示例1: checkForGenericFamilyChange
void FontBuilder::checkForGenericFamilyChange(const FontDescription& oldDescription, FontDescription& newDescription)
{
if (newDescription.isAbsoluteSize())
return;
if (newDescription.isMonospace() == oldDescription.isMonospace())
return;
// For now, lump all families but monospace together.
if (newDescription.genericFamily() != FontDescription::MonospaceFamily
&& oldDescription.genericFamily() != FontDescription::MonospaceFamily)
return;
// We know the parent is monospace or the child is monospace, and that font
// size was unspecified. We want to scale our font size as appropriate.
// If the font uses a keyword size, then we refetch from the table rather than
// multiplying by our scale factor.
float size;
if (newDescription.keywordSize()) {
size = FontSize::fontSizeForKeyword(&m_document, newDescription.keywordSize(), newDescription.isMonospace());
} else {
Settings* settings = m_document.settings();
float fixedScaleFactor = (settings && settings->defaultFixedFontSize() && settings->defaultFontSize())
? static_cast<float>(settings->defaultFixedFontSize()) / settings->defaultFontSize()
: 1;
size = oldDescription.isMonospace() ?
newDescription.specifiedSize() / fixedScaleFactor :
newDescription.specifiedSize() * fixedScaleFactor;
}
newDescription.setSpecifiedSize(size);
}示例2: updateSpecifiedSize
void FontBuilder::updateSpecifiedSize(FontDescription& fontDescription, const ComputedStyle& style)
{
float specifiedSize = fontDescription.specifiedSize();
if (!specifiedSize && fontDescription.keywordSize())
specifiedSize = FontSize::fontSizeForKeyword(&m_document, fontDescription.keywordSize(), fontDescription.isMonospace());
fontDescription.setSpecifiedSize(specifiedSize);
checkForGenericFamilyChange(style.fontDescription(), fontDescription);
}示例3: setFontSizeInherit
void FontBuilder::setFontSizeInherit(const FontDescription& parentFontDescription, float effectiveZoom)
{
FontDescriptionChangeScope scope(this);
float size = parentFontDescription.specifiedSize();
if (size < 0)
return;
scope.fontDescription().setKeywordSize(parentFontDescription.keywordSize());
setSize(scope.fontDescription(), effectiveZoom, size);
