plug_in_curve_bend (v1.1.17 (2000/02/16))

NAME

plug_in_curve_bend - Bends a layer using 2 spline-curves

SYNOPSIS

bent_layer = plug_in_curve_bend (run_mode,image,drawable,rotation,smoothing,antialias,work_on_copy,curve_type,argc_upper_point_x,upper_point_x,argc_upper_point_y,upper_point_y,argc_lower_point_x,lower_point_x,argc_lower_point_y,lower_point_y,argc_upper_val_y,upper_val_y,argc_lower_val_y,lower_val_y)

DESCRIPTION

This plug-in does bend the active layer If there is a current selection it is copied to floating selection and the curve_bend distortion is done on the floating selection. If work_on_copy parameter is TRUE, the curve_bend distortion is done on a copy of the active layer (or floating selection). The upper and lower edges are bent in shape of 2 spline curves. both (upper and lower) curves are determined by upto 17 points or by 256 Y-Values if curve_type == 1 (freehand mode) If rotation is not 0, the layer is rotated before and rotated back after the bend operation. This enables bending in other directions than vertical.bending usually changes the size of the handled layer.this plugin sets the offsets of the handled layer to keep its center at the same position
