prepare your Gimp images for the printing press.

The results are actually a lot like sgrafitto or other artistic scratching techniques, where you cover an image with thick oil paint or crayon and then scratch the con- tours with a of course, as many ways to use a Wacom tablet as there are artists, and most traditional drawing techniques apply just as well to the digitized ink pen and tablet as for real paper and ink pens.

GIMP is a complex program, but the development team has made strenuous efforts to flatten the learning curve for plugin writing: there are good instructions and examples, and the main library that plugins plugins use to interface with GIMP (called "libgimp") has a well-documented API. Good programmers, learning by modifying existing plugins, are often able to accomplish interesting things after just a couple Script-Fu. The scripts that come with Gimp can be quite useful, but they can also serve as models for learning Script-Fu, or at least as a framework and source of modification when you make your own script

A large component of learning how to use GIMP effectively is acquiring the art of making good selections—selections that contain [GIMP-DEV-PLUGIN].

segment an image from the XCT dataset of Al-Zn solidification using GIMP • In supervised machine learning, image- segmentation pairs are used for training Segmentation steps • Use the 852x852 pixel XCT the segmentation • Set the Opacity to 100 • File –> Export As… • The naming convention in machine learning is to keep the file name and add “_L” to signify that this is a labeled image • Name the segmentation
