Detailed Description

Filter to mosaic images.

The coordinate transformation between resulting image and each input stage is computed using georeference as specified in constructor, or georeference from specified reference image, along with the georeference from the input stage. An optional transformation accuracy may be specified via SetAccuracy() to allow use of efficient affine transformation if appropriate. Note that source images will not be processed "sequentially", and the sections specified in PullBegin for the source will overlap. It is recommended that a suitable caching filter be placed ahead of this filter if the input requires significant computation or sequential iteration.

	)

Construct to match specified reference image.

Parameters:

Member Function Documentation

void SPATMOD::IMAGE::FILTER_MOSAIC::SetAccuracy

(

double

accuracy

)

[inline]

Set transformation accuracy in source cells.

If within the specified accuracy, a fast affine transformation will be used for computation. If used, must be done before Initialize(). Default accuracy is .5 cells.

Parameters:

accuracy

Transformation accuracy in source cells.

ERRVALUE SPATMOD::IMAGE::FILTER_MOSAIC::SetPixelTestClosest

(

const PIXEL &

PixelTestClosest

)

Set pixel for OVERLAPMETHOD_ClosestToSpecified.

If not specified, the center of the valid data range will be used by default.

Parameters:

PixelTestClosest

Pixel value, must have same properties as image itself
