PhotoPrintingIntent 列舉

定義

指定列印相片時的輸出品質。 印表機驅動程式會將 PhotoPrintingIntent 轉換成解析度和其他品質因素的量化值。The printer driver translates the PhotoPrintingIntent into quantitative values for resolution and other quality factors.

備註

此類型的值主要用於下列用途:The values of this type are used primarily for these purposes:

值永遠不會用於物件的PrintCapabilities屬性中。 UnknownThe Unknown value is never used in properties of PrintCapabilities objects.

您絕對不應該將PrintTicket屬性設定Unknown為。You should never set a PrintTicket property to Unknown. 如果某些其他PrintTicket產生的應用程式已建立將相片列印意圖功能設為無法辨識的選項 (也就是在列印架構中未定義的選項), 則PrintTicket為您的使用該檔所建立的應用程式將Unknown具有做為PhotoPrintingIntent屬性的值。If some other PrintTicket producing application has created a PrintTicket document that sets the photo printing intent feature to an unrecognized option (that is, an option that is not defined in the Print Schema, then a PrintTicket object in your application that is constructed with that document will have Unknown as the value of the PhotoPrintingIntent property.

PrintCapabilities PrintTicket 雖然無法繼承PrintCapabilities和類別, 但是您可以擴充列印架構, 以辨識或類別中未納入的列印裝置功能。 PrintTicketAlthough the PrintTicket and PrintCapabilities classes cannot be inherited, you can extend the Print Schema to recognize print device features that are not accounted for in the PrintTicket or PrintCapabilities classes. 如需詳細資訊,請參閱如何:擴充列印架構, 並建立新的列印系統類別。For more information, see How to: Extend the Print Schema and Create New Print System Classes.
