re animation with xputimage hi i m new to this group so please bear with me two years ago i wrote a sunview application for fast animation of raster files with sunview becoming rapidly obselete i ve finally decided to rewrite everything from scratch in xview i put together a quick test and i ve found that xputimage is considerably slower factor of on average than the sunview command pw rop which moves image data from memory pixrects to a canvas this was on a sparc ipx it seems that the x protocol communication is slowing things down or xputimage is inefficient or both my question is what is the fastest way in x r to dump plane image data to a window can i take advantage of the fact that the client is running on the same machine as the server or am i stuck with xputimage in which case i might as well give up now all help appreciated thanks derek in article infodev cam ac uk dcr mail ast cam ac uk derek c richardson writes derek c richardson tel x institute of astronomy fax cambridge u k cb ha e mail dcr mail ast cam ac uk animation is most frequently done by copying the the client resident ximages into server resident pixmap s using xputimage once this is done the original ximages can be deleted and the animation loop can be performed using xcopyarea from the pixmaps to the windows drawable hope this is helpfull john
