Raster images are stored in pixels. Vector images are stored as shapes. All sorts of editing operations can be conducted on Vector images with ease. This makes it important to stored web images in Vector form rather than Raster form.
In order to understand why web images need to be converted from the raster to the vector format the two types of formats must be known. It is also important to know what are the pros and cons of storing images in each of the format. Images that are stored in the raster format stores images in the form of pixels. Raster format images can be edited with the help of a bitmap editor. If a Raster image has to be edited then a change has to be made to all the pixels that comprise the image. It is a mammoth and tedious task. Vector images are those images, which are stored in the form of shapes. This format is easier to handle and enables the functionality of shaping, sizing, orienting and moving an image with much aplomb.
Raster images impact the quality of an image whenever exposed to an edit action. If the size of a Raster image is increased the image becomes blurred and lacks sufficient quality to be considered a good image. In contrast, edit operations done on a vector image are much simpler to handle. This relative ease in handling vector images makes it more significant than raster images. It is for this very same reason that web images need a raster to vector conversion. Web images, which need to be in 3D, can be done only when the image is in Vector form. Other actions such as rotation or mirror image creation can only occur when the images are present in a Vector format. This makes the Vector format the best choice to store the web images.
Photo editors contain raster to vector conversion tools, which enable the transition of a web image from a raster to a vector image. The application of these tools makes the web images easy to be handled and can be subjected to various editing designs. A vector image can be stretched without creating any loss of resolution. This is not the case with raster images. Web images find important uses. It is for this reason that people want them to be stored in a format, which is hassle free if the images are subjected to any form of editing to suit a particular purpose. Storing in vector format gives the freedom to edit without investing any time in adjusting pixels.
If one were to perform a simple zoom operation on an image, which is stored in a raster format then there would be a potential loss of clarity and the image becomes blurry. This poor quality makes the raster format of storage a weal option to store web images. Images can be easily zoomed in or zoomed out if they are stored in a vector format, which makes them a suitable choice to store the web images. This humongous difference in the handling of the raster format and vector format makes the raster to vector conversion of web images a primary choice. This objective can be achieved with the help of conversion tools available in photo editing software.
