Member Function Documentation
| int SML::RASTEROBJECT::Flush |
( |
|
) |
|
Flush the internal buffers.
| int SML::RASTEROBJECT::GetCurCol |
( |
|
) |
const |
| int SML::RASTEROBJECT::GetCurLin |
( |
|
) |
const |
| DEPRECATED int SML::RASTEROBJECT::GetDataType |
( |
|
) |
const |
Get the data type (RVCTYPE_Xxx).
Get a pointer to the RVC::RASTER interface class.
Do NOT free this pointer. It will be destroyed when the SML::OBJECT is destroyed. The interface returned is Attached to the object but may or may not be open. If the SML::BOJECT does not refer to any existing real object, this method will return NULL.
| bool SML::RASTEROBJECT::GetNullKnown |
( |
|
) |
const |
Returns true if the Null value is known (should be named IsNullKnown).
| double SML::RASTEROBJECT::GetNullValue |
( |
|
) |
const |
Return the raster's NULL value as a double return value undefined if the raster doesn't have a NULL value.
| DEPRECATED int SML::RASTEROBJECT::GetNumBits |
( |
|
) |
const |
Returns the number of bits/cell.
| int SML::RASTEROBJECT::GetNumCols |
( |
|
) |
const |
Returns the number of raster columns.
| int SML::RASTEROBJECT::GetNumLins |
( |
|
) |
const |
Returns the number of raster lines.
| bool SML::RASTEROBJECT::GetUseNull |
( |
|
) |
const |
Returns true if the NULL cells are being treated as NULL Returns false if NULL cells are being treated as normal values.
| void SML::RASTEROBJECT::InvalidateImageStats |
( |
|
) |
|
Force a re-read of the histogram the next time GetImageStats() is called.
| int SML::RASTEROBJECT::ReadCell |
( |
int |
lin, |
|
|
int |
col, |
|
|
double * |
pval | |
|
) |
| | |
Read a single raster cell.
| double SML::RASTEROBJECT::ReadCell |
( |
int |
lin, |
|
|
int |
col | |
|
) |
| | |
Reads the cell value at a given location Sets ErrorCode if fatal error.
| void SML::RASTEROBJECT::SetCurCol |
( |
int |
col |
) |
|
Set the current column (used by foreach loops).
| void SML::RASTEROBJECT::SetCurLin |
( |
int |
lin |
) |
|
Set the current line (used by foreach loops).
| void SML::RASTEROBJECT::SetHistoRead |
( |
bool |
known |
) |
|
Set whether or not histogram has been read.
| void SML::RASTEROBJECT::SetInterface |
( |
RVC::RASTER * |
obj |
) |
|
Set a pointer to the RVC::RASTER interface class.
After setting the interface, the SML::OBJECT "owns" it and will delete it in its own destructor. Do not under any circumstances pass a pointer to an local variable that will go out of scope. Since SML::OBJECT is implemented in rvcsys.dll it does not have have access to the copy constructor.
| void SML::RASTEROBJECT::SetMaxValue |
( |
double |
val |
) |
|
| void SML::RASTEROBJECT::SetMinValue |
( |
double |
val |
) |
|
| void SML::RASTEROBJECT::SetNullKnown |
( |
bool |
known |
) |
|
| void SML::RASTEROBJECT::SetNullValue |
( |
double |
val |
) |
|
| void SML::RASTEROBJECT::SetupRaster |
( |
|
) |
|
| void SML::RASTEROBJECT::SetUseNull |
( |
bool |
use |
) |
|
| int SML::RASTEROBJECT::WriteCell |
( |
int |
lin, |
|
|
int |
col, |
|
|
double |
val | |
|
) |
| | |
Write a single raster cell.
| int SML::RASTEROBJECT::WriteSpan |
( |
int |
lin, |
|
|
int |
startcol, |
|
|
int |
endcol, |
|
|
double |
val | |
|
) |
| | |
Write a span of raster cells all the same value.
