Hi,
I'm having a problem with osgText::Text since r12068. Everything is fine
up to r12067, so I'm absolutely certain it's related to this commit:
http://www.openscenegraph.org/projects/osg/changeset/12068
With this change, osgText::Text has excessive character spacing.
Characters are so far apart that any text is unreadable (only 2-4
characters fit on the screen using "usual" character sizes/widths...).
I've attached a patch which "fixes" the issue for me and restores
"normal" spacing. However, it's simply reverting the relevant changes of
r12068. There probably was a good reason to change these lines in the
first place. But I'm at loss why it's not working for me. Maybe
something was broken - or is there anything that requires applications
to be adapted when using >=r12068 osgText::Text?
That's a sample of how the application is using osgText - nothing fancy
really:
text = new osgText::Text;
text->setFont(font);
text->setCharacterSize(0.06);
text->setColor(osg::Vec4(1, 1, 1, 1));
text->setPosition(osg::Vec3(0, 0.82, 0));
text->setAlignment(osgText::Text::CENTER_CENTER);
text->setText(Message);
Any ideas?
cheers,
Thorsten
