We are using shape nodes to display components. We are showing short and long labels depends on zoom level(below 25 percent short label and above 25 percent long labels).
However in some zoom level shape node gets blank and shows empty box. We have identified the reason and decreasing font size solved the problem.

However this is not generic solution, and if text length shown in shape node varies same problem occurs again.

Is there any algorithm/solution which will ensure that text in shape node will display no matter what the text size? We are using styled text with following settings

         node.getTextFormat().setNoWrap( false);
         node.getTextFormat().setHorizontalAlign( Align.Near);
         node.getTextFormat().setVerticalAlign( Align.Near);

Thanks in advance

Our developer's improved text rendering here, in case you prefer not to use the WrapAtCharacter option -
https://mindfusion.eu/_beta/jdiag46.zip

Now if a text line can't fit a single word, it is drawn clipped instead of stopping rendering there. In addition, a new WrapOverflowingSingleWordLines property lets you wrap only such long words, but otherwise keep wrapping lines only at word boundaries.
