Declaration [src]
gboolean
gimp_gradient_get_uniform_samples (
GimpGradient* gradient,
gint num_samples,
gboolean reverse,
gint* num_color_samples,
gdouble** color_samples
)
Description [src]
Sample the gradient in uniform parts.
Samples colors uniformly across the gradient. It returns a list of floating-point values which correspond to the RGBA values for each sample. The minimum number of samples to take is 2, in which case the returned colors will correspond to the { 0.0, 1.0 } positions in the gradient. For example, if the number of samples is 3, the procedure will return the colors at positions { 0.0, 0.5, 1.0 }.
Available since: 2.2
Parameters
num_samples-
Type:
gintThe number of samples to take.
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.
