extract a part of a picture to manipulate

I tried to extract a part of a picture so that I can work on only a part of it.

First of all, I import an image and use the tools KING to get the global rectangle.  Then I try to use the global rectangle to extract the part of the image that I want to work on.  That seems to work, except when I move the Courvite back on the original image, the original image "becomes" the extracted image... I tried to copy the original image before working, but the same thing seems to happen... any thoughts.

This is because you have connected your destination "img" imaq extract.vi to a new imaq create. Create one, give it a different name. It will work.

  • Can someone tell me how to extract a part of a digital waveform?

    I am trying to extract a part of 2 analog waves (using the http://zone.ni.com/devzone/cda/epd/p/id/4149 for example) analog signals is synchronized with a digital waveform.  I need to extract the same portion of a digital waveform.  Can someone tell me how to add the digital extractor in the example above?

    Hello

    Here's your extractor example slightly modified in order to add the digital data extraction.

    The principle is exactly the same, the tricky part is how to get digital data which is different from analog data.

    You can also add nodes property to identify the value read on the analog graph sliders on the digital chart.

    Kind regards

  • How can I extract a part of a signal inside a loop control and simulation?

    I would like to extract the part of my signal between 0 and 3 seconds. I tried to use the extract of Portion of Signal VI Express, but it does not work. I'm setting the length to the offset 0 and 3 seconds. However, nothing is displayed in the output. I used this before VI successfully, but it wasn't in a loop control and simulation. Is there something special I need to do to make this work properly in this case?

    Just add your photo on a higher video track, it will cover up to a below. You can use the effects of movement to move and scale the image.

  • Some parts of my picture appear as black boxes?

    When I open a photo after editing the raw photo and try to make other parts of the photo montage are blackened with various sizes of rectangles and rectangles in other places changes when you zoom in and zoom out on the picture, anyone know what could be the cause and how to stop?  For example, I would need to zoom in before to make a great edition on the eyes, but when I Zoom, the whole head could be locked out and I don't see the part of the picture.

    Some notes on this:

    Go to the preferences of Adobe Camera Raw 9.0 and down, uncheck "Use graphics processor."

    Watch the latest posts here: Re: Photoshop suddenly began to place an ontop big black box of the image - its only present on the screen if I save the image is gone - the box (sometimes white black sometimes) obscures what Im doing

    and you can see that ACR 9.0 update is causing this problem for some.

  • Best way to get a part of a picture

    Hi, I m doing a behavior with bitmaps but a little confused.

    Objective:

    (As shown in the attached picture)

    I have a Movieclip with a static form on stage (Let´s for example... a star)

    I would like to load an image (img1), then I would be able, rotation, zooming and panning of the image (img1).

    Then I would only have the star but filled with the part of the image that has mounted this star.

    I was trying to get the image bitmapData, then draw the star on the image... And in the end, compare the pixels of color and only get the ones I want... but I get a big mess with rotations, scaling, and the positions of the stars to exactly the place we need to draw the being...

    Something tell´s me this I m missing a point and it would be easier...

    Can someone give me sense?

    It s a kind of mask, but I want to save this picture so only...

    Thanks in advance!

    extractStar.png

    I'd do it:

    (1) go and translate your image clip

    (2) adjust the star under the mask

    (3) once the mask applied, use BitmapData.draw to draw the image hidden in a new data bitmap

    (4) TADA!

