Constructor & Destructor Documentation

◆ ImageExporter()

ImageExporter::ImageExporter ( QObject * parent = nullptr)
explicit

Constructor.

Definition at line 22 of file imageexporter.cpp.

◆ ~ImageExporter()

ImageExporter::~ImageExporter ( )
override

Destructor.

Definition at line 258 of file imageexporter.cpp.

Member Function Documentation

◆ exportImage

bool ImageExporter::exportImage ( QString url)
slot

Exports an image with the defined settings.

Parameters
urlURL of the exported image
Returns
false if the URL was a network location and uploading to the network location failed
Note
This method calls an SVG backend instead if the file extension is svg. Otherwise, it draws raster.

Definition at line 188 of file imageexporter.cpp.

◆ getLastErrorMessage()

QString ImageExporter::getLastErrorMessage ( ) const
inline
Returns
last error message

Definition at line 41 of file imageexporter.h.

◆ getLegend

Legend * ImageExporter::getLegend ( )
inlineslot
Returns
a pointer to the legend used

Definition at line 85 of file imageexporter.h.

◆ includeLegend

void ImageExporter::includeLegend ( bool include)
inlineslot

Include legend?

Parameters
includeThe legend will be included if the flag is set to true

Definition at line 67 of file imageexporter.h.

◆ setLegendAlpha

void ImageExporter::setLegendAlpha ( int alpha)
slot

Set legend transparency.

Parameters
alphaTransparency level

Definition at line 271 of file imageexporter.cpp.

◆ setLegendProperties

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
typeLegend type. (See enum LEGEND_TYPE in legend.h)
orientationLegend orientation. (See LEGEND_ORIENTATION in legend.h)
positionLegend position. (See LEGEND_POSITION in legend.h)
alphaLegend alpha (transparency). Default value is 160.
includeInclude the legend?

Definition at line 241 of file imageexporter.cpp.

◆ setRasterOutputSize

void ImageExporter::setRasterOutputSize ( const QSize * size)
slot

Set the size of output raster images.

Parameters
sizea 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.
