Essay / Bitmaps and Vector Images
Table of Contents BitmapsVector ImagesBitmaps and Types of Vector ImagesBitmapsBitmaps are made up of pixels positioned in vertical and horizontal rows to form a grid. These are tiny squares of the same size, individual color and brightness, that come together and make up what you see on your screen. Most computer monitors display around 70 to 100 pixels per inch, depending on the device you're using and settings, while smartphones can display up to 3 times more pixels than your computer. Pixels are image elements and their color will not vary even if you enlarge and zoom in on the pixels. Even rounded shapes are made up of tiny boxes and give the illusion of a curved line.

Get an original essayTypical desktop icons at screen resolution are usually 32 x 32 pixels, which means there are 32 colored dots in each direction and when they are. combined, they form an image. When the image is enlarged, you can clearly see each colored square dot. 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, which is a measure of an image's output quality, usually in terms of samples, pixels, dots, or lines per inch. Resolution is usually stated in dpi (dots per inch) or psi (pixels per inch). Terminology varies depending on the intended output device. Bitmap images displayed on computer monitors at screen resolution are approximately 100 ppi. Common bitmap formats include GIF, JPEG, JPG, PNG, TIFF and PSD. Vector Images Vector images are made up of Bézier curves - individual, evolving objects defined by mathematical equations. They always output with the highest quality because they are device independent. Objects can consist of lines, curves and shapes with editable attributes such as color, fill and stroke and the quality of the object will not be affected if you change its attributes. You can easily modify 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. Since these are scalable images, you can increase and decrease the size of vector images to any degree and your lines will not be destroyed or blurred both on screen and in print. . Fonts are a type of vector object. Vector images typically consist of solid areas of color or gradients, but they cannot represent the subtle tones of a photograph. This is why most vector images have a cartoon-like appearance. They are more and more advanced, today's vector tools allow you to apply bitmap textures to objects giving them a photorealistic appearance. You're also now able to create soft blends, transparency, and shading that have historically been difficult to achieve in vector drawing programs. Common vector formats include AI, CDR, CMX, SVG, CGM, DXF and WMF. Keep in mind: this is just an example. Get a personalized article from our expert writers now.
