# pixelator.py
See some images that used this at
Flickr.
```
usage: pixelator.py [-h] [-i INSPEC] [-o OUTFILE]
[-e {average,random,nowt,test,test2}] [-n [NORMALISE]]
[-k] [-b BATCH_SIZE] [-s]
```
Create a composite image either by averaging or selecting random pixels from input
images.
If images are not the same size, they can be normalised first, either to the mode, mean
or a specified size.
If there are many images to average, ImageMagick uses a lot of RAM causing very slow
paging. To counter this, average in (preferably equal-sized) batches, which creates temp
averages from a smaller number and then averages those.
```
optional arguments:
-h, --help show this help message and exit
-i INSPEC, --inspec INSPEC
Input file spec (default: *.jpg)
-o OUTFILE, --outfile OUTFILE
Output file name (default: out.jpg)
-e {average,random,nowt,test,test2}, --effect {average,random,nowt,test,test2}
Effect to apply (default: average)
-n [NORMALISE], --normalise [NORMALISE]
If images are different sizes, normalise them first.
[mode|mean|width,height] (default: None)
-k, --keep_normals Keep normalised images (default: False)
-b BATCH_SIZE, --batch-size BATCH_SIZE
For average: Batch size. For best results, should be a
factor of the total number. Use 'auto' to calculate
size. (default: None)
-s, --show For random: Show the output image (default: False)
```

# slitscan.py
See some images that used this at
Flickr.
```
usage: slitscan.py [-h] [-i INSPEC] [-o OUTFILE]
[-m {eiriksmagick,central,all}]
[-d {vertical,v,horizontal,h}] [-t THICKNESS] [-u]
[-c CACHE]
Slice input files into an output file. Requires PIL.
optional arguments:
-h, --help show this help message and exit
-i INSPEC, --inspec INSPEC
-v, --reverse Reverse list of input files (default: False)
Input file spec (default: *.jpg)
-o OUTFILE, --outfile OUTFILE
Output file name (default: None)
-m {eiriksmagick,central,all}, --mode {eiriksmagick,central,all}
How to slice images. 'central' takes just the middle
slices from each image, 'eiriksmagick' takes a
different slice from each, moving from left to right
(or top to bottom). Both create a single image. 'all'
makes lots of image, each with slices from the same
place. (default: eiriksmagick)
-d {vertical,v,horizontal,h}, --direction {vertical,v,horizontal,h}
Direction to slitify (default: vertical)
-t THICKNESS, --thickness THICKNESS
Slit thickness in pixels. Default is to calculate
based on number of input images. (default: None)
-u, --useallinput Use every input file even if more than the width or
height (default: False)
-c CACHE, --cache CACHE
Load this many images into memory, the rest will be
read on demand from disk (for: --mode all) (default:
None)
