The original Topo50 TIFFs include legends, borders, etc. Presumably, the OP wants to cut the borders, create a single large image for the whole region, then divide it up into suitable pieces for printing on an A3 or A4 printer. You say you used Image Magick to combine the TIFFs. Why not use Image Magick to divide it up again? If your computer can contain the whole combined image in Image Magick, then ImageMagick has the wherewithal to output different parts of the image into separate files. You then have the problem of making the bits print out at the correct size (300 ppi). Use the -density command line option to set the resolution in dots per inch. Many image viewing programs will honour this value and give you the option of printing at the specified resolution. Except for Acrobat Reader, I do not know of a PDF or PS viewer that lets you specify the size to print. They all seem to scale to fit the entire sheet. Stephen Irons
