As noted earlier the default font at normalsize isa SANS serif font at size 20pt unless one of the 17pt 25pt or 30pt options have been declared in the documentstyle command Table 2 shows the control sequences for other accessible text fonts and the name of the font in a sample of its type These control sequences give the font at the current size Font size changing commands for each of the normal point size options are described by Table 3 Note that bf and s1 yield sans serif fonts not the usual variations on roman Table 2 Available fonts and their names command font names Mathematics is also automatically displayed at normal size unless magnified by a size changing declaration Table 4 describes the font point sizes for T X s mathematics styles at each of the normal point size options FoilT X loads or knows about enough fonts particularly symbol fonts that there should never be a discrepancy between the size of text and mathematics at any of the different sizes unlike IAT X where some fonts at xxvpt are actually only 20pt fonts Since many of FoilTEX s fonts are not in the standard distribution and so not available on most systems the installer will probably have to run METAFONT to generate the necessary files The file foilfont tex requires a sample of every preloaded or load on demand font and so can be used to test an installation s font availability Some drivers like Tomas Rokicki s dvi2pdf with dvips pr

6. alignment environments like tabular and eqnarray local color commands cannot extend beyond the alignment characters Because local color commands respect only some environment and delimiter changes besides their own care must be taken in setting their scope It is best not to have then stretch too far 5 4 User Definable Colors There are two ways for the user to specify colors not pre defined For local changes there is the command Color which takes two arguments The first argument is a quadruple of numbers between zero and one and specifies the intensity of cyan magenta yellow and black CMYK in that order The second argument is the text that should appear in the given color For example if a user wants the words this color is pretty to appear in a color which is 50 cyan 85 magenta 40 yellow and 20 black they would use the command Color 5 85 4 2 this color is pretty For global color changes there is a command textColor which takes one argument the CMYK quadruple of relative color intensities For example to make the default color to be as above then the command textColor 5 85 4 2 The text from now on will be this pretty color will suffice If the intended output device does not treat color in CMYK terms then the device driver should convert these values to the device dependent parameters e g RGB 5 5 Setting The Background Color There is an additional macro for setting the background color
7. mechanisms as in ATpX We have set the defaults however so that at the highest level there is a fair amount of vertical space but at lower levels this shrinks to nothing This seemed to produce the best and most pleasing results at least to the author s personal taste 3 8 This Is Not IAIpX At the heart of Foil TEX is a format file Consequently there is usually a system dependent exec or script or batch program which calls the main T X program with the necessary FoilTpX format file fltplain fmt Testing showed that users especially hard core IATFX users tended to run IATpX instead out of habit As a result a special feature was implemented in which if ATX is called on a FoilT X file the user is prompted with a warning and given a choice of continuing with some unpredictable consequences or aborting 3 9 AMS Fonts Included with FoilT X is the style file anssymbl sty which can be used with either FoilTfX or IAT X with the old font selection scheme This style loads the AMS T X symbol fonts from the msam msbm and eufm fonts at all the necessary magnifications for the appropriate format It adds to the existing font data for these formats in such a way that the standard size changing mechanisms work correctly on these symbol fonts To use this file you must have both amssym tex and amssym def from the AMSFonts package version 2 0 or greater as well as the actual fonts and tfm files There are three things to note First

9. to protect sensitive regions of the text To give an example in IAT FX files one might make sure that the header and footers have globalColor wrapping their contents In this way they will inherit the current active de fault global unnested color state In Foil TEX we chose not to do this effect but to wrap headers and footers in black since it was presumed that in these regions on foils they should retain a constant color always 16 Furthermore to correct the list environment problem described above the item command in FoilT X is redefined from its IAT X version by wrapping the item label by the globalColor macro In this way at least in FoilT X item labels will appear as one should expect 6 Installing FoilTRxX Because installations of TeX IATpX differ so much from system to system and even within systems e g there a numerous TFX packages available for DOS systems these installation instructions are mostly just an outline of the general procedure It is hoped that your local T Xperts or your own T X installation instructions will be sufficient to fill in any gaps not handled by these instructions In the following subsections we outline the installation procedure for VM CMS UNIX and DOS In every case there are some basic assumptions made about your installation of T X IAT X These are 1 2 You must have TEX IAT X installed including a version of initex and a copy of latex tex You sh

