  • MS-Windows: take a picture from the webcam

    Dear Tcl/Tk developpers,

    I have a MS-Windows Tablet with 2 cameras (front/back).
    I want to read a QR-code using the cameras.
    And the user should be guided by a picture while scanning.

    What I need from Tk:
    - select a camera
    - take a picture (tk image ?)
    - show it to the user (Tk label with an image ?) (probably scaled down)
    - start the barcode decoder and get the information bc/no bc
    - if no bc, get the next picture
    - abort by an abort button

    Does anybody has an idea for Tk for this ?

    Thank you for any answer,
    Harald

    The closest architecture I know for that, and based on Tk is AuDela https://sourceforge.net/projects/audela/

    It is not very active but alive.
    You could take picture from a telescope through a camera.
    One difficulty is that it is based on BLT which with its tabnotebook
    and image processing should answer to some of your needs.
    But refactoring BLT no more have those functionalities I think.
    The maintener has made some changes so you could contact him ?

    Best regards,

    Olivier.

    Dear Oliver,
    thanks for the great pointer.
    The work by magic-Mr-Androwish perfectly suites me.
    I made it work with MS-VS2015 and Chritian integrated the patches !

    Thanks for all,
    Harald
