python - How do I save 100 binary images into a single file? -

so if have 100 binary images type .bmp wondering if there library can use save single file later read in file , iterate through each image in python.

if there no library planning on reading of 100 binary images save them array in python save array file 100_images.format.

i wondering in format can save file make small possible? since images binary 32 32 pixels how can efficiently?

i thinking save 100 images array so:

array index 0             0 or 1 if image 1 pixel @ (0, 0) white(0) or black(1) 1             0 or 1 if image 1 pixel @ (0, 1) white(0) or black(1) ... 1023          0 or 1 if image 1 pixel @ (31, 31) white(0) or black(1) 1024          0 or 1 if image 2 pixel @ (0, 0) white(0) or black(1) ... 

then write file in python. don't know type of file should make it. in code reads through 100 binary images want work like:

binary_images_manager = new binaryimagesmanager('100_images.format')  in range(number_of_images_to_see):     int[][] binary_image = binary_images_manager.readimage(i) 

i run length encoding: https://en.wikipedia.org/wiki/run-length_encoding

you can use 1 of implementation python: https://www.rosettacode.org/wiki/run-length_encoding#python

encoding:

1. for each image matrix flatten using np.flatten
2. run length encode image
3. add code list
4. after images encoded pickle list

decoding:

1. unpickle list
2. for each item in list decode run length code
3. reshape resulted vector desired matrix shape
