gimpgradients 3 LIBGIMP Library gimpgradientsOperations related to gradients. gboolean gimp_gradients_refresh (void); gchar** gimp_gradients_get_list (const gchar *filter, gint *num_gradients); gchar* gimp_gradients_get_gradient (void); gboolean gimp_gradients_set_gradient (const gchar *name); gdouble* gimp_gradients_sample_uniform (gint num_samples, gboolean reverse); gdouble* gimp_gradients_sample_custom (gint num_samples, const gdouble *positions, gboolean reverse); gchar* gimp_gradients_get_gradient_data (const gchar *name, gint sample_size, gboolean reverse, gint *width, gdouble **grad_data); Operations related to gradients. gimp_gradients_refreshgboolean gimp_gradients_refresh (void); Refresh current gradients. This function always succeeds. This procedure retrieves all gradients currently in the user's gradient path and updates the gradient dialogs accordingly. Returns : TRUE on success. gimp_gradients_get_listgchar** gimp_gradients_get_list (const gchar *filter, gint *num_gradients); Retrieve the list of loaded gradients. This procedure returns a list of the gradients that are currently loaded. You can later use the 'gimp_context_set_gradient' function to set the active gradient. filter : An optional regular expression used to filter the list. num_gradients : The number of loaded gradients. Returns : The list of gradient names. gimp_gradients_get_gradientgchar* gimp_gradients_get_gradient (void); gimp_gradients_get_gradient is deprecated and should not be used in newly-written code. This procedure is deprecated! Use gimp_context_get_gradient() instead. Returns : The name of the active gradient. gimp_gradients_set_gradientgboolean gimp_gradients_set_gradient (const gchar *name); gimp_gradients_set_gradient is deprecated and should not be used in newly-written code. This procedure is deprecated! Use gimp_context_set_gradient() instead. name : The name of the gradient to set. Returns : TRUE on success. gimp_gradients_sample_uniformgdouble* gimp_gradients_sample_uniform (gint num_samples, gboolean reverse); gimp_gradients_sample_uniform is deprecated and should not be used in newly-written code. This procedure is deprecated! Use gimp_gradient_get_uniform_samples() instead. num_samples : The number of samples to take. reverse : Use the reverse gradient. Returns : Color samples: { R1, G1, B1, A1, ..., Rn, Gn, Bn, An }. gimp_gradients_sample_customgdouble* gimp_gradients_sample_custom (gint num_samples, const gdouble *positions, gboolean reverse); gimp_gradients_sample_custom is deprecated and should not be used in newly-written code. This procedure is deprecated! Use gimp_gradient_get_custom_samples() instead. num_samples : The number of samples to take. positions : The list of positions to sample along the gradient. reverse : Use the reverse gradient. Returns : Color samples: { R1, G1, B1, A1, ..., Rn, Gn, Bn, An }. gimp_gradients_get_gradient_datagchar* gimp_gradients_get_gradient_data (const gchar *name, gint sample_size, gboolean reverse, gint *width, gdouble **grad_data); gimp_gradients_get_gradient_data is deprecated and should not be used in newly-written code. This procedure is deprecated! Use gimp_gradient_get_uniform_samples() instead. name : The gradient name (\"\" means current active gradient). sample_size : Size of the sample to return when the gradient is changed. reverse : Use the reverse gradient. width : The gradient sample width (r,g,b,a). grad_data : The gradient sample data. Returns : The gradient name.
