The Size of Digital Imaging: Resolution

  • Wallace Jackson


Now you have an understanding of the pixel building blocks that make up raster images as well as what the difference is between a raster image that is 2D and pixel based, and a vector image that is 2D (or 3D), and vertex and line (or curve) based. In this chapter, we build on these concepts by looking at the x and y dimensions of digital image compositing. Since you now have GIMP downloaded onto your computer, I will illustrate concepts in the book using both Photoshop and GIMP, as those are the most widely used digital-image packages.
