Chameleon
=========
© 4Mation 1992
This demonstration version of Chameleon may be freely distributed.
-------------------------------------------------------------------------
Chameleon is a Drawfile utility which allows you to change the colours in
Drawfiles easily.
Use the Interactive Help application which is provided in the Archimedes
Applications suite to provide help on Chameleon's facilities.
-------------------------------------------------------------------------
Operating Instructions
======================
To use Chameleon:
1. Load Chameleon by double-clicking on the !Chameleon icon.
2. Drawfiles can be loaded into Chameleon by dragging them onto the
Chameleon icon on the icon bar.
3. Use the toolbox and/or menu to select the operation to be performed.
4. Clicking on an object in the picture will apply the current operation
to that object.
5. Clicking on an object with Adjust will take the colour from that object
(where you clicked) and use it as the current replacement colour.
The Toolbox and Colour Selector
===============================
If the toolbox is not displayed, move the pointer into the Chameleon window
and press F6.
If the colour selector is not displayed, click on the colour box in the
bottom right corner of the toolbox.
Changing colours
================
Make sure that the tool on the left hand side of the middle row in the
toolbox is selected. Choose a colour from the colour selector. (Use the 256
colour palette if you are in a 256 colour mode.)
Click on an object in your picture and its colour will be changed. If the
object has no fill colour, select the fill tool at the right hand side of
the bottom row of tools. This allows you to change the fill colour and leave
the line colour unchanged. The outline tool (next to the fill tool) allows
you to change the line colour whilst leaving the fill colour unchanged.
Fountain fills
==============
The four tools on the left hand side of the bottom row in the toolbox
provide fountain fills. When you select one of these tools, an arrow appears
on the colour box. To select a start colour, click on the left side of the
box and then choose a colour. To select an end colour, click on the right
side of the box and then choose a colour. Fountain fills give a range of
shades between these two colours. Even a 256 colour mode, however, is
incapable of displaying the complete range of colours although RISC OS 3
machines are capable of displaying more than 256 colours by using a
dithering technique.
Drag an arrow across the object-to-be-filled and then click on the object to
implement the fill. There is a different arrow for each tool.
Linear fill: an arrow with a start point and end point. The fountain fill
extends from the start point to the end point.
Band fill: an arrow with 4 movable end points. The fountain fill extends
in both directions between the two pairs of end points. Moving the inner
end points sets the width of the start colour band.
Radial fill: an arrow with 2 movable end points. The fountain fill extends
from the inner circle to the outer circle.
Elliptical fill: two arrows, one with 1 end point and the other with 2.
The fountain fill extends from the inner ellipse to the outer ellipse.
The arrows can be moved to a different position by holding down Shift and
dragging one of the points.
If you hold down Ctrl whilst moving the arrows, movement is restricted to
steps of 15°. This also allows arrows to be perfectly horizontal or
vertical.
Other tools
===========
The tools in the second row (from left to right) have the following
functions:
Replace: changes the line and/or fill colour to the current colour
Change hue: changes the colour to the hue of the current colour
Make grey: changes the colour to a shade of grey
Brighten: brightens the colour by decreasing the amount of black
Darken: darkens the colour by increasing the amount of black
Weaken: weakens the colour by increasing the amount of white
Strengthen: strengthens the colour by decreasing the amount of white
Target area
===========
The top row of tools allows you to define the target area affected by the
colour-changing operations. The tools (from left to right) have the
following functions:
Local: only the object beneath the pointer is affected
Global: all objects having the same colour as the object beneath the pointer
are affected
Within box: a box may be dragged into position, colour changes apply to all
objects which are entirely enclosed by the box
Beneath box: changes are applied to all objects which are wholly or
partially enclosed by the box
Not within box: changes are applied to all objects which are completely
outside the box
Keyboard shortcuts
==================
Shift Affects the outline:
When the colour of a thin line is to changed, it may be difficult
to position the pointer accurately. If Shift is pressed at the
same time as clicking Select or Adjust while the pointer is over
the object, the operation will act upon the line.
The effect is the same as when the outline tool is selected.
Ctrl Affects the fill:
When an object has no fill colour, or the filled area is very small,
Ctrl should be pressed at the same time as clicking Select or Adjust.
The pointer should be moved as close to the line as possible.
The effect is the same as when the fill tool is selected.
For Text objects, and text areas, pressing Ctrl during a click will
treat those objects as if their bounding boxes were solid colour.
For Sprites, pressing Ctrl will ignore any mask.
Arrow The arrow keys move the pointer in steps of one pixel.
