globalmapper.ExportRaster
=========================

.. currentmodule:: globalmapper
.. py:function:: ExportRaster (str aFilename, GM_RasterExportFormat_t32 aFormat, GM_LayerHandle_t32 aLayer, GM_Rectangle_t aWorldBounds, sint32 aPixelWidth, sint32 aPixelHeight, GM_RasterExportFlags_t32 aFlags) -> GM_Error_t32

    Exports one or more layers to a new raster file. If gm.NULL is passed for the layer handle, all loaded layers will be
    saved to the new raster file, otherwise only the specified layer will be exported. If None is provided for the world
    bounds, all available data will be exported, otherwise only data within the specified bounds will be exported.

    The new raster file create will be in the current view projection as returned by the
    :doc:`GetProjection function<../measure/globalmapper.GetProjection>`. You can change the view projection, and thus
    the export projection, by calling the :doc:`SetProjection function<../measure/globalmapper.SetProjection>`.

    :param str aFilename: Name of new file to create
    :param GM_RasterExportFormat_t32 aFormat: Format to export
    :param GM_LayerHandle_t32 aLayer: Layer to export or gm.NULL for all
    :param GM_Rectangle_t aWorldBounds: World bounds to export or None for all
    :param sint32 aPixelWidth: Width in pixels of new image
    :param sint32 aPixelHeight: Height in pixels of new image
    :param GM_RasterExportFlags_t32 aFlags: Export flags
    :returns: Error Code
    :rtype: GM_Error_t32
