Writing a Graphics Image
When you save an image using imwrite
, the default behavior is to automatically reduce the bit depth to uint8
. Many of the images used in MATLAB are 8-bit, and most graphics file format images do not require double-precision data. One exception to the MATLAB rule for saving the image data as uint8
is that PNG and TIFF images can be saved as uint16
. Because these two formats support 16-bit data, you can override the MATLAB default behavior by specifying uint16
as the data type for imwrite
. The following example shows writing a 16-bit PNG file using imwrite
.
