Prior to this commit the returned values were always normalised to the
value returned by getHeightInPoints().
I.e. getAscentInPoints() + getDescentInPoints() would always equal
getHeightInPoints(), even if ascent or descent overrides were in place.
With this change in place getAscentInPoints() + getDescentInPoints()
will always equal
getHeightInPoints() * (getAscentOverride() + getDescentOverride())
JUCE classes don't use this value for layout logic, so this commit
causes no visible changes in how JUCE draws text.
After reviewing the NSAttributedString API it seems justified to have
two different functions for additive and multiplicative line spacing
settings. For NSAttributedString they are setLineSpacing and
setLineHeightMultiple.
Using this function, when appropriate, exercises it lessening the
likelihood of code rot.
Previously using the FontForRange type was motivated by hiding the
RangedValues type in case we wanted to expose the ShapedText API. This
introduced unnecessary conversions between FontForRange and
RangedValues<Font>.
Since the original function template has been exposed, we can now use it
directly. Also ShapedText::Detail has been removed, because it wouldn't
work across module boundaries.
This restores the JUCE 7 behaviour when the JUCE 8 font fallback
mechanism fails to resolve a non-null Typeface::Ptr. This behaviour is
significant when the base font specified is not available on the system.
The issue prior to this commit would be observable when using the
GlyphArrangement functions e.g. addFittedText.
This is a fix for a regression introduced in
9223805b9c.
Prior to this a soft break could occur between two characters printed in
different fonts, even though there was no break opportunity there in the
Unicode string.
This fixes an undesired behaviour where squashing the text using
GlyphArrangement::addFittedText would only squash the visible glyphs but
not the additional kerning space between them.
This commit fixes a regression added during the ShapedText based rewrite
of the class. The minimumHorizontalScale parameter was mistakenly
interpreted as an absolute scale, whereas its meaning in the old
implementation was a relative scalar applied to the Font's horizontal
scale.
This behaviour, previously available in JUCE 7, was missing since the
JUCE 8 changes related to Unicode text drawing.
With this commit, words that are too long to fit in a line are again
broken up, with the caveat, that we can expect this approach to produce
quirks with bidirectional text. We don't expect that such a feature
could be satisfactorily provided for bidirectional text, so this is a
stopgap measure for legacy applications.
Since 4122427748 assertions are guarding
the FontOptions::withName, withStyle and withTypeface member functions.
Since then the only way to replace an existing typeface without hitting
these assertions is to clear all three fields before calling
withTypeface, which then sets all three values. It is always legal to
just clear an existing Typeface and rely on the name and style fields.
Previously, code such as the following would return a smaller string
width for larger tracking values:
juce::Font f { juce::FontOptions{}.withPointHeight (16.0f) };
const auto g = f.withExtraKerningFactor (1.0f);
const auto a = f.getStringWidth ("foobar");
const auto b = g.getStringWidth ("foobar");
With this change applied, the width 'b' is greater than the width 'a',
as expected.
