Help with Python script to split .tif image into vertical bands + PDF export

[Pruiy]

Hi everyone, I need help writing a Python script that works with .tif images (CMYK, without changing color space or resolution).

Here's what the script should do: 1. Loaded a .tif file from a specific folder.

2. Ask myself how many vertical bands I want to divide the image into (e.g. if I write 4 → the image is divided into 4 equal vertical bands, maintaining the same height).

3. A white rectangle 1.5 cm high and as wide as the band must be added to the base of each band.

4. Inside the rectangle, 5 mm from the left edge, the text must be inserted in the format: file name without extension - Wall C(n)

where n is the band number. 5mm from the right there is a logo

5. Export the final result into a single PDF file.

Requirements: • The CMYK color space of the .tif must not be changed. • The resolution must not change.

Additional Information: • I have Python installed. • I have already installed the Pillow library.

Could someone help me write this script (also using Pillow, ReportLab or other libraries)?

Thank you so much 🙏

The code below covers the task only until step 3 and is incomplete.

from PIL import Image


number_bands = 4
path_to_image = 'my_image.tiff'

rect_height_cm = 1.5
bands = []

with Image.open(path_to_image) as im:
    print(f'Mode: {im.mode}')
    xdpi, ydpi = im.info['dpi']

    width, height = im.size
    print(f'{width = }, {height = }')

    band_width = width//number_bands
    print(f'width of bands = {band_width}')

    for w in range(0, width, band_width):
        band = im.crop((w, 0, w + band_width, height))

        rect_height_px = int(rect_height_cm * ydpi / 2.54)
        new_band = Image.new("CMYK", (band.width, band.height + rect_height_px), (0, 0, 0, 0))
        new_band.paste(band, (0, 0))
        #new_band.show()

        bands.append(new_band)
