1. Vector drawing
1.1. Vector-drawn graphics
1.1.1. Application of vector-drawn object
1.1.2. How vector-drawn image work
1.1.3. Vector-drawn image versus bitmaps
1.2. Vector-drawn images are used in the following areas
1.2.1. Graphic artist designing for the print media
1.2.2. Computer-aided design (CAD) programs needed by architects and engineers
2. Window Format
2.1. The most commonly used image file format on Window is DIB, also known as BMP
3. Natural light and color models
3.1. Additive color
3.1.1. In the additive color method, a color is created by combining colored light sources in three primary colors-red, green, and blue (RGB)
3.2. Subtractive color
3.2.1. In the substrate color method,color is create by combining colored media such as painted or ink
3.3. Dithering
3.3.1. Usually, digitized images are 24 bit, 16 million color depth.
4. Macintosh formats
4.1. PICT is a versatile format developed by Apple.
5. JPEG(Joint Photographic Expert Group)
5.1. Commonly used standard method of compression for photographic images
6. Cross platform formats
6.1. JPEG, GIF, and PNG- Most commonly used format on the Web
7. GIF
7.1. 8-bit per pixel, bitmap image format commonly used by the world wide web
8. PNG
8.1. Support more than 16.7 million colors.
8.2. Use lossless compression technique
9. Image File compression
9.1. Lossless compression
9.1.1. Every single bit of data that was originally in the file is uncompressed.All if the information is completely restored
9.2. Lossy compression
9.2.1. Reduces a file by permanently eliminating certain information,especially redundant information
10. Vertor graphic
10.1. Advantages
10.1.1. Vector images use less memory space
10.2. Disadvantages
10.2.1. Object/drawing cannot have texture
10.2.2. Cannot be used for photorealistic images
10.3. New node
11. Still image
11.1. Bitmaps(raster)
11.1.1. Bitmap is a simple matrix of the tiny dots thatform an image and are displayed on a screen or printed
12. Bitsmap
12.1. Advantages
12.1.1. Can have different textures on the drawing ; detailed and comprehensive
12.2. Disadvantages
12.2.1. Large File size
12.2.2. Not easy to make modification to objects/drawings
12.2.3. Resizing a bit mapped image requires either duplicating pixels
12.2.4. Graphics become "blocky" when the size is increased.
