How to make a 256-color bitmap file

The specific operation steps are as follows.

1, left-click my menu in the lower left corner of the desktop. Find the Windows attachment. 2. Find the attached drawings. 3. Open the drawing tool. 4. Insert the picture to be saved as a 256-color bitmap. 5. Select Save As in File. 6. Set the storage format to 256-color bitmap, but this method will distort the picture.

The number of color digits is in binary digits, and the number of colors is expressed in digits. The three primary colors RGB are divided into 256 gray levels, and the combined color is 256× 256× 256 = 16700000, commonly known as 24-bit or 24-bit color (2 to the 24th power). 256 colors should be represented by 8-bit binary numbers, that is, 2 to the 8 th power, so we call 256-color graphics 8 bitmaps. Similarly, if 65536 colors can be displayed, it is the bitmap of 16, which is the second power of 16. In graphic mode, the total number of colors is determined by the number of digits of each drawing point.
