Purpose. Set/get the /MK /BG (background), /MK /BC (border), and /DA text colors of the most recently created field — see the chapter-level cursor note above.

Description. Each setter both writes the color to the actual field (SetFieldColorH(FCurrentFieldHandle, ...)) and caches it in a separate shadow field (FCurFieldBackColor/BorderColor/TextColor), per an explicit DIFF comment ("also stores state") — the getters read back from these cached shadow fields, not by re-querying the field itself, so if the field's color were somehow changed through another path (e.g. pdfSetFieldColor on the same handle), these getters would report the stale cached value rather than the field's current true color.

Parameters.

Return value. Getters: the cached color; 0 if IPDF invalid or no field has been created yet. Setters: True if IPDF valid.

See also. pdfGetFieldColor (the explicit- handle equivalent, for targeting any field).
