XyzzyText is a new version of Xytext with some advanced features:
- Efficiency! You can now control an entire linkset with just one script.
- Flexible Speed vs Lag. Just drop in plug-and-play slave scripts to increase rendering speed. (More than 4-5 slaves not recommended, there is diminishing returns)
- Ease of use. There is no need to know link numbers. Simply name the child prims xyzzytext-banknumber-cellnumber.
- To use, pass the bank number to use in the "key" field of the link message of DISPLAY_STRING/EXTENDED.

XyzzyText - 5 Character
Example:
Display Prims named: xyzzytext-0-0 xyzzytext-0-1 xyzzytext-1-0 xyzzytext-1-1
Quickstart:
* Store all scripts in your inventory * Rez a box * Drop the prim setup script in it (You now have one unit, name it xyzzytext-0-0) * Make a row of four of these prims (xyzzytext-0-0 xyzzytext-0-1,xyzzytext-0-2,xyzzytext-0-3) * Move a copy of this row a little down, and rename the new row(xyzzytext-1-0 xyzzytext-1-1,xyzzytext-1-2,xyzzytext-1-3) * Do this for every row you make * Create a big box that serves as the board-background(mainprim) * Link all prims with the mainprim(selected last), so the mainprim keeps yellow after linking(root-prim) * Copy the main script and usage script into the root prim * Type something, and check if it all works * Flatten the prims, so the text looks straight * Consider adding slave scripts to the root prim if you have a lot of rows

How to produce textures with alternative fonts for 5 character version (Photoshop VBscript version)
Note: If you need to use XyzzyText for European or UTF-8 other languages, please see the following link: XyzzyText-UTF8 Use the following section for GIMP script-fu if you prefer opensource alternative. Use the following link: ZZText for an alternative international solution (still based on xytext and xyzzytext) using even fewer textures and lag than the xytext solution.
If you need to display with another font, italics or other characters, you can do the following :)
Using Photoshop VB Scripting on windows, just open up Photoshop CS3, and create with notepad the following MakeFonts.vbs:
Dim appRef
Set appRef = CreateObject( "Photoshop.Application" )
' Remember current unit settings and then set units to
' the value expected by this script
Dim originalRulerUnits
originalRulerUnits = appRef.Preferences.RulerUnits
appRef.Preferences.RulerUnits = 1 ' psPixels
' Create a new 512*512 pixel document and assign it to a variable.
Dim docRef
Dim artLayerRef
Dim textItemRef
dim rows(10)
rows(1)=" !""#$%&'()"
rows(2)="*+,-./0123"
rows(3)="456789:;<="
rows(4)=">?@ABCDEFG"
rows(5)="HIJKLMNOPQ"
rows(6)="RSTUVWXYZ["
rows(7)="\]^_`abcde"
rows(8)="fghijklmno"
rows(9)="pqrstuvwxy"
rows(10)="z{|}~·ΘΩ√"
dim fontname
fontname="Courier"
Set docRef = appRef.Documents.Add(512, 512, 72, "Table for font " & fontname, 2, 3, 1)
' Create a new art layer containing text
Dim colorObj
Set colorObj=CreateObject("Photoshop.SolidColor")
colorObj.RGB.Red=255
colorObj.RGB.Green=255
colorObj.RGB.Blue=255
' Set the contents of the text layer.
for i=1 to 10
for j=1 to 10
Set artLayerRef = docRef.ArtLayers.Add
artLayerRef.Kind = 2
Set textItemRef = artLayerRef.TextItem
' textItemRef.Font = fontname
textItemRef.Color=colorObj
textItemRef.Justification = 2
textItemRef.Font = "A Charming Font"
textItemRef.Size = 38
textItemRef.Contents = mid(rows(i),j,1)
textItemRef.Position = Array((j-1)*51.2+25,i*51.2-7)

Just click on the file in internet explorer and it will start working with your photoshop (I'll take a bit to display all the 100 characters, maybe around 1 sec for character).
This will layout the 100 characters in photoshop on 100 different layers. Then do the following:
- select all the layers with text and go to Text tool and change to whatever font (size etc) you want
- maybe need to add a black layer to see your fonts :) (after you have to hid or delete this)
- merge all the layers in just one
- add an alpha channel for transparency (all black)
- select all in the merged text layer and copy it to alpha channel
- enable the alpha channel and the RGB channel so that you see your font set and the transparent red
- save the font as TGA preserving alpha channel
- upload it to SecondLife 10 L$
- get the UUID from the inventory and specify it instead of the standard template.
How to produce textures with alternative fonts for 5 character version (GIMP script-fu version)
Use the following script for generating characters with GIMP:
To use it you must put under the $HOME/.gimpXXX/scripts directory and name it something.scm. Then you will find it under gimp <Toolbox>/Xtns/Script-Fu/Text. Clicking on it you are prompted for font to use (use monospaced fonts Andale Mono for instance). (Change only font and fontsize 50 should be ok, others are hard-coded in the script). Adapt with new unicode characters if you need them.
Note: If you need to use XyzzyText for European or UTF-8 other languages, please see the following link: XyzzyText-UTF8 Use the following section for GIMP script-fu if you prefer opensource alternative. Use the following link: ZZText for an alternative international solution (still based on xytext and xyzzytext) using even fewer textures and lag than the xytext solution.
