WICImageParameters structure (wincodec.h)

This defines parameters that you can use to override the default parameters normally used when encoding an image.

Syntax

typedef struct WICImageParameters {
  D2D1_PIXEL_FORMAT PixelFormat;
  FLOAT             DpiX;
  FLOAT             DpiY;
  FLOAT             Top;
  FLOAT             Left;
  UINT32            PixelWidth;
  UINT32            PixelHeight;
} WICImageParameters;

Members

PixelFormat

The pixel format to which the image is processed before it is written to the encoder.

DpiX

The DPI in the x dimension.

DpiY

The DPI in the y dimension.

Top

The top corner in pixels of the image space to be encoded to the destination.

Left

The left corner in pixels of the image space to be encoded to the destination.

PixelWidth

The width in pixels of the part of the image to write.

PixelHeight

The height in pixels of the part of the image to write.

Remarks

If this parameter is not passed to the encoding API, the encoder uses these settings.

• A pixel format of (DXGI_FORMAT_B8G8R8A8_UNORM, D2D1_ALPHA_MODE_PREMULTIPLIED).
• An x and y DPI of 96.
• The entire image bounds will be used for encoding.
