very nice! i modified resize to accept the same arguments as resample. it is blistering on my machine. unfortuntely, jpg still can't keep up. ; time jpg -t9 2246.jpg | time resize -bx 500 | page 1.96u 0.08s 2.20r jpg -t9 2246.jpg reading through graphics... 0.06u 0.04s 2.36r resize -bx 500 (a quick test shows that jpg has about the same performance with p9p and 50% of the ticks are in colormap:1420/62424) i have been using a script to use resample to convert pictures as i load them from the camera. to images the resample on a core i7 machine can just keep up with the new usb. (about 4mb/s. i believe this is limited by the spi-based media.) the resampled images can be displaed at >50/s. it's amazing how fast plan 9 video is when you don't read back from the frame buffer. :-) - erik
