!Draw 2.19 (05 Nov 2002)
=====


Introduction
------------

The Draw application allows you to create and edit
structured drawings that contain lines and curves,
and also text and images imported from Edit and
Paint.

Note:
  This version of Draw has been modified to support
  Sprites greater than 28 MB using Dynamic Areas.
 
  To set largest Dynamic Area you can change the value
  in the !Run file.

  For example :
    Set Draw$DALimit 30M
  sets to a maximum 30MB Dynamic Area uasge.


Draw configuration
------------------

You may wish to change some aspects of the way new
Draw windows appear. For example, a new window
normally opens with the closed line tool selected, but
you may prefer to have the circle tool ready to use
each time you start Draw.

You can set features of this type by setting up Draw
as you wish to use.

There are several features of Draw that you can set so
that they appear the way you want them each time you
switch on. The Draw features that will be recorded
when you go through this process are known as
Draw$Options.


Letter: Feature controlled: Possible values and their
meaning:


 P: Paper size and format: n = paper size An (e.g.
     A4), L = landscape format (if not set, portrait
     is used), S = Show paper limits

 G: Grid: a x b where a = spacing, b = subdivisions,
     I = Isometric (rectangular if not set), A = Auto-
     adjust on, S = Show grid, L = Grid lock on, C =
     cm units (inches if not set)

 Z: Zoom: a:b : Set zoom to a:b, L = Zoom lock on

 T: Toolbox display: + or -: Toolbox on or off

 M: Tool/mode selected: One of: L l C c R E T S ,
     where L = Line, l = Closed line, C = Curve,
     c = Closed curve, R = Rectangle, E = Ellipse,
     T = Text, S = Select

 J: JPEG rendering: N = no dithering, D = dithered,
     E = dithered and error diffused.

  
Default settings
----------------
The default settings used by Draw are as follows:

 P4: A4 portrait format, paper limits not shown

 G1x4A: 1 inch rectangular grid with 1/4 inch
         subdivisions, not shown or locked, auto-
         adjust on.

 Z1:1: Zoom 1:1, zoom lock off.

 T+: Toolbox on.

 Ml: Closed line tool selected

 JD: JPEGs dithered

  
Increasing the Undo buffer size
-------------------------------
When you make a change to your diagram, such as
deleting an object, Draw stores the previous state of
the diagram in a buffer (area of memory) so that it
can restore it if you use the Undo option. This buffer
has, by default, a size of 5KB. Experienced users of
RISC OS may wish to use the Command Line to increase
the size of the buffer. To do this, enter the Command
Line and type

Set Draw$Options Un""

substituting for n the size you want, in bytes (must
be divisible by four).
