No color. A
transparent is not painted on the
canvas, but it does have a . When exporting to a LaTeX document, transparent text areas have their text set in the
argument of \phantom.
Color
A single color. This can
be specified as RGB (red green blue),
CMYK (cyan magenta yellow black),
HSB (hue saturation brightness) or
gray 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 colorand an end color. 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.
If you intend to save your picture as a pgfpicture
environment, there is no implementation of gradient color for text.
If you have a with a gradient text color,
then when you save it to a LaTeX file, the starting color will be applied as a single color. If you want gradient colored
text in your pgfpicture environment, you can achieve an
approximate effect by doing the following:
Note that the colors you see on the
screen may not exactly match colors produced by your printer
due to the non-invertible mapping between color spaces.
The colors 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 color
buttons.
