Declaration [src]
gboolean
gimp_gradient_get_custom_samples (
GimpGradient* gradient,
gint num_samples,
const gdouble* positions,
gboolean reverse,
gint* num_color_samples,
gdouble** color_samples
)
Description [src]
Sample the gradient in custom positions.
Samples the color of the gradient at positions from a list. The left endpoint of the gradient corresponds to position 0.0, and the right endpoint corresponds to 1.0. Returns a list of floating-point values, four for each sample (RGBA.)
Available since: 2.2
Parameters
num_samples-
Type:
gintThe number of samples to take.
positions-
Type: An array of
doubleThe list of positions to sample along the gradient.
The length of the array is specified in the num_samplesargument.The data is owned by the caller of the function. reverse-
Type:
gbooleanUse the reverse gradient.
num_color_samples-
Type:
gint*Length of the color_samples array (4 * num_samples).
The argument will be set by the function. color_samples-
Type: An array of
doubleColor samples: { R1, G1, B1, A1, …, Rn, Gn, Bn, An }.
The argument will be set by the function. The length of the array is specified in the num_color_samplesargument.The instance takes ownership of the data, and is responsible for freeing it.
