- 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.
