This message is really urgent. I'm deploying an application with Forte and I'd just like to insert an image as simple as I can. But the error message is :

that I put in the constructor. I verified all my path en classpath but no result and I don't why?
If somebody could help me ...
Thanks

Thanks for your answer but I found the solution. In fact my image is in a package (the same repertory as sources) but I had to write Pack/...png but I don't know why. Maybe it will help someone else.

  • Many images in wikipedia are not shown. Typically some are greyed-out, and are of the form data:image/png;base64,iVBORw0KGgoAAA

    Most images in wikipedia are not visible. Icons are ok.
    Looking at page info, the greyed-out ones are of type Background in the list and type PNG Image in the text below them.
    Example:

  • Can't load large image (png)

    I have a sandbox web page with large image (png file 26000x13000, 14MB packed/330MB unpacked). I can open it in IE but firefox display page without image. I have 1,2GB of free RAM, how can I adjust settings to make allow firefox display the image? Currently there is no difference if I use unpacked BMP, it doesn't work as well. I would prefer to stay with PNG since it's only 14MB on disk.

    Is there an error message?

  • RE: (forte-users) Hi All....very urgent...Forte doesn'thandle La rge ar

    Okay, here's my three cents worth,
    Are you using Forte "Keep Alive" settings? If yes, you may simply have a
    time-out.
    While a partition is waiting for a reply from a database, it blocks and
    won't respond
    to anything, including pings to check if it's still alive. So, if the query
    takes longer to
    complete than the time-out period of the communication manager, then you
    will
    loose the connection to the partition.

    Hi,
    This sounds almost identical to a problem we have experienced.
    If it is the same problem it is because you have compiled a back-end
    load-balanced partition, but NOT the router that manages it.
    With such a configuration, attempts to send greater than a few thousand
    rows
    will fail - and it doesn't seem to matter what you set -fm to.
    You don't see the problem running distributed from your workspace because
    everything is interpreted.
    So just compile the router and try again.
    Hope this helps.

  • How to remove banding from exported images (png, tiff) from illustrator layout with gradient

    is there any way to remove or reduce banding that I am getting in a layout I've done that contains a gradient? I am exporting raster images (png or tiff) and there is a noticeable stepping of tonalities, rather than a smooth shift
    thanks

    In an 8bit format like PNG you only have 1024 unique levels...
    1024 is 10 bits. 8 bits is 256.
    But PNG is an RGB 8-bit per channel format. That yields 256^3 (i.e.; 24-bit or 16.7 million) potential "levels" (colors).
    ...banding that I am getting in a layout...
    Banding that you are getting where?
    What are the specific color values involved?
    What is the final use?
    What will be the distance across the gradient in its final use?
    You have to consider whether the banding is actually in the raster image, or if it is merely an artifact of where/how the image is being viewed.
    Banding is not a simple matter of image color depth. Banding is a device-dependent phenomena. The banding you see on your monitor is not the same banding that will be seen on your grayscale laser printer; is not the same banding that will be seen on your CMYK inkjet printer; is not the same banding that will be seen on press. Banding in print is generally more a function of levels of gray (per separation) of the imaging device, and can vary depending on the halftone ruling (assuming conventional AM screening).
    Depending on the answers to the questions above, you may very well be fretting over nothing.

  • Loading images in Forte 4J CE

    When i load an image to an applet using Forte for Java CE 4 and run it ,the applet crashes giving an error message saying access denied to the images.How can i add images using Forte and make it run properly because i want to program games

    Unless it is signed, your applet does indeed need to follow the sandbox security model. If you wish to use images, you can download them from the same website the applet came from (this is possible in the sandbox) or you can also add your image to your JAR file and retrieve it using:
    applet.getImage(applet.getCodeBase());or
    applet.getImage(applet.getDocumentBase());Security restrictions are described here:
    http://java.sun.com/docs/books/tutorial/applet/practical/security.html
    See here for more info on loadingimages in applets:
    http://java.sun.com/docs/books/tutorial/uiswing/painting/loadingImages.html

  • Saving and loading images (png) on the iPhone / iPad locally

    Hi,
    you might find this helpful..
    Just tested how to save and load images, png in this case, locally on the i-Devices.
    In addition with a SharedObject it could be used as an image cache.
    Make sure you have the adobe.images.PNG encoder
    https://github.com/mikechambers/as3corelib/blob/master/src/com/adobe/images/PNGEncoder.as
    Not really tested, no error handling, just as a start.

  • How to disable Data URI (data:image/png;base64 URI)

    Hi all,
    I'm not sure when it started, but when I want to view an image's URI in my Safari 5.0.4, it gives me the "data:image/png;base64" URI, instead of the usual "http://example.com/image.jpg". Is there a way to disable this? I need to check URI's of images regularly and this is quite a pain.
    Thanks for your help!
    Keywords: Data URI Scheme, image url, image uri, image address, data:image

    Hi Andy, thank you, I had Deanimator 0.3.0 installed, and once I disabled it and restarted Safari, the problem went away.
    Guess I'll have to choose between being able to view "normal" uri's or not letting animated gifs slow my Safari to death. LOL.
    Thanks again!

