Much better. I like the look better, but (putting on my graphics-guy hat) that GIF is *huge*. 175K is a tad of an excessive download for a web-page frammish. Also it doesn't look very good if your browser's page background is not white --- there's a white ring around each continent thanks to poor antialiasing. The extent of the dithering makes me think the image was made from a truecolor original. If so JPEG at a moderately high quality setting would work better (and look much better on truecolor displays), though you'd lose the ability to have a transparent background. PNG is also a possibility if you want to assume that visitors have recent browsers. regards, tom lane organizer, Independent JPEG Group member, PNG development group

It started at 24K, a load/save in xv brings it back to 24K. Let me look at that. Seems to have grown somehow. It is the transparency that is causing it. I am using 'convert' to add the transparency. Have other people seen 'transparancy' increasing the file size? -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

See Magick.tmpl or Makefile.in. I am running 3.8.9. Oh, well, have to wait for a BSD/OS upgrade, or do it myself. Actually, changelog for 3.7.* say: Rather than a separate LZW kit, Image Magic now comes as two distributions. One with LZW compression and one without (suggested by pederl@norway.hp.com). -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
