Function Documentation

ObitImageSel* newObitImageSel (  gchar *  name  )

Public: Constructor. Returns: pointer to object created.

ObitFArray* ObitImageSelBuffer (  ObitFArray *  buffer, ObitImageDesc *  desc, ObitImageSel *  sel )

Public: Create/resize buffer for image? Parameters: buffer  Preexisting buffer or NULL if none desc  Pointer input descriptor. sel  Image selector. Returns: size in floats needed for I/O.

void ObitImageSelClassInit (  void   )

Public: Class initializer.

void ObitImageSelClear (  gpointer  inn  )

Private: Deallocate members. Does (recursive) deallocation of parent class members. Parameters: inn  Pointer to the object to deallocate.

ObitImageSel* ObitImageSelCopy (  ObitImageSel *  in, ObitImageSel *  out, ObitErr *  err )

Public: Copy ImageSel. Parameters: in  Pointer to object to be copied. out  Pointer to object to be written. If NULL then a new structure is created. err  ObitErr error stack Returns: Pointer to new object.

void ObitImageSelDefault (  ObitImageDesc *  in, ObitImageSel *  sel )

Public: Enforces defaults in inaxes, blc, trc. Also indexes structure. Parameters: in  Pointer to descriptor. sel  Image selector, blc, trc members changed if needed.

gconstpointer ObitImageSelGetClass (  void   )

Public: Return class pointer. Initializes class if needed on first call. Returns: pointer to the class structure.

void ObitImageSelInit (  gpointer  inn  )

Private: Initialize newly instantiated object. Does (recursive) initialization of base class members before this class. Parameters: inn  Pointer to the object to initialize.

void ObitImageSelSetDesc (  ObitImageDesc *  in, ObitImageSel *  sel, ObitImageDesc *  out, ObitErr *  err )

Public: Applies selection to a Descriptor. Parameters: in  Pointer to input descriptor. sel  Image selector, blc, trc members changed if needed. out  Pointer to output descriptor. err  Obit error stack
