Boundries returned when you view a raster map, in MapViewer are too large.

Hi all

I send a request to MapViewer and him asking to return a matrix card of one of my tables in the database. Whenever I have to do if I receive a wide blue border around the image, which I suppose is the background color.

This means that my extensions is entered in the SDO_GEOM_METADATA view for the table, are larger than the bodies of raster image? I would like the image returns to match my extensions of raster map. I've tested this with most raster image, I use so I know that no larger raster map is the origin of the problem. I work in MapViwer 10.1.2 using Oracle 10.2.
My XML code is as follows:
<?xml version="1.0" standalone="yes"?>
<map_request
 title="display test"
 datasource = "geg00001"
 srid="81989"
 width="679"
 height="510"
 format="PNG_STREAM">
 <themes>
  <theme name="georaster_theme" >
   <jdbc_georaster_query
   georaster_table="geg50160.web_raster_map_file"
   georaster_column="web_raster_map"
   jdbc_srid="81989"
   datasource="geg00001"
   asis="true">
   select A.web_raster_map
    from geg50160.web_raster_map_file A
    where web_raster_map_id=201
   </jdbc_georaster_query>
 </theme>
 </themes>
</map_request>
If anyone has any ideas, I would be grateful.

Kind regards

Tim

Hi Tim,.
the final map aspect ratio is defined by the application area and the peripheral zone. It is not based on the size of your original image. Indeed, when rendering a GeoRaster MapViewer Gets the highest level of the pyramid for the scale of the current map, and read the image data may be a less detailed representation of your image.
In order to not think about the relationship between your image size and the size of the unit. Think that the final plan is determined by the aspect between the requested data area and the peripheral zone ratio. You shouldn't be too concerned with the size of the unit, because if you zoom or zoom out changes in the relationship and the size of the map is adjusted to keep the appearance with the peripheral zone. For example, when you zoom in you will see your card covers your region of the whole device. You can play with your data in MapBuilder.

  • Events shown in the range of navigation when you view the properties of the system for recording of JFR

    Which record the events shown in the range of navigation when you view the Properties tab system for a Java flight recorder? I'm guessing that they mark the time for JFR's writing of the events on the disk.

    I ask because, during the capture of a lot of information with the help of JFR, we see two effects that correlate with these events: (1) CPU usage ramps up a little bit between an event and the back then, level departure after each event, even if the application workload is constant; (2) the clock used to time stamp on all the events THAT JFR capture high-resolution seems to run more slowly in the period following immediately each of these events, perhaps for the period while JFR is written to disk. The slowdown of the clock appears as an increase in the rate of events shown in the range of navigation in other tabs - I also analyzed the events selected out of the original EN file to check their apparent rate.

    I see this on Java EE applications running on JBoss EAP 6.x on Java 7 on machines virtual small vSphere.

    The events shown in the navigotor range in any time must appear at the same time they are created. not when they are written to disk which can be a little later, depending on the settings.

    In the System Properties tab, you generally see a single spike per segment in your record. You should see the same thing if you go to the tabgroup events and enable only the Java Virtual Machine system property / Initial if Types discovered.

    As for the damages of its use and CPU timestamp, it sounds interesting.

    What exact version of Java 7 you use, there would be some bug fixes in later versions.

    Sometimes when you view an Acrobat file created by others, square replace some characters.  How can I stop this?

    Hi John -.

    It seems that no one has answered your question. Sorry for the long wait!

    Squares can replace characters when you're dealing with missing fonts, or who are poorly integrated. It is important to see the text, you can ask the person creating the document to convert the PDF image pages PDF file, which then displays the fonts.

    Places instead of the characters may appear if you are using a scanned page, for example and capture the text.

  • Problem regarding content previously highlighted when you view the file in Acrobat DC.

    I have a problem with the content previously highlighted when you view the file in Acrobat DC. There is no problem in earlier versions of Acrobat. I pointed out the portions many documents with a point culminating opacity 50% and now shows the text in black and white and highlighted portions are not readable. This only became an issue when I recently installed Acrobat DC. The system is Windows 7. Y at - it a setting I need to select to make the text readable again?

    To change the color and opacity of the commentary on the matches of the current document, you can use script below.

    Note : this script will replace the opacity settings and the color of all the comments of highlight for PDF files open. Please save documents before store you settings to highlight comments. This script can be used until a fix is available.

    Steps to follow:

    1. open all PDFs in Acrobat DC comments are present in the games.

    2. press Ctrl + j

    3. in the lower part of the text, copy the Script below.

