unsigned height

unsigned idx

unsigned width

unsigned y

Detailed Description

Parameters of a text line segment.

Every text line has one segment at the least.

Text line can have multiple segments. Additional segments can appear as a result of automatic text wrap.

fe::LineInfo for the "qwerty123" text line:

idx = 0;

y = 0;

width = 155;

height = 42;

ascent = 33;

firstByteIdx = 0;

bytes = 9;

Two fe::LineInfo-s for two segments of the "qwerty123" text line. The second segment is a result of automatic text wrap.

The first text line segment:

idx = 0;

y = 0;

width = 116;

height = 42;

ascent = 33;

firstByteIdx = 0;

bytes = 6;

The second text line segment:

idx = 1;

y = 42;

width = 39;

height = 24;

ascent = 18;

firstByteIdx = 6;

bytes = 3;

Member Data Documentation

unsigned fe::LineInfo::idx

Text line segment index. The value is within the [0, breaks] range, where breaks is the number of additional segments the given text line has as a result of automatic text wrap.

unsigned fe::LineInfo::y

Vertical offset of the text line segment's top left corner from the top left corner of the first text line segment of the given text line. Measured in pixels.

unsigned fe::LineInfo::width

Text line segment width. Measured in pixels.

unsigned fe::LineInfo::height

Text line segment height. Measured in pixels.

unsigned fe::LineInfo::ascent

Text line segment ascent. Measured in pixels.

unsigned fe::LineInfo::firstByteIdx

Text line segment first byte index. The value is relative to the first byte of the given text line.

unsigned fe::LineInfo::bytes

Text line segment size in bytes.
