|
||||
|
||||
### Selected Judges Remarks:
|
||||
|
||||
The file `small.jpg` will be approximately of the same size as the raw image data
|
||||
in the program. Compare the level of the detail and the artifacts of
|
||||
`small.jpg` and `lena.ppm`.
|
||||
|
||||
### Selected Judges Remarks:
|
||||
|
||||
Compressing images is just a matter of simple arithmetic and some magic, isn't it?
|
||||
|
||||
We could understand some of the arithmetic but none of the magic.
|
||||
|
||||
Deciphering the mechanism used for data encoding to make use
|
||||
of the whitespaces, braces and semicolons should be a slightly easier task.

|

|

## Author's comments:
|
||||
|
||||
This program outputs a 128x128 RGB image file to the standard output
|
||||
using the portable pixmap file format (PPM). It contains the famous
|
||||
"Lena" image which is used in many image compression tests.
