How to read local large JPEG files and display into Images Tile

Hi all,
I can read the local multiple files by FLEX/AIR FileListEvent
and loader to read the large JPEG files but cannot display them
into a TileList. Since it is a number of images files, how can I
put them into a thumbnail TileList.
Please kindly advise.
Regards,
Billy

1. So I would like to know which is the {color:#3366ff}best way to load local images in ImageView{color}.I'm no expert, but is there a reason that you are using Swing to do the loading?
2. secondly, currently the system displays all images only after the completion of creating all images. {color:#3366ff}How to display images as and when they are created.{color} So that the user has a feeling that the images are loading.JavaFX Image class let you display a lightweight placeholder, and you can bind the progress to some kind of visual indicator. I don't think you can display an image that is partially loaded.
def PATHS: String[] = [
    "C://Ariel Atom//ariel-atom-1.jpg",
    "C://Ariel Atom//ariel-atom-2.jpg",
    "C://Ariel Atom//ariel-atom-3.jpg",
    "C://Ariel Atom//ariel-atom-5.jpg"
function getImage(path: String): Image {
    Image {
        url: "file:///{path}"
        backgroundLoading: true
Stage {
    title: "Image Tiles"
    width: 1024
    height: 800
    scene: Scene {
        content: [
            Tile {
                columns: 2
                tileWidth: 400
                tileHeight: 400
                content: for (i in [0..3]) {

  • Parsing large xml file and display using swing

    Hi all,
    I want to read a large xml file and display graphically in swing as a tree structure.
    I implemented it and works fine for files of 5MB size after increasing the jvm heap size (-Xmx). If the file size is larger than 5MB it throws out of memory error. I'm creating a custom datastructure from the xml and I'm using sax parsing.
    After displaying the datastructure, the user could do some operation on this, like search etc.
    Can any of you suggest a method, to support larger files ? What I'm looking for is create the datastructure in file system, rather than in memory.
    Any other tips for memory management would be greatly appreciated
    Thanks in Advance.

    How do I transfer my catalog, files and collections into Lightroom 4 onto another computer?

    You can copy your image file  from you PC to your Mac over your home network or via DVD/CD.  You can not install you PC CS5.1 version on you Mac. Its not compatible with MAC OS.  You would need a MAC version of CS5.1 and Mac version serial number to activate it.  Adobe no longer markets CS5 so you most likely will not be able to pay for a platform switch media install.

    Hi Firepros1,
    You may try exporting file as PNG or TIFF instead of jpeg.

  • Reading from a text file and displaying the contents with in a frame

    Hi All,
    I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
    pcode1,pname1,price1,sname1,
    pcode2,pname2,price2,sname1,
    I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
    Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
    void ReadTextFile()
                        FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                         InputStreamReader isr=new InputStreamReader(fis);
                         char[] buf=new char[1024];
                         isr.read(buf,0,1024);
                         fstr=new String(buf);
                         String Tokenizer st=new StringTokenizer(fstr,",");
                         while(st.hasMoreTokens())
                                          pcode1=st.nextToken();
                               pname1=st.nextToken();
              price1=st.nextToken();
                              sname1=st.nextToken();
         } //close of while loop
                    } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
    Thanks in advance.

    If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
    MyClassName.pcode1;
    MyClassName.pname1;
    MyClassName.price1;
    MyClassName.sname1

  • How can I use a JPEG file as a background image for my vi in 8.5

    Im working on a vi that I plan on using as part of an alarm system.  I would like to use a JPEG file of my house as a background image for the vi, or possibly to just be displayed in a window on the control panel.  I have seen people use their own images before, but never looked at what this involved.
    Im trying to use the "read JPEG file" vi and the "draw flattened pixmap" vi to accomplish this.  The vi does run, but nothing shows on the front panel.  If I try to create an indicator from the "new picture" output of the "draw flattened pixmap" vi, I get an empty white window on the front panel.
    Any advice?
    Thanks

    the earlier vi (using the JPEG) works fine. just increase the size of the picture control
    I figured this was the problem. And to the OP, I'm glad a bitmap worked, but no I didn't mean use any sort of LabVIEW programming at all. I meant open your image in Microsoft Paint, Press ctrl+A to select the whole thing. Then copy the image to the clipboard. Now select your front panel and press ctrl + v to paste it. No programming needed and the image is there. However, if you want to programmatically change it, you will need a picture control.

  • Reading a Blob (CSV file) and displaying the contents

    Hello Experts,
    I’m currently working on a system that allows the users to upload an Excel spreadsheet (.xls) in the system. The upload page is a PL/SQL cartridge. Then I’ve written a Java servlet (using Oracle Clean Content) to convert the XLS into a CSV and store it back in the database. (it is stored in the “uploaded_files” table as a blob). I’m trying to create another procedure to read the contents of the blob and display a preview of the data on the screen (using an html table (will be done using cartridge)). After the preview, the user can choose to submit the data into the database into the “detail_records” table or simply discard everything.
    Can anyone provide me any guidelines and/or code samples for reading the contents of a blob and displaying it as an html table? My data contains about 10 rows and 20 columns in the spreadsheet. I’ve been looking into using associative arrays or nested tables but I’m getting confused about how to implement them in my situation.
    Any help is greatly appreciated.

    BluShadow,
    Thanks for your response. The reason that it is a blob is that we use the same table for uploaded files for several applications. Some files are text, some excel, some other formats. Hence the table has been set up in a generic sense.
    However, in my procedure, I'm using
    DBMS_LOB.createtemporary and
    DBMS_LOB.converttoclob
    Is there any way you could possibly provide an example of how to read the contents of the file?

  • Reading in a binary file and displaying an array correctly

    I am teaching myself Labview 7.1 and what I am trying to do is read in a text file of binary digits 10011001, 11011101 etc and then output these to a series of leds (boolean array) as well as to another array to display what was read in. I can get this to happen when I format the text file as 1,0,0,1,1,0,0,1 but then the array is 1 column by 8 rows (is this a 1by8 array) I want to read this data in as 10011001 displayed on 1 row and then the next row of the array to be 11011101, it displays 11111111 if I go above 3 digits, I know this is just a problem with binary versus decimal numbers, how can I format the input file so it is read in as 8-bit binary?
    Thank you in advance,
    Dan Ziehm

    Read the text file as string, then pass it through "spreadsheet string to array" with "," as delimiter, %b as format and an U8 array as type. I made a quick demo, see attached code image.

    import java.io.IOException;
    FileReader f =  new FileReader("c:
    FileName.ext");
    while ((s = in.readLine()) != null)

    You cannot append columns to an existing file. Since the data is arrange line-by-line as one long linear string in the file, you can only append rows. A new row needs to be interlaced into the original file, shifting everything else. If you want to append rows, you need to build the entire output structure in memory and then write all at once.
    (I also don't think you need to set the file positions, it will be remembered from the last write operation.)
    Unless the files are gigantic, here's what I would do:
    (Also note that some of your rows have an extra tab at the end. If this is normal, you need a little bit more code to strop out empty columns. I include cleaned up files in the attachment. I also would not call them A.txt.txt etc. A plain A.txt is probably sufficient.)
