layer_resize width height quality function option param;

Resizes the layer. For the width and width, you can either provide absolute values or percentages; percentage values must be terminated with a “%” character without spaces, e.g “33.33%”.

You have the option of specifying the quality [blocky, normal, high, custom].

If the quality is “custom”, you must specify the function [nearest_neighbour, bilinear, bicubic_cardinal, bicubic_b_spline, bicubic_bc_spline, windowed_sinc]. If the function is “windowed_sinc”, you must specify the window type via option [bartlett, blackman, blackman_harris, bohman, cosine, gauss, hamming, hann, kaiser", lanczos, parzen, rectangular, welch] and the window size via param [1..1024].

Example:
layer_resize 1024 300% custom windowed_sinc lanczos 8;
