Defined Types

Number Format

typedef enum _DPSNumberFormat {
#ifdef __BIG_ENDIAN__
    dps_float = 48,
    dps_long = 0,
    dps_short = 32
#else
    dps_float = 48+128,
    dps_long = 0+128,
    dps_short = 32+128
#endif
} DPSNumberFormat;

Other permitted values are:

• For 32-bit fixed-point numbers, use dps_long plus the number of bits in the fractional part.
• For 16-bit fixed-point numbers, use dps_short plus the number of bits in the fractional part.

NSBackingStoreType

typedef enum _NSBackingStoreType {
    NSBackingStoreRetained,
    NSBackingStoreNonretained,
    NSBackingStoreBuffered
} NSBackingStoreType;

Backing store types.

Compositing Operations

typedef enum _NSCompositingOperation {
    NSCompositeClear,
    NSCompositeCopy,
    NSCompositeSourceOver,
    NSCompositeSourceIn,
    NSCompositeSourceOut,
    NSCompositeSourceAtop,
    NSCompositeDestinationOver,
    NSCompositeDestinationIn,
    NSCompositeDestinationOut,
    NSCompositeDestinationAtop,
    NSCompositeXOR,
    NSCompositePlusDarker,
    NSCompositeHighlight,
    NSCompositePlusLighter
} NSCompositingOperation;

NSWindowOrderingMode

typedef enum _NSWindowOrderingMode {
    NSWindowAbove,
    NSWindowBelow,
    NSWindowOut
} NSWindowOrderingMode;

User Path Operators

typedef unsigned char DPSUserPathOp;
enum {
    dps_setbbox,
    dps_moveto,
    dps_rmoveto,
    dps_lineto,
    dps_rlineto,
    dps_curveto,
    dps_rcurveto,
    dps_arc,
    dps_arcn,
    dps_arct,
    dps_closepath,
    dps_ucache
};

User path operators. These constants define the operator numbers used to construct the operator array parameter of DPSDoUserPath.

User Path Actions

typedef enum _DPSUserPathAction {
    dps_uappend,
    dps_ufill,
    dps_ueofill,
    ps_ustroke,
    dps_ustrokepath,
    dps_inufill,
    dps_inueofill,
    dps_inustroke,
    dps_def,
    dps_put
} DPSUserPathAction;

User path actions. These constants define the action of a DPSDoUserPath. In addition to the actions defined here, any other system name index may be used. See the PostScript Language Reference Manual, Second Edition, by Adobe Systems Incorporated, for a detailed list of system name indexes.

Enumerations

Alpha Values

enum {
    NSAlphaEqualToData,
    NSAlphaAlwaysOne
};

Null Object

enum {
    DPSNullObject
};

User object representing the PostScript null object.

Symbolic Constants

DPS_OPENSTEP_ERROR_BASE

Error code base.
