This article shows you what is the RGB index format, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

This paper gives a brief introduction to the RGB index format and introduces why it is simple. The reason is that these formats are relatively old and space-saving, and the cost of storage in the early stage of computer development is still very high, but the color performance is very limited. With the continuous reduction of storage costs and the higher and higher visual experience needs of users, these formats are basically abandoned and no longer used. Therefore, the significance of in-depth study is not very great.

Foreword:

With regard to color palettes, it can be simply understood as a two-dimensional table mapped to colors by numbers. Such as the 01 index, which indicates red. Using the index format of RGB, the value stored in red pixels is the index.

Introduction to RGB index format:

RGB1:

Each pixel is represented by a bit, and the range of colors that can be represented is two colors, the most traditional black and white. 1 bit can only represent two values of 0 and 1. A color palette is required, but it contains only two colors.

RGB4:

Each pixel is represented by 4 bit, and the index range that 4 bit can represent is 0-15, a total of 16. That is, it can represent 16 colors. That is, the palette contains 16 colors.

RGB8:

Each pixel is represented by 8 bit. Eight bit can represent an index range of 0255256 in total. That is, it can represent 256 colors. That is, the palette contains 256 colors.
