class gsdtoolsui.tooldescriptors.Ras2vecDescriptor(cwd=None, env=None, stdout_handler=None, stderr_handler=None)

exectools.ToolDescriptor

Parameters:

• cwd – program working directory
• env – environment dictionary
• envmerge – if set to True (default) it is the env dictionaty is used to update the system environment
• stdout_handler – OutputHandler for the stdout of the tool
• stderr_handler – +OutputHandler* for the stderr of the tool

exectools.BaseOutputHandler

abspath = None

Store absolute path in bounding box feature description.

cmdline(*args, **kwargs)

corners = None

Generate markers for bounding box corners.

gcps = None

Generate an additional layer for GCPs.

class gsdtoolsui.tooldescriptors.StatsDescriptor(cwd=None, env=None, stdout_handler=None, stderr_handler=None)

Bases: gsdview.gdalbackend.gdalexectools.BaseGdalToolDescriptor

Descriptor for gsdstats tool.

exectools.ToolDescriptor

Parameters:

• cwd – program working directory
• env – environment dictionary
• envmerge – if set to True (default) it is the env dictionaty is used to update the system environment
• stdout_handler – OutputHandler for the stdout of the tool
• stderr_handler – OutputHandler for the stderr of the tool

exectools.BaseOutputHandler

approxok = None

Allow approximate statistics computation.

If set then statistics may be computed based on overviews or a subset of all tiles (default: False)

band = None

Compute statistics for a specific raster band.

Default: all bands are precessed.

cmdline(*args, **kwargs)

hist

Histogram request.

Histogram request objects allow to specifie parameters for historams computarion or disable histogram computation at all.

See also

gsdtools.stats.HistogramRequest.

If set to a non null value the histogram computation is enabled:

desctiptot.hist = True

the above code is equivalent to:

desctiptot.hist.computehistogram = True

Use histogram request object attributes to speficy custom parameters for historam comutation:

desctiptot.hist.hmin = - 0.5
desctiptot.hist.hmax = 3000.5
desctiptot.hist.nbuckets = 101
desctiptot.hist.include_out_of_range = True

To disable histocram computation set it hist to False:

desctiptot.hist = False

Setting hist to None disable histogram computation and perform a fiull reset of the histogram requast object:

desctiptot.hist = None

minmaxonly = None

Only print minimum and maximum on the same line

nostats = None

Disable statistics computation (default: False)

outfile = None

Write results to FILE.

quiet = None

Suppress progress messages.

srcwin = None

Specify source window in image coordinates.

Default: the entire image is processed.
