### images modules
#import pygame # designed for writing games. (is not specific to images)

#import scipy # deprecating image I/O functionality and will be removed
### Pillow was the main library used by Scipy for images.

#import imageio # variety of plugins for many images formats.
### Pillow is also the main plugin of imageio for common images

### PIL (Python Image Library) been late adapted on Python3
### then a fork for Python 3 named Pillow been made
### so Pillow and PIL are almost the same
from PIL import Image
from PIL import ImageChops
from PIL import ImageDraw
from PIL import ImageFont
from PIL import ImageOps

### OpenCV (OpenSource Computer Vision) is available in Debian repo
### But no official OpenCV packages released by OpenCV.org on PyPI
### But on PyPI the not official opencv-contrib-python includes all OpenCV functionality.

### PIL Image modes:
BITMAP_MODE = '1' #1b this binary mode is not respected, pixels values are stored with 0 or 255.
GREY_MODE = 'L' #1o shade of grey varies from 0 to 256
LA_MODE = 'LA' # same as L mode with alpha
INDEX_MODE = 'P' #1o the number of colors in a palette may vary, it is not always 256 colors,
RGB_MODE = 'RGB' #3o true color
HSV_MODE = 'HSV'	#3o Hue, Saturation, Value
RGBA_MODE = 'RGBA' #4o true color with transparency
INT_MODE = 'I' #4o(signed integer) why signed ?? anyway, I did not find any image format with this mode
FLOAT_MODE = 'F' #4o(floating point) I did not find any image format with this mode.

### resize resample:
### If omitted, or if the image has mode “1” or “P”, it is set PIL.Image.NEAREST.
NEAREST=Image.NEAREST# (use nearest pixels neighbour)
BILINEAR=Image.BILINEAR# (linear pixels interpolation)
BICUBIC=Image.BICUBIC# (cubic spline pixels interpolation) **the most interesting***

(is not specific to images) #import scipy # deprecating image I/O functionality and will be removed ### Pillow was the main library used by Scipy for images. #import imageio # variety of plugins for many images formats. ### Pillow is also the main plugin of imageio for common images ### PIL (Python Image Library) been late adapted on Python3 ### then a fork for Python 3 named Pillow been made ### so Pillow and PIL are almost the same ### OpenCV (OpenSource Computer Vision) is available in Debian repo ### But no official OpenCV packages released by OpenCV.org on PyPI ### But on PyPI the not official opencv-contrib-python includes all OpenCV functionality. #import cairo # 2D graphics library ### others required modules # use for exporting image as array ### PIL Image modes: #1b this binary mode is not respected, pixels values are stored with 0 or 255. #1o shade of grey varies from 0 to 256 # same as L mode with alpha #1o the number of colors in a palette may vary, it is not always 256 colors, #3o true color #3o Hue, Saturation, Value #4o true color with transparency #4o(signed integer) why signed ?? anyway, I did not find any image format with this mode #4o(floating point) I did not find any image format with this mode. ### resize resample: ### If omitted, or if the image has mode “1” or “P”, it is set PIL.Image.NEAREST. # (use nearest pixels neighbour) # (linear pixels interpolation) # (cubic spline pixels interpolation) **the most interesting*** # (a high-quality downsampling pixels filter) ### transpose methods: ### text alignement ### Direction of the text. ### not supported without libraqm # (right to left) # (left to right) # (top to bottom). Requires libraqm. ### pixel location Indexes ### pixel compo Indexes ### RGB basics colors ### disable DecompressionBomb safety #Image.MAX_IMAGE_PIXELS = 200000**2 #Image.warnings.simplefilter('ignore', Image.DecompressionBombWarning) Load and image file and show it in window #display the window infinitely until any keypress. allow bitmap image manipulation mode is the format of pixels, size contains x and y image dimension, color concern the image background #self.filename= self.img.filename #self.size= self.img.size #self.fmt = self.img.format #self.mode = self.img.mode #self.info = self.img.info get extra info about the image get the x,y size of the image get image pixel format info return the quantity of pixels for each colors display the image in new window get the valu of image pixel change the valu of image pixel change the transparency of the image resize the image by x,y new size rotate flip the image 		FLIP_VERTICALLY adapt image for openGL 		ROTATE_270 FLIP_VERTICALLY adapt image for numpy array displace the image by x,y pixel move cut the image by left,top,right,bottom convert image into the given mode # ImageOps.grayscale(self.img) = self.img.convert('L') # image.convert(mode='F') # transforms the image values into float, but without putting them between 0.0 and 1.0 save image in default format save image in .gif format save image in .bmp format save image in .tga format save image in .tif format save image in .png format #scale mini is (1,1) repeat the image horizontally and vertically # create a new  image #print(self.img.size,scale) #print(left, top) return image data as opengl image # tostring() has been removed.
