Here are some examples showing off the MGIF image manipulation functions.
Most of the files were prepared by Eero Tamminen (see manual).

These pictures should really be in an ST-Guide manual supplement, but
that's for a later release of MGIFv5.

Pictures/
  Original images for the examples below.
Logo/
  How to make you own MGIF logo:
  - text explanation
  - final GIF
  - POV script for nice effects
  - example output using the POV script
Functions/
  Examples of the functions:
  - Rotate (44 degrees)
  - Histogram equalization
  - Inversion (no offset)
  - Log scaling
  - Threshold (at 128)
  - Contrast expansion (from 128)
  - Brightening (by 16)
  - Darkening (by 16)
  - Blur (size 3) (Median didn't change the image noticebly)
  - Lmax (size 3)
  - Lmin (size 3)
  - Oil (7, 64) (first Lmax 3 as otherwise it became too dark)
  - Pixelize (size 5)
Convolut/
  Examples of some convolution matrix applications:
  - Dirs image contains examples of all the directions using Kirsch.
  - Directional matrixes (NE direction):
    - Shift difference
    - Gradient direction
    - Smoothing
    - Kirsch
    - Sobel
    - Line
  - Bias (64) with the Kirsch matrix.
  - Symmetrical matrixes:
    - Low pass 2
    - High pass 2
    - Laplace 2
Combine/
  A pair of image combination examples.
  - Intheart: Intel outside image (1/4) overlaid on a heart (3/4)
    with an addition of laplace 2.
  - Guardian: Combined images with Kirch added on different
    accuracies for larger and smoother emboss effect.
