Re: [jira] Created: (HARMONY-1456) [classlib][awt]java.awt.Font.hasUniformLineMetrics() return true on Harmony while RI returns false
Hi, community!
I found for java.awt.Font.hasUniformLineMetrics() RI returns false for all
fonts (physical/logical) while Harmony returns true for physical and false
for logical.
Spec says: "Checks whether or not this Font has uniform line metrics. A
logical Font might be a composite font, which means that it is composed of
different physical fonts to cover different code ranges. Each of these fonts
might have different LineMetrics. If the logical Font is a single font then
the metrics would be uniform. ". Thus I find reasonable to return true for
physical fonts, as they are single.I assume that it is a non-bug difference
from RI.
Any thoughts on this issue?
Regards,
Ilya.

Posted by Oleg Khaschansky <ol...@gmail.com>.
I wanted to say that if RI always returns false then there's very
small probability that any application developed for RI's classlib
uses this.

It may have sence if the application uses certain metrics for logical fonts
according to the hasUniformLineMetrics() returned value. E.g. baseline
offsets or lines thicknesses may be different for the physical fonts, that
are composing logical font. Probably some applications would use font
metrics if the hasUniformLineMetrics() returned true and use redefined
values for such metrics if returned value is false, depending on the
situation. (It is only a guess;)
