David Goldfarb created BATIK-1219:
-------------------------------------
Summary: Batik measures text height incorrectly
Key: BATIK-1219
URL: https://issues.apache.org/jira/browse/BATIK-1219
Project: Batik
Issue Type: Bug
Components: Bridge
Affects Versions: trunk
Reporter: David Goldfarb
Attachments: tqbf2-outer.svg, tqbf2.pdf
Batik calculates the area behind text (e.g., for feFlood in a filter) by
calculating a tight rectangle bound the character glyphs.
Chrome, Firefox and Edge all calculate a somewhat looser rectangle, including
the full line height. Their behavior seems correct, as it results in a much
more pleasing and intuitive effect when multiple text segments are filtered in
one line of text.
Attached files:
- tqbf2-outer.svg - a file demonstrating this problem. This can be loaded
directly in any current browser
- tqbf2.pdf - the results in Batik. This differs from the browser results.
Proposed fix:
