jpegpixi is short for "JPEG pixel interpolator". It is a command-line utility
which interpolates pixels in JFIF images (commonly referred to as "JPEG
images"). This is useful to correct images from a digital camera with CCD
defects.
.
jpegpixi tries to preserve the quality of the JFIF image as much as possible.
Most graphics programs decode JFIF images when they are loaded, and re-encode
them when they are saved, which results in an overall loss of quality.
jpegpixi, on the other hand, does not decode and re-encode the image, but
manipulates the encoded image data. In doing so, it also preserves EXIF
metadata. |
