You can modify an image with grip modes, adjust an image for contrast, clip the image with a rectangle or polygon, or use an image as a cutting edge for a trim. Raster images, like many other drawing objects, can be copied, moved, or clipped. Unlike raster graphics, vectors graphics are always crisp and clean. Raster graphics can typically be scaled down with no loss of quality, but enlarging a bitmap image causes it to look blocky and "pixelated." For this reason, vector graphics are often used for certain images, such as company logos, which need to be scaled to different sizes. A raster image references the pixels in a specific grid. Take a step back, and all those colored pixels form a clear image, just like a mosaic. These pixels, which each represent a single color, are fitted onto a grid (or a raster proper, which is where the name comes from). JPEGs, GIFs and PNGs are common raster image types. Los rásteres son fotografías aéreas digitales, imágenes de satélite, imágenes digitales o incluso mapas escaneados. Raster graphics, also known as bitmaps, store image data as fixed pixels. It can convert raster images like JPEGs, GIFs and PNGs to scalable vector graphics (EPS, SVG, AI and PDF).

The latest version of Raster Design can open all common image formats and can support all the formats that AutoCAD can handle. Autotracer is a free online image vectorizer. JPEG and GIF are the most common compressed image formats on the Web, but several other types of image compression are available. Raster images use many colored pixels or individual building blocks to form a complete image. The Raster Design toolset allows users to seamlessly use images be it scanned photos, drone snapshots, digital elevation models, or even satellite images within the AutoCAD program. Fortunately, there are several image compression algorithms that have been developed to help reduce these file sizes. The number defines the location, size, or color of the pixels.
A raster image is an image file format thats defined by a pixel with one or more numbers associated with it. Since raster graphics need to store so much information, large bitmaps require large file sizes. Raster may refer to any of the following.
For example, a 640 x 480 image requires information to be stored for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel digital camera) needs to store information for a whopping 6,291,456 pixels. The larger the image, the more disk space the image file will take up. They are made up of grid of pixels, commonly referred to as a bitmap. Pictures found on the Web and photos you import from your digital camera are raster graphics. Most images you see on your computer screen are raster graphics.
