How can I use GDAL to read pyramid georaster data?

I use this dataset = Gdal.openshared("geor:username/password@dbname,rdt,rid",Access.GA_ReadOnly method) to read raster data of georaster, but simply read data from the source. If I want to read the data of the pyramid of georaster, how could I do?

Kind regards

Lin

Lin, as Ivan explained in another thread, the cumulation is made by calling sdo_geor.generatePyramid, so the same block sizes apply on the pyramids. in your case, it would be 512 x 512.

When questioning a georaster object or its pyramids, gdal would still only blocks that overlap with your query window, the so-called selective recovery recover.

  • How can I change the attributes read-only or system files?

    How can I change the attributes read-only or system files?

    To view or to remove the read-only or system attributes, use the Attrib command at a command prompt:

    1. click the Start button, type cmd in the search box and press ENTER.

    2. to view the syntax for the Attrib command, Type attrib------? at the command prompt.

    WARNING: If you remove the read-only or a file system attribute, it may seem like a regular folder and some customizations may be lost. For example, Windows customizes the Fonts folder and provides a special folder view that allows you to hide variations, such as bold and italics. It also allows you to change the display settings of the file in a way that is specific to fonts. If you remove the read-only attributes and the Fonts folder system, these custom display settings not available. For folders that you have customized by using the tab, customize the folder properties dialog box, the folder icon and other other customizations may be lost when you remove the read-only attribute.

    If a program cannot save files to a folder with read-only, such as My Documents, change the read-only to the system attribute by using the Attrib command at a command prompt.

    To remove the read-only attribute and to set the system attribute, use the following command:

    attrib - r + s drive:------------.

    For example, to remove the read-only attribute and set the attribute to system for the C:\Test folder, use the following command: attrib - r + s c:\test

    Be aware that some programs may not work correctly with folders for which the read-only attribute and the system attribute are granted. You can use the following command to remove these attributes:

    attrib - r-s c:\test

    Please how can I use a value in a table of the adf in an actionListener to a button I created in a popup and thanks

    What is your version of JDev?

    Actually your question is not clear to me, but as I understand, it is you the table in the page and you have popup inside this popup you have the button you need when you click on the button to read the value of the selected table row. In the listener action button, so if you can get the current row of the table and after that you can get any attribute of the line as:

    DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("TableIteratorName"); // from pageDef.
    Row r = iter.getCurrentRow();
    Object value1 = r.getAttribute("attribute1");
    Object value2 = r.getAttribute("attribute2");

  • How can I use the sequence of the string "\u00e5" in myfile.txt converted unic

    How can I use the sequence of the string "\u00e5" in myfile.txt converted to unicode in my application?

    I have a text file, MyFile.txt, with some sequences represented unicode:
    \u00e5
    \u00e4
    \u00f6
    etc.

    This is the file contains unicode, not the character it represents: a, a and o.
    I get the sequence of the file and save it to a vector. When I tried to use it on a JButton, I see the "\u00e5" string and not the character that I assumed.

     
            read file codes ...
            ...
         Vector<String> glyphVector = readGlyphIndex.getUnicodeFiles();     // to retrieve the vector with unicode sequence and save it to glyphVector
         String unicode = glyphVector.get(0);     //get the first unicode sequence
            System.out.println(unicode);    //displays \u00e5 and not å in the console.
         jButton.setText(unicode);   //jButton is a JButton and it shows the string \00e5 and not the character å
            ...
    The question is how to convert the sequence of string to be a unicode escape in the code?

    In order to make it clear:
    //from
    jButton.setText("\\u00e5");
    //to
    jButton.setText("\u00e5");
    Thanks in advance!

    String s = Character.toString((char) unicodeInInt);
    

    Strictly speaking, if unicodeInInt is a Unicode code point (for example, it can be greater than 0xFFFF) then the correct code would be this:

    String s = new String(Character.toChars(unicodeInInt));
    

    However, since the "\u" notation allows only 4 hexadecimal digits (and need to 0xFFFF code points > Unicode represented by their UTF-16 encoding), the code above is not enough for this particular case.
