| | As can be seen here,in this step, the final result take only small part of the source image. |
| | |
| | It is quite difficult to trace back what the source image look like but it is the preparation for the next step. |

| I also made the gif version of Kaleidoscope by make 35 different images each turning 10 degree of the source image.

|
| Source image : illustration from Oliver Jeffers
| | '''STEP 2 : moving Kaleido''' |
| [[File:JEFFERS>JPG]]
| |
|
| |
|
| This is the code of Gif Version
| | The next step is to make the bot gives more feeling of Kaleidoscope. The nice part of Kaleidoscope is whhen one rotate it around and see the abtract patterns moving. |
|
| |
|
| [[Media:jeffers.gif |Example result .GIF]]
| | I try to make it the similar feeling here with the bot that each still image is so abstact but when one finish watching the whole loop of rotation then you will have clue about what is the source image. |

| |
|
| |
|
| from PIL import Image, ImageDraw,ImageFilter
| | In the code, I made the variable 'n' and 'a' to be able to adjust the the result GIF file. |
| import PIL.ImageOps as im
| | n is the number of the rotation time |
| import numpy as np
| | a is the degree of the rotation |
| import moviepy.editor as mpy
| |
|
| |
|
| | so they will affect how smooth the animated GIF going to be. |

| |
|
| # add style to pattern
| | Last step . . . for the summaery event , I improved a bit the quality of the |

| | GIF by editing the code to be able to make best quality it can and also the final GIF is not larger that the twitter status update limit. |
| #pattern= pattern_plain.filter(ImageFilter.EDGE_ENHANCE)
| |
| pattern.save('pattern_tri.png')
| |
| print('....stylized pattern....')
| |
| | |
|
| |
|
| #make square canvas for the output (wide = double size of height of primary pattern)
| | So I added lines of code to get the size of the final GIF and resize it if it exceed the limit. |
| canvas =Image.new('RGBA',(2*trih,2*trih), (255,255,255,0))
