class gsdview.gdalbackend.modelitems.BandItem(band, **kwargs)[source]¶

Bases: gsdview.gdalbackend.modelitems.MajorObjectItem

Raster band item.

This class implements both the QStandardItem and the gdal.Band interface.

It also as attatched a graphics scene containing a GdalGraphicsItem

GetOverview(index)[source]¶

GetOverviewCount()[source]¶

close()[source]¶

cmapper[source]¶: Coordinate mapper object.

footprint()[source]¶

graphicsitem = None¶: graphics item representing the raster band

iconfile = <PyQt4.QtGui.QIcon object at 0x441bb90>¶

scene = None¶: graphics scene associated to the raster band

class gsdview.gdalbackend.modelitems.CachedDatasetItem(filename, mode=1, **kwargs)[source]¶

Bases: gsdview.gdalbackend.modelitems.DatasetItem

CACHEDIR = '/home/antonio/.gsdview/cache'¶

GetMetadata(domain='')[source]¶

GetMetadataItem(name, domain='')[source]¶

GetMetadata_Dict(domain='')[source]¶

GetMetadata_List(domain='')[source]¶

close()[source]¶

cmapper = None¶: coordinate mapper

filename = None¶: dataset filename

graphicsitem = None¶: graphics item representing the dataset

reopen()[source]¶

scene = None¶: graphics scene associated to the item

vrtfilename = None¶: filename of the cached virtual dataset

class gsdview.gdalbackend.modelitems.DatasetItem(filename, mode=0, **kwargs)[source]¶

Bases: gsdview.gdalbackend.modelitems.MajorObjectItem

Dataset item

This class implements both the QStandardItem and the gdal.Dataset interface.

GetRasterBand(index)[source]¶

GetSubDatasets()[source]¶

close()[source]¶

cmapper = None¶: coordiante mapper

filename = None¶: dataset filename

footprint()[source]¶

Return the dataset geographic footprint as a QPolygonF.

The geographic footprint is a QPolygonF containing the four vertices of the image in geographic coordinates. If no geographic info is available in the dataset None is returned.
