A texture is a pattern used when filling areas to +get a texture rather than solid color. +@PP +In the PostScript world, textures are called patterns, and the +relevant PostScript commands use this terminology. The author +has preferred the term `texture' because it is more precise: +a pattern could be a pattern for anything. +@PP +The @@SetTexture command accepts the special value {@Code "nochange"} +for the left parameter.

An +empty left parameter also has this effect. +@PP +Another special value is {@Code "LoutTextureSolid"}, which means no +texture at all, just solid colour.

It is also +the initial texture; thus there is no need to ensure that the root +galley or each of its components is enclosed in a @@SetTexture symbol. +@PP +The form of the left parameter is implementation-dependent; in Basser +Lout it must be an object whose value is a sequence of words comprising +PostScript for setting a texture, up to and including the PostScript +@Code "setpattern" command (or equivalent) which installs the texture +into the graphics state. Lout makes no attempt to understand textures, +it simply prints the PostScript commands when appropriate.

You don't +have to use it if you don't want to. The above example of +@Code "LoutMakeTexture" sets the pattern matrix and dictionary as follows. +@PP +The first number is a scale factor, and the second and third are horizontal +and vertical scale factors. The fourth ({@Code "0 dg"}) is an angle of +rotation. The fifth and sixth are horizontal and vertical shifts. These +six numbers determine the pattern transformation matrix passed to +{@Code makepattern}. +@PP +The remaining elements go into the pattern dictionary. @Code "PaintType" +is set to the first of them, or the seventh item overall (2 in our example, +denoting an uncoloured pattern, which will usually be the best choice; +the pattern will be painted in the current colour), @Code "BBox" is set +to the eighth item, here {@Code "[0 0 2 pt 3 pt]"}, @Code "XStep" is set +to the ninth item, here {@Code "2 pt"}, @Code "YStep" is set to the tenth +item, here {@Code "3 pt"}, and @Code "PaintProc" is set to the eleventh +and last item, which should be an executable array as shown.

You must use +@Code "LoutSetTexture" and you must not use {@Code setcolorspace}, +@Code {setcolor}, and {@Code setpattern}, because Lout considers +colour and texture to be independent of each other, and these PostScript +commands don't. +@PP +Another advantage of @Code "LoutMakeTexture" and @Code "LoutSetTexture" +is that they behave sensibly on Level 1 PostScript interpreters, +which do not have patterns.

The default value +of {@Code labelradius} shown above, {@Code internal}, +is a synonym for 0.6, so it causes the centre of the label +to appear 60% of the way from the point of the slice to +its outside boundary. The angular position of the label +centre will be halfway around the arc of the slice. No +attempt is made to fit the label into the interior of +the slice; it lands where these rules say irrespective +of what might be overstruck when it does.

For example, +@ID -1px @Break @OneRow @Code @Verbatim { +@Slice + labeladjust { 0.2c -0.1c } +} +will move the label centre 0.2 centimetres further to +the right and 0.1 centimetres down from where it would +otherwise have appeared. +@PP +The recommended procedure for getting internal labels +to look good is to first try them without any adjustment. +Next, consider rearranging the label layout.

It can be replaced by any number. +@PP +Two issues arise when labels are placed externally. +The first issue is that Lout does not know where these labels +are being printed and so cannot leave space for them. +Section {@NumberOf pie_over} has already explained how to +handle this problem using the {@Code leftextra}, +{@Code rightextra}, {@Code aboveextra}, and {@Code belowextra} +options of {@Code "@Pie"}. Our running example, converted +to external labels, might be entered like this: +@ID -1px @Break @OneRow @Code @Verbatim { +@Pie + abovecaption { Ideal breakdown of academic workload } + labelradius { external } + aboveextra { 0.7c } + belowextra { 1.3c } +{ + @Slice + detach { yes } + weight { 20 } + label { Admin @LLP (20%) } + @Slice + weight { 40 } + paint { green } + label { Research @LLP (40%) } + @Slice + weight { 40 } + paint { lightred } + label { Teaching @LLP (40%) } +} +} +which produces this: +@CD @Pie + abovecaption { Ideal breakdown of academic workload } + labelradius { external } + aboveextra { 0.7c } + belowextra { 1.3c } +{ + @Slice + detach { yes } + weight { 20 } + label { Admin @LLP (20%) } + @Slice + weight { 40 } + paint { green } + label { Research @LLP (40%) } + @Slice + weight { 40 } + paint { lightred } + label { Teaching @LLP (40%) } +} +The amount of extra space to add has to be worked out by +experiment. It can help to temporarily remove all +captions and enclose the @Code "@Pie" symbol in a box +with zero margin: +@ID -1px @Break @Code @Verbatim { @Box margin { 0i } @Pie ... } +to show clearly how much space the @Code extra options +are covering. +@PP +The second issue raised by external labels is how to +visually connect each label with its slice, when this +fingers.pie @Index { fingers in pie graphs } +piegraphs. @RawIndex { pie graphs } +piegraphs.fingers @SubIndex { fingers } +seems necessary. @Code "@Pie" can do this with short +line segments that we will call {@I fingers}: +@CD @Pie + abovecaption { Ideal breakdown of academic workload } + labelradius { external } + aboveextra { 1.3f } + belowextra { 3f } + finger { yes } +{ + @Slice + detach { yes } + weight { 20 } + label { Admin @LLP (20%) } + @Slice + weight { 40 } + paint { green } + label { Research @LLP (40%) } + @Slice + weight { 40 } + paint { lightred } + label { Teaching @LLP (40%) } +} +These were made by adding @Code "finger { yes }" as +another option to the @Code "@Pie" symbol. +@PP +Each slice has several options which control the +appearance of its own finger.

The first bit, +@ID @Code "+3p @Font @S @Name" +produces the term being defined, three points larger than would +have been the case otherwise, and in small capitals. The +@Code "@Right" symbol causes what follows it to appear at the +far right, so +@ID @Code "@I { @Word&&page @PageNum }" +will appear at the right of the column on the same line as +the term. The value of {@Code "@Word&&page"} is just +{@Code page} in the current language, and @Code "@PageNum" is a +page number as we know, so this produces something like +@ID @I { page 143 } +at the right. After that we have {@Code "@DP"} which leaves +a display-sized vertical gap, then the body appears in an +indented display, made Raw so that there is no trailing +vertical space. +@PP +You can change this option to anything you like. For example, +suppose you prefer bold to small capitals, you want the page number +in parentheses after the term, and you want each entry to be +kept together in one column: +@ID @OneRow @Code @Verbatim { +@GlossaryFormat { + @OneRow { + @B @Name (@I { @Word&&page @PageNum }) + @DP + @RawIndentedDisplay @Body + } +} +} +And so on. +@PP +There are a few more setup file options for glossaries, to be found +in the {@Code "@BookSetup"} or {@Code "@ReportSetup"} @Code "@Use" +clause of the setup file. Here they are with their default values: +@ID @OneRow @Code @Verbatim { +@GlossaryWord { glossary } +@GlossaryInContents { Yes } +@GlossaryPrefix {} +} +The first determines the word that will be used as the title of +the glossary. The default value shown produces {@Code Glossary} +in English and its equivalent in other languages.
