// The FontMatchInfo contains a list {attribute, value} pairs. Attributes
|
|
// can be added on the fly. There are however a set of predefined attributes.
|
|
// Attributes are ConstCStrings.
|
|
//
|
|
// The predefined attributes and the type of their values are
|
|
// Attribute Type of Value
|
|
// ---------------------------------
|
|
// "nfFmiName" ConstCString
|
|
// "nfFmiCharset" ConstCString
|
|
// "nfFmiEncoding" ConstCString
|
|
// "nfFmiWeight" int
|
|
// "nfFmiPitch" int
|
|
// "nfFmiStyle" int
|
|
// "nfFmiUnderline" int
|
|
// "nfFmiOverstike" int
|

// "nfFmiPanose" int[]

// "nfFmiResolutionX" int

// "nfFmiResolutionY" int
|
|
// ----------------------------------------------------------------------
|
|
// NOTE:
|
|
// - FMI always takes a copy of the strings that are passed in either
|
|
// for the attribute or value. On destruction, it frees all the strings.
|
|
// For int and other values, the value is stored as such. It is the
|
|
// responsibility of the creator of the fmi to free them.
|
|
//
|
|
// - user defined attributes are not implemented yet. Issues:
|
|
// 1. We were planning on using a Fmi cache. Fmi<->Font mapping is
|
|
// maintained in the broker. Checking FMI equality becomes critical.