11. It takes a single argument which can either be one of the predefined color names or a quadruple of CMYK values For example background SkyBlue or background 1 2 3 1 15 These should appear somewhere on the page preferably near the beginning where the background color is to change The background should stay this color until explicitly changed by another such command It should be remembered that the placement of this is sensitive to the output routine 5 6 Protecting Regions From Spurious Colors Because color is defined via T X s special command it cannot be sensitive to the output routine or certain regions of the page like the header and footer Consequently these regions need to be protected from spurious color changes particularly when local colors spread across page breaks This is true in FoilT X as well as in any other version of TeX The default color should always be black of course and this is what happens in Foil TEX and what dvi2pdf with dvips initializes The header and thepfSoaer defhoillted to always also be black even if the text global color changes Consequently the contents of MyLogo Restriction rightfooter the page number by default leftheader and rightheader will all appear in black Overriding the color selection for any of these regions of the text in FoilT X can be done by using local color commands in their declarations For example a very sensitive talk requiring the words

Need To Know in red would use the declaration Restriction Red Need To Know In other T X s user s need to be aware of the possibility of certain regions getting unwanted or unpredicted colors Headers and footers are most worrisome so style designers who want to use color should keep this in mind One particular region of text that gets spurious color effects is labels in list environments Because of the way list items are defined in standard IATpX the following situation can occur begin itemize item This is the default color black item Red This is Red because we nested a red command end itemize In this example one would expect that the labels normally bullets for these items would both be black Unfortunately that is not the case The label of the second item will in fact be red To give the user a simple mechanism to solve this problem and other unforeseen effects of this type one other special macro is automatically defined This macro is called globalColor It is actually a local color macro and so takes a single argument But the color effect it produces is always the same as that set by the last textColor or text ColorName type command In effect when a textColorName command is called globalColor gets a new definition equivalent to the local ColorName macro For example when the default is black globalColor Black and when textGreen appears globalColor Green This special macro can then be used

15. ack White With Or Without blackdvi sty A Foil T X or other TEX document written with color macros can be printed in black and white in two ways If the device is a black and white version of a color device e g display or POSTSCRIPT printer then it should print in corresponding grey levels This is useful since in this way one can get a rough idea of where the colors are changing without using expensive color printing devices The second option is to replace the call to input colordvi with blackdvi This black style file turns all the color macros into no ops and so will produce normal black white printing without the user having to ferret out the color commands Also most device drivers will simply ignore the color commands and so print in normal black and white 5 3 The Color Macros User s Viewpoint There are two kinds of color macros ones for local color changes to say a few words or even one character and one for global color changes All the color names use a mixed case scheme There are 68 predefined colors with names taken primarily from the Crayola 64 crayon box and one pair of macros for the user to set his own color pattern More on this extra feature later There is one other special macro which we will describe later in Section 5 6 Users can browse the file colordvi sty for a list of the predefined color names A local color command is in the form ColorName this will print in color As this example shows this

19. e first is bm formula This takes it argument within mathematics mode and replaces it with it emboldened version Unfortunately it acts a little funny on characters like summation signs and in super or subscripts partly because it reverts to T X s text style style T first by enclosing the subformula in an mbox Consequently this command should be used primarily on individual characters or small parts of formulas A more natural syntax for this command ought to be bm formula but the author could not find a way to implement the same effects in this way The second method for getting bold mathematics is a pair of environments begin boldequation formula end boldequation begin boldequation formula end boldequation They both set formula in bold except for super and subscripts The unstarred form has automatic referencing and is numbered the starred form inhibits the numbering and referencing The limitation on the super and subscripts not appearing in bold face is strictly to limit the number of fonts loaded by FoilT X In the definition of boldmath the scriptfont and scriptscriptfont styles are not redefined for any of the math font families It was felt this bold math feature would have limited use and so it is not fully supported If there is sufficient demand it could easily be extended 3 7 List Environments The vertical spacing of items in list environments is controlled by exactly the same

40. type of command takes one argument which is the text that is to print in the selected color This can be used for nested color changes since it should restore the original color state when it completes For example suppose a user was writing in green and wanted to switch temporarily to red then blue back to red and restore green Here is one way to do this This text is green but here we are Red switching to red Blue nesting blue recovering the red and back to original green In principle the nesting level is unlimited but it is not advisable to nest too deep lest one loose track of the default color or exceed the driver s capacity The global color command has the form text ColorName This macro takes no arguments and immediately changes the default color from that point on to the specified color This of course can be overridden globally by another such command or locally by local color commands For example expanding on the example above we might have 14 textGreen This text is green but here we are Red switching to red Blue nesting blue recovering the red and back to original green textCyan The text from here on will be cyan unless Yellow locally changed to yellow Now we are back to cyan The color commands will even work in math mode and across math mode boundaries This means that a color state going into math mode will force the mathematics to be set in that color as well More importantly however in
