1665.0. "SETTING/GETTING PIXEL COLORS????" by SPI1::DWORKIN (David Dworkin --LMO4-2/C2 DTN 296-5657) Fri Nov 03 1989 09:42

    I'm writing an application where I need to be able to do two things:
    
      1) Give an x,y location and a color (maybe a 3-tuple), and set the
         pixel at that x,y to the specified color
    
      2) Give an x,y location and get back the color of the pixel at that
         location.
    
    Does anyone know of an easy way of doing this?
    (Please send me mail if you can, PIPA::DDWORKIN or SPI0::DWORKIN)
    
    thanks,

	Look in chapter 10 in Scheiffler, Gettys and Newman, _X_Window_System_ there you will find information on XCreateImage, XGetPixel, XPutPixel. You should also look in 6.7 for discussion of XGetImage and XPutImage. Dick
