Detailed Description
Helps download a DSS image.
- Note
- This object is designed to commit suicide (calls QObject::deleteLater() )! Never allocate this using anything but new – do not allocate it on the stack! This is ideal for its operation, as it deletes itself after downloading.

Constructor & Destructor Documentation
◆ KSDssDownloader() [1/2]
|
explicit |
Constructor.
Definition at line 17 of file ksdssdownloader.cpp.
◆ KSDssDownloader() [2/2]
KSDssDownloader::KSDssDownloader | ( | const SkyPoint *const | p, |
const QString & | destFileName, | ||
const std::function< void(bool)> & | slotDownloadReady, | ||
QObject * | parent = nullptr ) |
Constructor that initiates a "standard" DSS download job, calls the downloadReady slot, and finally self destructs.
- Note
- Very important that if you create with this constructor, the object will self-destruct. Avoid keeping pointers to it, or things may segfault!
Definition at line 29 of file ksdssdownloader.cpp.
Member Function Documentation
◆ getDSSURL() [1/3]
|
static |
Create a URL to obtain a DSS image for a given RA, Dec.
- Parameters
-
ra The J2000.0 Right Ascension of the point dec The J2000.0 Declination of the point width The width of the image in arcminutes height The height of the image in arcminutes type_ The image type, either gif or fits. version_ string describing which version to get md If a valid pointer is provided, fill with metadata
- Note
- This method resets height and width to fall within the range accepted by DSS
- Moved from namespace KSUtils (–asimha, Jan 5 2016)
- Valid versions are: dss1, poss2ukstu_red, poss2ukstu_ir, poss2ukstu_blue, poss1_blue, poss1_red, all, quickv, phase2_gsc2, phase2_gsc1. Of these, dss1 uses POSS1 Red in the north and POSS2/UKSTU Blue in the south. all uses the best of a combined list of all plates.
Definition at line 120 of file ksdssdownloader.cpp.
◆ getDSSURL() [2/3]
|
static |
High-level method to create a URL to obtain a DSS image for a given SkyPoint.
- Note
- If SkyPoint is a DeepSkyObject, this method automatically decides the image size required to fit the object.
- Moved from namespace KSUtils (–asimha, Jan 5 2016)
Definition at line 49 of file ksdssdownloader.cpp.
◆ getDSSURL() [3/3]
|
static |
High-level method to create a URL to obtain a DSS image for a given SkyPoint.
- Note
- This method includes an option to set the height, but uses default values for many parameters
Definition at line 99 of file ksdssdownloader.cpp.
◆ startSingleDownload()
void KSDssDownloader::startSingleDownload | ( | const QUrl | srcUrl, |
const QString & | destFileName, | ||
KSDssImage::Metadata & | md ) |
Stateful single-download of a supplied URL.
Use when the flexibility is required
- Note
- Does not self-delete this object. Construct with default constructor, and delete as usual.
- Parameters
-
srcUrl source DSS URL to download destFileName destination image file (will be of PNG format) md DSS image metadata to write into image file
- Note
- emits downloadComplete with success state when done
Definition at line 218 of file ksdssdownloader.cpp.
◆ writeImageWithMetadata()
|
static |
Write image metadata into file.
