I'm using tiff-v3.4beta035 and I've got some 22x17 inch tiff files that I'm trying to 11x8.5 inch pdf files. I'm using tiff2ps to create PostScript files, and then am using Adobe's distiller to create the pdf file. If I do:

tiff2ps file.tiff | distill -compatlevel 3.0 -resolution 300 > file.pdf

I get page size of 22x17 inches and the image occupies the whole page.

If I do:

tiff2ps -h 8.5 -w 11 file.tiff | distill -compatlevel 3.0 -resolution 300 >
file.pdf

I get a page size of 22x17 inches and the file occupies 1/4 of the page (11x8.5 inches) with acroreader.

Any ideas how I can make the page size 11x8.5 and have the image occupy the whole page?

I can send you the tiff, ps, or pdf files if you'd like to see them.

The reason for your problem is, I think, that tiff2ps outputs an EPS file, i. e. a device independent PostScript image which has to be properly embedded into a PostScript job.

If you have a look at the EPS file produced, you'll see a comment line like

%%BoundingBox 0 0 1584 1224

which is the smallest rectangle enclosing all elements of the image. If your page size is 11x8.5 inches, i. e. - in PostScript units - the box 0 0 792 612, you should prepend something like the following to the tff2ps output:

%!PS-Adobe
<</PageSize [792 612]>>setpagedevice % define the size of phys. page
0 0 translate % put the image origin onto the lower left corner
1585 0 sub 792 0 sub div 1224 0 sub 612 0 sub div % scale the image down
% include the image here

For detailed information, refer to Adobe's "red book", 2nd edition, App. H, Encapsulated PostScript File Format.

I think this mini header will settle your problem.

By the way, do you have a distiller for UNIX? If so, where can I get one?
