Analysis

Overview

Sophie needs support for justified text. This task has to provide both the UI and the needed algorithms for test justification.

Task requirements

• TextParagraphHud should provide a button for justified alignment. After pressing it, the text should be aligned justified, meaning:
  • Text is aligned along both the left and right frame border;
  • Spacing between words is equally distributed;
  • Spacing between letters is not modified;
• The algorithm for justification should be easily changeable with an alternative implementation.
• If the suggested algorithm requirements tend to produce bad layout (whitespace rivers, loose lines, etc.) or downgrade the performance by more than 20% (measured by the text performance tests run on left-aligned and justified text), they might be changed.
• The algorithm should not significantly slow down text performance.

Implementation idea

At this revision we want something simple - we take the width of the segment/line, take out the width of the text, and distribute the space equally between words.

How to demo

Insert a text frame in Sophie, type some text and align it justified.
