Change size of post-script file

Sefyir · 08-16-2016, 10:50 PM

I'm trying to double the size of the output of sudoku (program)
You can get one yourself to try (also put in code at bottom)

Code:

sudo apt-get install sudoku
sudoku -fpostscript -c"hard" > board_1

The problem is the output board is very small!
I'm trying to double the size but my results are blurry when converted to pdf.
My goal is to print them out in a easier-to-read size.

Code:

convert board_1 -scale 200% board_1.pdf

I think I'm going around this the wrong way since it's just a postscript file - I should be able to change the size any amount without any blurriness.

Code:

Hi

Making PDF files with ImageMagick is not so good. It will change it to bitmap. It's better to use epstopdf which keep it as vector graphics.

Code:

sudo apt-get install sudoku texlive-font-utils
sudoku -g -fpostscript -c"hard" | epstopdf --filter >board_1.pdf
