bool ImageExporter::exportImage ( QString  url )

slot

Exports an image with the defined settings.

Parameters

url	URL of the exported image

Returns

false if the URL was a network location and uploading to the network location failed

void ImageExporter::setLegendProperties ( Legend::LEGEND_TYPE  type, Legend::LEGEND_ORIENTATION  orientation, Legend::LEGEND_POSITION  position, int  alpha = 160, bool  include = true  )

slot

Set the legend properties.

Parameters

type	Legend type. (See enum LEGEND_TYPE in legend.h)
orientation	Legend orientation. (See LEGEND_ORIENTATION in legend.h)
position	Legend position. (See LEGEND_POSITION in legend.h)
alpha	Legend alpha (transparency). Default value is 160.

Parameters

size	a pointer to a QSize containing the size of images. If a null pointer is supplied, the SkyMap size is used.

Note

If size is larger than the skymap size, then the sky image is padded; if it is smaller, then it is cropped. No rescaling is done.
