halftone_converter Struct Reference

Halftone converter run-time data. More...

Data Fields
unsigned	right_left:1
signed int	dotval [2]
signed int	threshold
size_t	pixel_count
conv_type *	sliding_lines [2]

Detailed Description

Note

The 'signed short' dot values are for calculation only. Feed-in contains values 0x00…0xff and also after the processing they contain only dotval[0] or dotval[1] values.

Field Documentation

right_left

unsigned right_left

half tone algorithm direction left->right or right->left

dotval

signed int dotval[2]

dotval[0]: do not print value (e.g. 0), dotval[1]: print value (e.g. 255) FIXME nicht anders herum?

threshold

signed int threshold

Threshold to chose one of the dotval values, below threshold: dotval[0], else dotval[1]

pixel_count

size_t pixel_count

width of target image in pixels

sliding_lines

conv_type* sliding_lines[2]

Two lines of the source image to process, size corresponds to "pixel_count"
