Over the years many other people have contributed by helping with development, testing, providing support, translating and writ- ing documentation. GIMP releases are currently being orchestrated by Mitch • Sub-pixel sampling for all paint tools for high-quality anti-aliasing. • Full Alpha channel support for working with transparency. • Layers and channels. 3 CHAPTER 1. INTRODUCTION 1.2. WHAT’S NEW (limited only by disk space). • Transformation tools including rotate, scale, shear and flip. • Support for a wide range of file formats, including JPEG, PNG, GIF, PSD, DDS, XPM, TIFF, TGA, MPEG, PS, PDF

Page 2 1.2. Raster Image Formats There are two main kinds of graphics: raster graphics and vector graphics. Raster (or bitmap) graphics is to represent graphics into small rectangular points points called pixels. Raster graphics is suitable to store digital photos. In contrast, vector graphics is to represent graphics into geometric objects like lines, curves, polygon, etc. These objects 1.

Manipulation Program • Bitmap Graphics Editor • Open Source • Cross Platform • Not for Vector editing www.gimp.org Vector vs Bitmap Getting GIMP • Open Source • Cross Platform www.gimp.org • View Toolbox Images • Useful to crop unnecessary edges away • Can reduce file size when bringing images into a vector file • Use the ‘Rectangle Select’ tool (R) to draw a box around the area of the image you

manually 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 Saving 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

operations and many types of displays from 8 bit to 24 bit. Newer beta versions of the program support layers, transparency, and scripts to automatically generate logos and other images. Soon the program
