get the specific channel pixels

Hello world!

Nobody knows
How to get to the Pixel values of each channel separately? I want to transform RBG to XYZ and I change channel od pixels. Pleasse help!

A filter could simply use AdvanceState calls as usual.

And if you want to convert RGB to XYZ, you need all 3 channels at the same time, not separately.

  • Get the specification of the full path of the file to Flash and QuickTime icons animation?

    How to get the specification of the full path of the file to Flash and QuickTime icons animation? I want the path and the file name contained in these icons. I use a "diving" to browse the icons to a file, and when I come on these two types of icons, I want to get the information above contained in them. I can certainly look in the Properties dialog box for this info, but there are a lot of icons in these files, and I want to generate a list of information based on different types of icons that I'm processing. Thank you

    Steve,

    When I tried GetIconProperty (IconID, #filename) as part of my 'dive', it worked when he met the QT icon. That is what I wanted.

    Not sure why it doesn't work with my small test case that has been a calc icon that followed a Falsh or QT icon.

    Thanks again for your quick response with the correct solution.

  • get the dimensions in pixels of office?

    How can I query the findout the dimensions of the screen desktop system, the program runs on?

    I need to popup a window full-screen without borders, up to now, I had control of the hardware, so I know that the resolution of the screen (1920 x 1200), but there is interest in a system of "just an application" so I have to deal appropriately with different (probably smaller) resolutions pixels maximum.

    This window is basically a canvas tile controls programmatically created the only real question is so get the size of the screen running and creating tiles or print a message of error if the screen is too small for use (i.e. 800 x 600)

    int i, [9] w = {0}, [9] h = {0}, Nmonitors, monitor first, primary, [10] = {0}, albums [9] = {0}, left [9] = {0};

    GetSystemAttribute (ATTR_NUM_MONITORS & Nmonitors);
    GetSystemAttribute (ATTR_PRIMARY_MONITOR, & primary);

    Thanks, the code snippet above seems to have all the info that I need to use only the CVI calls.  I usually mix CVI and Win32 call anyway, but this avoids having to dig up the documentation on the Win32 structure typedefs.

    Thanks for the links to the Win32 multi-monitor documentation.

  • How to get the physical channel for USB card as ENET

    Hello

    For my application (VB .NET, using NIDAQmx 8.8), I need to access the 2 cards:

    a USB-6008 and an ENET9163.

    I would like to read the physical channels automatically with this feature NI-DAQmx

    Physicalchannel1ComboBox.items.AddRange (DaqSystem.Local.GetPhysicalChannels (PhysicalChannelTypes.AI, PhysicalChannelAccess.External))

    Unfortunately, he didn't get a single card at once.

    When the USB card is connected, he read the physical channels of the USB card

    When the USB adapter is not plugged in, it read the physical channels of the ENET card.

    I hope someone can help me with this problem!

    Thank you

    RB

    Hello RB.

    To read from multiple channels, you can enter in the drop-down list box "Physical channel", the comma separated channels, custom channels or if you read physics, the string "DevX/Benjamin: Z", where X is the number of device, and X and are the first and the last channel you want to analyze (for example to read to ai0 to ai4 from your device 1 enter "Dev1 / ai0:4"). Among the names of your channels, I guess they are global channels created in MAX? You can always read channels multiple and different advice by separating the comma.

    I hope this helps!

    Kind regards

  • Impossible to get the specific features of cisco in LMS syslogs

    Hello

    It's about a problem that we face with our LMS 3.2.1. We cannot get specific cisco devices syslogs, while we are able to get the rest devices syslogs. one you suggest what would be the exact reason for this and the troubleshooting steps.

    Thanks in advance,

    Raja

    Hello

    The first thing I would say is to make sure that you have these devices configured to send the syslogs to that specific server. See config below:

    3725B - CR - NMS (config) #logging host?
    Host name or A.B.C.D IP address of the syslog server

    If that is already set up, please make sure that syslog messages are on the server. Create a message simple syslog and check the syslog.log file located in NMSROOT/CSCOpx/log to make sure it's written there. You can also run a capture of packages to confirm the foregoing. If you have this installed on Linux/Solaris, check the syslog_info file (/ var/log /).

    You can generate a test syslog as shown below:

    3725 B-CR-NEM #conf t
    Enter configuration commands, one per line.  End with CNTL/Z.
    3725B - CR - NMS (config) #exit
    B-CR-NMS 3725 #.
    * 03:35:42.613 13 Oct: % SYS-5-CONFIG_I: configured from console by admin on vty1 (192.168.10.197)

    NMSROOT is the LMS installation directory

    Let me know the results.

    Allen has.

  • How can I find (or at least get the specifications of) Dreamweaver CS6 layouts in Dreamweaver cc?

    Hello!

    I am a student of a course in web design, and many of our missions require that I use liquid layouts of Dreamweaver CS6. The problem is that I have Dreamweaver CC (who cut a large number of templates), and buy the old version for this class seems silly.

    Anyone know where I can find the standard CS6 layouts set to download? If not, anyone know where I could find at least plug on these layouts? I'm proficient in coding and web scripts, but I will not be anchored class points because I put a width of 75% instead of 80% or used an incompatible class name.

    Thank you very much for your help!

    If you have PCOC, you can also install free DWCS6 as part of your subscription to the CC...

    http://helpx.Adobe.com/creative-cloud/kb/download-previous-versions-creative-applications. HTML

    FWIW, CBWMS removes these old patterns because they were considered outdated or redundant (because they were just variations of a basic layout) HTML standards.

    You can download DWCS6 and have access to all of them, open one, save it in your site and switch back to CBWMS if you wish.

    As far as I know, they cannot be added to CBWMS, but you get the two programs as a CC subscriber, only, they do not work at the same time.

    Perfectly updated Firefox and Shockwave flash. Weather Channel videos cause a black screen with no option, but all the other sites I've tried seem to work well.

    Just for everyone's information...

  • How to get the numeric values with SCPI on an AG7034B

    Hello

    I use an Agilent 7034 osciloscope with 4 analog and 16 digital channels.

    Read analog channels is no problem, but how do I get the digital channels (101010) waveform?

    I see the digital signal on the screen of the instrument.

    And: I want to do with SCPI commands and read/write Visa.

    Thanks for all tips

    Do you really mean the DSO7034B? If so, there are drivers available for LabVIEW and other programming environments. I suggest you only start with one of these. Check your manual to become familiar with the controls.
