The current ​library is available in Python3. Older versions in Python2 ​and IDL are available, but no longer actively maintained.
  
 The drizzling library uses a strategy where the surface of pixel intersection is computed as presented in Appendix A of Paradis et al., 2012, A&A, 543, 103. This method allows fast ingestion and guarantees the photometric accuracy of the transformation with minimal data loss during the transformation from HEALPix ​ to local WCS FITS. The drizzling library uses a strategy where the surface of pixel intersection is computed as presented in Appendix A of Paradis et al., 2012, A&A, 543, 103.

-**NEW** ​CADE now offers a web interface to the drizzling software library called **drizzweb**. This allows the user to reproject data from HEALPix to local WCS FITS format using CADE's computing resources.
