BOOL32 __stdcall pdfGetDeviceNAttributes(void* IAttributes, TDeviceNAttributes* Attributes);

Delphi

function pdfGetDeviceNAttributes(IAttributes: Pointer; var Attributes: TDeviceNAttributes): LongBool; stdcall;

Purpose. Read a DeviceN color space's /Attributes dict (process- colorant count and, per the struct shape, a process-color-space sub-reference) through the object-descriptor handle minted by pdfGetColorSpaceObj/Ex (Colors and Color Spaces, odDevNAttr).

Description. Attributes.IProcessColorSpace is always left nil — only ProcessColorantsCount is genuinely filled from GetDeviceNAttrH; the process-color-space sub-object handle the struct shape implies (for reading the /Process /ColorSpace entry) is never minted, so a caller cannot drill further into the process color space through this call.

Parameters.

Parameter	Description
`IAttributes`	A DeviceN-attributes object handle from `pdfGetColorSpaceObj`.
`Attributes`	Output: `ProcessColorantsCount` (filled); `IProcessColorSpace` (always `nil`).

Return value. True if IAttributes resolves; False otherwise.
