Member Function Documentation
| bool a2dIOHandlerGDSOut::CanSave | ( | const wxObject * | obj = NULL |
) | [virtual] |
Should return true if the handler can write this document to a stream.
Mostly implemented by simply returning true if the handler can indeed do this job. Understand that a a2dDocument itself is useless for storing data, so it needs to be casted internal to a specific a2dDocument.
- Parameters:
-
obj pointer to object to save, normally a document.
Implements a2dIOHandlerStrOut.
| bool a2dIOHandlerGDSOut::Save | ( | a2dDocumentOutputStream & | stream, | |
| const wxObject * | obj | |||
| ) | [virtual] |
Override to write to the stream and store (part of) of the document contents in the stream.
Understand that a a2dDocument itself is useless for storing data, so it needs to be casted internal to a specific a2dDocument.
- Parameters:
-
stream the open stream to which the object needs to be saved obj object to save into stream, needs to be casted to the right one internal.
Implements a2dIOHandlerStrOut.
| void a2dIOHandlerGDSOut::double2gds | ( | unsigned char | fb[] | ) | [protected] |
convert a machine real to a gdsii real
convert a machine double to gds double usage: void double2gds( fb ) input arguments : unsigned char fb[] 8byte array with machine double output arguments : unsigned char fb[] 8byte array with gds double
Important note: The number of mantissa bit in VAX representation is one less than the number of mantissa bits in GDSII representation. This routine is not able to generate the last 2 bits of the GDSII representation exactly. There does not exist a general solution for this problem!! In order to overcome the single problem that we are aware of, the UNITs record that is sometimes compared to a UNITs record, the solution is hard coded in this routine. The last 8 bits of a number representing 1E-9 result in 53, but should produce 51 (See GDSII documentation of UNIT record and the given example of it).
!! The same story holds for APOLLO and wxBIG_ENDIAN, but even worse. 1E-3 results in F0 for the last 8 bits instead of EF. Also corrected.
