Function Gradient.addColorStopRGB
Adds an opaque color
stop to a gradient pattern. The offset
specifies the location along the gradient's control vector.
For example, a LinearGradient
's control vector is from
(x0,y0) to (x1,y1) while a RadialGradient
's control vector is
from any point
on the start circle to the corresponding point
on the end circle.
The color
is specified in the same way as in context.setSourceRGB().
If two (or more) stops are specified with identical offset
values, they will be sorted according to the order in which the
stops are added, (stops added earlier will compare less than
stops added later). This can be useful for reliably making sharp
color
transitions instead of the typical blend.
Prototypes
void addColorStopRGB(
double offset,
RGB color
);
void addColorStopRGB(
double offset,
double red,
double green,
double blue
);
Parameters
Name | Description |
---|---|
offset | an offset in the range [0.0 .. 1.0] |
Note
If the pattern is not a gradient pattern, (eg. a linear or radial pattern), then the pattern will be put into an error status with a status of CAIRO_STATUS_PATTERN_TYPE_MISMATCH.
