What Are Bitmap Graphics? (Why Images Become Blurry When You Zoom In!)

Have you ever wondered why some images become blurry or pixelated when you zoom in? In this video, we'll explore Bitmap Graphics (also known as Raster Graphics) and learn how they are created using thousands—or even millions—of tiny colored squares called pixels. We'll also explain how resolution, pixels per inch (PPI), and image quality affect the appearance of digital images. Using simple explanations and real-life examples, you'll understand why bitmap graphics are widely used for photographs and why increasing their size can reduce image quality. 📚 In this lesson, you'll learn: ✅ What bitmap graphics are ✅ How bitmap images are made from pixels ✅ What resolution means ✅ What Pixels Per Inch (PPI) is ✅ How image quality changes when resizing a bitmap ✅ Common bitmap file formats (BMP, JPG, PNG, GIF, TIFF) ✅ Advantages and disadvantages of bitmap graphics ✅ Bitmap vs Vector Graphics explained This lesson is perfect for ICT students, Computer Science learners, Graphic Design beginners, GCSE, IGCSE, Cambridge, and Pearson Edexcel students preparing for exams or learning digital graphics. 👍 If you enjoyed this lesson, don't forget to Like the video. 💬 Have questions?
