the same gradient with Photoshop for PC and the values are OK (the same values that i create).
    I dont know what is the problem, but i belive that the colors that i create would be the same that i measure after creating them, and also the same values between Mac and PC. I will appreciate it a lot any help or information that you could give me that helps me to understand what is happening here.
    Thank you for your time
    Marcelo.

    Yep you got it, proof as monitor basicaly strips out any profiling and just delivers it straight.
    is there any way to make the OS X color measure tool to measure the original color values
    You mean the document colors - No, like I said photoshop is filtering your image through document profile, proof setup and monitor profile. Why do you want to use Digital color meter anyway for this?
    i dont understand what is the point to measure color values that will change every time a calibrate my monitor.
    Because color values are 'bigger' than whats on your monitor. Your monitor (via photoshop) is only doing the best it can to display those values - which can be anything from LAB colors outside the gamut of your monitor - to CMYK colors. Calibrating it is the only way to allow your monitor to do this in any way accurately. (not ever really possible) Monitors have a certain gamut and are only dispays/representations of the REAL colors that a document, with a profile, holds. So there's only one good reason to measure monitor values, and that's to generate a monitor profile.

  • Java update causes problems with color printing in Mac 10.5

    Had a big problem with color printing for the last two weeks. Thought the printer was broken because it would freeze and refuse to be "seen", or would generate error messages. Bought new Samsung 315, and had the SAME problem. Bought new HP CP1518ni, and had the SAME problem. Not resolved after talking to tech support at both places.
    Looked for software updates around the time of the onset of printing problems. on May 15 installed "Java for Mac OS X 10.5 update" (1.0) (am running on 10.5.8). Removed the Java preferences files (com.apple.java......plist) and restarted.
    Problem solved! Clearly not the printer.

    Hmmm. This is about the time my printer stopped printing too. I've now had two printers in my house and had trouble with both of them. What a pain we should not have to delete updates for our stuff to work together.

  • Problem with colors when print to pdf in FM9

    Hi,
    we have some problems with printing colors to pdf with FM9.
    The FM document contains (1) eps file with a green box and (2) a rectangle created with FM graphic tools, filled with the same green color values (91/0/60/44)
    In FrameMaker the two colors really looks different, but so what, in the PDF both colors (eps) and rectangle got the same correct green color.
    Ok, the were different in creation, so they were CMYK and RGB, but your print shop could manage that.
    Now in FM 9:
    (1) If I do a "save as PDF"  and switch OFF "convert CMYK to RGB" the resulting PDF is the same as from FM8 (correct)
    (2) If I print to PDF via distiller and define the job options to "convert all colors to CMYK" the resulting rectangle green is very  different from the eps green.
    I tried different job options, the best result was "convert all colors to CMYK", other options just very more ugly.
    Does someone of you know a solution for your problem? Help is very appreciated. I could send example files if necessary.
    Thanks in advance.

    Pia,
    this last sentence needs some explanation, I think. Why do you want to use the print option?
    Using the print option, you still go the same route as FrameMaker Win always did, which is using the RGB-only Windows postscript driver. Now, with FM9, you have the option to get CMYK colors directly to PDF, as defined, without any color conversion. And it *does* work, as long as you restrict your documents to either CMYK colors or spot colors coming from the FM libraries.
    So, again: why do you want to use the print option?
    On a sidenote: I'm not sure if I interpret your username correctly, but if you are able to understand German, you'll find some in-depth color tests made with FM9 here: http://www.hilfdirselbst.ch/foren/FM_9_und_Farben_in_PDFs____getestet_P387800.html

  • Problems with color matching when printing...

