TtoDInstr

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
This file describes the commands which can be used with the Bio module
TtoD.

units <mm|inch>
Change the units that co-ordinates are specified in. Either
millimetres (mm) or inches (inch).

font -number <no> -name <name> -size <size>
Specify the local font. The number is the internal Draw file font
number. The name is the Risc OS font  name, such as Trinity.Medium.
The size is the point size of the text. If you have defined a font
previously in the same file, just put �font -number <number>�  to
recall the definition.

line -start <x,y> -end <x,y> [-width <w>] [-line <&BBGGRR00>]
Draw a line. Start and end parameters are in x,y format (e.g. -start
10,10). The width is  the line width that will be used. Zero
represents the thinnest line the device can produce. The colour is a
hex number, the format of which is &BBGGRR00, so colour &2020ff gives
a lightish red colour.

rectangle -first <x,y> -second <x,y> [-width <w>] [-line <&BBGGRR00>] [-fill <&BBGGRR00>]
Draws a rectangle. The co-ordinate pair can be specified any way you
like, as long as the two co-ordinates represent opposite corners.
Width and colour as above.

sprite -first <x,y> -second <x,y> -file �file� -name �name�
Reads in a sprite from file �file� and displays sprite called �name�
in the file. The first and second co-ordinates specify the bounding
boxes.

ltext -x <x> -y <y> [-path] -text �text�
Displays the text in the text parameter at the specified x,y
co-ordinates; the x,y are at the bottom left. The path parameter
converts the text to a path (Risc OS 3 only)

ctext -first <x,y> -second <x,y> [-path] -text �text�
The text centred vertically and horizontally in the box, with optional
conversion to a path. (Again, path parameter is Risc OS 3 only).

ellipse -centre <x,y> -horz <x> -vert <y> [-line <&BBGGRR00>] [-fill <&BBGGRR00>]
Draws an oval (ellipse), centred at the specified co-ordinates, with
major and minor diagonals specified by horz and vert.

path  [-width <w>] [-fill <&BBGGRR00>] [-line <&BBGGRR00>]
Starts a path object

move -to <x,y>
Moves the �cursor� in the path object.

draw -to <x,y>
Draws a line in the path object.

curve -to <x,y> -first <x,y> -second <x,y>
Draws a bezier curve to the specified co-ordinates, using first and
second as control points.

close
Close the path.

end
End the path object.
