Member Function Documentation

virtual signed int IImageUtil::AskInterface ( const BGUID *  piid, IRoot **  ppr  )

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Returns

S_OK if the interface is supported. E_FAIL if it is not.

Implements IRoot.

virtual signed int IImageUtil::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

Implements IRoot.

virtual signed int IImageUtil::ImageAlloc ( VOLVISIMAGE *  im )

pure virtual

Allocates the VOLVISIMAGE::Data buffer based upon the parameters specified in the rest of the structure.

Parameters

im	VOLVISIMAGE to validate.

virtual signed int IImageUtil::ImageBytePerPixel ( unsigned int *  pl, ENUM_IMAGE_TYPE  type  )

pure virtual

pl will receive the number of bytes per pixel for this image type.

Parameters

pl	destination parameter.
type	Image type in question.

virtual signed int IImageUtil::ImageCopy ( VOLVISIMAGE *  dst, VOLVISIMAGE *  src  )

pure virtual

Copies an image. The dst image is allocated by this function.

Parameters

dst	Structure which recieves the new image params.
src	Stricture describing the input image.

virtual signed int IImageUtil::ImageDataSize ( unsigned int *  pl, VOLVISIMAGE *  im  )

pure virtual

pl will receive the number of bytes necessary to store the information in this image.

Parameters

pl	destination parameter.
im	The Image in question.

virtual signed int IImageUtil::ImageFragmentRowDataOffset ( unsigned int *  pl, const VOLVISIMAGE *  im, ENUM_CLUSTER_PARAM  e, unsigned int  FragemntId, unsigned int  lRow  )

pure virtual

Returns the offset into the data buffer for the fragment specified in the current clustering environment.

Parameters

pl	destination parameter.
im	The full output image.
e	The parameters for clustering.
FragemntId	The fragment rendered.
lRow	The row to get in this fragment.

virtual signed int IImageUtil::ImageFree ( VOLVISIMAGE *  im )

pure virtual

Frees the VOLVISIMAGE::Data buffer.

Parameters

im	image to invalidate.

virtual signed int IImageUtil::ImageSmooth ( VOLVISIMAGE *  dst, VOLVISIMAGE *  src  )

pure virtual

Smooths an image, reducing the number of jaggies. This is called automatically by all engines except the Thin MIP/MPR engine (overridable by a render flag).

Parameters

dst	Destination image. The data buffer is allocated by this function.
src	Source image.

virtual signed int IImageUtil::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.

Implements IRoot.