         Hi, I work for a small family business in the P.O.P. industry.  We currently have myself and one other designer, we both take illustrator files that have come from the graphic design firm that we contract with and get them ready to print on our Vutek QS3200.  However ever since acquiring the printer we have begun to run into problems with the colors when printing.  When the files are exported off of my computer, I use either .tif or .pdf files, they print as they should, the colors seem to match the proof and everything goes smoothly.  However when the other designer exports a file, he tends to do mainly pdfs, the colors tend to be extremely different from where we want them.  Also we will get very strange results, such as yesterday he kept getting a faint yellow 1/2" border around his prints.  After I believe 3+ hours of him trying, I was given the original CD and instructed to try.  After 15-20 minutes of making the changes that we needed to make (adding a new price point) and ripping, mine printed perfectly. 
         We both use Macs, both have CS3 Design standard, only differences between the computers are mine is newer and a bit faster, and I'm running OS 10.5.6 and he has 10.4.  He has also at some point loaded various color profiles, whereas my CS package is just whatever the default is when I loaded it.  When we were being trained he grabbed the color profile off of the Colorburst RIP server and loaded onto his computer, plus I believe he has a couple for freelancing purposes on there as well.  My thought is that these profiles are somehow corrupting the files that are going through that computer, but I honestly am lost with it at the moment.  He believes the problem lies within the fact that he does not have the newer OS, I honestly cannot see that as having any effect on this at all.  I was wondering if anyone has run into any similar problems, or if anyone might have any advice on this issue?  I would really like to be able to solve this, as I was hired to do mainly structural design for the P.O.P. and I'm having to put in a lot of overtime to get my work done along with the additional work that I'm having to do.
    Thanks for your time

    I've got a few years experience calibrating large format printers.  First, the Yellow sounds like a file problem.  I used to work with two workstations, one PC ( RIP station ), and one Mac ( file prep station ).  I tend to agree with you in that the OS is probably not the problem.  But, any Colorburst profiles should remain in the RIP, not in the originator application.  My workflow consisted of creating EPS files that were based on established color settings in their given applications ( i.e., Illustrator, Photoshop ) which were interpreted by the RIP which had it's own calibrated profile ( perhaps more than one based on how many different substrates were being used ).  Your partner may be complicating things by incorporating a RIP profile prematurely.  If there are deviations big enough to be noticed, there has to be something in the application color settings that is causing some type of corruption.  This could lead back to the operating system, but I would think it lies somewhere in Bridge or the application color settings.  Start there.  You should seriously consider implementing a calibration system if you do not have one already.  Another slight possibility is the driver's ability to interpret files coming out of Leopard vs. files coming out of Tiger.  It may benefit you both to be in the same operating system dynamics, using the same driver versions and RIP profiles.  At the very least, match everything that is currently working successfully and put them on both machines.  If there is still a noticeable problem in color matching, then something is seriously wrong and you should call in a prepress profiling expert.  Hope this helps.

  • 4400F scanner has problems with color slides

    About six years after buying the 4400F scanner, I finally opened it today in order to start scanning a lot of color slides going back more than 40 years.  It seems as if the software (or the scanner itself) doesn't know where one slide ends and the next one begins.  The slide holder accommodates up to four slides.  Using several methods of scanning permitted by the software, I obtain either three or five JPEG scans.  In the case of three, the images are properly centered--only the final one is missing.  In the case of five, the images are all off-center.  
    Has anyone had a similar problem with this unit and the software when scanning slides?

  • Adobe Photoshop CC, problem with color noise/pixelation on the monitor display

    After downloading Adobe Photoshop CC, my images come in with color noise/pixelation on the monitor display. I've tried checking the color space preferences, but this doesn't help. I didn't have this problem before. Is there anything else I can check? There's no problem with LR, just Photoshop.

    My performance settings are: Available RAM 10905 MB/using 7633 MG (70 percent); cache levels 4, history 20, cache tile size 1024K. However, I noticed under Graphics processer settings, it is set on Advanced Drawing Mode - perhaps this should be changed to Normal or Basic Mode? Your help is very much appreciated.

