description: As I understand MOVIE tv's an image directely to the window; an indirect way however would be faster: - first open p.e. 20 windows with keyword /PIXMAP - display 20 images into the (pixmap)-windows - open a display-window - copy the images to the display window via DEVICE, COPY=[...] Karl ____________________________________________________________ __________________ __ ____ __ / // _ \ / / Karlheinz Knipp phone: +49 511 - 762 4922 / // /_/ // / University of Hannover fax: +49 511 - 762 2483 / // ____// / Institute for Photogrammetry / // / / / Nienburger Str.1 /_//_/ /_/ FRG 30167 Hannover 1 email: knipp@ipi.uni-hannover.de

The problem is not hardware, but implementation of MOVIE. MOVIE does repeated TVs to cycle thru the images. This requires the client (PV-WAVE) to send the image data to your X server over and over again. XANIMATE opens a large pixmap window, and TVs all of the images there once. It then sends repeated DEVICE,COPY=... commands to let the X server handle the image copying. Bottom line - much faster. -- Dave
