Picture data

Picture encoding format:

Start 2 bytes 0D 0A (if 0D 0B is supporting a single exposure layer)

Total number of combinations: 4 bytes

data

Single pixel data is encoded with variable length, and the pixel data is represented by one byte:

Bit: 07-01 gives the pixel value (the original pixel is rounded down to the last bit)

Bit: 00 indicates whether this is a single pixel or a continuous pixel. (0 is a single pixel and 1 is a continuous pixel)

If it is a continuous pixel, the number of pixels is given by the following 1~4 bytes (Note: When the data length of a single pixel requires more than one byte for description, the bytes are arranged in big-endian order. This is the The only case in the file format series where numbers are represented by big endian), the specific instructions are as follows:

0b0xxxxxxx: 7-bit run length.

0b10xxxxxx: 14-bit running length, composed of 05-00 bits of this byte and the next byte, among which: 05-00 bits are high bits.

0b110xxxxx: 21-bit running length, composed of 04-00 bits of this byte and the next two bytes, of which: 04-00 bits are high bits.

0b1110xxxx: 28-bit running length, composed of 03-00 bits of this byte and the next three bytes, among which: 03-00 bits are high bits.

Examples are as follows:

0xFE is a single pixel with a value of 254.

0xFF 0x2a is a 42-pixel operation with a value of 254.
