Apache OpenOffice (AOO) Bugzilla – Issue 21551
Typographical Problem in Draw
Last modified: 2017-05-20 11:29:43 UTC
Inserting some Text in a shape will result, depending on the font and fontsize, in different rendering of the font-kerning. The spaces between two characters vary between some disctance between the two characters and even some undercut. Examples: Open new Draw document, insert a text-shape, enter "Ac rt" Font Size Result (Ac) Result (rt) Arial 9pt undercut very small distance 10pt distance undercut 10.5pt distance distance 11pt no disctance very small distance 12pt distance undercut 13pt small disctance small disctance Bitstream 9pt distance small disctance vera sans 10pt distance undercut 10.5pt distance undercut 11pt distance small disctance 12pt distance distance 13pt small disctance small disctance Tahoma 9pt distance undercut 10pt distance distance 10.5pt small disctance small disctance 11pt small disctance undercut 12pt distance distance 13pt disctance small undercut Verdana 9pt distance distance 10pt distance undercut 10.5pt disctance disctance 11pt disctance small disctance 12pt distance undercut 13pt disctance no disctance Achim

Reproducible in a current internal version. Thanks for the fantastic document!

Malte, is that you or Herbert?
To get zoom independent layout for text breaking etc. a reference device is used. Currently for Draw this reference device is the screen at 100% zoom. When the actual display is used at a different zoom level there are rounding issues especially for small fonts. HDU->AHofmann: When you enable the checkbox Tools->Options->Drawing->General->Use printer metrics for formatting the higher resolution of the printer will result in better behaviour for high zoom levels. For display at 100% zoom levels the current default is optimal though. HDU->AF: I suggested to KA to also have the higher resolution reference device the Writer also uses for formatting and he recommended to forward this enhancement request to you. Since there is a delicate balancing for optimal printing, optimal display at 100% zoom and optimal display at different zooms maybe the UI team should think about it first.
Superb response, thank you. The hints from HDU are very valuable. The result enabling the checkbox Tools->Options->Drawing->General->Use printer metrics for formatting improves the result drastically. But enabling this checkbox doesn't only influence the quality on the display for 100% and higher zoom levels, it also improves the printing quality as well. Exporting documents to a PDF-File, inherit the quality differences as well, so I assume, it's not only a rendering problem for the display. Anyway, thanks
Accepted.
