resize2dx

Arguments:

Description:

Resize selected images along the x-axis, 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:

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