jit.desktop full resolution capture then resize ?


    Feb 02 2011 | 5:19 pm
    Hi, I am more or less completely new to the whole world of Max MSP and jitter, however i have been trying to teach myself the basics over the last couple of weeks.
    I would like to capture my whole desktop using the jit.desktop function, i manage to get this working correctly with no trouble at all.
    My question is can i then take this full desktop resolution and scale that down to a specified size (the same way you can with the jit.qt.movie) ?
    I have included the patch i have so far, the project aim is to be able to display quicktime movies and a desktop capture over serial over usb to an arduino, which in turn will pass SPI data to a matrix of 16 Sparkfun RGB matrices - resulting in basically a 32x32 pixel low resolution version of my complete desktop capture.
    any help and advice on this scenario would greatly be appreciated.
    Many Thanks
    Jack

      you can specify a resolution lower than the size of the capture rect. like this: jit.desktop 4 char 8 8 @rect 0 0 320 240
      which captures 320x240 pixels from the desktop, and downsamples to 8x8 pixels before outputing the matrix.
