FONTS

Each text string should have a single font associated with it. That font may be either a print font or a screen font. For our purposes here, a font is a collection of shapes, defined in some font coordinate system, together with a transformation to apply to a string of those shapes when the string is rendered.

File Format

Ignoring user interface for the moment, here is what we will store in .gargoyle files: If the font is a resolution-independent font (e.g. press font), we store:

FontPrefix FontFamily Face Transformation Preferred Size

Xerox/PressFonts/ Helvetica -BI M = [a, b, c, d, e, f] 1.0

Xerox/xc1-2-2/ Modern -BI M = [a, b, c, d, e, f] 1.0

The shapes of the font are assumed to be 1 unit large in font master coordinates. If the named FontPrefix/FontFamily does not obey this property, the font will be scaled to be a unit font before the Transformation is applied. Hence, if M = Scale[12], the font will appear as 12 screen dots high. Our units are 1/72.0 of an inch. Tioga uses 1/72.27 inches. Life is hard.

If the font is a resolution-dependent font (e.g. screen font, like Tioga10), we store:

FontPrefix FontFamily Face Transformation Preferred Size

Xerox/TiogaFonts/ Tioga -BI M = [a, b, c, d, e, f] 10.0

The shapes of the font are assumed to be 1 unit large in font master coordinates. This is often not true. However, the font will be scaled to be a unit font before the Transformation is applied. Gargoyle will have to know about fonts, but can hide this knowledge from the user. For instance: CMR10 is a 1 unit font, which must be scaled by 10 to look good. Tioga10, however, is stored at 10 units high in font master coordinates. Gargoyle will scale it by 0.1 to get a unit font, but M will usually be Scale[10] so all will be well.

We store both kinds of fonts in .gargoyle files using the same format with Preferred Size = 1.0 for press fonts. This is a unique value which signals the fileIn code that it is a resolution independent font. It's size is one unit, and the appearance scaling is in the transformation.

User Interface for Output

There will be a "look readable" mode which calculates a more readable font from the font in each text string. As we do now, we will probably cache this font in each string along with the "real font". However, the readable font will not necessarily be a Screen Font. For large strings, it may be the same as the real font, for instance.

Setting Fonts

Here's where we have to be flexible. We'll probably want to have several kinds of SetFont commands, some which are convenient for everyday use and some which let you be very specific. These four may make a good starting set:

SetPressFont. The user selects a <FontFamily-FontFace> <scalar> pair such as "Helvetica-BI 12". The <-FontFace> may be left off, denoting regular font. Gargoyle assumes FontPrefix = Xerox/PressFonts/ and lets transformation M = Scale[<scalar>]. The font is made with ImagerFont.Scale[font, 1] (in all cases I know about).

SetPrintFont. The user selects a <FontFamily-FontFace> <scalar> pair such as "Helvetica-BI 12". The <-FontFace> may be left off, denoting regular font. Gargoyle assumes FontPrefix = Xerox/XC1-2-2/ and lets transformation M = Scale[<scalar>]. The font is made with ImagerFont.Scale[font, 1] (in all cases I know about).

SetScreenFont. The user selects a <FontFamily-FontFace> <preferred size> pair such as "CMR 10". Gargoyle assumes FontPrefix = Xerox/TiogaFonts/ and lets transformation M = Scale[<preferred size>]. The font is made with ImagerFont.Scale[font, 1] if the font is CMR, with ImagerFont.Scale[font, 1.0/<preferred size>], if the font is Helvetica, TimesRoman, Tioga. If the font is one of the traditional TiogaFonts (e.g. Helvetica, TimesRoman, Tioga, ...) Gargoyle will attempt to find the corresponding strike font. For example, SetScreenFont TimesRoman-BI 9 will find the font in file ///fonts/xerox/tiogafonts/TimesRoman9BI.ks. If the user requests a TiogaFont not in the Tioga font set (usually an odd size), Gargoyle will fail to change the font. I don't know which camp Terminal is in. At any rate, Gargoyle will have to keep track of which fonts are in which camp.

SetPrintFontDetailed. The user selects a <FontPrefix> <FontFamily-FontFace> <Transformation> triple. Gargoyle makes no assumptions. The user must provide a factored transformation. For example:

xerox/pressfonts/ gacha-bi [r1: REAL, s: VEC, r2: REAL, t: VEC]

xerox/xc1-2-2/ classic-b [r1: REAL, s: VEC, r2: REAL, t: VEC]

WHITESPACE IS CRITICAL !!

SetScreenFontDetailed. The user selects a <FontPrefix> <FontFamily-FontFace> <Transformation> <Preferred Size> quadruple. Again, Gargoyle uses its information about font camps to successfully make a unit sized font. Otherwise, Gargoyle makes no assumptions.

Note: For screen fonts, we may run into trouble when <scalar>*(1.0/<scalar>) isn't quite 1.0. We can either round within epsilon for screen fonts, or we can keep around an unscaled font when we know we should be hitting the fast case.

Asking About Fonts

A single function PrintFontOfSelected should say exactly what font is being used. The format of this output should be suitable for selecting and feeding to SetPrintFontDetailed or SetScreenFontDetailed. Unfortunately, the Gargoyle feedback region isn't selectable. Of course, the user could open a Typescript first. Suggestions?
