IndexBitmap ImagesVector ImagesTypes of Bitmap and Vector ImagesBitmap ImagesBitmap images are made up of pixels placed in vertical and horizontal rows to form a grid. They are little squares of the same size of individual color and brightness and they come together and make up what you see on the screen. Most computer monitors display around 70-100 pixels per inch, depending on the device used and settings, while smartphones can display up to 3 times more pixels than your computer. Pixels are image elements and their color will not change even if you enlarge and enlarge the pixels. Even the rounded shapes are made up of tiny boxes and create the illusion of a curved line.

When the image is enlarged you can clearly see each individual square dot of color. The white background of bitmap images is made up of individual pixels even if they appear to be a single solid color. Bitmap images are resolution-dependent, a measurement of the output quality of an image, usually in terms of patches, pixels, dots, or lines per inch. Resolution is usually referred to as dpi (dots per inch) or psi (pixels per inch). The terminology varies depending on the intended output device. Bitmap images displayed on computer screens at screen resolution are approximately 100 ppi. The most common bitmap formats include GIF, JPEG, JPG, PNG, TIFF, and PSD. Vector images Vector images are made up of Bezier curves, which are individual scalable objects defined by mathematical equations. The renderings are always of the highest quality because they are device independent. Objects can consist of lines, curves, and shapes with editable attributes such as color, fill, and outline, and the quality of the object will not be affected if you change its attributes. You can easily change any number of object attributes, without destroying the base object. It can also be modified by shaping and transforming it using nodes and control handles. Because they are scalable images, you can increase and decrease the size of vector images to any extent, and your lines will not be destroyed or blurred both on screen and in print. Characters are a type of vector object. Vector images are usually made up of solid areas of color or gradients, but they cannot represent the subtle tones of a photograph, which is why most vector images have a cartoon-like appearance. They are becoming more and more advanced, today's vector tools allow you to apply bitmap textures to objects giving them a photorealistic look. You can now also create smooth blends, transparencies, and shadows that were always difficult to achieve in vector drawing programs. The most common vector formats include AI, CDR, CMX, SVG, CGM, DXF, and WMF. Please note: this is just an example. Get a customized paper from our expert writers now. Get a Custom EssayBitmap vs Vector Image TypesThe advantage of vector images is that they are not limited to rectangular shapes like bitmaps and can be placed on top of other objects with the underlying object visible. The disadvantage of vector images is that they are not suitable for creating photorealistic imagery and that one is needed.
