Draws objects onto an image at given locations using the specified galaxy model and shear model. The galaxy model determines the underlying functional shape and photon distribution of the galaxies, and the shear model determines the amount of shear bias, based on the galaxy's location in the image.

This module modified the values inside the Image/Data array.

Currently the module only handles galaxy objects. Objects of other types will be ignored.

Parameters

Name	Type	Description
GalTag	string	Tag name of the galaxy model to use.
ShearTag	string	Tag name of the shear model to use.
BufferWidth	int	Width of the temporary buffer used to draw images.
Seed	int	If set, use as seed for random number generator. If not set, a random seed is used.

Inputs

Name	Type	Description
Image/Width	int	Width of the image, in pixels.
Image/Height	int	Height of the image, in pixels.
Image/Data	double*	Pixel value array.
Image/ObjectX	double*	Array of x-coordinates of objects, in pixel units.
Image/ObjectY	double*	Array of y-coordinates of objects, in pixel units.
Image/ObjectTypes	int*	Array of types of objects, as specified in SimConst.h
Image/NumberObjs	int	Number of objects placed in image. This will be the length of the above arrays.

Outputs

Name	Type	Description
Realization/Seed	int	Seed value used to generate images.
