Here is some images of the fort george site were we have to design a suitable replacement for the site!

What are the characteristics of the following image files.

Bitmap: An image format that only defines an image in terms of black and white.
GIF: Graphics Interchange Format, is a compressed graphic file normally used for images that do not require too many colors (maximum 256).
PNG: PNG is a graphics format specifically designed for use on the World Wide Web. PNG enable compression of images without any loss of quality, including high-resolution images.
JPEG: JPEG graphics are capable of reproducing a full range of color while still remaining small enough for Web use. Most of the photographs you see on the Web are JPEG format.
XCF:
PSD: the default proprietary file of Adobe Photoshop. It allows for Adobe Photoshop formatting, Layers, DropShadows, etc. and is compatible with a variety of Adobe software such as InDesign.
SVG: Scalable Vector Graphics is a vector graphics language written in XML. Using SVG, graphics can be coded directly into an XML document.

What is an alpha channel?

alpha compositing is the process of combining an image with a background to create the appearance of partial transparency. It is often useful to render image elements in separate passes, and then combine the resulting multiple 2D images into a single, final image in a process called compositing. For example, compositing is used extensively when combining computer rendered image elements with live footage.

what does "RGB" have to do with image files?

RBG or red blue green is the model in which these 3 colours are combined to reproduce other colours.

these 3 colours combined correctly along with brightness can reproduce any colour.

2) What is the difference between VECTOR and BITMAP graphics? Explain both terms

VECTOR: Vector graphics is the use of points, lines, curves and polygons. These are all based on mathmatical equations to represent images in computer graphics.

BITMAP: Bitmap is a type of memory organisation used to store image files. Now, along with Pixmap it commonly refers to the similar concept of a spatially mapped array of pixels.

the difference between the two is that one creates images based on a mathmatical equation using lines, curves etc, and Bitmap uses an array of pixels saved in a certain way to generate its image.

What is a pixel?

Pixel is short for picture element. it is essentially a dot which contains aa certain amount of red blue and green along with the amount of brightness that makes up an image.
