QUOTE (jamescanvin @ Jul 1 2008, 11:19 AM)  However for really big images like full resolution 360 degree pans the GIMP really struggles and I then use Photoshop which can handle these much better. I was trying to manipulate some large images (planet texture maps 21k pixels wide) & the ImageMagick library on a RAM-challenged old Linux box was just crashing. There's a JPEG2000 format or something which is supposed to facilitate handling large images at differing crops and resolution, but I haven't looked into that. A simple (although slow) stopgap was to create a much bigger swap file so there was enough virtual memory, & it eventually chugs through (in that case splitting the big file up into tiles). -------------------- |

Thank you very much for your answers James. Very much appreciated. I must try & few more things myself. I will be keeping an eye out for further interesting images.

Do they plan to send back a panorama composed of lossless images like they did with Pathfinder later in that mission?

There is a plan is to conduct a lower compression, more filters, less down-sampling pan as I understand it ( called the Re-Peter Pan ) Of course, with Pathfinder, it had 1/16th the resolution to contend with.

Hi Doug,
That is going to take some time & a huge number of frames. Is there enough time left in the Primary Mission to accomplish that? What would be interesting would be a horizon pan at around the time of the Midnight Sun, do determine atmospheric light scattering, etc. Andrew Brown. -------------------- "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

A crude attempt at filling in the deck and panels using the ground-based test images.
The real thing should be spectacular!

Great job Astro - I'm still working on getting the deck pan added to The Peter Pan
Doug - Maybe I'm wrong but I thought the name Re-Peter Pan was just applied to the the repeated bits of Peter Pan where there were dropouts in the data the first time around. Andrew - yes it will take quite a long time - it depends just how much compression and how many filters are used - but I could imagine the horizon pan being done by the end of the primary mission. -------------------- |

The full colour version is going to be tricky to pull off I think, however in the meantime here is a quick greyscale version. 144 images in this!
 Polar version  Click image - quarter of full resolution James -------------------- |

Well... As long as you eventually get the colored version completed, James...before the end of next week. J/k
 Good work on those greyscale images -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

BBC's The Sky at Night did a great job - sent Chris Lintott out to Tuscon for a day or two and had a brilliant half hour program on BBC4 just now.
I noticed something in the background of an interview....
Notice anything cool? A nice big print out of an early chunk of the Peter Pan in there. But it's not the NASA version - http://www.nasa.gov/mission_pages/phoenix/...AAM2_newer.html - see, no black borders. It's this one - http://www.nivnac.co.uk/mer/index.php/2008...1bc-6-pointings It's JC's mosaic on the wall at PHX HQ. Like an art insurance specialist - it's all about the border A flick comparison for added 'Bloody hell, you're right'There you go James - that's twice you've been on the Sky at Night now
