Painting in Image
-----------------
Painting within Image is designed primarily for touching up and adding
to existing pictures, rather than creating new pictures from scratch.
As such Image adopts a rather unusual approach to painting, but one
which is very powerful.
When you select the 'Paint' icon on the control panel, two things
happen. First the 'Paint Control' window opens, but also an image
'overlay' is created. This overlay is in fact a 16 colour sprite, the
same size as the current display picture, which is placed over the
display window picture (although it is initially transparent).
Any paint operations you perform are actually done to that sprite (the
main picture is untouched). When you have finished painting you can
then merge the overlay with the main picture using any merge operation
available on the 'Merge Operations' control window (including the mask
creation operations).
Brushes
-------
The Paint operations in Image include 3 different brushes; square,
circular and spray can. These three brushes can have any size, from 1
pixel size upwards (this is selected by the 'Size' icon). The spray
can also has an extra parameter, density, which determines how quickly
the spray can works. Also there is a pencil 'brush' which can be selected,
however this brush has a fixed width (single pixel). Finally there is a flood
fill paint can, which flood fills over a colour in the overlay.
To paint simply select the brush you require, and set the size, etc.
Then using the 'Colour Selection' window select the colour you require
(see 'Colour Selection' for details) and move the mouse pointer over
the display window and press (and hold) SELECT. Whilst you hold the
mouse button the brush will be applied (following the mouse pointer)
with its centre being under the mouse pointer.
If, instead of holding SELECT, you use ADJUST the brush changes into
an eraser (having the same shape and size as the brush) which will rub
out areas of the overlay (thus exposing the main picture again). This
is one of the highly useful features available due to the 'overlay'
approach of Image - no matter how much you paint into an overlay you
can rub out any amount. Note, this ADJUST behaviour extend to the flood fill,
except here it will remove all connected parts from the overlay.
Shapes
------
As well as brushes there are also 'shapes'. These comprise of lines, circles,
rectangles, ellipses, and parallelograms. These shapes are added (as in
'!Paint') by pressing SELECT on the first point of the shape (corner, or
centre) and then the shape will 'rubber band', following the mouse pointer
until SELECT is pressed again (some shapes require 3 presses).
As standard the shapes are filled, but selecting the 'Outline' option makes
the shape outline only be drawn. Also setting the 'Erase' option causes the
shape to be used as a rubber. Pressing ADJUST while rubber-banding causes the
current operation to be abandoned.
Text
----
You can insert text into an overlay, using any available outline font. To
place text in the overlay first select the font you require by selecting the
menu icon at the top left of the 'Text' section of the Paint Control window.
This brings up a standard font menu, simply select the font you require and
its name will appear in the icon at the top of the 'Text' section.
Now you need to enter the size and angle of the text. The size refers to the
point size of the text, next to this is an icon for entering the X:Y ratio
for the text. Next to this is an icon for specifying the angle (in degrees)
of the text.
Finally enter the desired text in the icon at the bottom of the 'Text' section
and select the 'Font' brush icon (top left of the 'Text' section). Now
pressing SELECT over the picture display window will enter the text starting
at the position of the click. As with the brushes, clicking ADJUST turns the
text brush into an eraser.
Control
-------
If you want to clear the overlay, simply select the 'Clear' icon in
the paint control window. The 'Save' icon will save the current
overlay out to a special file which can be loaded with the 'Load'
icon. The 'Cancel' icon closes the paint control window, first
performing a 'Save'. The close window icon to the left of the title
bar will close the paint window but does not save the current
overlay.
The 'Apply' icon will perform an 'Over Merge' (this is the same as using the
merge control window with the 'Over' operation). Pressing SELECT on the
'Mask' icon will add the current overlay drawing to the image's mask, whilst
using ADJUST will subtract it from the mask (these perform the same operation
as the merge window's 'Add' and 'Sub' mask operations).
Important Notes:
1) Whilst the 'Paint' window is open some operations in Image are not
allowed. If you try to perform an operation which is not allowed you
will be warned that you can not perform that operation whilst in the
middle of a paint operation.
2) Closing the 'Paint' control window using the 'Abort' option destroys the
overlay completely.
3) When you perform a 'Merge' using the overlay, a 'Save' is
automatically performed before the merge, and the overlay is cleared
after the merge.