  • Problem with Color conversion ADM_Color to  AI_Color

    Hello friends,
    I think this is going to be the first post in this "Illustrator SDK Forum".
    I am having problem with 'Setting Art Work Colors'.
    I am trying to get the color value from the user through a ADM dialogue window, using the function
    sADMBasic->ChooseColor();
    The function is returning color in
    ADMRGBColor structure, whose members (
    red, green, blue) are of the type
    'short'.
    Now, I want to print a rectangular box art filled with that 'user selected color'.
    But the color I have with me is in the
    ADMRGBColor(each member of type 'short') and to draw that on a illustrator file, I need the type
    'AIThreeColrStyle'(each member is of the type AIReal).
    I had no idea how to convert
    ADMRGBColor to
    AIThreeColorStyle, but after lots of 'trial and errors', I arrived at this 'crude' solution.
    ADMRGBColor value was in the range
    0-65535 and
    AIThreeColorStyle was in the range
    0-1
    aiPathStyle.fill.color.c.rgb.red = ((float)admColor.red)/65535;
    This conversion was working fine on Windows, but on Mac its giving weird results. Can some one tell me the proper solution for this conversion problem?
    Thanking you,
    Vijoy~
    And thank you Adobe for givig us this "Illustrator SDK Forum".
    Forums Operations "Why there is no SDK forum for Illustrator?" 12/13/04 4:21pm

    The code above seems to work for me. I get the proper values in the rgb fields of the AIPathStyle struct. Are you sure you are filling in the remaining values in the struct (like fillPaint, overprint, etc.) with appropriate values?
    Hope that helps,

  • Problem with colors and bits

    So I have this problem, I made a drawing with my tablet in 32bit color in photoshop and I want to save it as a TIFF file, but when I save it the image that is the tiff file is black and white and the cuality is not good.I think there is some kind of problem with the RGB color.If someone can tell me how to fix this ?
    Also when I try to change the image to 16 or 8 bit(so I can save it as a JPEG file), it looses all its effect like details made with brush with low opacity.I really hope someone can help me out

    Just to be clear, 32 bit color (when used with an RGB image) is 32 bits each for red, green, and blue = 96 bits / pixel.
    The use of images carrying 32 bit color is uncommon, and this format is used primarily in editing to deal with High Dynamic Range imagery.  I suspect whatever tool you're using to view the TIFF you saved with 32 bit color is unable to deal with the format, which is why you're seeing it looking poorly and in black and white.
    Your instinct is correct to reduce the bit depth to save in a more common format.
    However, you should not be seeing a visible degradation when reducing the bit depth to 16 bits / channel.  That's still a very accurate format.  How are you "changing the image to 16 or 8 bit", specifically?

  • Problems with color from Photoshop to InDesign CS2?

    Hi all,
    Couple of questions:
    When I select "Proof Colors" from "View", the color changes a little bit. Is this normal?
    Also, on "View", "Proof Setup", which one should I select "Document CMYK" or "Working CMYK" or some other "Custom"
    thanks for all your help,
    Alex

    >When I select "Proof Colors" from "View", the color changes a little bit. Is this normal?
    It's not abnormal, but it will depend on what color spaces the objects are in and the color space that you choose to proof.
    >Also, on "View", "Proof Setup", which one should I select "Document CMYK" or "Working CMYK" or some other "Custom"
    You have a lot of choices for how to set up color management. I usually leave my settings set up for my most common situation, US Sheetfed coated and Adobe RGB, but if I have a special job I can reassign the document color space (notice I said Assign, not convert, in order to preserve the native object color numbers). You can proof the color in either the Working CMYK (the one in the color settings) the Document CMYK (if that's different) or something else entirely if you are repurposing an existing document for a new output method.
    When you proof colors, InDesign calculates the conversions on the fly and displays the results. RGB objects will almost always show some shifting due to gamut differences, but the type and degree will depend on the rendering intent you specify. CMYK objects tend not to show as much shifting because the gamuts are likely to be closer, but again it will depend on the exact profiles and intents. Objects that are already in the chosen proofing space should not show any shift at all.
    There is a caveat here regarding working in one space and outputting in another: If you want the colors to be as close as possible you will be converting to the new profile, which will by necessity change some color numbers to match the appearance. This is not usually a problem with things like photographs, but other things, like type, which is created as 100% K can be converted to a four-color mix which is not good. If you know the output conditions, I always recommend setting the document CMYK to that space when you start.

