This feature is being deprecated for this release. Refer to this component: Windows Imaging Component.

This method lets an application create a decoded image object from a file.

Syntax

HRESULT CreateImageFromFile(
  const WCHAR* filename,
  IImage** image
);

Parameters

  • filename
    [in] A WCHAR array containing the name of the source file.
  • image
    [out] A pointer to the resulting IImage interface pointer.

Return Value

If successful, this method returns S_OK.

This method may return E_POINTER if it fails.

Remarks

When the decoded image object is created, it only keeps a reference to the external data source and does not immediately decode the image. The decoded image opens the file in read-only mode and allows shared-read access to it.

Be aware that decoded image objects are read-only. In particular, you cannot modify the image data. However, you can display it onto a destination graphics context or push its data into an image sink. For more information, see IImage.
