unable to extract images from a loop

[BivashChakraborty]

Hey Jorj!

I am an noob programmer trying to build my skills by doing small projects. So this one involves extracting a certain subquestion from an exam paper.

I am trying to extract a subquestion if the next subquestion exists on that page itself. For some reason, the function only returns the image of the last loop. If I break the first loop at the first iteration itself, then it gives me the image but that doesn't really solve my problem.

I'm pretty sure, I'm missing something very basic and would be very happy if you could help me.

Thank you.

The code is pasted below.

def get_subquestions(ques_dict):
total_pages = pdf.chapter_page_count(0)

for i in ques_dict:
    current_page = pdf.load_page(ques_dict[i][0])
    ques_coord = ques_dict[i][1]
    sub_ques_list = ["(a)", "(b)", "(c)", "(d)", "(e)", "(f)", "(g)", "(h)", "(i)", "(j)", "(k)"]
    
    for j in range(0,len(sub_ques_list)-1):
        print(ques_dict[i][0], j, j+1)
        ##check if both sub-questions are on the same page.
        if current_page.search_for(sub_ques_list[j])!=[] and current_page.search_for(sub_ques_list[j+1])!=[]:
            print("true")
            current_subq_coord = current_page.search_for(sub_ques_list[j])
            next_subq_coord = current_page.search_for(sub_ques_list[j+1])
            
            print(current_subq_coord)
            print(next_subq_coord)
            
            q_rect_x0, q_rect_y0, q_rect_x1, q_rect_y1 = ques_coord
            sbqa_rect_x0, sbqa_rect_y0, sbqa_rect_x1, sbqa_rect_y1 = current_subq_coord[0]
            sbqb_rect_x0, sbqb_rect_y0, sbqb_rect_x1, sbqb_rect_y1 = next_subq_coord[0]
            current_sbques_context_rect = (q_rect_x0 - 7, sbqa_rect_y0 - 3, sbqa_rect_x0 + 500, sbqb_rect_y0 - 3)
            
            mat = fitz.Matrix(2,2)
            clip = fitz.Rect(current_sbques_context_rect)                            
            pix = current_page.get_pixmap(matrix=mat, clip=clip)
            pix.writeImage("Sub-ques_"+sub_ques_list[j]+".jpg")

Never mind. I figured it out. Thank you