  • Problems with color quality when saving photos.

    I never used to have any problems, but just recently I have noticed that, after cropping, editing, resizing my photos, and saving....they look fine on my screen while open in photoshop, but yet when attaching them and emailing or posting them, the color quality seems to change. The photo ends up looking quite different than my original photo (the edited copy). I can't figure out for the life of me what is causing this and do not remember ever having this problem before. The only thing that has changed is a new monitor. I don't think that would have any bearing, because like i said, everything looks great until the photos are sent. (when looking in my sent folder, i can see the "altered" state of the image. it's not just a problem with someone elses computer settings, etc)
    A newbie here with low tech skills, lol. Any help is appreciated, I would just like my pictures to be seen by others in the color state and quality as they appear to me, and it is frustrating.
    I hope my explanation of my problem makes sense and look forward to any advice. (I'm hoping there is a quick solution like a setting I need to click on or off!??)
    (using Elements 2.0)

    Hi Amy:
    Sorry that the Color Setting idea didn't do the trick. Since the occurrence is separate, that is, seeing one color view using Elements and a different color view using email view. I still suspect this area.
    Calibrating a monitor to me (as the saying goes), is easier said than done. You may want to do a web search using Calibrate Monitor, or similar search words. This will find some interesting websites on calibrating monitors you can read and try out. If you do change some settings, write down what your original settings are before hand, so if you make it worse, you can go back where you started.
    There are two areas to calibrate the monitor.
    1. Using the monitor controls on the monitor itself.
    or/and
    2. Using the graphics card (software) control. Which is normally found (Win XP) DISPLAY PROPERTIES>SETTINGS>ADVANCED> then the TAB with your graphics card name.
    3. Actually there is a third one, which uses a very expensive device that connects to the monitor. At the moment this method escapes me. Mainly used by professionals and serious photo editing people.
    Good Luck!

  • Problems with color display

    I'm having a problem with managing color display from Aperture - I have a similar problem with Lightroom so I suspect there is something messed up somewhere that I don't understand.
    I've been processing RAW files from Canon 400D. I color adjust in Aperture and then export as JPEG. the resulting files had a red/orange cast when viewed in Preview. Interestingly the same red/orange cast appears when I switch Aperture in full-screen mode! If I import the JPEGs into iPhoto they have have the cast - however the cast disappears (and the color goes back to what I expect) when I go into Edit mode in iPhoto. It looks like JPEGs from Aperture has sRGB profiles assigned. Exporting as TIFF doesn't help.
    A similar things happens from Lightroom, ie the colours look right in LR, but exported JPEGs get the same red-orange cast when viewed in Preview whether I assign sRGB or AdobeRGB.
    Photoshop and Graphic Convertor appear to display the images correctly.
    It seems to me that the FInder, Preview and the full screen mode in Aperture may not be using color profiles accurately?
    Any suggestions would be greatly appreciated!

    Update:
    I've checked this:
    -Aux (Dock-Connector) of the iPod has no damage, no problems playing music in the car!
    -Same Problem now with iPhone. It gets charged and so, but if I want to listen to music it is very quiet, music is playing for half a second or so, after that stopped, than goes on playing for a second or so. Cracking sounds often while music is stopped.
    So the Dock is broken, I guess.
    Any possibility to restart/resert or so by my own or try to get it fixed by apple?

  • Problems with color tools

    Hi All,
    I had my CS4 installed in my office computer and it was working perfectly.
    A couple of days ago I decided to deactivate from that computer and install it in my home computer. Now I am experiencing problems with the color tools. For instance, in the brush tool I can only select colors from the palette. If I put the select color tool over an image, it does not "read" de color It is not "reading" the color. It changes the tool to black.
    Any idea why this is happening?
