cm1027_block_data_header Struct Reference

Brother 1027 encoding method data block's binary header. More...

Data Fields
uint16_t	border_left
uint16_t	border_top
uint8_t	line_cnt
uint16_t	word_cnt
uint16_t	data [0]

Detailed Description

Note

This header needs to be packed, because its memory layout is important.

Attention

All multibyte values need to be encoded in big endian notation.

Note

The documentation I found doesn't say the line_cnt member must be encoded as -1 of the real value
The member pixel_cnt is defined as horizontal 16 bits words in one line.

Field Documentation

border_left

uint16_t border_left

Left border in [dots] (e.g. leftmost dot in this data block)

border_top

uint16_t border_top

Top border in [lines] (e.g. page's line number of the band's top line)

line_cnt

uint8_t line_cnt

Count of lines encoded in this data block (-1, e.g. "1" means two lines)

word_cnt

uint16_t word_cnt

Count of [words] in all lines of this data block

data

uint16_t data[0]

The encoded block data starts here (max. C1027_MAX_WORDS_IN_ONE_BLOCK)
