For creating a bitmap image
some of the software’s that can be used are GIMP, Paint and Photoshop. PNG
Bitmap files are popular and keep more information than what a jpeg will, the
problem with this is it may give you a higher quality image but this means that
it is uncompressed and therefore a bigger file size, which will take up more space. Bitmap is for viewing images on a computer screen, and are accessible to anyone with a computer and/or internet. Bitmap can’t be scaled or else the image will become distorted and pixelated. Another good thing about bitmap images is that it’s really easy to convert them from one file type to another, for example, a Targa to Tiff or Jpeg and can be seen on any type of screen. A Jpeg is a compressed file which is easier to send over the internet and easier to store. Due to it being compressed the quality is lower as information is lost during compression. Bitmap tends to be used more for logos and general online and promotional use. These images are promotional images from the actual DreamWorks website.

Vector Graphics

Vector
Graphic Image,by

To create a vector graphic image, software such as Illustrator and Flash will be used. With vector graphic images, you can stretch the image as much as you want and the image will not become distorted or pixelated. Vector images are higher quality and tend to be used for visual artworks. Vector is generally used for printing as it is a high quality, uncompressed format. Vector graphics can be used online but has to be converted to a bitmap image, such as Jpeg or Tiff, so technically you can’t actually see a vector graphic on a screen usually without requiring a plug in. Vector Graphics tends to have a much more smother look than what bitmaps do and tends to be used for creating line art and logos. Vector Graphics are good because they can be easily altered then converted into a bitmap file. A problem with a Bitmap image requires alot of space, where as Vector Graphics is much smaller, which makes it easier to sore. Though Bitmap Images can be transferred easily, which is why vector graphics can be transferred into bitmaps.

Bitmap and Vector Comparison
This is a Bitmap image, it is a photo taken and altered most likely in Photoshop or gimp.It is aesthetically different to Vector graphic images as bitmap images tend to have a lot more detailed than what vector images usually have. It is a much larger file so it's harder to store.
This is a Vector Graphics Image, It looks very detailed but looking closer reveals it consists of very basic and un-detailed shapes. It is a much smaller file size which is good for wanting to store a large amount of images. Vector images are mainly used for things such as line and logo designs. Though it's aesthetically alot more simple than bitmaps it has it's own style and often a minamilistic look though this is not always the case.
Index Colour
Dithering
Dithering is to sort of create the appearance of blending and looking as if new shades of coloure in the image are their. Dithering is often used with programs and software's that lack a variety of colour.
Anti-Aliasing
Anti-Aliasing is an effect of blurring an images lines of colour together to create the illusion of a smoother and less jagged and pixelated look. It is often used for close ups of bitmap images so the image looks smoother than what it really is.
