4.++Digital+Images



//**Focus:**// Images are either Bitmap or Vector, and working with each one presents its own advantages and disadvantages.

//**Time:**// Approx. Cycle To Cycle (- )

//**Content To Be Learned:**//
 * Digital images are created using either pixels or vector shapes.**
 * 1) Bitmap are those which generate a picture made up for thousands of pixels (dots).
 * 2) Bitmaps images are measured in dpi and the higher the dpi the clearer the image.
 * 3) All bitmap programs have a range of tools similar to those you would use if you were painting with a brush and many have unique ones specific for technologically manipulation.
 * 4) There are some difficulties with Bitmap programs, especially using a mouse, and jagged edges.
 * 5) Techniques such as anti-aliasing., using tablets, etc. help overcome some of these problems.
 * 6) Vector programs create objects using a series of shapes, gridlines, etc.
 * 7) Vector programs' tools differ from Bitmap programs.
 * 8) Objects are copied, pasted, layed on top of one another, grouped together, etc. to create images.
 * 9) Vector pictures can be made larger or smaller by any amoutn without change in quality.
 * 10) Advanced vector programs are able to produce accurate scale drawings, and utilize distortions and other effects.


 * //Skills To Be Learned/Reviewed://**
 * 1) inserting shapes
 * 2) using gridlines to accurately place shapes
 * 3) layering shapes so they interact to work together to create images[[image:http://c1.wikicdn.com/i/c.gif width="22" height="22" caption="Insert Table"]]
 * 4) filling shapes and line with colour
 * 5) grouping objects
 * 6) adding effects to shapes and objects

Research the Internet to find an interesting link (article, video, etc.) about the use of graphics in society that you think is relevant to this unit. It can be about vector or bimap or both.
 * Expanding Our Knowledge:**


 * Name || Link/Embed || Reason it is relevant to our unit ||
 * Masatoshi || [] || I think this website is relevant to our unit. It explain about how the vector and bitmap is useful. It includes the information about the file format of vector and bitmap. It also compares about which one is more useful depending on the case. ||
 * Reina || http://www.billiondollargraphics.com/WhyUseGraphics.pdf || In modern media, graphics can convey more than words. If you want to sell a product, you have to use graphics effectively. I think that this link is relevant to our unit as it proves that attractive graphics have a power to grab attention from people. Therefore, we have to make and use graphics, thoughtfully. ||
 * Rio || http://www.eastbywest.com/pub/vectorbitmap/ || this website is relevant because it talks about why we should use both vectors or bitmap image. It also talks about the advantages and disadvantages like the pixel and how much memory it takes up. ||
 * Seung Jae || [] || This website tells about the advantage and disadvantages of vector and bitmap. It focuses more on bit map and show the various types of the bit map images. Also it helps to show which one is preferable ||
