Yeah, I just tried 300, 600, 1200, 2400dpi while setting cost factor to 66.
Higher DPI value indeed results better PDF quality. But I still prefer cost
factor 65, because
1. Size matters. With same dpi value, cost factor 65 results in a much
smaller PDF file. Examples:
- 66-2400dpi.pdf is 15523 bytes
- 65-2400dpi.pdf is 8386 bytes
2. Name matters. Processing a hello.c file into a PDF,
- With cost factor 65, it give me a hello.pdf
- With cost factor 66, it always give me a _stdin_.pdf. So I have to
rename it to something else before it's overwritten by next run.
