Example Illustration

missing image of VLwarpgrid(siz,T,scal,cent,isgeo)

Syntax

[VL,XL,YL,ZL]=VLwarpgrid([siz,T,scal,cent,isgeo])

Input Parameter

`siz`:		image or image size [r c]
`T`:		Transformation matrix
`scal`:		scaling factor
`cent`:		if true; image is centred; default is false
`isgeo`:		if true color is height in z; default is false

Output Parameter

`VL`:		Vertex list
`XL`:		warp grid X
`YL`:		warp grid Y
`ZL`:		warp grid Z

Examples


I=imread('cameraman.tif');
VLwarpgrid(I,TofR(rot(pi/6,0,0)));
fname='/Users/lueth/Downloads/737_5284.tiff'; [A,R,cmap] = readgeoraster(filename);
A=imread(filename);
VLwarpgrid(A,'','','',true);
