Tested in Ubuntu 19.10, ImageMagick 6.9.10. Usage questions are like 'How do I use ImageMagick to create drop shadows'. If not, use the Levels or Curves tools to adjust the white background, black ink and gray edges as desired. The -fuzz option allows the specified percentage deviation from the pure white colour to be converted to transparent as well. This makes all the greyish text pitch black plus makes the text sharper and turns most of the whitish pixels pure white. Then use this command: convert image1.png -fuzz 20 -transparent white result.png. ![]() ![]()
