Learning NI

This week in class we used a website called Learning NI to send information electronically through the available online forums.






Here is a picture of the homepage. One would type in their C2k user name and password here.

Here, there is a section in the lower left hand side of the page titled All Courses. Here I select the A2 Applied ICT Multimedia folder to bring mr to the forum page.

I then clicked on workspace in the top right corner to open up a new window.

This is the window to post comments to each other member of the group.

How I made the Tram and my Composite Images.

Tram

I made the tram (below) in a programme called google sketch up. I started off with a long 2D rectangle and i used the Push/Pull feature to make the rectangle a 3D cuboid. With pencil tool i drew a horizontal line across the face of the cuboid and i used the move feature to make the face side pointed, more like the front of a tram would be.

On the side of the cuboid i drew out several square holes to act as windows for the tram. I also installed a large cuboid hole on the top face of the tram to act as a windscreen. Below the windows on the side I drew a line as a design to make the tram look a bit more interesting. I also coloured the outside of the veichle a silver metal colour.

Internally i installed bucket seats all around the tram. I also gave the interior a carpet floor and tiled walls. In the drivers area i drew out 3 circles and coloured them different colours to make them look like control panel buttons.

Composite Images

To create these images i used a programme called The GIMP. I first found pictures of well known areas in Derry such as Shipquay Street and The Bogside. I then found suitable pictures of transport veichels to super impose onto the images of Derry.

In GIMP the first thing to do is to open the picture of the veichle (Tram, Gondola etc.). Then I edited the image so as none of the background would be there. I then superimposed the image of the tram onto the background of Derry, and edited it accordingly.

What Are The Characteristics of The Following Graphics File Formats: GIF, PNG, JPEG, XCF, PSD, SVG.

DEFINITION:
GIF: The Graphics Interchange Format (GIF) is an 8-bit-per-pixel bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.

The format uses a palette of up to 256 distinct colors from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for more simple images such as graphics or logos with solid areas of color.

PNG: Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace the GIF format, as an image-file format not requiring a patent license. PNG is pronounced "ping".

PNG supports palette-based (palettes of 24-bit RGB colors) or greyscale or RGB images. PNG was designed for transferring images on the Internet, not professional graphics, and so does not support other color spaces (such as CMYK).

JPEG: In computing, JPEG (pronounced JAY-peg) is a commonly used method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the standard. The group was organized in 1986, issuing a standard in 1992 which was approved in 1994 as ISO 10918-1. JPEG is distinct from MPEG (Moving Picture Experts Group) which produces compression schemes for video.

XCF: XCF, short for Experimental Computing Facility, is the native image format of the GIMP image-editing program. It supports saving each layer, the current selection, channels, transparency, paths and guides. However, unlike a PSD file, the undo history is not saved in an XCF file.

PSD: The .PSD (Photoshop Document) format stores an image with support for most imaging options available in Photoshop. These include layers with masks, color spaces, ICC profiles, transparency, text, alpha channels and spot colors, Clipping paths, and duotone settings. This is in contrast to many other file formats that restrict content to provide streamlined, predictable functionality. Photoshop's popularity means that the .PSD format is widely used, and it is supported to some extent by most competing software.

SVG: Scalable Vector Graphics (SVG) is an XML specification and file format for describing two-dimensional vector graphics, both static and animated. SVG can be purely declarative or may include scripting. Images can contain hyperlinks using outbound simple XLinks. It is an open standard created by the World Wide Web Consortium's SVG Working Group.

What Is an Alpha Channel? How Can This Be Useful In Your Coursework Project?

DEFINITION:
Alpha Channel: In computer graphics, 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.

This will be useful in my future coursework as, one of the aspects of the coursework is to create a new method of transport for Derry. I will have to produce photographic evidence of what the system will look like in Derry. This is managable through the utilisation of a computer programme called " The GIMP". This programme will create an alpha channel for a jpeg photo so it can be adapted onto a backround picture of Derry.

IN MY OWN WORDS:
Alpha composing is combining different parts of pictures with one another to produce a form of transparency. It is used to combine a computer image with a piece of live footage.

What Does “RGB” Have To Do With Graphic Files?

DEFINITION:

The RGB color model is an additive model in which red, green, and blue (often used in additive light models) are combined in various ways to reproduce other colors. The name of the model and the abbreviation ‘RGB’ come from the three primary colors, red, green, and blue and the technological development of cathode ray tubes which could display color instead of a monochrome phosphoresence (including grey scaling) such as black and white film and television imaging.

LINK: http://en.wikipedia.org/wiki/Rgb

IN MY OWN WORDS:

The three colours, Red, Green and blue are combined to make a positive image. These colours can also be combined to make different colours.The initials RGB come from the colours Red, Green and Blue.
