Draw a line on a CWImaqViewer durinq a continuos aCquisition

Can I Draw a line on a CWImaqViewer during a Continuos Acquisition. I Retrieve even the same error:"the object has been locked by an ongoing acquisition and may not be modified"

Hi,
I'm using NI-IMAQ 2.6.1, Vision 6.1 and a PCI-1407.
I ran the following example installed from the driver:
C:\Program Files\National Instruments\NI-IMAQ\Sample\VB\Grab
and everything worked fine, so I was able to draw lines during the acquisition.
Try with this example to debug your issue.

    Hello Valter Oliveira,
    Thanks for your answer. But I need some more detail about blank line text. i.e thrid point.
    Could you please tell me how to insert blank line text.
    1 - in your table, create a line type with only one column, with the same width of the table
    2 - in table painter, create a line under the line type
    3 - insert a blank line text in the footer section with the line type you have created.

  • Here are my last 3 duke dollars.  Can someone please help me draw a line?

    I have been BEATING my head on this for well over a week now. I'm new to Java2D and I cannot find even one example of this simple little thing that I am trying to do. Not one.
    All I want to do is draw an image, zoom that image, then draw some lines on that image, and then zoom it and have those lines show up where they should.
    For example, we have an image which has been zoomed. No lines are yet drawn on it.
    A line is added.
    The image is then zoomed in or out one more time.
    How do we get the line to remap to the newly zoomed image?
    What I am doing is:
    0) Load up an image from a file.
    1) Create a zoomed image by using the Image.getScaledInstance() method.
    2) Create a BufferedImage with the width and height of the image AFTER the zoom has taken place.
    3) Create a Graphics2D object by the createGraphics from this BufferedImage.
    4) Place the image into the BufferedImage by doing a BufferedImage.drawImage
    5) Select two points to be the start and end of the line.
    6) Draw the line using Graphics2D.drawLine(start.x, start.y, end.x, end.y).
    7) Zoom the image again (using the Image.getScaledInstance() method.
    8) Create a new ImageIcon using the image from above and override its paintIcon method like this:
    ImageIcon newIcon = new ImageIcon(newImage) {                       
    public void paintIcon(Component c, Graphics g, int x, int y)
    super.paintIcon(c, g, x, y);
    zoom(); //<---- ZOOM call
    Now in the zoom routine, what do I need to do to get the lines to draw at the proper location and size?
    Remember, the points of the lines (stored in a list as home grown line objects) are in screen coordinates, not image coordinates since they are just click points
    Note that when I use these points to draw a line, all is well (the line gets drawn where it should), but I have problems when I zoom the image.
    Thanks!

    Below is the documentation and method signature of
    Graphics.drawImage(Image img, int dx1, int dy1, int dx2, int dy2, int sx1, int sy1, int sx2, int sy2, ImageObserver observer);The important thing to note is that it does scaling on the fly if the size dictated by the source co-ordinates is defferent than the size dictated by the destination co-ordinates. The source image is always left un-touched.
    So basically your visual data is located in an offscreen image. You can draw a line on that. Then create a new image, get it's graphics and call drawImage(original_image, co-ordinates that cause it to scale how you like).
    Then you can draw lines on the 2nd image, create a 3rd, ...etc
         * Draws as much of the specified area of the specified image as is
         * currently available, scaling it on the fly to fit inside the
         * specified area of the destination drawable surface. Transparent pixels
         * do not affect whatever pixels are already there.
         * <p>
         * This method returns immediately in all cases, even if the
         * image area to be drawn has not yet been scaled, dithered, and converted
         * for the current output device.
         * If the current output representation is not yet complete then
         * <code>drawImage</code> returns <code>false</code>. As more of
         * the image becomes available, the process that draws the image notifies
         * the specified image observer.
         * <p>
         * This method always uses the unscaled version of the image
         * to render the scaled rectangle and performs the required
         * scaling on the fly. It does not use a cached, scaled version
         * of the image for this operation. Scaling of the image from source
         * to destination is performed such that the first coordinate
         * of the source rectangle is mapped to the first coordinate of
         * the destination rectangle, and the second source coordinate is
         * mapped to the second destination coordinate. The subimage is
         * scaled and flipped as needed to preserve those mappings.

         * @param       sy2 the <i>y</i> coordinate of the second corner of the

         * @param       observer object to be notified as more of the image is

    I have no idea what JTutor is, but if it tells you to override paint() in Swing, it's not worth its disk space.
    [http://java.sun.com/docs/books/tutorial/uiswing/painting/closer.html] clearly says that for all practical purposes paintComponent will be the only method that you will ever need to override.

    It's simple... I want the Illustrator pen tool to ALWAYS make corner annchor points and NEVER smooth.  Right now I have to convert every single one of them, or I have to do a work around every time I draw a line and make one of the handles disappear.  Is there some simple setting out there that will just "make it so?"@

    The video I am watching this guy is just dragging every line to make curves.  And every anchor point is a corner.  He is not switching back and forth between the pen and the anchor points tool, and he is not using the convert points tool.  He draws a curved line and starts another straight line only to curve it with a click and a drag.  It is super efficient, and I could save a world of time if I could figure out what he is doing.

  • How to draw a line on ADF page between two nodes  for mapping.

    Hi everyone,
    Does anyone have a solution that how can I wiring two points by drawing a line on ADF pages.
    My scenario is user want to do a mapping between two xml files. We will build an ADF faces page. This page have two parts, left part contains one tree(base on the source xml), right part is the destination tree(target xml). User can drag an node from left and drop to right. Meantime, a line will be created to connect two node, it would be perfect that when user scroll down the page, or extend the tree node, the line between source and target will be remain connection two node.
    Does anyone have a solution for this, thanks in advance.

    Hi,
    have you checked the two reports Matthias mentioned?
    After downloading the SAP Chart Designer the general procedure should look like: create your chart settings interactively using the designer. Save these settings as a local XML file. Use this XML in your ABAP application and additionally create a data XML at runtime (the format is described in the pdf of the SAP Chart Designer zip).
    Regards, Kai
    PS: Please don't use these very outdated function modules graph_matrix* / grstat* in new projects!

  • Drawing fading line

    Hello everyone!
    I am trying to draw a fading line on a desktop. For example: we have a JFrame instance on the screen, when we press right mouse button over the frame and drag the mouse across the screen, I want to draw a line, fading through time. I don't want to restrict the line in the JFrame bounds, instead I want to draw it on the desktop screen.
    Any tips or tricks. Thanks in advance.

    If you don't want to restrict the line to a single JFrame, I believe the JLayeredPane is for you. It allows you to have a transparent pane which overlays multiple Swing components.

  • Drawing preloader line with AS?

    Hello
    I have the following AS (2) in a preloader (which works - in
    the sense that it loads the next page):
    The preloader should have a coloured line which runs from
    left to right about 0.25px thick.
    Whenever I have tried to draw the line using a pencil, it
    appears too thick, or uneven, or even goes from right to left.
    I have noticed that if I occasionally delete efforts I do not
    like, even the next page fails to load.
    What I am asking here is if it would be possible to draw the
    line in AS?
    Thanks for any useful advice.

    Hello Devendran
    Many thanks for your post.
    So I would use something like:
    lineStyle( 1, 0xBDA0F2, 100 );
    moveTo( x1, y1 );
    lineTo( x2,y2 );
    But how would I incorporate that into my current Preloader AS
    (2)?
    Many thanks.
