resize2dx

Arguments:

Description:

Resize selected images along the x-axis, while preserving 2D ratio.

(equivalent to shortcut command r2dx).


interpolation can be { -1:none (memory content) | 0:none | 1:nearest | 2:average | 3:linear | 4:grid | 5:bicubic | 6:lanczos }.
boundary_conditions has different meanings, according to the chosen interpolation mode :
. When 'interpolation=={ -1 | 1 | 2 | 4 }', boundary_conditions is meaningless.
. When interpolation==0, boundary_conditions can be { 0:dirichlet | 1:neumann | 2:periodic | 3:mirror }.
. When 'interpolation=={ 3 | 5 | 6 }', boundary_conditions can be { 0:none | 1:neumann }.
ax,ay,az,ac set the centering along each axis when interpolation=0
(set to 0 by default, must be defined in range [0,1]).

Default values:

interpolation=3, boundary_conditions=0 and ax=ay=az=ac=0.

Example of use:

image.jpg +resize2dx 100,2 append x

Command: image.jpg +resize2dx 100,2 append x