  • Afficher une image png sur face avant

    Bonjour,
    Je cherche à afficher une image .png sur la face avant de mon vi. J'ai bien trouvé plusieurs exemples sur les forums mais tous utilisent des containers.
    J'aimerais juste afficher l'image en elle même sans avoir de cadre autour... (j'ai rajouté l'icone verte sur le print screen en faisant un copier-coller mais il n'est pas possible de la rendre invisible).
    Le but final serait d'afficher telle ou de rendre invisible cette image.
    Cela est-il possible?
    J'utilise LB2010 ou 2009...

    Bonjour,
    Tu peux aussi utiliser un picture ring de la palette classic, et rendre le cadre transparent. Tu importes ton image en laissant un item vide. Tu n'as qu'à changer la valeur pour afficher ou non l'image (ou utiliser un noeud de propriété visible fonctionne aussi).

  • Probleme pour lire une image png et transparen​ce

    Bonjour,
    mon objectif est de régler la transparence d'une image png, pour cela j'ai trouvé le vi "Create a mask by Alpha" mais le problème vient de la lecture de l'image. Je lis une image .png en utilisant le vi "read pgn" file puis "Draw flattened pixmap" et je n'obtient pas l'image en entier. Vous pouvez le voir sur l'image (j'ai fait un impr écran de la face avant), il manque le bas de l'image par rapport à l'originale (image simplement importée depuis le menu edit/import picture to clipboard).
    En cherchant sur le forum j'ai obtenu des Vi (sur cette discussion : http://forums.ni.com/t5/LabVIEW/how-to-get-alpha-i​mages-on-picture-box/m-p/1138513#M501588) qui me permettent de bien lire les image .png. En les utilisant l'image est entière (c'est celle marquée with alpha) mais par contre, je ne peux plus utiliser le vi "Create a mask by Alpha" car le cluster qui contient les data image ne sont pas les même.
    Donc j'aimerais savoir pourquoi l'image ne sort pas en entier lorsque j'utilise read png file d'une part.
    D'autres part, je voudrais savoir que faudrait-il modifier sur le vi "Create Mask by Alpha" pour que je puisse régler la transparence de mon image tout en utilisant les vi trouvé sur le forum?
    Je ne sais plus quoi faire...si je ne suis pas claire il y a mon vi en pièce jointe.

  • Problem: List images / Palm / Forte

    Are there any issues with creating JAR files that contain PNG files with Forte?
    I cannot seem to get images to display in a List on a Palm. With the Forte debugger, I am able to see that the Image is found. No exceptions are throw when I try to get a handle on the PNG.
    When it comes to displaying the image, the default list icon is displayed instead.
    My image is a black and white, 10x10 PNG image. It is 1kb in size.
    Has anyone experienced this problem? If so, how did you solve it?

    [kevinsikora],
    Not that I know of. With the MIDP 1.0 for PalmOS, there is a restriction of the maximum image file size of 64 kbytes for a PNG image file.
    Can you check the Preferences settings on the "Java HQ" AMS application? There is a setting for the color for the MIDP for Palm OS 1.0 environment, that should state black and white since your PNG image is black and white.
    Can I assume that you are using the Image.createImage() method in your code and that the PNG file is placed correctly in the JAR file?

  • Importing an Image (png) into a designated (Coordinated) location.

    Greetings,
    I'm currently developing a TicTacToe application. I am using an array to store the points (Coordinates) of where I would like an image to be input when I call a paint method. Eg An O in position 1 would use the coordinates associated with the grid element (Stored in the array) for 1 to paint the image:
    1|2|3 O|2|3
    4|5|6 --> 4|5|6
    7|8|9 7|8|9
    I have all of the x1,x2,y1,y2 coordinates, and this is a two part question...
    1. Will one of the createImage methods create an image using an existing png but resize it to fit between the desired coordinates?
    2. And if not, could you suggest an alternative method to accomplish this?
    Regards,
    RakeOne.

    1. Will one of the createImage methods create an
    image using an existing png but resize it to fit
    between the desired coordinates?I don't know about this.
    2. And if not, could you suggest an alternative
    method to accomplish this?I would do this by manually drawing X's and O's on the canvas,
    since you already have the coordinates, this shouldn't be hard.
    Or by having three images, one for X, one for O, and one empty.
    Every image would have the background color you wish and a
    border, which will become the grid when the images are next to
    each other. First fill the canvas with nine empty images, and
    when X or O is inserted in some location, replace that image with
    corresponding X/O image.

  • Adobe Assets: PSD export to image(PNG, JPG) crashes webpage

    Firstly it is great that Adobe Assets was released so that it would be possible to view PSD files.
    Have a PSD file opened in Adobe Assets on Google Chrome(Linux). I am trying to use the option of exporting the PSD to an image format, but the Actions -> Download -> PNG/JPG crashes the webpage.
    Any workaround other than using Adobe Photoshop? I guess I can ask the creator of the PSD to export it.

    Did you use the camera app to take the photos or an third-party app. I just ran into the same issue this weekend. When I was using Facebook, I took some photos within the app and they showed up as .png. When I used Apple's camera app, they were .jpgs. Curiouser and Curiouser.
