This method creates an in-memory bitmap image object from another image object.

Syntax 

HRESULT CreateBitmapFromImage(
  IImage*			
image,
  OPTIONAL UINT	
width,
  OPTIONAL UINT	
height,
  OPTIONAL PixelFormatID 
pixelFormat,
  InterpolationHint
hints,
  IBitmapImage**		 
bitmap
);

Parameters

image

[in] A pointer to an IImageinterface containing the original image data.

width

[in] A UINT value that specifies the width, in pixels, of the new bitmap image.

Set this value to 0 create a new bitmap image that is the same height as the source image.

height

[in] A UINT value that specifies the height, in pixels, of the new bitmap image.

Set this value to 0 create a new bitmap image that is the same width as the source image.

pixelFormat

[in] A PixelFormatID value that specifies the numerical format of the pixels in the image. For more information, see PixelFormat Values.

Set this value to PixelFormatDontCare to create a new bitmap image that has the same pixel format as the source image.

hints

[in] An InterpolationHintenumeration value that specifies the interpolation technique that this method should use when resizing the bitmap.

bitmap

[out] A pointer to the resulting IBitmapImageinterface pointer.

Use the interface to access the bitmap image created by this method.

Return Value

If successful, this method returns S_OK.

This method may return E_POINTER if it fails.

Remarks

This method is convenient for converting a bitmap image object of one pixel format into another object of a different pixel format.

Requirements

Header imaging.h
Library Imaging.lib
Windows Embedded CE Windows CE 5.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
