Awh john, you think flattery will make me do the most work. As usual I draw the short straw, so im the graphic co-ordinator????
I’m expecting some insightful video now to go alongside some “block-rocking beats” !!

GIMP Error
Again, my re-attempted effort of installing GIMP for my composite images. And computers were supposed to make life easier.

Google Sketchup
Having previously used google skecthup to design my IPod and attempted structures i have learned vast amounts of uses for google sketchup
SketchUp makes it particularly easy to manipulate lines and planes. Draw a shape, highlight it with the Pull/Push tool, pull it up, and voilà: you have a three-dimensional object.Using these tools and principles, you can create anything however whilst trying to mimic my transport system I encountered several difficuilties in doing so. The design of the transport system has lead to increased difficuilty and im currently hoping to recieve some asistance.

GIMP
When trying to install GIMP for windows this error message is prompted and phrohibiting me from installing the program and designing my composite images. If anyone has any suggestions or recommendations that would be appreciated as i can't get the work done and Mr. Barr isn't going to be a happy chap.How to design tables in HTML
As many of the class have realised number 6 of Mr. Barrs questions requires the summary of photoshop, microsoft paint and GIMP into a table under various headings. Currently no wizard is provided and therfore must be designed using HTML.
To do so effectively when publishing the post flick between the tab at the top right hand corner of the text box where it reads" edit html & Compose" . Select "Edit HTML" and now you need to theory to do so.
http://www.w3schools.com/html/html_tables.asp is an effective website with in-depth explantion of how to do so but in particular visit...
this allows for on the spot trial and error and to subsequently preview your design. Having used this for mine i recommend it.
It is important to note that upon completion you will be prompted with an error...in order to publish your post as intended you will need to remove "< html >< body >" from the top of the coding and "< /body >< /html >" from the bottom

What are the characteristics of the following graphics file formats?
5) What are the characteristics of the following graphics file formats?
Bitmap: A pixel based image which is of low quality but are also easy to use and manipulate
GIF(Graphic Interchange Format): A form of computer image that moves as an animation, because it consists of frames, like a movie with no sound.
PNG(Portable Network Graphics): which is a bitmap image format that uses lossless data compression.
JPEG(Joint Photographic Experts Group): JPEG is a standardized image compression mechanism.
XCF: A GIMP image file format; It supports saving each layer, the current selection, channels, transparency, paths and guides
PSD(Particle Size Distribution): Image in layers supporting masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, clipping paths and doutone settings.
SVG(Scalable Vector Graphics): XML-based language used to describe 2D vector-based graphics. The graphics are defined using mathematical expressions, allowing them to scale flawlessly.

What is an alpha channel? How can this be useful in your coursework project?
4) What is an alpha channel?
In graphics, a portion of each pixel's data is reserved for transparency information. The alpha channel is really a mask; it specifies how the pixel's colors should be merged with another pixel when the two are overlaid, one on top of the other.
How can this be useful in your coursework project?
This is especially important for animation, where the background changes from one frame to the next. This may prove useful when we eventually incorporate all data togethre ina persentation and this will ineviatble enhance its apperance. (Rendering overlapping objects that include an alpha value is called alpha blending.)
Currently Alpha channels are useful because they allow us to incorporate two images together and succesfully design a realistic composite image. I have to use a program like GIMP or Photoshop in order to alter the transparency and design a composite image of our selected transport system within Derry, as if currently in use.

What does “RGB” have to do with graphic files?
3) What does “RGB” have to do with graphic files?
RGB is a colour model; where red-green-blue are combined in various ways to reproduce other colours. In specific relation to graphics, RGB color model is the display of colors on display, such as a television or a computer’s monitor. Through a combination of red, green, and blue intensities, many colors can be represented. Typical display adapters in 2007 use up to 24bits of information for each pixel. This is usually apportioned with 8 bits each for red, green and blue, giving a range of 256 possible values for varying colour intensities.

What is the difference between VECTOR and BITMAP graphics? Explain both terms.
2) What is the difference between VECTOR and BITMAP graphics? Explain both terms.
Vector may be defined as photo designed using mathematical paths i.e defined through points 
creating lines & curves etc. When enlarged or magnified the picture does not loose any quality. Clearly represented by the picture.

Clearly represented by the picture.In comparison to Bitmap which is developed through clusters of pixels or dots. Images boosting with high complexity of colour i.e the aligned photograph looks acute whilst viewed at 
recommended resolution however the pixels do not fit that well together when magnified. These are usually in the form of Bitmaps.

What is a pixel?
1.) What is a pixel?
A pixel refers to the smallest element displayed on a video screen. E.g. Television, computer, camcorder. A video screen may contain thousands of pixels each consisting of one or more dots. Pixel derives from "pix" (for picture) plus "el" (for element).
