IXpsOMGradientBrush::GetTransform method

Gets a pointer to the IXpsOMMatrixTransform interface that contains the resolved matrix transform for the brush.

Syntax

HRESULT GetTransform(
  [out, retval] IXpsOMMatrixTransform **transform
);

Parameters

  • transform [out, retval]
    A pointer to the IXpsOMMatrixTransform interface that contains the resolved matrix transform for the brush. If the transform has not been set, a NULL pointer is returned.

    The value that is returned in this parameter depends on which method has been most recently called to set the transform.

    Most recent method called Object that is returned in transform

    SetTransformLocal

    The local transform that is set by SetTransformLocal.

    SetTransformLookup

    The shared transform that is retrieved, with a lookup key that matches the key set by SetTransformLookup, from the resource directory.

    Neither SetTransformLocal nor SetTransformLookup has been called yet.

    NULL pointer.

     

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the table that follows. For information about XPS document API return values that are not listed in this table, see XPS Document Errors.

Return code Description
S_OK

The method succeeded.

E_POINTER

transform is NULL.

XPS_E_LOOKUP_INVALID_TYPE

The lookup key name set by SetStrokeBrushLookup references an object that is not a brush.

XPS_E_LOOKUP_NOT_FOUND

No object could be found with a key name that matched the lookup value.

No object could be found with a key name that matched the value passed in lookup.

 

Remarks

The transform determines how the gradient is transformed. The visible part of the gradient that is ultimately rendered in the image is determined by the path, stroke, or glyph that is using the gradient brush.
