A scalable helvetica >postscript font is the same font at all sizes. Not true. Adobe, and others, have sometimes misused the word "font," applying it to what is correctly callled a typeface. You don't scale a font; you scale a typeface in the process of rendering a font (see below). >Traditionally, when you scale a typeface (in particular, make it >smaller) you're supposed to change its appearance to improve >readability. Not quite. When you create a font from a typeface (a process which is called "rendering"), you may choose to employ tricks such as anti-aliasing. The purpose of these tricks is not to change the appearance of the typeface but rather to preserve it! Most of these tricks deal with the pixellated nature of modern computer displays. Some of them even employ sub-pixel rendering; see http://grc.com/cleartype.htm --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
