Editing can be made easily with a graphics software, e.g., Adobe Illustrator. Files can be resized without any loss of quality. Fonts may become corrupted or substituted when they are not embedded within the image. Scanned art should be supplied at final size. See Final Display Sizes .
Monitors display information in pixels.
At this time, there is no package that supports or allows for the on-line presentation of vector images. GIF and JPG cannot be used for print production because of their low resolution. The images would appear both jagged and blurry. Scanned line art is not recommended because it generally does not reproduce well. The curve of the book will cause distortions, and artifacts such as smudges and blurs will become part of the scanned graphic.
