CTFontDescriptorMBS.CreateCopyWithFamily(orignal as CTFontDescriptorMBS, family as String) as CTFontDescriptorMBS

original: The original font descriptor reference.
family: The name of the desired family.

Returns a new font reference with the original traits in the given family, or nil if none found in the system.

CTFontDescriptorMBS.CreateCopyWithSymbolicTraits(orignal as CTFontDescriptorMBS, symTraitValue as Integer, symTraitMask as Integer) as CTFontDescriptorMBS

// find PostScript names for a font
const nameOfAFont = "Arial"

Var FontName as string
Var FontFamilyName as string
Var FontPostscriptName as string
Var FontPostscriptNameBold as string
Var FontPostscriptNameItalic as string

original: The original font descriptor reference.
symTraitValue: The value of the symbolic traits. This bitfield is used to indicate the desired value for the traits specified by the symTraitMask parameter. Used in conjunction, they can allow for trait removal as well as addition.
symTraitMask: The mask bits of the symbolic traits. This bitfield is used to indicate the traits that should be changed.

Returns a new font descriptor reference in the same family with the given symbolic traits, or nil if none found in the system.

Requires Mac OS X 10.9 or newer.

CTFontDescriptorMBS.CreateWithAttributes(attributeValues as Dictionary) as CTFontDescriptorMBS

The provided attribute dictionary can contain arbitrary attributes that are preserved; however, unrecognized attributes are ignored on font creation and and may not be preserved over the round trip from descriptor to font and back to descriptor.

CTFontDescriptorMBS.CreateWithNameAndSize(Name as string, Size as Double = 0.0) as CTFontDescriptorMBS

Var c as CTFontDescriptorMBS = CTFontDescriptorMBS.CreateWithNameAndSize("Times", 12)
MsgBox c.AttributeValue(c.kCTFontFamilyNameAttribute)

name: The PostScript name to be used for the font descriptor as a string.
size: The point size. If 0.0, the font size attribute (kCTFontSizeAttribute) is omitted from the returned font descriptor.

Return sa new font descriptor reference with the given PostScript name and point size.
