Bitmap graphics, or raster images, are composed of pixels, each with a specific color, resembling a mosaic. They are ideal for detailed, color-rich visuals such as digital photographs and complex illustrations. This text delves into color models like RGB and CMYK, bit depth, file formats like JPEG, PNG, GIF, and BMP, and their applications in digital media. While bitmap graphics offer high detail and color range, they face issues with scaling and file size.

Bitmap graphics consist of a grid of pixels that can be assigned specific colors
Mosaic
Bitmap images are similar to mosaics, where small pieces come together to form a complete picture
Bitmap graphics excel at depicting intricate visuals, but resizing can result in a loss of clarity and they have larger file sizes compared to vector graphics
Bitmap graphics use the RGB model to combine red, green, and blue light to produce a spectrum of colors
The CMYK model is used for print media and combines cyan, magenta, yellow, and key (black) to define colors
Bit depth determines the number of bits used to represent the color of each pixel, with higher bit depths allowing for a broader range of colors
JPEG is commonly used for photographs due to its efficient compression algorithms
PNG is favored for its lossless compression and support for transparency, making it ideal for web graphics
GIF is limited to 256 colors and is commonly used for simple images and animations
BMP is less favored for web use due to its lack of compression, resulting in larger file sizes
Bitmap graphics are used in digital photography to capture color data and produce high-resolution images
PNG is often used for web graphics such as logos and banners due to its clear background capabilities
Bitmap graphics are essential for rendering all visual elements in video games
Bitmap graphics allow for precise manipulation of color and detail at the pixel level, making them popular among digital artists

Pixel Definition in Bitmap Graphics
A pixel is the smallest unit in a bitmap image, representing a single point of color.

Resizing Bitmap Images Consequences
Altering bitmap size can degrade image quality, causing blurriness or pixelation.
02
Bitmap vs. Vector File Size
Bitmaps often have larger file sizes than vectors due to detailed color information for each pixel.