    4. Select all of the text copied in the previous step, and then press Ctrl + Enter

    5 opacity of all comment games goes to 100% and change color to light gray.

    *******************************************************

    var hightlightColor = color.ltGray;

    var highlightOpacity = 1.0;

    DDP = app.activeDocs;

    for (docNum = 0; docNum)< pdd.length;="">

    commentArray = DP [docNum] .getAnnots ();

    for (i = 0; i< commentarray.length;="">

    If (commentArray [i] .Guy == "Highlight": game commentArray [i] == "HighlightNote") {}

    commentArray [i] .opacity = highlightOpacity;

    commentArray [i] .strokeColor = hightlightColor;

    }

    }

    }

    **********************************************************

    You can change the opacity (highlightOpacity in above script ) for any value between 0.0 and 1.0, where 0.0 is transparent and 1.0 is opaque.

    Some possible values for the highlight color (hightlightColor in above script) are: color.blue, color.cyan, color.yellow, color.gray, color.magenta, color.red, color.green.

  • Sequence error recovery is returned when you perform a simple extraction

    Hi all

    According to my understanding, if extract us all lines of a sys_refcursor in a collection in the pl/sql block, then it returns no rows to the calling program. Instead an extraction out of sequence error is encountered. It worked well. However, when I use a single fetch statement (in which case the sys_refcursor contains a single line), I encounter no error "Fetch sequence. It would really help if someone could explain this behavior.

    Here is a sample code snippet that I ran into PL/SQL Developer:

    CREATE OR REPLACE PROCEDURE test_cur_1 (in_dept_id VARCHAR2,
    out_cursor OUT SYS_REFCURSOR) IS
    temp_count NUMBER;
    temp_rec dept % ROWTYPE;

    BEGIN
    -This piece of code is running in an error "Out of sequence", trying to open the sys_refcursor.
    OPEN FOR Out_cursor
    SELECT *.
    OF THE Department
    WHERE dept_id = in_dept_id ;--dept_id is the primary key

    LOOP
    EXIT WHEN out_cursor % NOTFOUND;
    EXTRACTION out_cursor
    IN temp_rec;
    dbms_output.put_line (' name of the Department: ' | temp_rec.dept_name);
    END LOOP;

    EXCEPTION
    WHILE OTHERS THEN
    OPEN FOR Out_cursor
    SELECT SQLCODE. » -> ' || SQLERRM FROM dual;
    END;
    ------------------------------------


    CREATE OR REPLACE PROCEDURE test_cur_2 (in_dept_id VARCHAR2,
    out_cursor OUT SYS_REFCURSOR) IS
    temp_count NUMBER;
    temp_rec dept % ROWTYPE;

    BEGIN
    -This piece of code does not run in an error of "search sequence". Instead the sys_refcursor exit opens for no line to display.
    OPEN FOR Out_cursor
    SELECT *.
    OF THE Department
    WHERE dept_id = in_dept_id ;--dept_id is the primary key

    EXTRACTION out_cursor
    IN temp_rec;

    dbms_output.put_line (' name of the Department: ' | temp_rec.dept_name);

    EXCEPTION
    WHILE OTHERS THEN
    OPEN FOR Out_cursor
    SELECT SQLCODE. » -> ' || SQLERRM FROM dual;
    END;


    Appreciate your time!

    When you browse a cursor Oracle doesn't know how many lines it will be in the cursor until he extracted all and it cannot know it has extracted all the until he makes a last checkout after obtaining the last row to find that it gets nothing in return. In the code of pseudo-device the fetch command works something like:

    open cursor
    cursor%notfound := null;
    -- This is the fetch phase
    ask sql engine to give me a row
    if I got one then
       cursor%notfound := false;
       populate variables/record with values
    else
       cursor%notfound := true;
    end if;
    -- end fetch phase
    go onto next command in the pl/sql block
    

    So in your first procedure you go get the last line of the cursor, then back to the top of the loop. Because Oracle knows not at this point that the last line has already been read so out_cursor % notfound is always false, so he sent for another how he now "knows" that the last line is read so notfound becomes true and your loop exits, returns control to the caller. At this point, no doubt, the appellant tries to retrieve the cursor. As the handle of the cursor already points past the last line, you get the extraction out of sequence.

    In your second procedure, check out you a single line of the cursor. You know that the cursor is oriented to the 'last' line since you query based on the PK, but Oracle is not yet known who. Now return you this slider to the caller who makes extraction more that moves the pointer beyond the end of the cursor. Calling it "sees" no lines, but it is because your procedure already recovered lines, but has not "checked" to the last line.
