Converting Multiple Page Tiff Files

[jmassey]

I am trying to convert multiple page color tiff files to multiple page black and white tiff files.

I would use monochrome to do the job, but some of the pages have a red background and thus appear all black.

When I try to use -threshold 35, the pages are all white. The code I used is below:

Code: Select all

convert color.tif -threshold 35 bw.tif

When I use the same -threshold 35 on single page tiff files with the same image, it comes out correctly.

Any help would be greatly appreciated. Thanks!

Nevermind. I forgot to include the % after the 35. Sorry.
