Multipage PDF to TIFF conversion

Postby R2D2 » Wed May 12, 2004 9:46 pm

I succeeded in converting a multipage pdf file to a multipage tiff file with this command:
nconvert -o foo.tif -out tiff -xall -multi bar.pdf

The size of the original pdf file is approximatly 1MB, The size of the resulting tiff file turns out to be 42MB.

I'd like to decrease the size of the resulting tiff file. Color depth of the resulting tif file is 24bits. As the pdf contains a document similar to a fax (Black and White) I think a great deal can be done be decreasing the colordepth of the resulting tiff file.

I experimented a little with the -c arguments but resulting tiff file remained 42MB.

Any suggestions :?:

Try to use -grey 4 or -colors 4?
Is it possible to send me the file?
