I want to combine two images, with the following characteristics:

A: r,c = 51200,38497 uint16

B: r,c = 41505,38497 uint16

into

C: r,c = 92705,38497 uint16

The problem is that when I am trying to save it is not possible due to the following error:

Images must contain fewer than 2^32 - 1 bytes of data.

In addition, a strange thing is that if it is not possible to write C as a tif in 16bits why it is possible to read an image with the similar rows and collumns of C matrix?

Any ideas about the saving step?

What code did you use to save?

How do you know it is? What code did you use to read?

Imwrite and imread. I am trying now to follow Walter and Liu answers by setting correctly the tags in Geotiff.

yes，sir，may be use TIFF object，such as

t = Tiff('myfile.tif','w');
write(t,your_image_data);
close(t);

@Walter Roberson yes，sir，it is important on configure tiff writer，thanks

@zbingos may be use an example，such as

clc; clear all; close all;
% configure tiff
t = Tiff('myfile.tif','w8');
setTag(t,'ImageLength',10);
setTag(t,'ImageWidth',10);
setTag(t,'Photometric',Tiff.Photometric.RGB);
setTag(t,'PlanarConfiguration',Tiff.PlanarConfiguration.Chunky);
setTag(t,'BitsPerSample',16);
setTag(t,'SamplesPerPixel',3);
% make data
your_image_data = uint16(ones(10,10,3));
your_image_data(1,1,1:3) = 2^32 - 1;
% write data
write(t,your_image_data);
close(t);
% read and display
a = imread('myfile.tif');
a(1,1,1)
