Some image colors is changed after extraction

[omvishwas]

I am using this code for the extraction of the images from PDF, It's working fine on some images but for some images it's changing the colors of the image. Like for example I have a images which have Orange color in PDF ,But after extraction color is changed into pink.

So can you please suggest me how I can overcome this?

This is the code I am using for image extraction.

`import pdfminer from pdfminer.image import ImageWriter from pdfminer.high_level import extract_pages

pages = list(extract_pages('Socument.pdf')) page = pages[0]

def get_image(layout_object): if isinstance(layout_object, pdfminer.layout.LTImage): return layout_object if isinstance(layout_object, pdfminer.layout.LTContainer): for child in layout_object: return get_image(child) else: return None

def save_images_from_page(page: pdfminer.layout.LTPage): images = list(filter(bool, map(get_image, page))) iw = ImageWriter('image') for image in images: iw.export_image(image)

save_images_from_page(page) `

I also had the same problem. Some images after extraction have bmp extensions that change color or become unreadable This is my code

import pdfminer
from pdfminer.image import ImageWriter
from pdfminer.high_level import extract_pages

def get_image(layout_object):
    # recursively locate Image objects in page_layout
    if isinstance(layout_object, pdfminer.layout.LTImage):
        return [layout_object]
    if isinstance(layout_object, pdfminer.layout.LTContainer):
        img_list = []
        for child in layout_object:
            img_list = img_list + get_image(child)
        return img_list
    else:
        return []

def extract_pdf_img(pdf_filepath):
    iw = ImageWriter('output_dir')
    for page_layout in extract_pages(pdf_filepath):
        image_list = get_image(page_layout)
        if len(image_list):
            for image in image_list:
                iw.export_image(image)

if __name__ == "__main__":
    pdf_filepath = "sample.pdf"
    extract_pdf_img(pdf_filepath)

@omvishwas @khuongdvan Can either of you share the pdf? Otherwise we cannot debug.
