  • How to use IMAQ detected Shapes.vi

    Hi all

    I learn NI Vision, I don't understand how to use IMAQ detected Shapes.vi to detect shapes, such as lines, ellipses, who can give me an example, thank you.

    Hello

    This function uses the edges of the object and try to adapt with different shapes such as rectangles, lines, or some cirles.

    First of all, you need to set parameters to extract the edges of your objects. You Brown the threshold (in order to find the correct edges of your object). You can then choose the parameters of the shape to fit. For example if you want to adjust with a circle, you set the min and max possible RADIUS.

    Try this with vision assistant, it will be easier. And try also with fine contrasting images.

    Basically what you do is place the playhead of the ICT program at the beginning of your clip, open the effect in Control Panel effects applied and set the Position of the brush (which will be represented by a small dot with reticle above) to place on your video, you want your animation to start. Then click on the stopwatch the top effects applied to open the workspace control key-frame and click on the timer to the right of the list Write-On icon to start the animation. (Initial keyframes will appear on the timeline of keyframe control).

    Move the playback cursor and change the Position of the brush. A new image will be created and your dot will become a line. Place the head again and change the Position of the brush again. Continue to move the playhead and change the Position of the brush to build your animated line.

  • Save to PNG using IMAQ file write file does not save good Gray Scale

    Hi - I have a simple VI which reads a raw U16 file and then try to save the option IMAQ write PNG file (because I want the 16-bit format).

    I defined a custom color table which is just opposite of gray, and this is applied to the image.

    The Image displays properly, but saves the PNG file with non-inverted grayscale.

    U16 RAW file is titled "Martha 1849-02-001-6 - view0000_raw_grey_16bit.raw' and sent to ftp://ftp.ni.com/incoming. "

    How is it and how do we get this working correctly?

    Thank you

    No! your custom color table to display the images, not apply to the image.

    In additional, it cannot save the palette as well as the 16-bit image. The pallet can be stored with 8-bit 'indexed' image.

    What you can do - if you need just reverse gray, use IMAQ opposite to calculate the negative value of an image.

    What is microsoft xps document writer and xps Viewer and how to use it?

    Hi arunin,.

    An XPS document is a file that is saved in the XML Paper Specification, or .xps, file format. You can create documents XPS (.xps files) by using any program that you can print from Windows; However, you can only view XPS documents by using an XPS Viewer, such as the one included in this version of Windows.

  • How to use Google Fonts in email?

    Hello

    I would like to know how I use the google font in my emails.

    We use ubuntu police and I see the fonts on my computer but after sending an email change fonts.

    I use the SmartTemplate4 addon.

    I hope that all f you know the answer!

    Thanks in advance

    It would be useful if you have linked the articles you found before you write. If I know you already read about it, I would have not spent time looking for you.

    The items I linked to are quite detailed. I doubt that this would trigger the SPAM detection, though - that's just my opinion of many years dealing with SPAM.

    Regarding your last question, well, only you know why you would need it in the first place. It took years for people (and the email clients) even consider using HTML, fonts are another component of this discussion (ie. content vs presentation/container). Personally, I don't receive e-mails with too much formatting.
