question: makes the given area of the image transparent if it was previously completely opaque used to remove the outer layer of a skin around the head if it was saved all opaque ; this would be redundant so it 's assumed that the skin maker is just using an image editor without an alpha channel concode_field_sep int imageWidth concode_elem_sep int[] imageData concode_elem_sep String __OBFID concode_elem_sep int imageHeight concode_field_sep boolean hasTransparency concode_elem_sep BufferedImage parseUserSkin concode_elem_sep void setAreaOpaque
