Flash technology for creating simple Web pages, presentations, animations, online games ... Flash uses vector graphics, which gives us the advantage that Flash applications are small, which also helped pervasive on the Internet. When working with computer graphics are used to store two types of image - bitmap and vector graphics. As we mentioned flash uses vector graphics, which are now a little zoom.

Vector Graphics

It's the kind of information you describe in computer graphics. Unlike bitmap (raster) graphics are vector graphics describing the image using vectors rather than in terms of points (pixels) as the graphics bitmap. A vector image is then composed of units such as lines, points, curves.

Advantages:
- In reducing or enlarging no loss of quality
- We work with each property separately
- Smaller than the bitmap image

Disadvantages:
- Acquisition of more complex image than bitmap graphics
- The big picture of sophistication graphics processor-intensive

Bitmap (raster) graphics

In this type of graphic image is described by the individual points (pixels). These are arranged in a grid where each point has a color (RGB) and location. We are two basic criteria that determine
quality - resolution and color depth. This is known when using a digital camera. Here we are talking about so-called PPI (pixels per inch) - dots per inch. If he had a resolution of 1 megapixel digital camera, so the image will be composed of 1000 x 1000 pixels. This latter criterion is the DPI (dots per inch). - Printing dots per inch.

Advantages:
- You capture the image using a scanner or digital camera.

Disadvantages:
- Heavy demands on data instead of
- Deterioration in the size of the
- Due to limited grid zooming

Flash

The flash technology can have the following formats:

. Swf file - a small file size, you can play it in your web browser

. Exe - the file type to run in Windows

The main advantages of using HTML to

- Speed ​​and simplicity
- Easy to work with data
- Compatibility with all browsers
- Import video, pictures and sound
- To play animation
- Wide range of export Flash animations

The main drawbacks to using HTML

- Relatively high performance PC
- The need to install plug-ins
- Can not create tables
- Protection against misuse of application (. Swf format is open)
- Unfit for mostly text site
