CGPSConverterMessageCallback

Declaration

typealias CGPSConverterMessageCallback = (UnsafeMutableRawPointer?, CFString) -> Void

Parameters

• info:

  A generic pointer to private data shared among your callback functions. This is the same pointer you supplied to Init(info:callbacks:options:).

• message:

  A string containing the message from the PostScript conversion process.

Discussion

There are several kinds of message that might be sent during a conversion process. The most likely are font substitution messages, and any messages that the PostScript code itself generates. Any PostScript messages written to stdout are routed through this callback—typically these are debugging or status messages and, although uncommon, can be useful in debugging. In addition, there may be error messages if the document is malformed.
