Syntax

[xLimitsOut,yLimitsOut] = outputLimits(tform,xLimitsIn,yLimitsIn)
[xLimitsOut,yLimitsOut,zLimitsOut] = outputLimits(tform,xLimitsIn,yLimitsIn,zLimitsIn)

Description

example

[xLimitsOut,yLimitsOut] = outputLimits(tform,xLimitsIn,yLimitsIn)estimates the output spatial limits corresponding to a set of input spatial limits,xLimitsInandyLimitsIn, given 2-D geometric transformationtform.

example

[xLimitsOut,yLimitsOut,zLimitsOut] = outputLimits(tform,xLimitsIn,yLimitsIn,zLimitsIn)estimates the output spatial limits, given 3-D geometric transformationtform.

Examples

Create anaffine2dobject that defines a rotation of 10 degrees counter-clockwise.

theta = 10; tform = affine2d([cosd(theta) -sind(theta) 0; sind(theta) cosd(theta) 0; 0 0 1]);
tform = affine2d with properties: T: [3x3 double] Dimensionality: 2

Estimate the output spatial limits, given the geometric transformation.

[xlim, ylim] = outputLimits(tform,[1 240],[1 291])
xlim = 1.1585 286.8855 ylim = -40.6908 286.4054

Create anaffine3dobject that defines a different scale factor in each dimension.

Sx = 1.2; Sy = 1.6; Sz = 2.4; tform = affine3d([Sx 0 0 0; 0 Sy 0 0; 0 0 Sz 0; 0 0 0 1]);
tform = affine3d with properties: T: [4x4 double] Dimensionality: 3

Estimate the output spatial limits, given the geometric transformation.

[xlim, ylim, zlim] = outputLimits(tform,[1 128],[1 128],[1 27])
xlim = 1.2000 153.6000 ylim = 1.6000 204.8000 zlim = 2.4000 64.8000