    As far as I know, 'draw' should respect the masks? If not then you need to clip + mask inside an another DisplayObject and attract.  Some pseudo code (not tested and simplified):

    // Parent object
    var canvas : Sprite = new Sprite();
    canvas.addChild( clip );
    canvas.addChild( star );
    
    // Manipulate your image
    clip.rotation = 35;
    clip.scaleX = clip.scaleY = 1.2;
    
    // Set mask and position it
    clip.mask = star;
    star.x = 40;
    star.y = 20;
    
    // Create a bitmap data and draw to it
    bitmapData = new BitmapData( Math.ceil(canvas.width), Math.ceil(canvas.height), true, 0x00000000 );
    bitmapData.draw( canvas, ...... );
    
    // You may need to use canvas.getBounds and create a matrix to get 'canvas' positioned correctly on the bitmapData
    

    It will be useful,

  • Extract a part of a large MP4 in a swf

    I would like to create a swf (about 2 minutes) from a file (12 minutes) larger MP4. I can do using other software, such as Roxio Videowave, to extract the desired part and create a new shorter than Flash Pro MP4 can handle. My question is whether it is possible or even practical, to make video extraction using just Flash Pro. It would be desirable to do so because the step of additional software seems to reduce the quality of output.

  • Extract a part of SelectedItem.data of ComboBox

    Hello!

    I only use AS2.

    A ComboBox is filled with elements all built on the same pattern:

    Each element contains:

    1 - name of the location (which can contain hyphens, spaces and apostrophes)

    2 - details (always indicated in parentheses)

    The user selects an item that will be sent to research purposes via PHP to query a MySQL database.

    The variable to send should only be the name of the place , because the location of my MySQL Table column contains the names of place without details.

    How can I extract only the name of the place?

    Thank you very much in advance for your help!

    Best regards.

    You can use...

    dataToSend = String (yourCBName.selectedItem.data) .split ("(") [0]; ")

    where 'yourCBName' is replaced by any name you assign to the combobox

    This line will split the data line in two parts where begins the parentheses and point to the first part of it.

    We know not if you use the appearance selectedItem.label of the combobox, that could help.  What you might consider doing is to have just the data part of the combobox control have the data you want to send, and use of the part of the label to display the entire bit of text you show... or the reverse of the where the label is just the part of name and that is what you send.

  • What would be the best way to change the color of a part of this picture? (image attached)

    I am on XP using PS CS4.

    Please see the picture below. I would like to change the color of the shirt/deck of this lady, and I was wondering what the best way is to do it. I know that if I try to change the color, white bowls change color as well. In the past, I've isolated parts of images using paths, but I wanted to know if it was the most effective way. Maybe the masking is the answer. I just wanted to hear from the pros

    Untitled-4.jpg

    Thank you.

    I'm not pro, but you can isolate areas likely to be affected by the change of color. Try the quick selection tool (which detects the edges) with mask edge/refine refine to refine the selection.

  • By selecting the part of a picture in paint

    When I open a picture in Paint in Windows 7, there is a small white square "handles", bottom, right and the lower right corner. I can use these to crop the picture from the bottom and right sides, but there is no squares at the top and to the left for some reason any. Why are these squares on the top and left sides? What is the point of them only being down and to the right? If photos open in paint with these grips on all sides and corners, it would make cropping extremely simple, since you have not all first select an area, you just move the margins to where you want the border of the picture to be.

    So if I want to crop from the top or left, I opened the with the rectangular selection tool select and draw a rectangle around the area I want to keep. This works very well for simple cropping where the location of the agricultural frontier of dotted line is not critical. The defined area that results from cutting is described with a line dotted with the same white square "handles" on the sides and the corners, but this time, they are on all sides and corners, as it should. The problem is, once you release the button of the mouse and the harvest dotted area is defined, you can not adjust the crop box by entering one of the white squares and dragging the dotted line without DISTORTING the content within the cropped area. Why would you do THAT? I thought that these handles were there, so you can just move the initial harvest defined by the tool border select.

    Does anyone know how to accurately adjust the selected area in a photo?

    I have to admit that I don't know the details of the use of paint, but you could download IrfanView, which is free, able to view a wide variety of image format files, converts between these formats of image files and cultures of the images in the way you describe how you think it should work.

    It is in IrfanView, you set the crop area by dragging on the area and can then adjust by moving the up, down, left or right (not the corners).  The image in the collection area does not distort.
