Tiff library to export Tiff image uint32

I don't know how exactly to use the tifflib code given by matlab. I have a uint32 image J on matlab and i want to export it in tiff. can anyone tell me how?

Have a read here and here. Explain what you have tried so far. Show the code.

Have you read the documentation for write?

[Mirett Boliard]

this is the image that i have on matlab:

J= imopen(I,SE);

this is the code i used

t = Tiff(filename, 'w'); 
tagstruct.ImageLength = size(A, 1); 
tagstruct.ImageWidth = size(A, 2); 
tagstruct.Compression = Tiff.Compression.None; 
tagstruct.SampleFormat = Tiff.SampleFormat.IEEEFP; 
tagstruct.Photometric = Tiff.Photometric.MinIsBlack; 
tagstruct.BitsPerSample = 32; 
tagstruct.SamplesPerPixel = 1; 
tagstruct.PlanarConfiguration = Tiff.PlanarConfiguration.Chunky;
t.setTag(tagstruct); 
t.write(A); 
t.close();

tagstruct.SampleFormat = Tiff.SampleFormat.Uint;

can anyone help please

Why the impatience? It has only been 20 minutes since you posted the question. People in Europe are probably sleeping or going to sleep, and the US/Canada are still in office hours. For most contributors this is something for their spare time. If you need answers this fast, consider hiring a consultant.

Also, this is not answer. Please only post an answer if you actually solve the question you posed.

I generated an example with the line below

A=uint32(randi(uint32(inf),255,255));

Then, running your code resulted in this error:

If SampleFormat is IEEEFP, the image datatype is restricted
to one of the following:  single, double.

So your choice of format is incompatible with your choice of input data type. There are two ways to fix this:

1. Set tagstruct.SampleFormat = Tiff.SampleFormat.Uint;
2. Cast your data to the single datatype with A=single(A);.
