Other:
No additional information is stored in the ImageMagick using +profile "*" in the deleted picture.
Jmagick, using the Profileimage ("*", null) method on the Magickimage class, deleting the picture does not store additional information.
Use-quality to control the quality of pictures in ImageMagick,
Jmagick, use the Setquality (80) method on the Imageinfo class to control the quality of the picture
