The line colour is the colour used to draw the
outline. You can specify
one of the following:
Transparent
No
colour (the outline is
not drawn).
Colour
A single colour is used for the
outline. This can be specified as RGB (red
green blue), CMYK (cyan magenta yellow
black), HSB (hue saturation brightness)
or grey scale. The alpha value changes the opacity
(maximum value is solid, zero is completely transparent and a value
in between produces a semi-transparent effect).
Gradient
A two-tone
gradient is used
for the outline. This requires a start colour and an end colour.
The shading may be linear or radial: if linear, you need to
specify a direction using one of the direction buttons; if radial,
you need to specify the starting location using one of the buttons
provided.
Note that the colours you see on the
screen may not exactly match colours produced by your printer
due to the non-invertible mapping between colour spaces.
The colours are specified as integer values between 0 and 100,
or between 0 and 359 in the case of hue.
You can type in the number in the appropriate box or use
the slider bars or you can click on one of the predefined colour
buttons.
When exporting your image,
note that:
Gradient paint line colour is not implemented when exporting
to a LaTeX file: only the start colour will be
used.
The alpha value will be ignored if you export your image
as an EPS file. Similarly, if you export your
image as a pgfpicture environment, and then use LaTeX and
dvips, the resulting PostScript file will not implement any
semi-transparent effects.
All colours will be converted to RGB when exporting to a
PNG file, and the background will be set to white.
