You need to: 1. Read a PDF presentation about Autoimmune Hemolytic Anemia (AIHA) using OCR/image analysis 2. Create a clean, professional PowerPoint presentation from its content ## Step 1: Extract PDF Content The PDF is at: /home/daytona/workspace/attachments/12a24fa4-df37-4b0f-9708-9a7acd37789e/Autoimmune_Hemolytic_Anemia_AIHA(1).pdf PNG images of all pages are already extracted to: /home/daytona/workspace/pdf_images/ (page-01.png through page-27.png) Use this Python script to extract text using pytesseract OCR: ```python import pytesseract from PIL import Image import os pages_dir = '/home/daytona/workspace/pdf_images/' all_text = {} for i in range(1, 28): fname = f'page-{i:02d}.png' fpath = os.path.join(pages_dir, fname) if os.path.exists(fpath): img = Image.open(fpath) text = pytesseract.image_to_string(img) all_text[i] = text print(f"--- PAGE {i} ---") print(text) print() ``` Save the extracted text to /home/daytona/workspace/aiha_content.txt ## Step 2: Create the PowerPoint After extracting content, create a professional PPTX using PptxGenJS at /home/daytona/workspace/AIHA_Presentation.pptx **Design Requirements:** - Color scheme: Deep navy/blue theme (NO RED anywhere - remove all red elements) - Background: White (#FFFFFF) - Title slide background: Dark navy (#1B3A6B) - Section headers: Navy (#1B3A6B) - Accent color: Teal/Steel blue (#2E86AB) - Text: Dark charcoal (#2C3E50) on white slides - Large fonts: Title = 40pt, Headings = 32pt, Body = 22pt minimum - Clean, professional medical presentation style **Slide Structure:** 1. **Title Slide** (dark navy background, white text): - Title: "Autoimmune Hemolytic Anemia (AIHA)" - Subtitle line 1: "Presented by" - Subtitle line 2: "Dr. Saher Neda Jafar" (Note: FIRST slide gets "Presented by Dr. Saher Neda Jafar" added) 2-onwards: **Content Slides** - Use the extracted content from the PDF. Keep the EXACT same words/content, just make it presentable: - Each major topic becomes a slide - Clean bullet points with large readable fonts - Section divider slides (dark navy) for major topic changes - Tables where content has table structure **PptxGenJS script template:** ```javascript const pptxgen = require("pptxgenjs"); const pres = new pptxgen(); pres.layout = 'LAYOUT_16x9'; const NAVY = '1B3A6B'; const WHITE = 'FFFFFF'; const TEAL = '2E86AB'; const CHARCOAL = '2C3E50'; const LIGHT_BG = 'F5F8FA'; // Title slide let slide = pres.addSlide(); slide.background = { color: NAVY }; slide.addText("Autoimmune Hemolytic Anemia", { x: 0.5, y: 1.2, w: 9, h: 1.2, fontSize: 42, bold: true, color: WHITE, align: 'center' }); slide.addText("(AIHA)", { x: 0.5, y: 2.3, w: 9, h: 0.7, fontSize: 32, color: TEAL, align: 'center' }); slide.addText("Presented by", { x: 0.5, y: 3.5, w: 9, h: 0.5, fontSize: 22, color: 'AECDE0', align: 'center' }); slide.addText("Dr. Saher Neda Jafar", { x: 0.5, y: 4.0, w: 9, h: 0.7, fontSize: 28, bold: true, color: WHITE, align: 'center' }); // Content slide function function addContentSlide(title, bullets) { let s = pres.addSlide(); s.background = { color: WHITE }; // Top accent bar s.addShape(pres.ShapeType.rect, { x: 0, y: 0, w: 10, h: 0.12, fill: { color: NAVY } }); // Title s.addText(title, { x: 0.4, y: 0.2, w: 9.2, h: 0.8, fontSize: 32, bold: true, color: NAVY }); // Divider line s.addShape(pres.ShapeType.line, { x: 0.4, y: 1.0, w: 9.2, h: 0, line: { color: TEAL, width: 2 } }); // Bullets let items = bullets.map((b, i) => ({ text: b, options: { bullet: true, breakLine: i < bullets.length - 1 } })); s.addText(items, { x: 0.4, y: 1.15, w: 9.2, h: 4.3, fontSize: 22, color: CHARCOAL, valign: 'top' }); return s; } // Section divider function function addSectionSlide(title) { let s = pres.addSlide(); s.background = { color: NAVY }; s.addText(title, { x: 0.5, y: 2.0, w: 9, h: 1.5, fontSize: 38, bold: true, color: WHITE, align: 'center' }); s.addShape(pres.ShapeType.rect, { x: 3, y: 3.5, w: 4, h: 0.06, fill: { color: TEAL } }); return s; } // ... add all content slides based on extracted PDF content ... pres.writeFile({ fileName: '/home/daytona/workspace/AIHA_Presentation.pptx' }); ``` ## Important Notes: - If pytesseract is not available, use: `pip install --user pytesseract` or try `pip3 install --user pytesseract` - If OCR fails, use your medical knowledge about AIHA to create comprehensive slides covering: Definition, Classification (Warm vs Cold), Pathophysiology, Clinical Features, Diagnosis (blood smear, DAT/Coombs test, labs), Treatment (steroids, rituximab, splenectomy, etc.), and Prognosis - The AIHA PDF appears to be a medical presentation - include ALL standard AIHA topics you can see from the images - Keep ALL original words/content - do NOT change the wording, only make it visually presentable - NO RED color anywhere in the presentation - Output file MUST be at: /home/daytona/workspace/AIHA_Presentation.pptx ## What to return: 1. The OCR-extracted text from the PDF (summarized by slide) 2. Confirmation that the PPTX was created at /home/daytona/workspace/AIHA_Presentation.pptx 3. List of all slides created with their titles
