A tener en cuenta a tope obiWan:
Cualquier abuso pa´cualquier lado, hace mal.
Ok, aquí algo re cope:
"...a bitmap is made up of pixels. It can be thought of as a grid of color values, which designate a particular color for each and every pixel. Each pixel is a cell in the grid. A 100 x 100 pixel bitmap can be described by a grid of 10,000 color values, one for each pixel.
Each color value in a bitmap is a binary number. A binary number is made up of bits, whose values can be either 0 or 1. This binary number will differ in length, depending upon the color depth of the bitmap. The color depth of a bitmap determines the range of possible color values that can be used in each pixel. For example, each pixel in a 24-bit image can be one of roughly 16.8 million colors. Those colors are formed by mixing together varying quantities of three primary colors: red, green, and blue. The three main colors are called channels. It follows that:
- Each channel can have 256 possible values (0255).
- 256 * 256 * 256 = 16.8 million
- 256 decimal is 11111111 in binary.
- This binary number is 8 bits long. 8 bits is 1 byte.
Therefore the color value for each pixel in a surface created by Flash Player is 32 bits long, or 4 bytes.
4 * 8 = 32 bit
The bitmap that is created by Flash Player to represent the visual state of a movie clip when you turn bitmap caching on will have the same dimensions (width and height) as the movie clip.
A cached movie clip that is 100 x 100 pixels has 10,000 pixels.
100 * 100 = 10,000 pixels
Each of those pixels will be 32 bits or 4 bytes. Therefore the movie clip will use an extra 40,000 bytes of memory.
10,000 * 4 = 40,000 bytes
There are 1024 bytes in 1 kilobyte (K). So, 40,000 bytes can also be said to be roughly 40 kilobytes (40K).
