Basic Types Structures

These types and structures are defined in PrSDKTypes.h and PrSDKStructs.h, and are used throughout the Premiere API.

Premiere defines cross-platform types for convenience when developing plugins for both Windows and Mac OS.

Name

Description

prColor

An unsigned 32-bit integer that stores an RGB color.

This type is useful for the 8-bpc colors retrieved by the color picker in a video effect or transition.

Color channels are stored as BGRA, in order of increasing memory address from left to right.

prWnd

A Windows HWND or Mac OS NSView*

prParentWnd

A Windows HWND or Mac OS NSWindow*

prOffscreen

A Windows HDC

prRect

A Windows RECT or Mac OS Rect.

Use the utility function prSetRect to set the dimensions of a prRect struct.

This should be used because Mac OS Rect members have a different ordering than Windows RECT members.

prFloatRect

 

typedef struct {
  float left;
  float top;
  float right;
  float bottom;
} prFloatRect;

prRgn

A Windows HRGN

prPoint, LongPoint

 

typedef struct {
  csSDK_int32 x;
  csSDK_int32 y;
} prPoint, LongPoint;

LongPoint is deprecated, but still used for a couple of Bottleneck callbacks

prFPoint

 

typedef struct {
  double x;
  double y;
} prFPoint64;

prPixel

(Deprecated)

prPixelAspectRatio

(Deprecated)

PPix, *PPixPtr, **PPixHand

Holds a video frame or field, and contains related attributes such as pixel aspect ratio and pixel format.

Manipulate PPixs using the PPix Suite, never directly.

TDB_TimeRecord

A time database record representing a time value in the context of a video frame rate.

typedef struct {
  TDB_Time       value;
  TDB_TimeScale  scale;
  TDB_SampSize   sampleSize;
} TDB_TimeRecord;

prBool

Can be either kPrTrue or kPrFalse

PrMemoryPtr, *PrMemoryHandle

A char*

PrTimelineID, PrClipID

A 32-bit signed integer.

prUTF8Char

An 8-bit unsigned integer.

PrSDKString

An opaque data type that should be accessed using the new String Suite.

PrParam

Used for exporter parameters

struct PrParam
{
  PrParamType mType;
  union
  {
    csSDK_int8   mInt8;
    csSDK_int16  mInt16;
    csSDK_int32  mInt32;
    csSDK_int64  mInt64;
    float        mFloat32;
    double       mFloat64;
    csSDK_uint8  mBool;
    prFPoint64   mPoint;
    prPluginID   mGuid;
    PrMemoryPtr  mMemoryPtr;
  };
};

enum PrParamType
{
  kPrParamType_Int8 = 1,
  kPrParamType_Int16,
  kPrParamType_Int32,
  kPrParamType_Int64,
  kPrParamType_Float32,
  kPrParamType_Float64,
  kPrParamType_Bool,
  kPrParamType_Point,
  kPrParamType_Guid,
  kPrParamType_PrMemoryPtr
};

prDateStamp

Used in by importers in imFileAttributesRec.creationDateStamp.

typedef struct
{
  csSDK_int32  day;
  csSDK_int32  month;
  csSDK_int32  year;
  csSDK_int32  hours;
  csSDK_int32  minutes;
  double       seconds;
} prDateStamp;
