It would be very useful if the script allowed me to reverse the process of splitting by joining the processed tiles back together.

Hi whiplashoo,

Joined image will lost alpha info (was 32 bits, becomes 24 bits after joining).

Works fine with split method: alpha info will be reserved correctly after splitting.

Thank you.

If you give the program an absolute path, you will end up with a bunch of images in your users folder

Is it normal that the sum of the file sizes of the generated tiles is larger than the file size of the original image by 2x ?

Is there a way to avoid that?

Thanks for the great work on this library

hi whiplashoo,

Great tool,
but it failed to join images if image name already contains underscore symbol _.

Thank you.

I have tested the code on terminal and the package works as expected and with given example. The only issue so far is that the same code doesn't work on jupyter notebook.

Dear author, thanks for the awesome tool

As title, your sorting function on the string level (line 114) is a bug, shown by the code does not work for more than 10 images (0, 1, 10, 11, ...)

Hi:) I need to slice my images accordingly to some kind of algorithm, so terminal usage is cumbersome.
Is there a way to do it similar to this pseudocode?

from split-image import Slicer

list_of_slices = Slicer('myimage.jpg', rows_num, col_num)

Anyway to batch process/split images? Saving splits to a different directory?

Maybe there is an easy way to do this already by piping filenames to "split-image"?

Thanks!

• Batch processing multiple images

• Set a custom output directory

Hello
I want to split an image and place the result in a Split directory.
My script

import cv2
from split_image import split_image

split_image("Eau1_gray.jpg",1,8, False, False, |'Split'])

cv2.waitKey(0)
cv2.destroyAllWindows()

do not work. Split is OK but in the current directory

this doesn't seem to support the image orientation (rotation?) tag in images, at least on windows

so for example, using canon camera, turning the camera to take a vertical image -- the image looks ok within windows and image apps, but when running split on it, the source image is obviously taken as landscape instead of portrait orientation and hence the resulting pieces don't match expectations
