use of ini.trakem2.display.VectorData in project TrakEM2 by trakem2.

the class AlignTask method createTransformPropertiesTable.

/**
 * Creates a map only for visible patches that intersect vdata.
 *  @param src_vdata represents the VectorData instances in original form, of the original project and layer set.
 *  @param tgt_vdata if not null, it must have the same size as src_data and their elements correspond one-to-one (as in, tgt element a clone of src element at the same index).
 *  @param lids_to_operate The id of the layers on which any operation will be done
 *  tgt_data enables transformVectorData to apply the transforms to copies of the src_vdata in another project.
