pdf to tif - result is fuzzy

Post by yarrow »

Hi,

I was converting a scanned pdf file(300dpi) to tif. The command I used is as follow:

nconvert -xall -out tiff -dpi 204x196 -c 5 -o output.tif input.pdf

But the result is not as good as a file I manually faxed at 204x196 dpi. It is fuzzy. I was wandering is there anyway that I can improve the result?

Thanks

The better way is to load in a higher resolution (300dpi), and resize it

Thanks. Another thing is that the "-c 5" option seemed not to be working. The result image is in jpeg compression, not CCITT G3. I also tried "-binary dither" option, but it gave me "Bad binary dithering 'dither'".

Choose dither type from list. Ex: -binary floyd
