double VRTSourcedRasterBand::GetMaximum | ( | int * | pbSuccess = NULL | ) | [virtual] |
Fetch the maximum value for this band.
For file formats that don't know this intrinsically, the maximum supported value for the data type will generally be returned.
This method is the same as the C function GDALGetRasterMaximum().
pbSuccess | pointer to a boolean to use to indicate if the returned value is a tight maximum or not. May be NULL (default). |
Reimplemented from GDALRasterBand.
References CPLAtofM(), GetMetadataItem(), GDALRasterBand::GetXSize(), and GDALRasterBand::GetYSize().
char ** VRTSourcedRasterBand::GetMetadata | ( | const char * | pszDomain = "" | ) | [virtual] |
Fetch metadata.
The returned string list is owned by the object, and may change at any time. It is formated as a "Name=value" list with the last pointer value being NULL. Use the the CPL StringList functions such as CSLFetchNameValue() to manipulate it.
Note that relatively few formats return any metadata at this time.
This method does the same thing as the C function GDALGetMetadata().
pszDomain | the domain of interest. Use "" or NULL for the default domain. |
Reimplemented from GDALMajorObject.
const char * VRTSourcedRasterBand::GetMetadataItem | ( | const char * | pszName, |
const char * | pszDomain = "" |
||
) | [virtual] |
Fetch single metadata item.
The C function GDALGetMetadataItem() does the same thing as this method.
pszName | the key for the metadata item to fetch. |
pszDomain | the domain to fetch for, use NULL for the default domain. |
Reimplemented from GDALMajorObject.
References GDALInvGeoTransform(), GDALRasterBand::GetDataset(), GDALRasterBand::GetXSize(), and GDALRasterBand::GetYSize().

double VRTSourcedRasterBand::GetMinimum | ( | int * | pbSuccess = NULL | ) | [virtual] |
Fetch the minimum value for this band.
For file formats that don't know this intrinsically, the minimum supported value for the data type will generally be returned.
This method is the same as the C function GDALGetRasterMinimum().
pbSuccess | pointer to a boolean to use to indicate if the returned value is a tight minimum or not. May be NULL (default). |
Reimplemented from GDALRasterBand.
References CPLAtofM(), GetMetadataItem(), GDALRasterBand::GetXSize(), and GDALRasterBand::GetYSize().
CPLErr VRTSourcedRasterBand::SetMetadata | ( | char ** | papszMetadataIn, |
const char * | pszDomain = "" |
||
) | [virtual] |
Set metadata.
The C function GDALSetMetadata() does the same thing as this method.
papszMetadataIn | the metadata in name=value string list format to apply. |
pszDomain | the domain of interest. Use "" or NULL for the default domain. |
Reimplemented from VRTRasterBand.

CPLErr VRTSourcedRasterBand::SetMetadataItem | ( | const char * | pszName, |
const char * | pszValue, | ||
const char * | pszDomain = "" |
||
) | [virtual] |
Set single metadata item.
The C function GDALSetMetadataItem() does the same thing as this method.
pszName | the key for the metadata item to fetch. |
pszValue | the value to assign to the key. |
pszDomain | the domain to set within, use NULL for the default domain. |
