virtual |
Get number of GCPs.
This method is the same as the C function GDALGetGCPCount().
Reimplemented from GDALPamDataset.
|
virtual |
Get output projection for GCPs.
This method is the same as the C function GDALGetGCPProjection().
The projection string follows the normal rules from GetProjectionRef().
Reimplemented from GDALPamDataset.
|
virtual |
Fetch GCPs.
This method is the same as the C function GDALGetGCPs().
Reimplemented from GDALPamDataset.
|
virtual |
Fetch the affine transformation coefficients.
Fetches the coefficients for transforming between pixel/line (P,L) raster space, and projection coordinates (Xp,Yp) space.
In a north up image, padfTransform[1] is the pixel width, and padfTransform[5] is the pixel height. The upper left corner of the upper left pixel is at position (padfTransform[0],padfTransform[3]).
The default transform is (0,1,0,0,0,1) and should be returned even when a CE_Failure error is returned, such as for formats that don't support transformation to projection coordinates.
This method does the same thing as the C GDALGetGeoTransform() function.
padfTransform | an existing six double buffer into which the transformation will be placed. |
Reimplemented from GDALPamDataset.
|
virtual |
Fetch metadata.
The returned string list is owned by the object, and may change at any time. It is formatted as a "Name=value" list with the last pointer value being NULL. Use 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 GDALPamDataset.
|
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 GDALPamDataset.
|
virtual |
Fetch the projection definition string for this dataset.
Same as the C function GDALGetProjectionRef().
The returned string defines the projection coordinate system of the image in OpenGIS WKT format. It should be suitable for use with the OGRSpatialReference class.
When a projection definition is not available an empty (but not NULL) string is returned.
Reimplemented from GDALPamDataset.
|
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 GDALPamDataset.
|
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. |
Reimplemented from GDALPamDataset.
