I am building a display window for live sonar data and wan't to create a scrolling display with the sonar data moving upwards as I paint new data on the bottom of the window. I am currently using XCopyArea to perform the scroll and XPutImage to draw a new line of 8 bit grayscale data on the bottom of the window. Is there a faster way to do this ????

Take a look at the source code for XDataSlice (to be found via anonymous FTP on 128.174.20.50/zaphod.ncsa.uiuc.edu); they set up no less than 15 scrollable pixmaps in one window as part of the 'unfold' feature for 3D datasets. I don't know how... but it might be worth a look. Marc
