WICJpegIndexingOptions enumeration (wincodec.h)

Specifies the options for indexing a JPEG image.

Syntax

typedef enum WICJpegIndexingOptions {
  WICJpegIndexingOptionsGenerateOnDemand = 0,
  WICJpegIndexingOptionsGenerateOnLoad = 0x1,
  WICJpegIndexingOptions_FORCE_DWORD = 0x7fffffff
} ;

Constants

WICJpegIndexingOptionsGenerateOnDemand Value: 0 Index generation is deferred until IWICBitmapSource::CopyPixels is called on the image.
WICJpegIndexingOptionsGenerateOnLoad Value: 0x1 Index generation is performed when the when the image is initially loaded.
WICJpegIndexingOptions_FORCE_DWORD Value: 0x7fffffff Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
