The size of the file that can be embedded is half the product of the width x height of the image.
・ "2: 1 [embedding depth 2]" =
Embed 1 byte of file information for each pixel of image color information.
Since the amount of information that can be embedded in the file is prioritized, the deterioration of the image from the beginning is large.
The size of the file that can be embedded is the product of the width of the image x the height.
◎ Automatically adjusts the image size according to the file size to be embedded
