pooling(self, inputs)

source code

Create a pool using all CPUs and farm out the calculations.

Parameters:

inputs (list(tuple(str))) - List containing argument tuples for JPG calculation.

calculate(self, args)

source code

Calculate JPGs.

Parameters:

args (args) - Arguments for createCompressedImage.

createCompressedImage(self, fileName, dateVersStr, jpgPath)

source code

Creates a JPEG compressed image of the given FITS file.

Parameters:

fileName (str) - Full path to the FITS file.
dateVersStr (str) - Date-version string of the processed file batch.

getArrowCoords(self, fitsFileHDUs, arrays)

source code

Calculate unit coords for the N/E arrows.

Parameters:

fitsFileHDUs (pyfits HDU list) - The FITS file HDU list the coords should be created for.
arrays (list) - List of available HDUs.

makeOverlay(self, image, arrows, thetaRad=0.0)

source code

Make the N/E axes overlay.

Parameters:

image (PIL image object) - The image for which the overlay is produced.
thetaRad (double) - Rotation angle of the overlay in radians.thetaRad=0.0

Returns: PIL image object

The updated image.

coordAdd(self, coord1, coord2)

source code

Routine to add one coordinate pair to another or a list of coordinates.

Parameters:

coord1 (tuple) - Single coordinate (x,y).
coord2 (tuple or list(tuples)) - Single coordinate or list of coordinates.

Returns: tuple or list(tuples)

Added coordinates.

coordRot(self, coord, thetaRad)

source code

Routine to rotate coordinate pairs (x,y).

Parameters:

coord (tuple or list(tuples)) - Single coordinate or list of coordinates.
thetaRad (double) - Rotation angle in radians.

Returns: tuple or list(tuples)

Rotated coordinates.
