is mr. nomaintainer informed? :-) and it would be really great, if the PNG patch could really be included: missing PNG support is the one big shortcoming of `xv'. as `xv' seems otherwise frozen since the mid nineties applying the patch seems a one time action. and for standard tasks `xv' still seems really superior to `ImageMagick' (standard operations such as edge detection run faster by a signifcant factor (5-10) and yield really much better results). joerg _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo/macports-users
