Too many arguments error when converting .tiff to .bmp

I am trying to convert .tiff image to .bmp using the code as below

A=imread('ref.tif'); B=imwrite(A,'ref.bmp');

However, it failed and show "too many arguments".

Any recommendation on solving this? Thank you.

@Vanessa Phung: did you read the imwrite documentation? Does that documentation show any output arguments for imwrite? Why do you have an output argument in your code?:

B=imwrite(A,'ref.bmp');

Thanks.

I tried for .bmp. The output figure is 'all-white'. However, it works with .png format. Thanks for the comment.

I don't think that imwrite returns an output. It should be used as

imwrite(A,map,filename)

It works for .png, but failed on .bmp

Try this:

t = Tiff('ref.tiff','r');
imageData = read(t);
imwrite(imageData,'ref.bmp');

I got some message : Warning: TIFF library warning - 'TIFFReadDirectory: Unknown field with tag 50495 (0xc53f) encountered.' Error using writebmp (line 14) Expected X to be one of these types:

logical, uint8, single, double

Instead its type was uint16.
