Hey Thomas, You are more than welcome! I hope you keep tinkering with the GIMP, it's one of the more cool toys I know of. And if you got paid for the job you asked about, you now have 'professional' experience. :o) Steve -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iQIcBAEBAgAGBQJRBNVDAAoJEDZ0Gg87KR0La7MP+wbttwCaKfQ4RsYYV4D5sVuz 0yy2kNtcO8HFdyV+FsyDQw/ZfuErxkdBln0cydSDfh8IDx5+LQ6nuwbbLRaoFsHD /krZEhpS7xIZvEXfzcGC/1xKC3vTVpVGOgUp0ZhFR8CjpXNXdLMeAu1yzFiec0wi If6jj/teo2RDJwZ4UEMAGUrWjQLQv6r31Tuux49fOzbwZj7G9IhnHFkblASeM+bN 50Umth1CrNeYMI0mZgLP9mC9mg5DHBKilaIuOAQ3tXVHvJZpPrc9FVDz6ZiXXGSL /Ai5MVUqo2GyseHFtvvN/zt3n3SDLO9vEtS+c9ik4N52MKHqX7gjNjwcx++UtfSY znReWLLpWL0feqKpmIS1XHK6gXHz0x0eLU4dDkl4tj831eQQP1QN2Dj6wYcgZRWf h4gYo/5xIEtyEu25lgBcf/vVGqghABcq2FmWQe1imB5rpaCA2IDSop3oEHJDoKFm TayW64myR3bEQkPtxUhJuxAdr/RpXTGn+0kMGgnU/yMp5QXR/LPy3H7N+enGy6Ce sjqbHO2CokQ2L1MX93ywbfNTUmyx0bXDni2y+dI7GnUHSHqtv6IRvHJjqPdAecuG 0hE57OxAf6yYWNzoXNjm5oy7ZIFuPETucRoXA4iV/Oij4d2PPX7J4WenUOoAR5up Gr/bzMhl4/W4/LJGHsol =KA9i -END PGP SIGNATURE- ___ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list
Re: [Gimp-user] help gray threshold
I got it done, Steve. It worked the first time. I used the Tools Color Tools Curves method with the value x=141 and y=64, the dot near the middle horizontally and 1/4 of the way up. The staff lines became considerably darker. Thank you very much. On 1/17/2013 8:39 PM, Steve Kinney wrote: On 01/17/2013 07:42 PM, Thomas Widlar wrote: 1.

But that means things can only get better - and better, and better. First thing is to open your PDF files in the GIMP. You did not mention a problem with this but if there is one, you might have to install and configure Ghostscript. If so, see: http://sourceforge.net/projects/ghostscript/ http://registry.gimp.org/node/25039 [for this purpose EPS = PDF] The Threshold tool, for converting grayscale (or other) images to 2-color black and white is at: Tools Color Tools Threshold Also of interest, a much more subtle tool is the Color Curves one, at Tools Color Tools Curves. Dragging the diagonal line down at a point 1/3 of the way in from its left end, and dragging it up 2/3 of the way from its left end, will make the contrast between dark and light regions much stronger - play with it to see what it can do. At the top of the Threshold and Curves windows you will see a drop box labeled Presets. This stores a history of past adjustments. When you find a setting that is just right, you can reload it by using this drop down list and selecting the one you want for e-z consistent results. And another thing to get used to: If you do File Save, the GIMP will save your file as an .XCF file, which is the GIMP's own native file format. To save as a PNG, JPG, etc., do File Export. In the dialog that comes up, you can choose the format to save your file in just by naming your file with the correct extension, i.e. example.png The GIMP will present the options for saving the file - i.e. compression / quality, embedded comment if any, etc. GIMP 2.8 is a fairly new release, and a lot of the newer features don't have help menu entries yet. On the other hand, you will find a lot of very useful tutorials on YouTube. And of course, if you are really stuck, you know where to ask.
