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

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?

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

What code did you use to save?

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

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.

Answer 1

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

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

[Walter Roberson]

You need 'w8' not 'w'; https://www.mathworks.com/help/matlab/ref/tiff.html#d123e1453467

See the example in the blog I posted the link to

@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)

>> a(1,1,1)

ans =

uint16

imread can read bigtiff. imwrite cannot write bigtiff. The link above shows how to write bigtiff.
