If I scaled using linear interpolation, the letters were blurry at higher magnifications. If I scaled using cubic or Lanczos interpolation, it caused some disturbing artifacts, especially at higher magnifications within the .pdf file. Anyone know of a way I can use a full sized 8.5x11 graphic without it taking over a megabyte of memory? One would think it would be very compressible. Over half the graphic is contiguous pure white, with another 10% contiguous pure black. I figured it out. With a really big graphic, you you must create the graphic as a .eps, and within LyX include that .eps. Whatever graphic conversion programs LyX uses blows converts from .jpg or .png to a HUGE .eps, much bigger than the .eps would be if you created it directly from Gimp.

Steve, Probably the best way of getting a full page graphic with a reasonable file size is to use a vector graphic. I haven't used them for covers, but I have used them for full page illustrations within a document. Some vector graphic formats can be taken care of automatically with Lyx -- Grace .agr format, for example, which I use very often -- while others you might export as a .eps file from the application that generates the graphic. -- Les ~~ Please avoid sending me Word or PowerPoint attachments.

But if you still want to use a bitmap format, old plain GIF seems to be the solution for this case. Just index your figure with as few colors as possible. For this kind of situations GIF does a way better job than JPG.
