Detailed Description

Helps download a DSS image.

Author

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]

KSDssDownloader::KSDssDownloader ( QObject parent = nullptr)
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]

QString KSDssDownloader::getDSSURL ( const dms ra,
const dms dec,
float  width = 0,
float  height = 0,
const QString type_ = "gif",
const QString version_ = "all",
struct KSDssImage::Metadata md = nullptr 
)
static

Create a URL to obtain a DSS image for a given RA, Dec.

Parameters
raThe J2000.0 Right Ascension of the point
decThe J2000.0 Declination of the point
widthThe width of the image in arcminutes
heightThe height of the image in arcminutes
type_The image type, either gif or fits.
version_string describing which version to get
mdIf 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]

QString KSDssDownloader::getDSSURL ( const SkyPoint *const  p,
const QString version = "all",
struct KSDssImage::Metadata md = nullptr 
)
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]

QString KSDssDownloader::getDSSURL ( const SkyPoint *const  p,
float  width,
float  height = 0,
const QString version = "all",
struct KSDssImage::Metadata md = nullptr 
)
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
srcUrlsource DSS URL to download
destFileNamedestination image file (will be of PNG format)
mdDSS image metadata to write into image file
Note
emits downloadComplete with success state when done

Definition at line 218 of file ksdssdownloader.cpp.

◆ writeImageWithMetadata()

bool KSDssDownloader::writeImageWithMetadata ( const QString srcFile,
const QString destFile,
const KSDssImage::Metadata md 
)
static

Write image metadata into file.
