Introduction
Raster graphics are pictures made up of tiny squares called pixels! 🟦🟥 Each pixel has a color, and when you put them together, they create an image. Think of mosaic art made from colorful tiles! These graphics are often used in digital photography and video games. The images can be small or large, but they always have a specific number of pixels. The more pixels there are in a picture, the clearer the image looks. Raster graphics are everywhere—like in cartoons, websites, and your favorite video games! 🎮

How Raster Graphics Work
Raster graphics work like a grid or a giant checkerboard! Each square (or pixel) is a tiny dot that has its own color. 🌈
When you look at a raster image from far away, your eyes blend the colors of these pixels together, making one smooth picture. Imagine if you painted a giant picture but only used dots! The size of the image comes from how many pixels it has. If an image is 800 pixels wide and 600 pixels tall, it has 480,000 pixels! The better the pixel quality, the better the picture! 📷

History Of Raster Graphics
Raster graphics started in the 1960s, when computers were just beginning to be invented! 💻
One of the first pictures made with these graphics was called "the computer-generated images." In 1972, a scientist named Ivan Sutherland created a program called Sketchpad that let people draw on computer screens. This was a big step! It showed how computers can create pictures with pixels. In the late 1980s, raster graphics became more popular because of home computers. Today, they are used for everything from cartoons to Instagram photos! 📸

Raster Vs. Vector Graphics
Raster and vector graphics are two different ways to make pictures! 🖼
️ Raster graphics use pixels (tiny squares), while vector graphics use lines and mathematical formulas. Think of a raster image like a puzzle made of many small pieces. If you zoom in too much, it can get blurry. 😵
On the other hand, vector images can be resized without losing quality, so they always look sharp! 🎯
Vector graphics are often used for logos and icons. Both types of graphics are important for different projects and should be used wisely!

Pixel Density And Resolution
Pixel density is how many pixels fit in a specific area of an image, usually measured in pixels per inch (PPI). 🖼
️ Higher pixel density means more details and sharper images. If you have a photo at 300 PPI, it means there are 300 pixels packed into each inch! 🟩🟧 In comparison, a lower pixel density picture may look blurry or pixelated when you zoom in. Resolution is the overall size of images, describing how many pixels wide and tall it is. Higher resolution means more detail, making images look fantastic on screens! ✨

Color Models In Raster Graphics
Colors in raster graphics are made using different models, with RGB as the most popular! 🌈
RGB stands for Red, Green, and Blue—these are the three main colors of light. By mixing these three colors in various amounts, you can create thousands of different colors! For example, mixing red and green makes yellow! 🎨
Another model is CMYK, which stands for Cyan, Magenta, Yellow, and Black. This is often used for printing images on paper. Different colors can be created by mixing these inks, providing the colors we see in books and magazines! 🖍

Image Formats For Raster Graphics
Raster graphics come in many file formats, like JPEG, PNG, and GIF! 🖥
️ JPEG files are best for photos because they keep file sizes small. 📸
But sometimes, they lose some quality. PNG files are great for images with transparent backgrounds, like stickers! 🎉
GIFs are fun because they can show animations! 🎞
️ Other formats include BMP and TIFF, which are often used in printing and professional photography. Each format has its uses, helping you choose the right one for your project! So, always pick wisely to get the best picture! 👍

Editing And Manipulating Raster Images
Editing raster images is super fun! 🖌
️ With editing software, you can change almost anything in a picture. Want to make the sky bluer? Just select that area, and change the color! Want to resize an image? It's as easy as clicking a button! 🔄
You can also crop parts of the image to focus on specific details. Another cool trick is using filters that can give images unique looks, like making them look like a painting! 🎭
That way, you can personalize your photos and digital art to express yourself!
