Too many arguments error when converting .tiff to .bmp

11 views (last 30 days)
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.

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

Try this:
t = Tiff('ref.tiff','r');
imageData = read(t);

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.
Error in imwrite (line 472) feval(fmt_s.write, data, map, filename, paramPairs{:});
