What are the characteristics of the following graphics file formats:

• 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? How can this be useful in your coursework project?

An 8-bit colour channel which is used to specify the transparency of each pixel in an image. An alpha channel works like a sophisticated stencil, and is the digital equivalent of a matte.

An alpha channel can help us in our coursework as it can make backgrounds to images which we dont want transparent which will make it easier to move selected parts of the image.

What does RGB have to do with graphics?

RGB stands for red, green, blue and is the color language of computers. RGB defines the colours of the picture by using contrast of each colour in each pixel.
So RGB will determine the color of your graphic.

What is the difference between a Bitmap and a Vector?

Digital images created by placing lines and shapes in a two-dimensional or three-dimensional space. Some animation images are created as vector files.

www.gslis.utexas.edu/~vlibrary/glossary/

An image format that only defines an image in terms of black and white. A bitmapped image is generally used to define line art because its elements can only be black and white, unlike a grayscale image. In general, a bitmapped image will require a higher resolution to render good quality line art (1000 dpi or higher).

a vector image can only be defined by lines and shaps in 2D or 3D, were the bitmap will define an image in terms of black and white

What is a Pixel?

A pixel is the smallest part of a digital image. Digital images are measured in pixels, i.e a image can be 260 x 340 pixels. The colour of a pixel is made by the contrast of the 3 colours in the pixel, red, blue and green.

Teaching Experience

For the next couple of weeks are class is preparing to undertake a teaching experience. following the bad results we have been given a topic and we must make a power point presentation on this. then i will present the powerpoint to the class and hope that they can learn from the powerpoint. i will also make a lesson plan from which i will show how i will take the class, this will prepare me for the teaching experience. i will also have to give the class a small homework which they will have to complete. i am looking forward to doing this experience.
