Description

(GRASS Shell Script)

d.out.file uses d.save, the GRASS PNG or PostScript driver, and gdal_translate to export the currently selected X display monitor to a graphics file of several formats. Output image size can be set prior to export.

PNG and PPM formats are supported directly by the GRASS PNG driver and PostScript output is supported directly by the GRASS PS driver.

TIFF, JPEG, and BMP formats are supported by using gdal_translate on PPM format files produced by the GRASS PNG driver. Different levels of compression/quality are supported for JPEG files.

Graphic files are exported to the user's current working directory by default, but different paths may be specified in the output field.

EPS files are not compatible with d.frame, as it is not possible to nest encapsulation. Only the first frame will be drawn. In these cases it is recommended to output to regular PostScript format and then use a utility like ps2epsi to convert to an EPS file. Output from this module using the regular PostScript format may contain subframes.
