ExportRaster

globalmapper.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[source]

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 GetProjection function. You can change the view projection, and thus the export projection, by calling the SetProjection function.

Parameters:

  • aFilename (str) – Name of new file to create

  • aFormat (GM_RasterExportFormat_t32) – Format to export

  • aLayer (GM_LayerHandle_t32) – Layer to export or gm.NULL for all

  • aWorldBounds (GM_Rectangle_t) – World bounds to export or None for all

  • aPixelWidth (sint32) – Width in pixels of new image

  • aPixelHeight (sint32) – Height in pixels of new image

  • aFlags (GM_RasterExportFlags_t32) – Export flags

Returns:

Error Code

Return type:

GM_Error_t32

Example

The following is an example of ExportRaster.:

gm.ExportRaster(target_directory + "merged_drg.jpg", gm.GM_Export_JPG, 0x0, None, width, height, gm.GM_ExportFlags_GenWorldFile + gm.GM_ExportFlags_GenPRJFile)
