Hi all,
According to the documentation, the leading of a paragraph depends on
the font. However, when I create a paragraph using the
ElementFactory, passing in a property that corresponds to the font
size, the leading is not computed based on that size. Below is code
that demonstrates this effect -- the third paragraph's leading is not
computed based on font size. Is this a bug? A feature? How do I get
around it?
My goal is to maintain a stack of attributes. So, for example, if I
want some text to be italic, I copy the top of the attribute stack,
add the italic attribute to it, push that onto the stack, and use
that set of attributes in a new chunk. Once I'm done with the chunk,
I can pop the attributes off the stack, and continue adding chunks
using the previous attributes. This would be useful for processing
HTML, where you could get a run of characters, followed by the italic
open tag, some more characters, the italic close tag, and then more
characters.
Any ideas?
Thanks,
--Rob
