1. They are generally not suitable for cursed photos or videos taken in the "real world" (for example - photographs of nature), although some formats support a mixed composition. Virtually all digital cameras store images in bitmap.
2. The data used to describe them must be processed by a powerful machine, i.e. the computer must be powerful enough to perform the necessary calculations for forming the final image. If the data volume is high it may slow down the rendering of the image on screen, even when working with small files.
3. Another disadvantage is that, even small drawing errors are often visible, when the images are enlarged to certain extent. Such an incident can affect the quality of the images, especially when they are used in the field of animation.
Despite the fact that vector images have a few disadvantages, they have a wide range of applications and are implemented in the fields of computer graphics, architecture and engineering etc.
