Bug ID: 168251
Summary: Add glyph scaling to paragraph justification
Product: LibreOffice
Version: Inherited From OOo
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Minor automatic glyph scaling within a minimum/maximum range can minimize too
big word spacing, rivers of justified lines, allowing to typeset narrow columns
and more readable text. Combined with custom word spacing and letter spacing,
it is the basic tool of DTP software to improve typography and readability.
Note: without optical sizing, e.g. variable fonts with "wdth" axis, the
suggested/allowed minimum and maximum glyph scaling only a few percent, because
distortion of the glyphs destroys their balanced stroke thickness, i.e. the
design of the letters.
Steps to Reproduce:
Create a narrow column with justified text.
Actual Results:
Too big word spacing, often rivers (overlapping word spacing of consecutive
lines).
Expected Results:
Closer to the desired word spacing, no rivers.
Reproducible: Always
User Profile Reset: No
