Detailed Description
Backends for exporting a sky image, either raster or vector, with a legend.
Definition at line 23 of file imageexporter.h.
Constructor & Destructor Documentation
◆ ImageExporter()
|
explicit |
Constructor.
Definition at line 22 of file imageexporter.cpp.
◆ ~ImageExporter()
|
override |
Destructor.
Definition at line 258 of file imageexporter.cpp.
Member Function Documentation
◆ exportImage
|
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
- 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()
|
inline |
- Returns
- last error message
Definition at line 41 of file imageexporter.h.
◆ getLegend
|
inlineslot |
- Returns
- a pointer to the legend used
Definition at line 85 of file imageexporter.h.
◆ includeLegend
|
inlineslot |
Include legend?
- Parameters
-
include The legend will be included if the flag is set to true
Definition at line 67 of file imageexporter.h.
◆ setLegendAlpha
|
slot |
Set legend transparency.
- Parameters
-
alpha Transparency level
Definition at line 271 of file imageexporter.cpp.
◆ setLegendProperties
|
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. include Include the legend?
Definition at line 241 of file imageexporter.cpp.
◆ setRasterOutputSize
|
slot |
Set the size of output raster images.
- 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.
